Commit 6abb7e3 updates the markers when the chapters change, but it
doesn't update their relative position at the bar when the duration
changes.
This means that adding chapters to a live stream would result in
corresponding chapter markers which were static while the duration
changed and thus their positions became incorrect over time until the
OSC was reinitialized.
This is fixed by observing the duration property if chapters are present
and reinitializing the OSC when the duration changes.
The live_markers user option, which determines whether the duration
property is observed when there are chapters, has been added in order to
allow disabling this behaviour as calling request_init() frequently
might have some impact on low-end systems.
The impact of request_init() on render() was measured to increase from
1-1.5 ms to 2-3 ms on a 2010 MacBook Air, while the impact was neglible
on a 2016 Surface Book (increasing only to an average of 1.4 ms from
1.3 ms for n=1500 render cycles).
The live_markers option is enabled by default.

This is the Vulkan equivalent of the drm context for OpenGL, with
the big difference that it's implemented purely in terms of Vulkan
calls and doesn't actually require drm or kms.
The basic idea is to identify a display, mode, and plane on a device,
and then create a display backed surface for the swapchain. In theory,
past that point, everything is the same, and this is in fact the case
on Intel hardware. I can get a video playing on a vt.
On nvidia, naturally, things don't work that way. Instead, nvidia only
implemented the extension for scenarios where a VR application is
stealing a display from a running window system, and not for
standalone scenarios. With additional code, I've got this scenario to
work but that's a separate incremental change.
Other people have tested on AMD, and report roughly the same behaviour
as on Intel.
Note, that in this change, the VT will not be correctly restored after
qutting. The only way to restore the VT is to introduce some drm
specific code which I will illustrate in a separate change.

The VkDisplayKHR context type requires making calls against the
physical device before the libplacebo context is initialised.
That means we can't simply use the physical device object that
libplacebo would create - instead we have to create a separate one,
but make sure it's referring to the same physical device.
To that end, we need the device name that the user may have requested
so we can pass it on.

This moves the JSON parsing above the main youtube-dl error-handling
block and integrates parsing errors into that block. Now, if a parsing
error occurs, youtube-dl's stderr will be logged as it is with other
errors. This also catches errors that cause youtube-dl to output
"null", which would previously be mishandled as a parsing error and
crash ytdl_hook when it attempted to concatenate the error string from
parse_json.

This was originally just a bugfix for a race condition, but the scope
expanded a bit. Currently, the wayland code does a prepare_read ->
dispatch_pending -> display_flush -> read_events -> dispatch_pending
routine that's basically straight from the wayland client API
documentation. This essentially just queues up all the wayland events
mpv has and dispatches them to the compositor. We do this for blocking
purposes on every frame we render. A very similar thing is done for
wait_events from the VO.
This code can pretty easily be unified and split off into a separate
function, vo_wayland_dispatch_events. vo_wayland_wait_frame will call
this function in a while loop (which will break either on timeout or if
we receive frame callback from the compositor). wait_events needs to
just check this in case we get some state change on the wakeup_pipe
(i.e. waking up from the paused state).
As for the actual bugfix part of this, it's a slight regression from
c26d833. The toplevel config event always forced a redraw when a surface
became activated again. This is for something like displaying cover art
on a music file. If the window was originally out of view and then later
brought back into focus, no picture would be rendered (i.e. the window
is just black). That's because something like cover art is just 1 frame
and the VO stops doing any other additional rendering. If you miss that
1 frame, nothing would show up ever again. The fix in this case is to
always just force a redraw when the mpv window comes back into view.
Well with the aforementioned commit, we stopped doing
wl_display_roundtrip calls on every frame. That means we no longer do
roundtrip blocking calls. We just be sure to queue up all of the events
we have and then dispatch them. Because wayland is fundamentally an
asynchronous protocol, there's no guarantee what order these events
would be processed in. This meant that on occasion, a
vo_wayland_wait_frame call (this could occur multiple times depending on
the exact situation) would occur before the compositor would send back
frame callback. That would result in the aforementioned bug of having
just a black window. The fix, in this case, is to just do a
vo_wayland_wait_frame call directly before we force the VO to do a
redraw. Note that merely dispatching events isn't enough because we
specifically need to wait for the compositor to give us frame callback
before doing a new render.
P.S. fix a typo too.

And also change the existing WM_KILLFOCUS handler to return 0 instead
of 'break' (which later calls DefWindowProcW), as MSDN says we should
do for WM_{KILL,SET}FOCUS.
It seems that the 'focused' property is now supported by all main VOs:
x11, macOS, wayland, Windows.
TCT/sixel/caca probably don't support it, and unknown with SDL.

When the OSC initializes, it checks whether the current video has
chapters, and if it does not, it disables its chapter functionality
(chapter buttons are grayed out and unusable, chapter indicators don't
show on the seek bar). If another script changed the chapter list
after the video has loaded, those changes would be ignored by the OSC
until some other event causes it to re-initialize, because it did not
observe the chapter list property. This is fixed by adding
observation of chapter-list alongside the other properties that
trigger re-initialization.

Avoiding blindly copying the codec_tag between different formats allows

Not only does this have semantics that make far more sense, it also has
a default that makes far more sense. (Equivalent to the old
`icc-contrast=inf`)
This removes the weird 1000:1 contrast default assumption which
especially broke perceptual profiles and also screws things up for
OLED/CRT/etc.
Should probably close some issues but I honestly can't be bothered to
figure out which of the thousands colorimetry-related issues are
affected.

Take two. f4e89dd went wrong by moving vo_wayland_wait_frame before
start_frame was called. Whether or not this matters depends on the
compositor, but some weird things can happen. Basically, it's a
scheduling issue. vo_wayland_wait_frame queues all events and sends them
to the server to process (with no blocking if presentation time is
available). If mpv changes state while rendering (and this function is
called before every frame is drawn), then that event also gets
dispatched and sent to the compositor. This, in some cases, can cause
some funny behavior because the next frame gets attached to the surface
while the old buffer is getting released. It's safer to call this
function after the swap already happens and well before mpv calls its
next draw. There's no weird scheduling of events, and the compositor log
is more normal.
The second part of this is to fix some stuttering issues. This is mostly
just conjecture, but probably what was happening was this thing called
"composition". The easiest way to see this is to play a video on the
default audio sync mode (probably easiest to see on a typical 23.976
video). Have that in a window and float it over firefox (floating
windows are bloat on a tiling wm anyway). Then in firefox, do some short
bursts of smooth scrolling (likely uses egl). Some stutter in video
rendering could be observed, particularly in panning shots.
Compositors are supposed to prevent tearing so what likely was happening
was that the compositor was simply holding the buffer a wee bit longer
to make sure it happened in sync with the smooth scrolling. Because the
mpv code waits precisely on presentation time, the loop would timeout on
occasion instead of receiving the frame callback. This would then lead
to a skipped frame when rendering and thus causing stuttering.
The fix is simple: just only count consecutive timeouts as not receiving
frame callback. If a compositor holds the mpv buffer slightly longer to
avoid tearing, then we will definitely receive frame callback on the
next round of the render loop. This logic also appears to be sound for
plasma (funfact: Plasma always returns frame callback even when the
window is hidden. Not sure what's up with that, but luckily it doesn't
matter to us.), so get rid of the goofy 1/vblank_time thing and just
keep it a simple > 1 check.

Checking against 1.0 is wrong for this code, because it's in an absolute
luminance scale relative to reference white. We should be normalizing
this by `dst.sig_peak`.

This is actually a very nice simplification that should have been
thought of years ago (sue me). In a nutshell, the story with the
wayland code is that the frame callback and swap buffer behavior doesn't
fit very well with mpv's rendering loop. It's been refactored/changed
quite a few times over the years and works well enough but things could
be better. The current iteration works with an external swapchain to
check if we have frame callback before deciding whether or not to
render. This logic was implemented in both egl and vulkan.
This does have its warts however. There's some hidden state detection
logic which works but is kind of ugly. Since wayland doesn't allow
clients to know if they are actually visible (questionable but
whatever), you can just reasonably assume that if a bunch of callbacks
are missed in a row, you're probably not visible. That's fine, but it is
indeed less than ideal since the threshold is basically entirely
arbitrary and mpv does do a few wasteful renders before it decides that
the window is actually hidden.
The biggest urk in the vo_wayland_wait_frame is the use of
wl_display_roundtrip. Wayland developers would probably be offended by
the way mpv abuses that function, but essentially it was a way to have
semi-blocking behavior needed for display-resample to work. Since the
swap interval must be 0 on wayland (otherwise it will block the entire
player's rendering loop), we need some other way to wait on vsync. The
idea here was to dispatch and poll a bunch of wayland events, wait (with
a timeout) until we get frame callback, and then wait for the compositor
to process it. That pretty much perfectly waits on vsync and lets us
keep all the good timings and all that jazz that we want for mpv. The
problem is that wl_display_roundtrip is conceptually a bad function. It
can internally call wl_display_dispatch which in certain instances,
empty event queue, will block forever. Now strictly speaking, this
probably will never, ever happen (once I was able to to trigger it by
hardcoding an error into a compositor), but ideally
vo_wayland_wait_frame should never infinitely block and stall the
player. Unfortunately, removing that function always lead to problems
with timings and unsteady vsync intervals so it survived many refactors.
Until now, of course. In wayland, the ideal is to never do wasteful
rendering (i.e. don't render if the window isn't visible). Instead of
wrestling around with hidden states and possible missed vblanks, let's
rearrange the wayland rendering logic so we only ever draw a frame when
the frame callback is returned to use (within a reasonable timeout to
avoid blocking forever).
This slight rearrangement of the wait allows for several simplifications
to be made. Namely, wl_display_roundtrip stops being needed. Instead, we
can rely entirely on totally nonblocking calls (dispatch_pending, flush,
and so on). We still need to poll the fd here to actually get the frame
callback event from the compositor, but there's no longer any reason to
do extra waiting. As soon as we get the callback, we immediately draw.
This works quite well and has stable vsync (display-resample and audio).
Additionally, all of the logic about hidden states is no longer needed.
If vo_wayland_wait_frame times out, it's okay to assume immediately that
the window is not visible and skip rendering.
Unfortunately, there's one limitation on this new approach. It will only
work correctly if the compositor implements presentation time. That
means a reduced version of the old way still has to be carried around in
vo_wayland_wait_frame. So if the compositor has no presentation time,
then we are forced to use wl_display_roundtrip and juggle some funny
assumptions about whether or not the window is hidden or not. Plasma is
the only real notable compositor without presentation time at this stage
so perhaps this "legacy" mechanism could be removed in the future.

when using the bundle with activated big enough cache, very slow and
wasteful memory allocations lead to jittery playback and lot of dropped
frames. the cache had to have a certain size so it would constantly
allocate new memory to reproduce this. this never happens when started
from the terminal.
the source of the problem is a different malloc allocation policy,
MALLOC_NANO, that allocated a huge amount of virtual memory without
actually using it. the usage was between 0% to 25% of that virtual
memory. the binaries allocation policy on the other hand used >80% of
that allocated virtual memory and was a lot more efficient, it would use
MALLOC_TINY instead.
this is fixed by setting the MallocNanoZone environment variable to 0
to use the V1 of the allocation policy. when started from the bundle via
launchd this is forced to 1 and V2 policy which causes this problem.

Apple open source site:

and if the all_formats option is not set to true (does anyone even use

When trying to use completion for mpv binaries specified with some shell
glob, e.g. ~/dev/mpv/build/mpv, the current code doesn't substitute the
homedir prefix into the path name, resulting in runtime errors about
the file '~/dev/mpv/build/mpv' not being found.
The simple fixed is to use $~var instead of $var whenever expanding the

performed when executing the command.

Switching to a new file while keeping the AO didn't update the volume.
While there's an explicit audio_update_volume() call in
reinit_audio_chain_src(), it doesn't work, because at that point
ao_chain->ao is still NULL, and it does nothing. That's pretty weird and
might cause other problems (what happens if you try to mute while the AO
is "floating"?). Regarding gapless, trying to use the AO gain for
replaygain is also gross nonsense, because the new replaygain computed
gain would affect audio from the previous file. It looks like replaygain
should be in an af_volume filter maybe. On the other hand, I enjoy
setting ridiculous replaygain-preamp values and compensating with a low
volume setting, which would not work well if both gains were applied to
the audio independently.
For now, just add the missing call. This is orthogonal to fixing
replaygain "properly".

This reverts commit 3239e41277173bace5ecc2a22910c4660642429c.
I'm fairly sure this is wrong, and my next commit should fix it
properly. I'm not really sure, though. Normally, the AO is set again
by reinit_audio_filters_and_output() after the new audio chain has
decoded a frame and knows the new format. The reason replaygain (and
apparently the thing the reverted commit tried to fix) didn't work is
because they work asynchronously to the audio played by the AO (i.e.
buggy and hard to fix).

This commit describes more accurately what currently gets disabled
by this option - specifically also keys from mp.add_key_binding.
It's not necessarily the best behavior because libmpv clients might
want to disable mpv's own builtin keybindings while still allowing
scripts to define keys which `input.conf' can override.
In the future we might exclude mp.add_key_binding from this option,
but for now at least document this option accurately.

This fixes a bug where using boxvideo with showfullscreen=no or
showwindowed=no resulted in the margins not resetting when the OSC
wasn't visible.
For example, using:
script-opts=osc-visibility=always,osc-boxvideo=yes,osc-showfullscreen=no
and then going fullscreen would make the OSC disappear but the video
margins would remain. This is because boxvideo was missing a dependence
on the showfullscreen and showwindowed user options.
This is fixed by adding the corresponding conditions to update_margins()
and setting state.marginsREQ on fullscreen changes. update_margins() is
called on tick() if there's a margins update pending, which guarantees
the boxvideo margins are reset appropriately.

It turns out that if a user specifies fullscreen=yes and a width/height
in an autoprofile, the compositor can execute its toplevel listener
event. This can happen before we have any mpv window rendered at all so
we end up performing a bunch of geometry operations and state checks
when we shouldn't. It subtly messes up a lot of things like state
detection. Just return from this function if the geometry has no width
or height yet.

Clearing state.osd.data with an empty string at render_wipe() fixes an
issue where changing the OSC visibility from "never" directly to
"always" didn't immediately update the display when the player was
paused. This could be verified by starting the player with
`--script-opts=osc-visibility=always --pause` and then running
`script-message osc-visibility never` followed by
`script-message osc-visibility always`.
Removing the overlay without changing the contents meant the overlay
wouldn't update and display when enabled again until the fields changed
in some way (e.g. seeking, mousing over the OSC area, etc.). Clearing
state.osd.data before removal of the OSC makes sure set_osd doesn't

is now different.
render_wipe() is now also used when the OSC needs to be cleared at
tick() as using set_osd to clear it with an empty string did not call
state.osd:remove() which can allow cleanups related to bitmap memory
allocations etc.

this is a regression of af26402, where we changed the geometry
calculation to use the visible frame and consider its origin. though the
origin is not screen relative but relative to the main screen. the rest
of the code expects a screen relative rectangle. because of that windows
would be placed out of the screen bounds when not on the main screen.
recalculate to origin to be screen relative and use those values for the
rest of the calculations. to make the code a bit more comprehensible
be a bit more explicit about what is done where with temporary variables
and comments. also move the mp_rect calculation that moves the origin
and flips the y position to a separate function, so we can reuse it
later.

The fit_on_screen logic was a bit twisted. Simplify it a bit
and update few comments to explain better what it's used for.
Note that the new logic is not identical to before, but its intent
should now be clearer. This means there might be regressions or
improvements at edge cases. If followup fixes are needed, then we
should keep the intent clear. Most likely though that it's fine.

fit_on_screen is called only from reinit_window_state.
Move the yes/no logic unmodified from fit_on_screen to
reinit_window_state, and remove the w32->parent condition because it's

Previously, because the video (client area) was centered but the top
and bottom borders are uneven (title is taller), then if the window
is shrunk vertically to just-fit the desktop - the top edge of the
title bar ended above the top edge of the display.
This is a state which Windows prevents during manual move, but
apparently it's not rejected at the Windows API.
Now we ensure it doesn't happen, and nudge the window down to align
the top edges if necessary.
This is a commulative regression of commits 981048e0 and 364af7c6.
To clarify functionality, this includes a no-op change: fit_rect was
renamed to fit_rect_size and it now takes explicit width and height,
because it only used the width/height of rc2 anyway.

The accurate description of this option was:
- fit-border is enabled by default. When disabled, it adds a bug where
if the window has borders and mpv shrinks it to fit the desktop, then
the calculation ignores the borders and adds incorrect video crop.
The option was added at commits 70f64f3c and 949247d6, in order to
solve an issue (#2935) where if mpv wanted to display a video with
size WxH, then w32_common.c incorrectly set the window to WxH, while
down-scaling the video slightly to fit (even with small sizes).
It was addressed with a new option which is enabled by default, but
does the right thing (sets the client area to WxH) only when disabled,
so that everyone who prefers their video slightly downscaled could
keep their default behavior.
(#2935 also addressed an off-by-one issue, fixed before fit-border)
While disabling the option did avoid unnecessary downscaling, it also
added a bug when disabled: the borders are no longer taken into
account when the size is too big for the desktop. Most users don't
notice and are unaffected as it's enabled by default.
Shortly later (981048e0) the core issue is fixed, and now the client
area is correctly set to WxH instead of the window (and together with
the three following commits which center the video, adds a new bug
where the window title can be outside the display - addressed next).
However, fit-border remained, now without any effect, except that it
still has the same bug when disabled and the window is too big.
Later code changes and refactoring preserved this issue with great
attention to details, and it remained in identical form until now.
Simply rip out fit-border.

See #8137 for justification.
This is not ideal, because a large cache results in a lot of `strcmp`
invocations for every single shader invocation. But it's way better than
resulting in a lot of shader recompilations for every single shader
invocation.
The only reason I don't want to uncap it altogether is because there are
conceivable edge cases in which users load dynamically generated shaders
with updated parameters (indeed, I've seen IRC discussions to this
effect), and in this case, we don't want to grow the cache infinitely as
a result of something like a floating point parameter being continuously
updated. (Never mind that this *would* actually trigger worst case
behavior for the `strcmp`, since the updated float constant is likely to
be near the bottom of the shader body)
Whatever. vo_placebo will liberate us all in the end.

The wayland code uses a heuristic to determine whether or not the mpv
window is hidden since the xdg-shell protocol does not provide a way for
a client to directly know this. We don't render with the frame callback
function for various, complicated reasons but the tl;dr is that it
doesn't work well with mpv's core (maybe an essay should be written on
this one day).
Currently, the aforementioned heuristic considers a window hidden if we
miss more frames in a row than the display's current refresh rate
(completely arbitrary number). However, the wayland protocol does allow
for the display's refresh rate to be 0 in certain cases (like a virtual
output). This completely wrecks the heuristic and basically causes only
every other frame to be rendered (real world example: nested sway
sessions).
Instead let's slightly redesign this mechanism to be a little smarter.
For coming up with the vblank time (to predict when to timeout on the
wait function), instead use the vsync interval calculated using
presentation time. That is the most accurate measure available. If that
number is not available/invalid, then we try to use the vsync interval
predicted by the presentation event.
If we still don't have that (i.e. no presentation time supported by the
compositor), we can instead use the old way of using the expected vsync
interval from the display's reported refresh rate. If somehow we still
do not have a usable number, then just give up and makeup shit. Note
that at this point we could technically ask the vo for the estimated
vsync jitter, but that would involve locking/unlocking vo which sounds
horrifying. Ideally, you never reach here.
See https://github.com/swaywm/wlroots/issues/2566 for the actual target
of this fix. wlroots uses presentation time so in practice we are mostly
just using that calculated vsync interval number.

Seems to be a slight corner case with the audio API rewrite. When
switching from one file to another one, the volume of the ao would never
be set because the audio chain's ao wasn't set. This caused a bug with
the reset-set-on-file option. The volume/property would be correctly set
internally, but the gain was not actually set when the file switched.
Fixes #8287.

The wayland output listener can update whenever something about the
output changes (resolution, scale). Currently, the mpv VO updates
correctly when the refresh rate changes, but changes of both scale and
resolution were not considered. This causes a bug in certain cases like
the mouse surface not being shown at certain scale factors due to the
cursor scale not being updated correctly. Also autofit type options
would not update if the resolution changes.
To fix this, we must always reset the window geometry and wl scaling
whenever the output event occurs on wl->current_output. There is no way
to know precisely what changed from the previous state, so all of the
parameters must be reset and then resized.
As an aside, this apparently doesn't fix all cursor problem as there's
apparently a bug in libwayland-cursor(*). It's still something we should
be doing regardless.

So apparently this property had existed since 2019. Internally, it's
used as a part of the console.lua script for scaling. Yours truly
somehow didn't bat an eye at the fact that the text in the console was
super small (made worse by the fact that xwayland does scale) and just
ignored it for all this time. Oh well.
To report dpi changes to mpv's core, we need to use VO_EVENT_DPI in a
couple of places. One place is, of course, the surface listener if the
scale value reported by the wayland server changes. The other place is
in the very first reconfig since mpv's core will not find the correct
scale value until we actually get a wl_output from the wayland server.

Before this commit, the user could specify a printf format string
which wasn't verified, and could result in:
- Undefined behavior due to missing or non-matching arguments.
- Buffer overflow due to untested result length.
The offending code was added at commit 103a9609 (2002, mplayer svn):
git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@4566 b3059339-0415-0410-9bf9-f77b7e298cf2
It moved around but was not modified meaningfully until now.
Now we reject all conversion specifiers at the format except %%
and a simple subset of the valid specifiers. Also, we now use
snprintf to avoid buffer overflow.
The format string is provided by the user as part of mf:// URI.

When mpv attempts to play a video that is, on average, 60 FPS on a
display that is not exactly 60.00 Hz, two options try to fight each
other: `video-sync-max-video-change` and `interpolation-threshold`.
Normally, container FPS in something such as an .mp4 or a .mkv is
precise enough such that the video can be retimed exactly to the display
Hz and interpolation is not activated.
In the case of something like certain live streaming videos or other scenario
where container FPS is not known, the default option of 0.0001 for
`interpolation-threshold` is extremely low, and while
`video-sync-max-video-change` retimes the video to what it approximately
knows as the "real" FPS, this may or may not be outside of
`interpolation-threshold`'s logic at any given time, which causes
interpolation to be frequently flipped on and off giving an appearance
of stuttering or repeated frames that is oftern quite jarring and makes
a video unwatchable.
This commit changes the default of `interpolation-threshold` to 0.01,
which is the same value as `video-sync-max-video-change`, and guarantees
that if the user accepts a video being retimed to match the display,
they do not additionally have to worry about a much more
precise interpolation threshold randomly flipping on or off. No internal
logic is changed so setting `interpolation-threshold` to -1 will still
disable this logic entirely and always enable interpolation.
The documentation has been updated to reflect this change and give
context to the user for which scenarios they might want to disable
`interpolation-threshold` logic or change it to a smaller value.

Today, validation is only possible for string type options. But there's
no particular reason why it needs to be restricted in this way, and
there are potential uses, to allow other options to be validated
without forcing the option to have to reimplement parsing from
scratch.
The first part, simply making the validation function an explicit
field instead of overloading priv is simple enough. But if we only do
that, then the validation function still needs to deal with the raw
pre-parsed string. Instead, we want to allow the value to be parsed
before it is validated. That in turn leads to us having validator
functions that should be type aware. Unfortunately, that means we need
to keep the explicit macro like OPT_STRING_VALIDATE() as a way to
enforce the correct typing of the function. Otherwise, we'd have to
have the validator take a void * and hope the implementation can cast
it correctly.
For help, we don't have this problem, as help doesn't look at the
value.
Then, we turn validators that are really help generators into explicit
help functions and where a validator is help + validation, we split
them into two parts.
I have, however, left functions that need to query information for both
help and validation as single functions to avoid code duplication.
In this change, I have not added an other OPT_FOO_VALIDATE() macros as
they are not needed, but I will add some in a separate change to
illustrate the pattern.

There was a simple oversight that meant audio outputs were
uninitialized during an encoding, which is not allowed, the encoding
would stop with numerous errors.
I added a single line to prevent the call of uninit_audio_out in
reinit_audio_chain if the encoder was active and this appears to have
fixed the problem without breaking anything else.

Now loading cover art through mp_add_external_file requires an

commands end up being marked as cover art when they move through
mp_add_external_file, as originally changed in 55d7f9ded197d82d172b7baf74b1a07640361ae8 .
Additionally, this lets us clean up some logic that would otherwise be

the logic had been kept split from mp_add_external_file.

The wayland code takes mouse dragging into account in order to trigger a
client-side request for a window move or window resize. According to the
xdg-shell spec*, "[t]he server may ignore move[/resize] requests
depending on the state of the surface (e.g. fullscreen or maximized)".
Since it is not actually a hard requirement, that means the compositor
could actually respond to a clientside move/resize request even if the
mpv window was fullscreen. For example, it was pointed out that in sway,
if mpv is a floating window, you could drag it around off screen even
though the window is fullscreen.
This kind of behavior does not really have any practical use. A user can
should pan a video if he/she wishes to move its orientation while
fullscreen (or maximized for that manner). Naturally, a maximized or
fullscreened window should never be manually resized (every compositor
likely ignores this anyway). The fix is to simply just not trigger the
smecial mouse dragging case if the wayland surface is fullscreened or
maximized.

It's about a year old, and packaged pretty much everywhere that bothers
to package libplacebo at all. Older versions are only a thing on LTS,
which will probably also use older mpv so it works out.
Starting with v2.72.0, libplacebo validates all of its parameters
internally and turns them into function failures. Doing it twice is
awfully redundant, so we can drop the parameter validation.
Also allows us to drop some preprocessor macros.

the slider on the touch bar was always updated when any of the related
properties changed their value. this is partially dependent on the
refresh rate of the video, in the case of time-pos. too many updates to
touch bar impact the render performance.
to prevent this we only update the slider when necessary, when the touch
bar or the touch bar item is visible. the touch bar items only need a
granularity of seconds without any decimals, but the time-pos property
provides a granularity with decimals. we floor those values and only
update the touch bar items when we have at least a 1 second difference.
we also check for the visibility of the touch bar and its items.

the pointer used to initialise the respective structs is only guaranteed
to be alive within this constructor. the struct itself is used later and
the data it points to, is not guaranteed to be the same.
to fix this we define a scope that pointer is definitely valid and use
it within this scope. a helper function was added to get the pointers
for several data at once. otherwise we would need to nest
withUnsafeMutableBytes several times, which would make it hard to read.

Where X is any ASCII char chosen by the user. An argument is only
interpreted as custom-quoted if it starts with '!' and the line doesn't
end right after it. Custom quotes don't interpret backslash-escape.
This change only affects command arguments which mpv parses (not array
commands), and not tokens before the arguments (where applicable - key

Should result in: "You manually enabled the feature 'lua', but the
autodetection check failed."
The moved bit of code was probably intended to do that all along, but it
was running too late, so the code that actually checked for Lua didn't
know it was explicitly asked for and quietly disabled it if not found.

currently we use the whole screen rectangle to calculate the window
geometry. this doesn't take the menu bar or the Dock into account.
by default use the visible screen rectangle instead. this is also a
change in behaviour, since the window can't be placed outside of this
rectangle anymore. also add an option to change to the old behaviour,
because it can still be useful in certain cases, like placing the window
directly underneath the menu bar when used a desktop background.

when exiting fullscreen we set the window frame to a aspect fit frame of
the fullscreen frame to prevent aspect ration problems when animating.
though that intermediate frame was set too early and before the system
knew we already exited the fullscreen. because of that the frame we set
could not be properly set and its origin was defaulted to the bottom
left corner for exactly one display refresh and only after that the
wanted frame was set. this led to a (dark) grey area on the right or
top depending on the aspect ratio difference of the screen and video.
to prevent this set the intermediate frame in the animation group to
make it sync with the system's fullscreen behaviour.

Originally when presentation time was implemented, the frame callback
and presentation feedback functions were called in each rendering api's
separate backend (egl and vulkan). This meant that their respective
structs were basically copy and pasted across both files. Plus later
vo_wlshm started using frame callbacks too. Things got refactored a few
times and it turns out there's actually no need to have these things
separate anymore. The frame callback can just be initialized in
vo_wayland_init and then everything else will follow from there. Just
move all of this code to wayland_common and get rid of the duplication.
Sidenote: This means that vo_wlshm can actually receive presentation
feedback now. It's really simple to do so might as well. See the next
commit.

If the window is maximized, we can't change the size immediately. In
that case, we set a bool and wait for the state to change before
triggering the resize.

Additionally, do some cleanups in the resize/autofitting code to make
sure we don't do any wasteful VO_EVENT_RESIZE calls. Note that if
set_geometry is called, we must always perform a resize.

--alpha=yes doesn't affect only transparent videos and images, but also

backgrounds and had no idea that they already worked at least on
Wayland.
Background transparency will work on X11 when
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/2376 is
merged. It doesn't work on Windows. No idea about macOS. Either way,
this paragraph already says that it only works on certain environments

With the current wording, I thought that playlist-prefetch doesn't
prefetch the next url within a playlist of m3u8 urls, but it makes a big
difference, and I would have enabled it earlier if it wasn't for this
paragraph.
This makes it clear that you can prefetch any file, but that it won't
prefill the cache with the video data. This is true for any video,
there's nothing unique about HLS streams in the behavior of this option.

There's a bit of a catch-22 in the wayland backend. mpv needs to know
several things about the wl_output the surface is on (geometry, scale,
etc.) for lots of its options. You still have to render something
somewhere before you can know what wl_output the surface is actually on.
So this means that when initializing the player, it is entirely possible
to calculate initial parameters using the wrong wl_output. The surface
listener is what will eventually correct this and pick the correct
output. However not everything was technically working correctly in a
multi-output setup.
The first rule here is to rework find_output so that it returns a
vo_wayland_output instead of internally setting wl->current_output. The
reason is simply because the output found here is not guaranteed to be
the output the surface is actually on. Note that for initialization of
the player, we must set the output returned from this function as the
wl->current_output even if it is not technically correct. The surface
listener will fix it later.
vo_wayland_reconfig has to confusingly serve two roles. It must ensure
some wayland-related things are configured as well as setup things for
mpv's vo. The various functions are shuffled around and some things are
removed here which has subtle implications. For instance, there's no
reason to always set the buffer scale. It only needs to be done once
(when the wl->current_output is being created). A roundtrip needs to be
done once after a wl_surface_commit to ensure there are no configuration
errors.
surface_handle_enter is now handles two different things: scaling as
well as mpv's autofit/geometry options. When a surface enters a new
output, the new scaling value is applied to all of the geometry-related
structs (previously, this wasn't done). This ensures, in a multi-monitor
case with mixed scale values, the surface is rescaled correctly to the
actual output it is on if the initial selection of wl->current_output is
incorrect.
Additionally, autofit/geometry values are recalculated if they exist.
This means that dragging a surface across different outputs will autofit
correctly to the new output and not always be "stuck" on the old one.
A very astute observer may notice that set_buffer_scale isn't set when
the surface enters a new output. The API doesn't really indicate this,
but a WAYLAND_DEBUG log reveals that the compositor (well at least
sway/wlroots anyway) magically sets this for you. That's quite fortunate
because setting in the surface handler caused all sorts of problems.

in the original commit, that removed the conditional clearing, an
incorrect assumption was made that clearing "should be practically free"
and can be done always. though, at least on macOS + intel this can have
a performance impact of up to 50% increased usage. it might have an
impact on other platforms and setups as well, but this is unconfirmed.
the reason for removing the conditional clearing was to partially work
around a driver bug on very specific setups, X11 with amdgpu and OpenGL,
to clear garbled frames on start. though it still has issues with
garbled frames in other situation like fullscreening. there is also an
open bug report on the mesa bug tracker about this. setting the
radeonsi_zerovram flag works around all of those issues.
since the flag works around all these issues and the original fix
doesn't work completely we revert it and keep our optimisation.

the screen-name and fs-screen-name option allow for specifying screens
based on their name. this is the name of the NSScreen and also reported

In wayland, setting the surface on a specific monitor only works in
fullscreen so only --fs-screen-name can be implemented. Like with x11,
we prefer --fs-screen over --fs-screen-name if it is set. This may be
more useful than setting by ids because there's no guaranteed order in
which screens are added in wayland. In wayland, the name used here is
the model name detected by the output_listener.

The --screen-name and --fs-screen-name options allow for specifying
screens based on their name. For x11, this is the display name reported
by xrandr. --screen-name and --fs-screen-name mimic the --screen and
--fs-screen options respectively. If --screen is set, then --screen-name
will always do nothing. Likewise, --fs-screen-name does nothing if
--fs-screen is set.

Our canvas size calculation is affected by few factors, and rounded
down more than once - which can result in 0 width or (more typically)
height - e.g. when terminal height is one row.
If the width or height are 0 then all bets are off, so simply skip
the setups and rendering on this case. We can still recover
automatically if the terminal is resized to become bigger.
|
| |
|
|
|
|
|
|

The obvious approach would be SIGWINCH, however, integrating it would
be tricky, so instead we simply poll the size on draw_frame.
This means the image won't resize automatically when still - e.g.
cover art or when paused, though it would re-fit on OSD changes.

For two reasons:
1. It was counter intuitive that there's an "auto" value (which is
actually a libsixel value and not an mpv one), but it's not the
default value - our default was Atkinson.
2. "auto" provides better dithering than Atkinson with libsixel, which
is especially noticeable with smooth gradients - where Atkinson has
visible banding.
In libsixel 1.8.2 the "auto" value maps to Atkinson if the output
palette has up to 16 colors, or to Floyd-Steinberg otherwise (e.g.
using fixed palette with 256 colors chooses Floyd-Steinberg).

The issue was that we only uploaded the palette to the terminal when it
changed (once on init with fixed palette, every frame with dynamic
palette with trheshold=-1, only on scene change with threshold >= 0).
Now we upload it on every frame, and it seems to fix the mlterm image
corruption both with fixed palette and also with dynamic palette with
threshold (i.e. at frames which did not upload a palette).
It's not entirely clear why it's required with mlterm.
It would seem that the palette which libsixel uses with fixed palette
matches the built in default palette in xterm, but not in mlterm.
With dynamic palette we can guess that mlterm resets the palette after a
sixel image, but that's not confirmed.
Uploading the palette on every frame doesn't seem to slow down xterm
when using fixed palette - not clear yet why uploading a different
palette (when using fixedpalette=no) slows it down while same palette
on every frame doesn't.
In mlterm there's no slowdown either way - and now also no corruption.

When mpv is in the background because it was started with
`mpv foo.mp3 &`, or the user did ctrl+z bg, and is then brought to the
foreground with fg, it buffers input until you press enter. This makes
it accept input almost immediately. Having a short interval isn't
important, since input is buffered until the next loop iteration.

Trigraphs such as "??=" (which are enabled by default with -std=c11)

This also drops Python 2 compatibility from file2string, making the
change to the waf rule necessary. The input file is now opened in
binary mode which is also more correct versus the old text mode
which just happened to work even on binary files.

This reverts commit 3d17e19c2c5ca80f916411e7e61126cac8443baa.
The effect of turning off this setting is that mpv doesn't tell libass what
the video stream's resolution is. This happens to result in some files having
their transforms scaled in ways that give higher performance (as described
in #7435) because libass happened to guess a video resolution that resulted
in transforms yielding smaller bitmaps, but it's just as easy for the opposite
to happen depending on the resolutions and effects involved.
The option's name is also somewhat misleading: setting the storage size affects
blur, but it also affects stroke (which is far more important for the vast
majority of scripts) and 3D transforms (which look very screwy when done wrong).

Upstream waf still ships with the default interpreter being "python",
though the script works with both Python 2 and Python 3 (they're not
changing the default choice during 2.0.x releases for compatibility
reasons apparently). Add code to bootstrap.py to change the
interpreter from "python" to "python3" when downloading the "waf"
file.
Running any mpv code under Python 2 should be considered unsupported
in the future (and any code added need not work under Python 2).

Resize the image based on the dimensions reported by
vo_get_src_dst_rects to correctly handle aspect ratio
that might be set/ignored.
Added pad-x and pad-y options for padding.
These options will be used to remove the extra padding.
Some terminals report the padding of 2px in the ioctl
dimensions which can't be used for displaying sixel
output. These options can be used for fine tuning
the output video resolution.
Now all the terminal size detection and calculation logic
is done in a single function at resize. Also top and left
values are computed from the dst_rect parameters to simplify
the logic for the aspect ratio based centering.
Additionally vo-sixel-rows and vo-sixel-cols options
have been added to enable the user to override the values
in case of failures with get_terminal_size2.
This commit also adds ability to handle video zoom correctly.
Whenever video-zoom is triggered, the src and dst rects
will be updated. Scaling seems to work well now.

Previously the mouse command never ended up in enter/leave keypresses
for the default section even when logically required, because input.c
does not know the area of the default section and relies on something
feeding it ENTER/LEAVE presses - which the VO typically does but the
mouse command didn't.
Now the mouse command feeds it ENTER/LEAVE if required.
It's possible to handle it differently and more consistently by:
1. reverting this commit.
2. Updating the default section area whenever the osd dimensions change.
3. Always ignore MOUSE_ENTER keys because the position is not known yet
(but MOSE_MOVE typically follows right away).
4. On mouse move: first generate ENTER/LEAVE if required.
That would guarantee consistency between mouse position and enter/leave
events but could be more sensitive to manage (the default section has
"infinite" area which is used to capture any event outside of specific
section areas), while this commit keeps consistency same as before and
depending on correct external feeding - which we now do better, even if
still not optimally (like before, it's still technically possible that
a script recieves MOUSE_ENTER and then reads the position before it got
updated after the ENTER).

Add a third field: "hover", which is updated from input.c after input
keys MP_KEY_MOUSE_LEAVE and MP_KEY_MOUSE_ENTER - which are typically
sent by the VO.
It's part of mouse-pos and not a new property because it's highly tied
to mouse-pos - it makes x/y invalid while the cursor doesn't hover the
window.
Unike mouse-move, no dummy command was generated, so we add dummy
command in order for observer notification to work even while nothing
is bound.
Like mouse-pos, clients could not detect whether the mouse pointer
hovers the window because the OSC force-binds the MOUSE_LEAVE key, and
now they can using the hover field.
The lua mp.get_mouse_pos() wrapper still returns only x, y because
that's what osc.lua needs. Other clients can simply read the property.
|
| |
|
|
|
|
|
| |
mp.get_mouse_pos() is undocumented and is no longer required - the
property can be used officially by any client now, however, osc.lua
uses it, and also some user scripts learnt to rely on it, so we keep
it - as a trivial wrapper around the new mouse-pos property.

This is a read-only MPV_NODE value with integer fields: x, y.
The values are unmodified from mp_input_get_mouse_pos(...).
Observer notification of this property is tied to the INPUT_PROCESSED
event, which fires after mouse move even if no command is bound
(dummy commands are generated if nothing is bound to ensure that
mp_input_get_mouse_pos returns the latest values - see ac927e39 ).
This allows clients such as JSON IPC to observe mouse position even
while the OSC is enabled - the OSC force-binds mouse move for most
of the window area, making it impossible for other clients to bind
mouse move without breaking the OSC.

Apparently mpv supports loading config files from the same directory as
the mpv.exe. This is a fallback of some sort. It used the old_home
mechanism.
I want to add a warning if old_home exists, but that would always show
the warning on win32. Obviously we don't want that.
Add a separate exe_dir entry to deal with that.
Untested, but probably works.
Mistakenly reverted as part of the default configuration directory
location switch-back in aa18a8e1cde663caeabd93af7d57a745c1a76af6.
Separation of the mpv executable directory from old_path is a
good change now that we warn about the old_config directory also
existing.

This can be viewed at page 4 of the internal stats display (i or I).
CPU time report is the same as at lua.c, but untested - doesn't seem
to work on windows - also not for lua.
TL;DR: Set env MPV_LEAK_REPORT=1 to enable js memory reporting stats.
This also almost doubles the memory usage by js scripts.
For memory reporting, we don't have enough info by default, because
even when using a custom allocator, mujs doesn't report the old size
(on free or realloc) because it doesn't track this value, and as
a result we can't track the overall size.
Our option are either to track the size of each allocation on our own,
or use talloc which tracks this value.
However, using talloc for mujs allocations adds a considerable
overhead, and almost doubles(!) the overall memory used, because each
individual allocation includes a considerable talloc header, and mujs
does many small allocations.
So our solution is that by default we behave like previously - not
using a custom allocator with mujs, and stats does not display memory
usage for js scripts.
However, if the env var MPV_LEAK_REPORT is set to 1, then we use
a custom allocator with talloc and track/report memory usage.
We can't switch allocator at runtime, so an mpv instance either tracks
or doesn't track js scripts memory usage, according to the env var.
(we could use a property and apply it whenever a new script starts,
so that it could change for newly launched scripts, but we don't).

When possible, refer to booleans with "Whether..." since it can refer to
both yes (using input.conf and mp.get_property) and true (using the JSON
IPC or mp.get_property_native/bool), else explicitly say yes/true.
Say "true" for subprocess and osd-overlay named arguments since you
can't use them in input.conf and you will typically use them with the
boolean true in the named arguments, like the subprocess example in the
manpage does (though the string "yes" also works).
Subproperties that can't be accessed with the / syntax like
demuxer-cache-state's bof-cached and eof-cached always return true,
never yes.

this meant input combinations like Shift+MTBN_LEFT did not work. Fix

In the case of the mouse, it is possible that the keyboard may not exist
so be sure to check before trying to get any modifiers. Fixes #8239.

30dcfbc is a workaround for incorrect border sizes that could occur on

Based on the implementation of ffmpeg's sixel backend output written
by Hayaki Saito
https://github.com/saitoha/FFmpeg-SIXEL/blob/sixel/libavdevice/sixel.c
Sixel is a protocol to display graphics in a terminal. This commit
adds support to play videos on a sixel enabled terminal using libsixel.
With --vo=sixel, the output will be in sixel format.
The input frame will be scaled to the user specified resolution
(--vo-sixel-width and --vo-sixel-height) using swscaler and then
encoded using libsixel and output to the terminal. This method
requires high cpu and there are high frame drops for 720p and
higher resolution videos and might require using lesser colors and
have drop in quality. Docs have all the supported options listed
to fine tune the output quality.
TODO: A few parameters of libsixel such as the sixel_encode_policy
and the SIXEL_XTERM16 variables are hardcoded, might want to
expose them as command line options. Also the initialization
resolution is not automatic and if the user doesn't specify the
dimensions, it picks 320x240 as the default resolution which is not
optimal. So need to automatically pick the best fit resolution for
the current open terminal window size.

This allows keybindings such as:
a script-message-to console type "seek :0 absolute" 6
% script-message-to console type "seek absolute-percent" 6
The cursor position 0 isn't allowed because it has the weird effect of
filling the console with the text twice, leaving the cursor in the
middle.
Negative positions would put the cursor n characters before the end, and
positions greater than the text's length at the end. They seem to work
at first, but the console breaks when you move the cursor, so they
aren't allowed.
It seems that float values don't cause issues, but I'm using the
argument's floor anyway to be safe. Using >= 1 instead of > 0 ignores
values like 0.5.

The wl_pointer interface defines button argument as “a button code as
defined in the Linux kernel's linux/input-event-codes.h header file,
e.g. BTN_LEFT.”
We could #define these few buttons ourselves, but there is no system to
test it on, so for now let’s disable Wayland support on them.
This is a call to non-Linux system maintainers, please help test this
backend on your system and report issues you find, or even working
state.

Wayland’s wl_pointer interface describes the button event’s argument as

This introduces the delete-watch-later-config command, to complement
write-watch-later-config. This is an alternative to #8141.
The general problem that this change is attempting to help solve has
been described in #336, #3169 and #6574. Though persistent playback
position of a single file is generally a solved problem, this is not
the case for playlists, as described in #8138.
The motivation is facilitating intermittent playback of very large
playlists, consisting of hundreds of entries each many hours
long. Though the current "watch later" mechanism works well - provided
that the files each occur only once in that playlist, and are played
only via that playlist - the biggest issue is that the position is
lost completely should mpv exit uncleanly (e.g. due to a power
failure). Existing workarounds (in the form of Lua scripts which call
write-watch-later-config periodically) fail in the playlist case, due
to the mechanism used by mpv to determine where within a playlist to
resume playback from.
The missing puzzle piece needed to allow scripts to implement a
complete solution to this problem is simply a way to clean up the
watch-later configuration that the script asked mpv to write using
write-watch-later-config. With that in place, scripts can then
register an end-file event listener, check the stop playback reason,
and in the "eof" and "stop" case, invoke delete-watch-later-config to
delete any saved positions written by write-watch-later-config. The
script can then proceed to immediately write a new one when the next
file is loaded, which altogether allows mpv to resume from the correct
playlist and file position upon next startup.
Because events are delivered and executed asynchronously,
delete-watch-later-config takes an optional filename argument, to
allow scripts to clear watch-later configuration for files after mpv
had already moved on from playing them and proceeded to another file.
A Lua script which makes use of this change can be found here:
https://gist.github.com/CyberShadow/2f71a97fb85ed42146f6d9f522bc34ef
(A modification of the one written by @Hakkin, in that this one takes
advantage of the new command, and also saves the state immediately
when a new file is loaded.)

Testing kwinft out (kwin fork), it was discovered that sometimes it
would return a ust value of 0 which subsequently resulted in incorrect
presentation statistics (i.e. large negative numbers which are obviously
impossible). Arguably, it shouldn't return 0s, but a workaround for mpv
in this case is harmless.

7fb972f fixed transparency on x11/EGL/Mesa but happened to also break it
for wayland and nvidia. Ideally on wayland, you should just be able to
pick the right EGLConfig that has alpha but this doesn't seem to work
because reasons. So just go back to setting the EGL_ALPHA_SIZE bit if
the user asks for alpha. Apparently this worked before for nvidia as
well. The hack is to just run an eglQueryString in the x11egl context.
If it picks up Mesa as the EGL_VENDOR, then force ctx->opts.want_alpha
to 0 and let pick_xrgba_config take care of the rest.

Made possible with 00b9c81. 34b8adc let the wayland surface set an
opaque region depending on if alpha was set by the user or not. However,
there was no attempted detection for runtime changes and it is possible
(at least in wayland vulkan) to toggle the alpha on and off. So this
meant, we could be incorrectly signalling an opaque region if the user
happened to change the alpha. Additionally, add a helper function for
this and use it everywhere we want to set the opaque region.

vo_gpu has a small set of options for ra_ctx that can be set. In
practice, runtime toggling doesn't matter for most of these as they have
no effect while a video is playing. However, changing the alpha option
during runtime can actually work depending on the backend used. mpv
already detected when one of these options changed, but it made no
attempt to update the options in the ra_ctx accordingly (likely because
nothing made any use of this information). Another related change is to
add an update_render_opts to the fns and allow invidiual backends to
(optionally) use it.

efb0c5c changed the rendering logic of mpv on wayland and made it skip
rendering when it did not receive frame callback in time. The idea was
to skip rendering when the surface was hidden and be less wasteful. This
unfortunately had issues in certain instances where a frame callback
could be missed (but the window was still in view) due to imprecise
rendering (like the default audio video-sync mode). This would lead to
the video appearing to stutter since mpv would skip rendering in those
cases.
To account for this case, simply re-add an old heuristic for detecting
if a window is hidden or not since the goal is to simply not render when
a window is hidden. If the wait on the frame callback times out enough
times in a row, then we consider the window hidden and thus begin to
skip rendering then. The actual threshold to consider a surface as
hidden is completely arbitrary (greater than your monitor's refresh
rate), but it's safe enough since realistically you're not going to miss
60+ frame callbacks in a row unless the surface actually is hidden.
Fixes #8169.

As per the client API, a client can connect to any arbitrary wayland
socket. mpv has always just passed NULL which connected to the
compositor currently in use, but one could just as easily pass the name
of a different socket (i.e. the value of WAYLAND_DISPLAY). Here, we just
expose this argument as a user configurable option. If the user passes a
socket name that does not exist, then print a warning and fall back to
NULL.

Apparently a part of the wayland spec. A compositor may use a surface
that has set part of itself as opaque for various optimizations. For
mpv, we simply set the entire surface as opaque as long as the user has
not set alpha=yes (note: alpha is technically broken in the wayland EGL
backend at the time of this commit but oh well). wlshm is always opaque.

Picks up files like "cover.jpg". It's made part of normal external file
loading, so I'm adding 3 new options that are direct equivalents for the
options that control loading of external subtitle and audio files. Even
though I bet nobody wants them and they just increase confusion... I
guess the world is actually hell, so this outcome should be fine.
It prefers non-specific external files like "cover.jpg" over embedded
cover art. Not sure if that's wanted or unwanted.
There's some pain over explicitly marking such files as external
pictures. This is basically an optimization: in most cases, a heuristic
would treat an image file loaded with --external-file the same (it's a
heuristic because ffmpeg can't tell us whether something is an image or
a video). However, even with this heuristic, it would decode the cover
art picture again on each seek, which would essentially slow down
seeking in audio files. This bothered me greatly, which is why I'm
adding these additional options at all, and bothered with the previous
commit.

Back in the olden days, mpv's wayland backend was driven by the frame
callback. This had several issues and was removed in favor of the
current approach which allowed some advanced features (like
display-resample and presentation time) to actually work properly.
However as a consequence, it meant that mpv always rendered, even if the
surface was hidden. Wayland people consider this "wasteful" (and well
they aren't wrong). This commit aims to avoid wasteful rendering by
doing some additional checks in the swapchain. There's three main parts
to this.
1. Wayland EGL now uses an external swapchain (like the drm context).
Before we start a new frame, we check to see if we are waiting on a
callback from the compositor. If there is no wait, then go ahead and
proceed to render the frame, swap buffers, and then initiate
vo_wayland_wait_frame to poll (with a timeout) for the next potential
callback. If we are still waiting on callback from the compositor when
starting a new frame, then we simple skip rendering it entirely until
the surface comes back into view.
2. Wayland on vulkan has essentially the same approach although the
details are a little different. The ra_vk_ctx does not have support for
an external swapchain and although such a mechanism could theoretically
be added, it doesn't make much sense with libplacebo. Instead,
start_frame was added as a param and used to check for callback.
3. For wlshm, it's simply a matter of adding frame callback to it,
leveraging vo_wayland_wait_frame, and using the frame callback value to
whether or not to draw the image.

In the recent terminal commit, I "compressed" the read() error handling,
and messed it up. The return value could be -1 for other non-fatal
errors (such as EIO when trying to read while backgrounded), which
resulted in buf.len getting messed up.

Due to Unix being legacy garbage, it's not possible to safely detect the
ESC key on terminal. The key sequences are ambiguous. The code for the
ESC key also starts the sequences for other special keys.
Until now, you needed to hit ESC twice for it to be recognized.
Attempt to handle this better by using a timeout to detect the key. If
ESC is in the input buffer, but nothing else arrived after a timeout,
assume it's the ESC key. I think this is the method vim uses. Currently,
the timeout is set at 100ms. This is hardcoded and cannot be changed.
It's possible that this causes problems on slow ssh connections or so.
I'm not sure what exactly happens if you manage to get ESC + another
normal key into the input buffer. If it's a known sequence, it will be
matched and interpreted as such. If not, it'll probably be discarded.

Previous commit fixes it for libswscale. The libzimg path has extra code
to copy by slice, but it still may access pixel groups using normal
memory accesses (for example, reading rgba pixel data via uint32_t), so
document a minimum alignment requirement per pixel format.

If the alignment is less than 16, certain libswscale code paths will
silently corrupt memory outside of the target buffer. This actually
affected the libmpv software rendering API (that was fun to debug).
Rather than passing this problem to the next API user, try to avoid it
within libmpv.
It's unclear which alignment libswscale requires for safe operation. I'm
picking 32 (one more than the observed safe value in the case I
experienced), because libavfilter mostly uses this value.
The way to work this around is slow: just make a full copy of the entire
input or output image. Possibly this could be optimized by using the
slice API, but that would be more effort, and would likely expose
further libswscale bugs. Hope that this is a rarely needed path.
The next commit will update the alignment requirement documentation
bits.

Pause can be changed during a file change, such as with for example
--reset-on-next-file=pause, or in hooks, or by being quick, and in this
case the AO's pause state was not updated correctly. mpctx->ao_chain is
only set if playback is fully initialized, while the AO itself in
mpctx->ao can be reused across files.
Fix this by always running set_pause_state() if the pause option is
changed. Could cause new bugs since running this used to be explicitly
avoided outside of the loaded state. The handling of time_frame is
potentially worrisome.
Regression due to recent audio refactor; before that, the AO didn't have
a separate/persistent pause state.

Since b74c09efbf7, audio-only files let you seek to arbitrary points
beyond the end of the file (but still displayed the time clamped to the
nominal file duration). This was confusing and just not wanted. The
reason is probably that the commit removed setting the audio PTS for
data before the seek target, so if you seek past the end of the file,
the audio PTS is never set. This in turn means the logic to determine
the current playback time has no PTS at all, and thus falls back to the
seek PTS.
This happened in the past for other reasons (like efe43d768f). I have
enough of this, so I'm just changing the code to clamp the seek
timestamp to a "known" range. Do this when seeking ends, because in the
fallback case, the playback time shouldn't be stuck at e.g. "end +
seek_argument". Also do it when initiating a new seek (mp_seek), because
if the previous seek hasn't finished yet, it shouldn't add them up and
allow it to go "out of range" either. The latter is especially relevant
for hr-seeks.
Doing this clamping is problematic because the duration is a possibly
invalid value from the demuxer, or just missing. Especially with
timestamp resets, fun sometimes happens, and in these situations it
might be better not to clamp.
One could argue you should just use the last audio timestamp returned by
the decoder or demuxer (even if that directly conflicts with --end), but
that sounds even more hairy.
In summary: what a dumb waste of time, what the fuck.

Add a property that returns whether the window is focused, currently
only for X11 and Wayland.
My use cause for this is having an equivalent of pause-when-minimize.lua
for tiling window managers: make mpv play only while it's in the current
workspace or is focused (I'm fine with either one but prefer focus).
On X I do this by observing display-names, which is empty when the
rectangles of the display and mpv don't intersect, but on Wayland its
value doesn't change when mpv leaves the current workspace (and the same
check doesn't work since the geometries still intersect).
This could later be made writable as requested in #6252.
Note that on Wayland se shouldn't consider an unactivated window with
keyboard input focused.
The wlroots compositors I tested set activated after changing the
keyboard focus, so if you set wl->focused only in
keyboard_handle_enter() and keyboard_handle_leave() to avoid adding the
"has_keyboard_input" member, focused isn't set to true when first
opening mpv until you focus another window and focus mpv again.
Conversely, if that order can't be assumed for all compositors, we
should toggle wl->focused when necessary in keyboard_handle_enter() and
keyboard_handle_leave() as well as in handle_toplevel_config().

--audio-stream-silence is a shitty feature compensating for awful
consumer garbage, that mutes PCM at first to check whether it's
compressed audio, using formats advocated and owned by malicious patent
troll companies (who spend more money on their lawyers than paying any
technicians), wrapped in a wasteful way to make it constant bitrate
using a standard whose text is not freely available, and only rude users
want it. This feature has been carelessly broken, because it's
complicated and stupid. What would Jesus do? If not getting an aneurysm,
or pushing over tables with expensive A/V receivers on top of them, he'd
probably fix the feature. So let's take inspiration from Jesus Christ
himself, and do something as dumb as wasting some of our limited
lifetime on this incredibly stupid fucking shit.
This is tricky, because state changes like end-of-audio are supposed to
be driven by the AO driver, while playing silence precludes this. But it
seems code paths for "untimed" AOs can be reused.
But there are still problems. For example, underruns will just happen
normally (and stop audio streaming), because we don't have a separate
heuristic to check whether the buffer is "low enough" (as a consequence
of a network stall, but before the audio output itself underruns).

The render API replaced the opengl_cb API over 2 years ago. Since then,
the opengl_cb API was emulated on top of the render API. While it would
probably be reasonable to emulate these APIs until they're removed in an
eventual libmpv 2.0 bump, I have some non-technical reasons to disable
the API now.
The API stubs remain; they're needed for formal ABI compatibility.

If you encode to e.g. an audio-only format, then video is disabled
automatically. This also takes care of the very cryptic error message.
It says "[vo/lavc] codec for video not found". Sort of true, but
obscures the real problem if it's e.g. an audio-only format.
|

I don't see the point of this. Not doing it may defer an error to later.
That's OK? For now, it seems better to reduce the encoding internal API.

in a different way.

AVFrame doesn't have public code for pool allocation, so mpv does it
manually. AVFrame allocation is very tricky, so we added a bug.
This crashed with libopus encoding, but not some other audio codecs,
because the libopus libavcodec wrapper accesses AVFrame.data. Most code
tries to avoid accessing AVFrame.data and uses AVFrame.extended_data,
because using the former would subtly corrupt memory on more than 8
channels. The fact that this problem manifested only now shows that most
AVFrame consuming FFmpeg code indeed uses extended_data for audio.

It is now the AO's responsibility to handle period size alignment. The
ao->period_size alignment field is unused as of the recent audio
refactor commit. Remove it.
It turns out that ao_alsa shows extremely inefficient behavior as a
consequence of the removal of period size aligned writes in the
mentioned refactor commit. This is because it could get into a state
where it repeatedly wrote single samples (as small as 1 sample), and
starved the rest of the player as a consequence. Too bad. Explicitly
align the size in ao_alsa. Other AOs, which need this, should do the
same.
One reason why it broke so badly with ao_alsa was that it retried the
write() even if all reported space could be written. So stop doing that
too. Retry the write only if we somehow wrote less.
I'm not sure about ao_pulse.

This replaces the two buffers (ao_chain.ao_buffer in the core, and
buffer_state.buffers in the AO) with a single queue. Instead of having a
byte based buffer, the queue is simply a list of audio frames, as output
by the decoder. This should make dataflow simpler and reduce copying.
It also attempts to simplify fill_audio_out_buffers(), the function I
always hated most, because it's full of subtle and buggy logic.
Unfortunately, I got assaulted by corner cases, dumb features (attempt
at seamless looping, really?), and other crap, so it got pretty
complicated again. fill_audio_out_buffers() is still full of subtle and
buggy logic. Maybe it got worse. On the other hand, maybe there really
is some progress. Who knows.
Originally, the data flow parts was meant to be in f_output_chain, but
due to tricky interactions with the playloop code, it's now in the dummy
filter in audio.c.
At least this improves the way the audio PTS is passed to the encoder in
encoding mode. Now it attempts to pass frames directly, along with the
pts, which should minimize timestamp problems. But to be honest, encoder
mode is one big kludge that shouldn't exist in this way.
This commit should be considered pre-alpha code. There are lots of bugs
still hiding.

Do not make resetting the "access" filters reset the queue itself. This
is more flexible, and will be used in a later commit.
Also, if the queue is not in the reset state while the input access
filter is reset, make it immediately request data again. This is more
consistent, because it'll enter the state it "should" be, rather when
the filter's process function is called at an (essentially) random point
in the future. This means the filter graph will resume work on its own
if the queue was not reset before filter reset.
This could affect the only current user of f_async_queue, the code for
the --vd-queue-enable/--ad-queue-enable feature in f_decoder_wrapper.
But it looks like this already uses it in a compatible way.

This is a kind of bad hack (with bad implementation) to paint over other

Transparent windows on X11/EGL/native Mesa GL didn't work for various
reasons. From what I remember, the current code did work with nvidia at
least. Mesa has made attempts to fix this, but they never really made it
in.
But it turns out you can make EGL/Mesa list the EGLConfigs that use X11
RGBA visuals, and context_x11egl.c contains code that explicitly selects
them if alpha is requested (see pick_xrgba_config()).
The reason EGL/Mesa did not list them (and thus breaking transparency)
is because we requested a EGL_ALPHA_SIZE != 0 if alpha is requested. But
the transparent EGLConfigs use EGL_ALPHA_SIZE == 0. That's because EGL
doesn't actually support the concept of transparent windows; the alpha
size parameter is something else (memory rendering without FBOs or
something, I don't care enough to look up the real reasons).
This still won't work on Wayland. Every EGL backend needs platform
specific code. (Good job, EGL, such an awesome platform independent
standard.)

Oversight in b0f0be7. The user_sbc value would update but not last_sbc
if no presentation events were received. This would result in an
incorrect sbc_passed value (in practice, this should always be 1 since,
as far I know, all wayland compositors are currently only capable of
double buffering). When bring the window back into view, it would result
in a single frame of very high vsync jitter. Although in most cases it
was imperceptible, rarely I was able to completely break playback (i.e.
constant mistimed/dropped frames). Fix this by simply incrementing
last_sbc by 1 if the window is hidden. The buffer swap call did still
occur. The user just didn't see it.

This reverts commit 41243e7c4f98b410195397b6758f9796acd9de57.
This fixes image format detection. FFmpeg has an utter called "image2",
which is designed to read patterns in filenames (so you can play
something like "%*.jpg" for all jpg files in the current directory).
"image2" is not what we want; it's just broken with custom I/O like
mpv uses it, and we don't want to "accidentally" interpret filenames
as pattern. That's why mpv blacklists it.
Unfortunately, "image2" is sometimes the format that FFmpeg's probe API
returns as best match. Thus demux_lavf fails to detect the file type,
and after some more futile attempts, we end up at demux_mf, which uses
detection by file extension. (Not sure why. I guess MPlayer did that,
and foudn that sufficient.) If the file extension is wrong (which
happens a lot because apparently the world is full of idiots who don't
manage to get the most simple things right), the image "loads", but
decoding obviously fails.
There's no easy way around this. The FFmpeg API has no mechanism to
exclude a specific format from probing (like image2, which breaks stuff
for us). Out of the 5 probe functions the API provides, none can probe
a specific format or include or exclude specific formats. The main
problem is that AVInputFormat.read_probe is a private symbol.
FFmpeg itself has no problem opening such files. It turns out that it
works, because even though image2 by itself uses detection by file
extension, it uses private API to further probe the exact format. It
explicitly excludes itself to prevent recursion.
But fortunately, that also means that it's impossible to get the image2
format if no filename is passed to the prober. (No filename, no file
extension.) Apparently we pass it in because it helps in corner cases.
Until almost 3 years ago, we passed the filename only when normal
probing already failed. Restore this by this revert. It makes
incorrectly named files work. The revert also makes the (apparently
forgotten) comment above the touched line of code true again.
Yes, quite possible that this breaks some mp3s again. You can't win
with FFmpeg. Thanks FFmpeg for making us fail at opening simple image
files and/or the most widely used file format for audio.

Why on earth did I ever bother with this dumb crap? If we do not have
any presentation statistics, just set the relevant vo_sync_info values
to -1 to disable it. It's much simpler than using mp deltas and trying
to keep up with mpv's clock. This also appears to fix audio/video
desynchronization if you start a video with the pause flag, move it out
of view, and then unpause it. Technically harmless since the video
wasn't even in view and putting back in view recovered it, but a quieter
terminal is better.

Well, whatever. Only results in an error message being printed, because

This can happen if a file contains headers only, or if decoding of all
data failed, and such. Interestingly, it also happened when doing "mpv
--loop emptyfile.png", because demux_mf still detects file formats by
file extension.
In this situation, the player burned a lot of CPU by restarting playback
after doing nothing. Although such "degenerate" behavior can't be
avoided in all situations (what if you loop a file with 1 audio
sample?), detecting this seems to make sense.
For now, this actually decrements the loop count by 1, and then errors
out with a warning. Works for --loop and --ab-loop, while
--loop-playlist already avoids this situation with an existing
mechanism.

Accepting ":" in addition to "," seems confusing and dumb. It only
causing problems when you want to pass a value that contains ":". Remove
support for ":", it is now treated like any other normal character. This
affects all options that are listed as "Key/value list" in the option
list.
It's possible that this breaks for someone who happened to use ":" as
separator. But this was undocumented, and never recommended. Originally,
the option treated many other characters in a special way, but this was
changed in commit a3d561f950e74fe. I'm, not sure why ":" was explicitly
included. Maybe because -the absurd -vf/--af syntax uses ":" as list
separator. But "," was always recommended and used in examples for
key/value options.

move all backend independent code parts in their own folder and files,
to simplify adding new backends. the goal is to only extend one class
and add the backend dependent parts there. usually only the (un)init,
config and related parts need to be implemented per backend. furthermore
all needed windowing and related events are propagated and can be
overwritten. the other backend dependent part is usually the surface for
rendering, for example the opengl oder metal layer.
in the best case a new backend can be added with only a few hundred
lines.

The software rendering API makes libswscale directly write into supplied

It was possible for sway to get incorrectly sized borders if you resized
the mpv window in a creative manner (e.g. open a video in a non-floating
mode, set window scale to 2, then float it and witness wrong border
sizes). This is possibly a sway bug (Plasma doesn't have these border
issues at least), but there's a reasonable workaround for this.
The reason for the incorrect border size is because it is possible for
mpv to ignore the width/height from the toplevel listener and set its
own size. This new size can differ from what sway/wlroots believes the
size is which is what causes the sever side decorations to be drawn on
incorrect dimensions.
A simple trick is to just explicitly commit the surface after a resize
is performed. This is only done if mpv is not fullscreened or maximized
since we always obey the compositor widths/heights in those cases.
Sending the commit signals the compositor of the new change in the
surface and thus sway/wlroots updates its internal coordinates
appropriately and borders are no longer broken.

This allows users to control whether full dialogue subtitles are displayed
with an audio track already in their preferred subtitle language.
Additionally, this improves handling for the forced flag, automatically
selecting between forced and unforced subtitle streams based on the user's
settings and the selected audio.

The original goal was to simplify all this logic to make it less fragile
and breaky. Unfortunately, that didn't exactly happen and things might
actually be more complicated in some ways (well in other ways it's
simplier). There's a lot of negotiation back and forth between the
client and the compositor regarding sizes. The client (aka mpv) can do a
resize on its own. But also the compositor can request its own resize
(which we should be nice and listen to of course). The older method had
a lot of breakfalls/edgecases that were gradually patched up as time
went on, but that approach is really fragile. This refactor should,
hopefully, be on a more solid foundation.
Don't call any of the xdg toplevel state changing functions
(fullscreen, maximized, etc.) directly. Use the toggle wrapper
functions. These signal that the state was changed which is later
handled in the toplevel listener.
Introduce a new vdparams variable that stores the actual dimensions of
the video. This does create some new (but neccesary) complexity.
wl->vdparams stores what the actual dimensions of the video are
(according to mpv). wl->window_size stores the last size of the window
(so it includes any manual resizes for instance). wl->geometry is the
actual size of the output that gets displayed on the screen.

Add support for reading a byte range from a stream via
the `slice://` protocol.
Syntax is `slice://start[-end]@URL` where end is a maximum
(read until end or eof).
Size suffixes support in `m_option` is reused so they can
be used with start/end.
This can be very useful with e.g. large MPEGTS streams with
corruption or time-stamp jumps or other issues in them.

We've had some serious issues with GNOME in the past, but since then
their compositor has undergone some major internal improvements. The
most severe one [1], random vsync spikes and mistimed frames, can no
longer be reproduced by the original author of the issue. There are some
minor UI-related things (lack of window decorations for instance since
there is no xdg-decoration support), but users don't seem to complain
about that too much and they aren't revelant to playback.
3.38 isn't out quite yet, but that should also fix playback issues when
on a multimonitor setup (the fix is in the master branch at the moment).
In terms of playback, the only real concerning issue is the lack of idle
inhibit so a warning is still displayed. But GNOME has their own
workaround that users can use for that so if anyone happens to complain,
we can just point them to that.

When using presentation time, we have to be sure to update the ust when
no presentation events are received to make sure playback is still
smooth and in sync. Part of the recent presentation time refactor was to
use the presentation discarded event to signal that the window is
hidden. Evidently, this doesn't work the same everywhere for whatever
reason (drivers?? hardware??) and at least one user experienced issues
with playback getting out of sync since (presumably) the discarded event
didn't occur when hiding the window. Instead, let's just go back to the
old way of checking if the last_ust is equal to the ust value of the
last member in the wayland sync queue. Fixes #8010.

The motivation for this change was a segfault caused by e107342 which
has complicated reasons for occuring (i.e. I'm not 100% sure but I think
it is a really weird race). The major part of this commit is moving the
initialization of presentation listener to the frame_callback function.
Calling it in swap_buffers worked fine but in practice it meant a lot of
meaningless function calls if a window was hidden (the presentation
would just be immediately discarded). By calling it in frame_callback,
we ensure the listener is only created when it is possible to receive a
presentation event.
Of course calling the presentation listener in feedback_presented or
feedback_discarded was considered, but ultimately these events are too
slow. Receiving the ust/msc/sbc triplet here and then passing it to mpv
results in higher vsync judder since there is (likely) not enough time
before the next pageflip. By design, the frame callback is meant to give
us as much time as possible before the next repaint so calling it here
is probably optimal.
Additionally, we can make better use of the feedback_discarded event.
The wp_presentation_feedback should not be destroyed here. It will be
taken care of either when we get feedback again or when the player
quits. Instead what we can do is set a bool that tells wayland_sync_swap
to update itself based on mp_time delta. In practice, the result is not
any different than before, but it should be more understandable what is
going on now.
Of course, the segfault mentioned at the beginning is fixed with this as
well.

lua/js utils.get_env_list() uses `environ' which was ANSI, thus
it broke any unicode names/values.
mpv already has an internal utf8_environ for win32, but it's used
only at the getenv(..) wrapper and not exposed in itself, and also it
has lazy initialization - on first getenv() call.
Now `environ' maps to a function which ensures initialization while
keeping it an l-value (like posix expects).
The cost of this fuglyness is that files should include osdep/io.h
(which now declares environ as extern) rather than declaring it
themselves, or else the build will break on mingw.

This was a vague idea how to handle passing byte arrays from Lua to the
mpv command interface in a somewhat reasonable way. The idea was
cancelled, but leave the Lua part of it, since it might get useful
later, and prevents passing (and silently cutting off) such byte
strings.
Barely tested, let's say not tested at all.

Make it possible to feed a string to stdin of a subprocess. Out of
laziness, it can't be an arbitrary byte string. (Would require adding an
option type that takes in a Lua byte string.)
Do not set stdin of a subprocess to fd 0 (i.e. mpv's stdin) anymore,
because it makes things more consistent. Enabling stdin didn't make too
much sense in the first place, so this behavior change seems
justifiable.
win32 support missing.

Just some small changes when creating the xdg_surface. Don't set the
toplevel title (or app id) in create_xdg_surface anymore because it's
entirely pointless. Also make it possible for create_xdg_surface to
return something other than 0 so the error checking is somewhat
meaningful. It's not really clear if these xdg functions can even fail
in the first place (perhaps some weird proxy marshalling crap could
possibly go wrong somehow), but it can't hurt. Note that all app id
stuff has been removed (temporarily) in this commit. See the next commit
which adds it back in.

Seems like this is requested all the time.
It seems libass allows out of range values, but does allows the subtitle
to go out of the screen at the bottom (only when moving it to the top
it's "clamped"). Too bad, don't do that then. The bitmap sub rendering
code on the other hand is under our control, and will not move a
subtitle out of the screen.

Options like --sub-ass-force-style and others could not be changed at
runtime (the changes didn't take any effect). Fix this by using the
brutal approach, and completely reinit the subtitle state when this
happens. Maybe a bit clunky, but for now I'd rather not put more effort
into this.

This sets the activeCodePage property in the manifest, which forces the
ANSI code page to be UTF-8 in Windows 10 1903 and up. It shouldn't make
a difference for mpv itself, since mpv already uses the wide-char APIs
for most functions, however some of mpv's dependencies, such as Lua,
rely on the ANSI codepage. Hence this change enables support for Unicode
file names in Lua's I/O library.
Thanks @avih for finding this property.

Uses the mechanism introduced in the previous commit. The hope was to

Make it possible to restore from profiles by backing up the option
values before profile application. This is sort of like unapplying a
profile. Since there might be multiple ways to do this, a profile needs
to explicitly provide the "profile-restore" option, which specifies how
exactly this should be done.
This is a big mess. There is not natural way to do this. Profile
application is "destructive" and simply changes the values of the
options. Maybe one could argue that the option system should have
hierarchical "overlays" of profiles instead, where unset options will
use the value of the lower profiles. Options set interactively by the
user would be the top profile. Default values would be in the lowest
profile. You could unapply a profile by simply removing it from this
overlay stack.
But uh, let's not, so here's something stupid. It reuses some code used
for file local options to reduce code size. At least the overlay idea
would still be possible in theory, and could be added as another
profile-restore mode.
This is used by the following commit.

The callback now gets an object argument with defer/cont functions.
Like the lua code, the behavior is that each hook event allows at
most one continue, but nothing enforces the order of continuations
if more hook events arrive before prior ones were continued - which
is possible now with the defer option, but wasn't possible before
(continuation was synchronous from the hook event handler).

The property observation mechanism is fairly asynchronous to the player
core, and Lua scripts also are (they run in a separate thread). This may
sometimes lead to profiles being applied when it's too load.
For example, you may want to change network options depending on the
input URL - but most of these options would have to be set before the
HTTP access is made. But it could happen that the profile, and thus the
option, was applied at an slightly but arbitrary later time.
This is generally not fixable. But for the most important use-cases,
such as applying changes before media opening or playback
initialization, we can use some of the defined hooks.
Hooks make it synchronous again, by allowing API users (such as scripts)
to block the core because it continues with loading.
For this we simply don't continue a given hook, until we receive an idle
event, and have applied all changes. The idle event is in general used
to wait for property change notifications to settle down. Some of this
relies on the subtle ways guarantees are (maybe) given. See commit
ba70b150fbe for the messy details. I'm not quite sure whether it
actually works, because I can't be bothered to read and understand my
bullshit from half a year ago. Should provide at least some improvement,
though.
|
| |
|
|
|
|
|
| |
This can now opt to not continue a hook after the hook callback returns.
This makes it easier for scripts, and may make it unnecessary to run
reentrant event loops etc. for scripts that want to wait before
continuing while still running the event loop.

This is taken from a somewhat older proof-of-concept script. The basic
idea, and most of the implementation, is still the same. The way the
profiles are actually defined changed.
I still feel bad about this being a Lua script, and running user
expressions as Lua code in a vaguely defined environment, but I guess as
far as balance of effort/maintenance/results goes, this is fine.
It's a bit bloated (the Lua scripting state is at least 150KB or so in
total), so in order to enable this by default, I decided it should
unload itself by default if no auto-profiles are used. (And currently,
it does not actually rescan the profile list if a new config file is
loaded some time later, so the script would do nothing anyway if no auto
profiles were defined.)
This still requires defining inverse profiles for "unapplying" a
profile. Also this is still somewhat racy. Both will probably be
alleviated to some degree in the future.

Sway 1.5 started sending more pointer motion events to mpv which broke
the autohiding behavior. The cursor would appear again if you
fullscreened. Sway had a good reason to do this because certain
applications had inconsistencies between hardware cursor and software
cursor without rebasing on state changes[1]. So mpv needs to take this
special case into consideration.
Initially, simply checking mouse coordinates for changes was considered,
but this doesn't work. All coordinates are surface-local in wayland so
something can appear to move in the local coordinate space but not
globally. You're not allowed to know global mouse coordinates in
wayland, and we don't care about local coordinate changes in mpv so this
approach isn't viable.
Instead, let's just keep track of a local state change. If the toplevel
surface changes in some way (fullscreen, maximized, etc.), then just set
a bool that lets us ignore the mp_input_set_mouse_pos function. This
keeps the cursor from appearing simply because the state was changed
(i.e. fullscreening). For compositors that don't send pointer motion
events on a state change, this does technically mean that the initial
mp_input_set_mouse_pos is never set. In practice, this isn't a
noticeable difference though because moving a mouse generates a ton of
motion events so you'll immediately see it on the second motion event.

wl_display_dispatch is dangerous because it will block forever if the
event queue is empty. Any direct calls to this function should just be
replaced with wl_display_dispatch_pending which accomplishes the same
thing for mpv's purposes without any chance of blocking.
The other potential trap is wl_display_roundtrip. It can internally call
wl_display_dispatch which in certain circumstances could potentially
block. There are cases where we need the server to finish processing
client requests before doing anything else so this can not be cleanly
avoided. The dangerous call is the usage of wl_display_roundtrip in
vo_wayland_wait_frame. In the majority of cases, this shouldn't be a
problem because the previous wl_display_read_events should always queue
up some events on the fd for wl_display_roundtrip to send. However, the
compositor could potentially send us an error in the display queue that
could lead to bad behavior when wl_display_roundtrip is called.
The wl_display_roundtrip can't be removed because we are relying on its
semi-blocking capabilities, but the logic can be slightly adjusted to be
safer. The obvious thing to do is to make sure we check the pollfd for
any errors. If one is returned, then we call wl_display_cancel_read and
try again. The less obvious trick is to call wl_display_dispatch_pending
and move wl_display_roundtrip outside of the blocking + timeout loop.
This change has some subtle but important differences. Previously,
vo_wayland_wait_frame would read an event and wait on the server to
process it one-by-one. With this change, the events are dispatched as
soon as possible to the server and then we wait on all of those
(potentially multiple) events to be processed after we have either
received frame callback or the loop times out.
After that is done, we can then check for if there are any errors on the
display. If it's all clear, we can run wl_display_roundtrip without any
worries. If some error happens, then don't execute the function at all.

the problem here is that with time, and because the macOS VMs don't get
updated, the homebrew update is getting longer since more and more
changes have to be pulled. to prevent that, we cache the homebrew
installation folder after the update. that way we don't have to update
several months worth of updates every build. for the legacy build we
have to check put master again to actually cache the newest homebrew
version.
additionally to that, we also do the same as on the legacy build, with
the addition of not removing all installed formulas but only the ones
we don't need. so we don't need to reinstall those.

just remove all pre installed formulas, since we don't need the majority
of it. after that install what we need. this also fixes the brew update
of those formulas where the source links were broken like popt.
this also helps when the build times out due to building some formulas
from source that are not dependencies we need.

Previously, the compositor was signaled that a drag-and-drop ended with
wl_data_offer_finish in check_dnd_fd. This is, however, erroneous
because it is outside of the data_device_listener and in some cases
caused errors with certain compositors. check_dnd_fd itself does not
need to know or care about anything that happens in wayland. It just
needs to read data from an fd. The simple fix is to just always signal
the end of a drag-and-drop in data_device_handle_drop. check_dnd_fd can
free memory and close the fd later, but it should not talk to the
compositor. Fixes #7954.

The read of the wayland display fd in vo_wayland_wait_events was
incorrect and technically vulnerable to race conditions. The correct
usage as per the client api is to use wl_display_prepare_read as well as
wl_display_read_events.

This fixes the "run" and "subprocess" commands on Windows, including
youtube-dl support.
Unix-like FD inheritance is emulated on Windows by using an undocumented
data structure[1] that gets passed to the newly created process in
STARTUPINFO.lpReserved2. It consists of two sparse arrays listing the
HANDLE and internal CRT flags corresponding to each FD. This structure
is used and understood primarily by MSVCRT, but there are other runtimes
and frameworks that can write it, like libuv.
The code for creating asynchronous "anonymous" pipes in Windows has been
enhanced and moved into windows_utils.c. This is mainly an artifact of
an unfinished future change to support anonymous IPC clients in Windows.
Right now, it's still only used in subprocess-win.c

Sharing a process sure is hard in POSIX.
The rationale is that you'd have to handle EINTR on every single
blocking syscall. stream_file.c does not seem to handle it on read()
calls.
It appears that on most modern systems, this can happen only if you call
sigaction(), and incompetently forget to add SA_RESTART. signal()
usually adds it.

Add env and detach arguments. This means the command.c code must use the
"new" mp_subprocess2(). So also take this as an opportunity to clean up.
win32 support gets broken by it, because it never made the switch to the
newer function.
The new detach parameter makes the "run" command fully redundant, but I
guess we'll keep it for simplicity. But change its implementation to use
mp_subprocess2() (couldn't do this earlier, because win32).
Privately, I'm going to use the "env" argument to add a key binding that
starts a shell with a FILE environment variable set to the currently
playing file, so this is very useful to me.
Note: breaks windows, so for example youtube-dl on windows will not work
anymore. mp_subprocess2() has to be implemented. The old functions are
gone, and subprocess-win.c is not built anymore. It will probably work
on Cygwin.

Rather than after tone-mapping. This prevents overflow when the
pre-tonemapped signal contains inputs exceeding sig_peak. I also
realized that with this clipping in place, post-clipping no longer needs
to be done, so this isn't even particularly slower.
The only two exceptions to the rule are "clip" and "linear", which
relied on the post-clipping to do their tone mapping properly.

This normally gets printed by libplacebo itself when initializing the

This probably makes it much faster (I wouldn't know, I didn't run any
benchmarks ). Seems to work as well (although I'm not sure, it's not
like I'd perform rigorous tests).
The scale_zimg test seems to mysteriously treat color in fully
transparent alpha differently, which makes no sense, and isn't visible
(but makes the test fail). I can't be bothered with investigating this
more. What do you do with failing tests? Correct, you disable them. Or
rather, you disable whatever appears to cause them to fail, which is the
threading in this case.
This change follows mostly the tile_example.cpp. The slice size uses a
minimum of 64, which was suggested by the zimg author. Some of this
commit is a bit inelegant and weird, such as recomputing the scale
factor for every slice, or the way slice_h is managed. Too lazy to make
this more elegant.
zimg git had a regressio around active_region (which is needed by the
slicing), which was fixed in commit 83071706b2e6bc634. Apparently, the
bug was never released, so just add a warning to the manpage.

The intention is to add slice-threading to the wrapper. For that
purpose, move all zimg related state to a new struct mp_zimg_state.
There is now an array of instances of this struct. The intention is to
have one instance for each thread. As of this commit, this is hardcoded
to 1 thread; the following commit extends this.

It turns out that the AMD driver doesn't bother to set the size
field in the descriptor for an exported VA surface. I guess they
assume the caller can always use lseek() and don't bother. So, we
need to use lseek() in these situations.

This can be used to make vo_libmpv render video to a memory buffer. It
only adds a new backend API that takes memory surfaces. All the render
API (such as frame rendering control and so on) is reused.
I'm not quite convinced of the usefulness of this, and until now I
always resisted providing something like this. It only seems to
facilitate inefficient implementation. But whatever.
Unfortunately, this duplicates the software rendering glue code yet
again (like it exists in vo_x11, vo_wlshm, vo_drm, and probably more).
But in theory, these could reuse this backend in the future, just like
vo_gpu could reuse the render_gl API.

XDG is stupid, so change back to the standard behavior. Unfortunately,
most users will now have the XDG one, so we will still need to load
this. (This is exactly the same problem as when XDG support was
introduced, just the other way around).
This should not affect any normal users. Hopefully I tested this well
enough; my intention is not to torment miserable XDG fans; they can keep
using their config dir if they want it.
This changes behavior in two cases:
- new users (now creates ~/.mpv/ instead of ~/.config/mpv/)
- users which have both directories
The latter case will behave subtly or obviously different, not sure.
Just fix your shit.

De-emphasize it, since a user should usually not use it. This _could_ be
used to make the cache seekable with --cache=no, but it's better and
more intuitive to use --cache=yes. As such, the only use of this is for
debugging. I'm not quite sure if this should be removed entirely, but I
still see some value in it (for example if you want the cache lookahead,
but you're using a stream where cache seeking is somehow broken).

For testing in VMs I guess?
This features a very broken hack that probably works. Though I didn't
test the packed format case. Again, the mismatch is essentially due to
big endian byte addresses decreasing as bit addresses increase, so you
can't represent a bit position in a byte stream with a single address,
which the mpv metadata does.
OSD is broken because repack.c doesn't support big endian. You'll have
to live with it.

The recent changes to the image format metadata broke big endian, and
that was intentional. Some things are inherent to little endian (like
the idea to coalesce bit and byte offsets into a single bit offset), and
they don't be fixed. But some obvious things can be fixed, such as
marking LE vs. BE formats the right way around on BE hosts.
The metadata is formally still in LE, except that if the LE/BE flag
matches the host endian, the host endian can be used when accessing
packed formats with bit shifts, or when computing byte aligned component
byte offsets. The former may work because formats with LE/BE variants
use the same bit offsets after byte swapping, the latter may work
because little endian is the natural concept for addressing memory. But
it will "subtly" fail to do the right thing in some cases, and code
using this can't know, so have fun.
Many things are broken, but this makes e.g. vo_gpu mostly work.
My general opinion about BE computers is that you should get a better
computer, you can get one for free from any garbage dump.

Mainly, X2RGB10BE is added. Add our own unpack test for this format.
Also, swscale seems to have added support for GBRPF conversion.

|

IMGFMT_RGB30 was added first; FFmpeg added AV_PIX_FMT_X2RGB10 later.
This is exactly the same, so treat them as such. For some reason,
libswscale still seems to output incompatible data - not sure what this
is about, but I'm not going to debug it.
|

Instead of applying this only to "regular" formats, do it with all
formats.

could probably be removed, but whatever.

This change attempts to fix detection of how endian swapping is to be
performed. Details can be found in the code comments.
It should not change anything, other than fixing handling of the
X2RGB10BE ffmpeg pixel format. This format was detected incorrectly, and
the component location metadata was discarded due to an internal
consistency check. With this commit, it is handled correctly. At first I
thought the X2RGB10BE ffmpeg pixdesc metadata was wrong, but it appears
to be correct. The problem with this format is that it's the first
packed RGB format that requires bit shift to access, and where the
endian word size is larger than the (rounded up) component size, all
while pixdesc would "require" you to perform 3 memory accesses (instead
of 1), and the code tries to reverse this.
It appears that trying to use the pixdesc metadata is much, much more
work than just duplicating it in a saner form. To be fair, most problems
are with big endian, and the mpv internal format does not care much
about endian _hosts_.

For cases in which the requirements of the GPU API prevent directly
uploading a texture with a given stride, we need to fix the stride
manually in host memory. This incurs an extra memcpy, but there's not
much we can do about it. (Even in `ra_gl` land, the driver will just
hide this memcpy from the user)
Note: This code could be done better. It could only copy as many texels
as needed, and it could pick a stride that's a multiple of
`gpu->limits.align_tex_xfer_stride` for better performance. Patches

This brings mpv's tone mapping more in line with industry standard

entirely. In theory we could revisit this, if we ever make black point

glslang accepted this, perhaps erronneously, but mesa does not. It seems
to be incorrect. A caveat is that this means *all* SSBOs are now
coherent, but since we only use SSBOs for peak detection, that's a
non-issue. (And besides, marking something as coherent when we don't
perform any synchronization commands on it should be a no-op anyway)

AOs which use the "push" API must set this field now. Actually, this was
sort of always required, but happened to work anyway. The future
intention is to use device_buffer as the pre-buffer amount, which has to
be available right before audio playback is started. "Pull" AOs really
need this too conceptually, just that the API is underspecified.
From what I can see, only ao_null did not do this yet.

I feel like this makes slightly more sense. At least it doesn't include
the potentially arbitrary constant latency that is generally included in
the delay value. Also, the buffer status doesn't matter - either we've
filled the entire buffer (then we can wait this long), or there's not
enough data anyway (then the core will wake up the thread if new data is
available).
But ultimately, we have to guess, unless the AO does notify us with
ao_wakeup_playthread().
Draining may now wait for no reason up to 1/4th of the total buffer
time. Shouldn't be a disimprovement in practice.

It's conceivable that ao->driver->reset() will make the audio API wait
for ao_read_data() (i.e. its audio callback) to return. Since we
recently moved the reset() call inside the same lock that ao_read_data()
acquires, this could deadlock. Whether this really happens depends on
how exactly the AO behaves. For example, ao_wasapi does not have this
problem. "Push" AOs are not affected either.
Fix by moving it outside of the lock. Assume ao->driver->start() will
not have this problem.
Could affect ao_sdl, ao_coreaudio (and similar rotten fruit AOs). I'm
unsure whether anyone experienced the problem in practice.

Instead of the relatively subtle underflow handling, simply signal
whether the stream is in a playing state. Should make it more robust.
Should affect ao_alsa and ao_pulse only (and ao_openal, but it's
broken).
For ao_pulse, I'm just guessing. How the hell do you query whether a
stream is playing? Who knows. Seems to work, judging from very
superficial testing.
|

The feeder thread basically woke up the core and itself too often, and
caused some CPU overhead. This was caused by the recent buffer.c
changes.
For one, do not let ao_read_data() wake up the core, and instead rely on
the feeder thread's own buffer management. This is a bit strange, since
the change intended to unify the buffer management, but being more
consequent about it is better deferred to later, when the buffer
management changes again anyway. And also, the "more" condition in the
feeder thread seems outdated, or at least what made it make sense has
been destroyed, so do something that may or may not be better. In any
case, I'm still not getting underruns with ao_alsa, but the wakeup
hammering is gone.

Commit 6a13954d67143fb lowered the frequency of wakeups with this
condition. But it seems it sometimes the audio sync mode really should
get the wakeup before the frame is rendered. Normally, vo_thread is
supposed to perform this wakeup. Now the wakeup frequency is twice of
what should be needed - whatever, maybe it can be fixed properly once or
if timing is moved to the VO entirely in the future.

This affects "pull" AOs only: ao_alsa, ao_pulse, ao_openal, ao_pcm,
ao_lavc. There are changes to the other AOs too, but that's only about
renaming ao_driver.resume to ao_driver.start.
ao_openal is broken because I didn't manage to fix it, so it exits with
an error message. If you want it, why don't _you_ put effort into it? I
see no reason to waste my own precious lifetime over this (I realize the
irony).
ao_alsa loses the poll() mechanism, but it was mostly broken and didn't
really do what it was supposed to. There doesn't seem to be anything in
the ALSA API to watch the playback status without polling (unless you
want to use raw UNIX signals).
No idea if ao_pulse is correct, or whether it's subtly broken now. There
is no documentation, so I can't tell what is correct, without reverse
engineering the whole project. I recommend using ALSA.
This was supposed to be just a simple fix, but somehow it expanded scope
like a train wreck. Very high chance of regressions, but probably only
for the AOs listed above. The rest you can figure out from reading the
diff.

wasapi/coreaudio/sdl were affected, alsa/pusle were not.
The confusion here was that resume() has different meaning with pull and
push AOs.

This should make --term-title work in Windows 8.1 and below.
OSC sequences are defined in ECMA-48. The 'Change Window Title' command,
as far as I can tell, is a de-facto standard defined by xterm[1]. In
either case, this code is probably still not standards-compliant.
This also changes mp_write_console_ansi to convert to UTF-16 before
parsing control sequences, because that made it easier to pass the OSC
param to SetConsoleTitleW. I think it's also more correct to do it this
way, even though it doesn't really matter much for our limited terminal
parsing. As a side-effect of this, mp_write_console_ansi no longer
mutates its argument.

Regression since the recent refactor. How did nobody notice?
This happened because the push code now calls the function for the pull
code. Both the former and latter apply the volume, so oops.

The recent change to the common code removed all calls to ->drain. It's
currently emulated via a timed sleep and polling ao_eof_reached(). That
is actually fallback code for AOs which lacked draining. I could just
readd the drain call, but it was a bad idea anyway. My plan to handle
this better is to require the AO to signal a underrun, even if
AOPLAY_FINAL_CHUNK is not set. Also reinstate not possibly waiting for
ao_lavc.c. ao_pcm.c did not have anything to handle this; whatever.

This simply printf()s a concatenation of the provided string and the
relevant escape sequences. No idea what exactly defines this escape
sequence (is it just a xterm thing that is now supported relatively
widely?), and this simply uses information provided on the linked github
issue.
Not much of an advantage over --term-status-msg, though at least this
can have a lower update frequency. Also I may consider setting a default
value, and then it shouldn't conflict with the status message.

This is preparation to further cleanups (and eventually actual
improvements) of the audio output code.
AOs are split into two classes: pull and push. Pull AOs let an audio
callback of the native audio API read from a ring buffer. Push AOs
expose a function that works similar to write(), and for which we start
a "feeder" thread. It seems making this split was beneficial, because of
the different data flow, and emulating the one or other in the AOs
directly would have created code duplication (all the "pull" AOs had
their own ring buffer implementation before it was cleaned up).
Unfortunately, both types had completely separate implementations (in
pull.c and push.c). The idea was that little can be shared anyway. But
that's very annoying now, because I want to change the API between AO
and player.
This commit attempts to merge them. I've moved everything from push.c to
pull.c, the trivial entrypoints from ao.c to pull.c, and attempted to
reconcile the differences. It's a mess, but at least there's only one
ring buffer within the AO code now. Everything should work mostly the
same. Pull AOs now always copy the audio data under a lock; before this
commit, all ring buffer access was lock-free (except for the decoder
wakeup callback, which acquired a mutex). In theory, this is "bad", and
people obsessed with lock-free stuff will hate me, but in practice
probably won't matter. The planned change will probably remove this
copying-under-lock again, but who knows when this will happen.
One change for the push AOs now makes it drop audio, where before only a
warning was logged. This is only in case of AOs or drivers which exhibit
unexpected (and now unsupported) behavior.
This is a risky change. Although it's completely trivial conceptually,
there are too many special cases. In addition, I barely tested it, and
I've messed with it in a half-motivated state over a longer time, barely
making any progress, and finishing it under a rush when I already should
have been asleep. Most things seem to work, and I made superficial tests
with alsa, sdl, and encode mode. This should cover most things, but
there are a lot of tricky things that received no coverage. All this
text means you should be prepared to roll back to an older commit and
report your problem.
