It was done once before but later reverted for testing reasons. This
time it's permanent though since I can test this VO on ARM and with an
up to date system.

1.27 would have been nicer but ubuntu 22.04 is on 1.25 so we'll just
compromise.

While adding fractional scale support, the coordinates for wayland
changed to always include the scaling parameter. The pointer stuff
actually did too. However, the check_for_resize function used the
unscaled, local surface coordinates. Likely, it was neccesary at the
time since wl->geometry used to report unscaled coordinates. In light of
that, we can just simply use mouse_x/y instead for this function to make
it work correctly with the right/bottom edges. mouse_unscaled becomes
completely unneccesary, so just drop it.
Some minor style changes included just because.

Which is wl->video_surface for vo_dmabuf_wayland.
Listening on wl->surface results in freezes if it is occluded and
culled by the compositor. Which mutter does, and the wl_surface::frame
spec warns about:
> A server should avoid signaling the frame callbacks if the
> surface is not visible in any way, e.g. the surface is off-screen,
> or completely obscured by other opaque surfaces.

ra_ctx_opts.want_alpha and vo_wayland_set_opaque_region's alpha
argument are only used as bool but both are ints. Particularly for the
function argument, passing a 0 or 1 is confusing - at first glance it
looks like you're specifying an alpha value of 0 or 1.
Since they're only used as bools, make them bools.

c78482045444c488bb7948305d583a55d17cd236 introduced a bool option type
as a replacement for the flag type, but didn't actually transition and
remove the flag type because it would have been too much mundane work.

This was originally dropped because it was thought to be unneeded at the
time, but at least some devices (rockchip) apparently are still on old
compositors that use linux-dmabuf v2. It's not much code, and for
testing purposes it's good to have around since it's hard to test
drmprime otherwise. Some minor additions are here to support the newly
added vaapi-format mapping in v2 of the protocol.
This reverts commit a5b9d529eec8d4bb6fc858143337c3573ec8afd0.

This protocol is pretty important since it finally lets us solve the
longstanding issue of fractional scaling in wayland (no more mpv doing
rendering over the target resolution and then being scaled down). This
protocol also can completely replace the buffer_scale usage that we are
currently using for integer scaling so hopefully this can be removed
sometime in the future. Note that vo_dmabuf_wayland is omitted from the
fractional scale handling because we want the compositor to handle all
the scaling for that VO.
Fixes #9443.

This is in preparation for fractional scaling support. Basically, redo
all the coordinates in wayland so that wl->geometry is equal exactly to
what is being put out to the screen (no extra wl->scaling multiplication
required). The wl->vdparams variable is also eliminated for simplicity.
This changes mpv's behavior on wayland with hidpi scaling but that will
be addressed in more detail with the next commit.

Officially, the most cursed part of the wayland code in mpv (third or
fourth try now?) This time, let's allocate a pool during init
(arbitrarily set to the maximum swapchain length mpv allows, 8; don't
even know if this actually works in wayland). Then we add/remove
feedbacks from the pool during the lifecycle of the VO, and clean it up
all at the end. Hopefully, this does the trick for good this time.

This ended up being a bad idea. The problem is that it introduces
ordering when destroying events (something we weren't worried about
before) and Lynne pointed out a problem with the callback not also being
destroyed before the surface in IRC. Just undo this and go with a
different approach (next commit). P.S. the wayland_dispatch_events name
change is kept though because I like that better.
This reverts commit aa8ddfcdf30c4ffb38f3ec5d6663bbabf0b7b4df.

The only real reason this was ever supported is because it was
dramatically simpler than v4, so it was put in as an initial
implementation. Later, v4 support was added and we left v2 for
compatibility, but let's just drop it. Compositors all use v4 nowadays,
and v2 is significantly limited (no modifier support for example). It's
better to just remove this dead code for simplicity.

This was already returning true/false but the type was int. Also
simplify a few places in the wayland contexts where we can just return
the value of this function instead of doing redundant checks.

There's several functions that are used for initializing mpv on a
certain platform (x11, wayland, etc.). These currently are all int, but
they actually return 1 and 0 like a boolean. This gets a bit confusing
because actual vo preinit functions return 0 and -1 instead. Just make
these all bool instead and return true/false to make it clearer.

Similar to some other issues we've had with unprocessed compositor
events. When quitting mpv, there's two things we should be doing:
dispatching any last minute wayland events and then waiting for a
compositor reply. Luckily, there's already an internal helper for this
(renamed to wayland_dispatch_events for consistency) that we can use.
All of the special casing of wl->feedback becomes unneccesary and we can
remove this from vo_wayland_state with this method. Fixes #110022.

The new single-pixel-buffer protocol is designed to optimize the case
for using a solid color as an underlay wl_surface. It works the same as
the wl_shm 1x1 pixel trick currently used, but it allows the compositor
to make optimizations with more certainty than the wl_shm trick.

The content-type protocol allows mpv to send compositor a hint about the
type of content being displayed on its surface so it could potentially
make some sort of optimization. Fundamentally, this is pretty simple but
since this requires a very new wayland-protocols version (1.27), we have
to mess with the build to add a new define and add a bunch of if's in
here. The protocol itself exposes 4 different types of content: none,
photo, video, and game.
To do that, let's add a new option (wayland-content-type) that lets
users control what hint to send to the compossitor. Since the previous
commit adds a VOCTRL that notifies us about the content being displayed,
we can also add an auto value to this option. As you'd expect, the
compositor hint would be set to photo if mpv's core detects an image,
video for other things, and it is set to none for the special case of
forcing a window when there is not a video track. For completion's sake,
game is also allowed as a value for this option, but in practice there
shouldn't be a reason to use that.

666cb91cf12a4f8b42087530104513b0fc4ba16d added support for v4 of the
dmabuf protocol. This was meant to be optional and the fallback support
for the old v2 (dates back to 2017[0] well before the 1.15
wayland-protocol version we depend on) was maintained. However, v4 added
several new functions and structs that of course aren't defined in old
protocol versions so naturally this breaks the build on those systems.
Since this is just a niche feature and not really critical to overall
wayland support in mpv, just give in and add another check in the build
system and #if out the newer stuff in wayland_common. v4 of linux-dmabuf
depends on wayland protocols 1-24[1], so go ahead and make that our new
check. Fixes #10807.

Originally, I considered warning once to be useful for figuring
out whether the change in logic regarding resetting requested
mode actually fixed the reported issue or not, but alas not everyone
was happy with that decision. Thus the log level will always be
debug. This enables us to lose one level of indent as well as a
variable, which is always positive.
Additionally, make the message more explicit regarding what could
possibly be implied by the mismatch, as it seems like this was
not always clear.
|
| |
|
|
|
|
|
|
|
| |
Otherwise mpv and the compositor can end up in an eternal loop where
mpv requests one mode, and compositor tells that the mode is not
that (and will most likely not change).
Additionally, log these mismatches - first time as a warning, and
later as debug logging.

Pulled from https://github.com/mpv-player/mpv/pull/10382
The zwp_linux_dmabuf_v1 protocol version 4 provides a file descriptor
containing both formats and modifiers, which makes it possible for the
compositor to import the buffers onto planes using explicit modifiers.
This is an extremely important efficiency improvement, as the 3D
hardware can be left powered off altogether, the vaapi buffer being sent
directly from the video hardware to the display controller.
It could be possible to support zwp_linux_dmabuf_v1 version 3 as well,
but there is no reason beyond compatibility with old stacks. I would
recommend to ditch version 2 as well, as modifier-less formats aren’t
very useful nowadays.

The wayland presentation time code currently always assumes that only
CLOCK_MONOTONIC can be used. There is a naive attempt to ignore clocks
other than CLOCK_MONOTONIC, but the logic is actually totally wrong and
the timestamps would be used anyway. Fix this by checking a use_present
bool (similar to use_present in xorg) which is set to true if we receive
a valid clock in the clockid event. Additionally, allow
CLOCK_MONOTONIC_RAW as a valid clockid. In practice, it should be the
same as CLOCK_MONOTONIC for us (ntp/adjustime difference wouldn't
matter). Since this is a linux-specific clock, add a define for it if it
is not found.

In wayland-protocols 1.25, xdg-shell got a version bump which added the
configure_bounds event. The compositor can send this to clients to
indicate that they should not resize past a certain size. For mpv, we'll
choose to only listen to this on reconfig events (i.e. when the window
first appears and if the video resolution changes later in the
playlist). However, this behavior is still exposed as a user option
(default on) because it will neccesarily conflict with a user setting a
specific geometry size and/or window scale. Presumably, if someone is
setting a really large size that goes beyond the bounds of their
monitor, they actually want it like that. The wayland-protocols version
is newer-ish, but we can get around having to poke the build system by
just using a define that exists in the generated xdg-shell header.

Wayland had some specific code that it used for implementing the
presentation time protocol. It turns out that xorg's present extension
is extremely similar, so it would be silly to duplicate this whole mess
again. Factor this out to separate, independent code and introduce the
mp_present struct which is used for handling the ust/msc values and some
other associated values. Also, add in some helper functions so all the
dirty details live specifically in present_sync. The only
wayland-specific part is actually obtaining ust/msc values. Since only
wayland or xorg are expected to use this, add a conditional to the build
that only adds this file when either one of those are present.
You may observe that sbc is completely omitted. This field existed in
wayland, but was completely unused (presentation time doesn't return
this). Xorg's present extension also doesn't use this so just get rid of
it all together. The actual calculation is slightly altered so it is
correct for our purposes. We want to get the presentation event of the
last frame that was just occured (this function executes right after the
buffer swap). The adjustment is to just remove the vsync_duration
subtraction. Also, The overly-complicated queue approach is removed.
This has no actual use in practice (on wayland or xorg). Presentation
statistics are only ever used after the immediate preceding swap to
update vsync timings or thrown away.

A bad person (AKA me) merged this stuff without paying close enough
attention to the code style. Reformat this to be in-line with the rest
of the wayland code and general mpv style (braces for functions on the
next line, horizontally aligning arguments, some cosmetic cleanups for
wayland_common.h, etc.).

This driver makes use of dmabuffer and viewporter interfaces
to enable efficient display of vaapi surfaces, avoiding
any unnecessary colour space conversion, and avoiding scaling
or colour conversion using GPU shader resources.

A bit of a personal pet peeve. vulkan, opengl, and wlshm all had
different methods for doing wayland's "check for visibility before
drawing" thing. The specific backend doesn't matter in this case and the
logic should all be shared. Additionally, the external swapchain that
the opengl code on wayland uses is done away with and it instead copies
vulkan by using a param. This keeps things looking more uniform across
backends and also makes it easier to extend to other platforms (see the
next couple of commits).

This was originally added in f2afae55e95b4b1eec1aeb828ba6ff1f0695d993
for unclear reasons (way to go me). This concept is clearly incorrect.
It doesn't matter what state the window is in. As soon as mpv detects a
scale change, it needs to reset the buffer scale of the window. Just
remove all this junk and put wl_surface_set_buffer_scale in
set_surface_scaling like it should be. Related issue: #9426.

The value of the border option should always match what the actual state
of the window is. Previously if a compositor rejected the request by
mpv, it did not correct itself. Also add some code to keep track of
decoration requests. Anytime the state is changed, make the last saved
request again (doesn't hurt and seems like intuitive behavior).
Unfortunately, this isn't foolproof since options only send callback if
the value is changed. (ex. on sway if the floating window has no border,
and then is titled, setting the border value to "yes" does nothing since
tiling the window already set the border value to "yes").

There's currently some touch related code in mpv wayland, but clearly
nobody actually uses because it's a broken mess. Initially an attempt to
distinguish between two finger touches and one finger touch was made,
but there's not a good way to make this work. For whatever reason,
initiating either xdg_toplevel_resize or xdg_toplevel_move blocks any
other touch events from occurring (at least in plasma). Trying to call
these functions anywhere else is not really useful since the serial will
be invalid outside of the touch down events (well it would work in the
touch up event but that's just silly).
Anyways, let's just make this work sanely. Eliminate the touch entries
variable completely because it's pointless. Only one finger event is
ever considered at a time. Touches besides the initial one are all
ignored. If a user touches and drags within the touch edge radius, then
a resize event occurs. If the user touches and drags elsewhere on the
window, a move event occurs. A single tap displays the osc (which is
clickable if you tap again). A double tap toggles fullscreen.
Additionally, the default touch edge radius of 64 pixels is way too big
(at least I think so). Cut this in half to 32 which feels a lot better
(on a pinephone using plasma mobile anyway).

Regression from 24357cb. It's ugly but unfortunately keeping tracking of
the last toplevel width and height really is the best way to solve this
problem and removing it was a mistake. Compositors don't always send
width/height coordinates of the actual window. The easiest way to
trigger this is by changing window-scale/current-window-scale and then
unfocusing the window. The compositor will send another toplevel
configure event with coordinates of the window before the resize. Maybe
compositors could be smarter but multiple ones do this (sway, gnome,
plasma), so just keep the old workaround. The only difference this time
is that the toplevel width/height is saved at the very beginning which
also covers the case where it equals 0 (i.e. weston).

The source of many geometry woes. There's some loosely related toplevel
things that should be cleaned up/fixed. First of all,
VO_EVENT_LIVE_RESIZING is actually completely useless. It might have
been useful sometime in the past, but there's no point. It doesn't
"speed up" resizing in any way and appears to be originally for cocoa.
Just remove it.
Way back in the day, toplevel_width/height was added as a workaround for
when we got uncoorperative (i.e. wrong) width/height coordinates from
the compositor in this event. Basically it could happen due to numerous
reasons but a lack of atomic commits was part of the reason and also
mpv's geometry handling then was a lot rougher. We *shouldn't* need this
workaround anymore. The width/height values are only used exactly when
we need them. If mpv sets geometry on its own, it should still be the
right dimensions.
Related to the above, mpv never actually propertly handled the case
where width or height was equal to 0. According to the xdg-shell spec,
"If the width or height arguments are zero, it means the client should
decided its own window dimension." An example of a compositor doing this
is weston. It's, unsurprisingly, broken. Getting out of fullscreen or a
maximized state does not restore the old window size like it should. The
right way to handle this is to just return near the end of the function
if we have a 0 for either argument and before any geometry is set
(wl->geometry's width or height can never be zero). Luckily, state
changes are already being detected so they just trigger the goto when
needed.
Finally, e2c24ad mistakenly removed the VO_EVENT_EXPOSE. There are edge
cases where this is needed and it's safer to just force a redraw here
when the window gets activated again. Just force wl->hidden to false
first and then trigger the expose.

Another day, another wayland refactor. Way back when, dcc3c2e added
support for the hidpi-window-scale option (something you probably should
never set to no but whatever) to wayland. Well technically, it never had
any runtime toggling support (don't remember if detecting when vo_opts
changed was possible or not then; maybe not). Anyways in the process of
fixing that, I went ahead and refactored how this is all handled. The
key difference is that when hidpi-window-scale is disabled, wl->scaling
is directly set to 1 instead of forcibly setting
wl->current_output->scale to 1. Note that scaling operations don't
always require a geometry reset/resize so set_surface_scaling needs to
be separate from set_geometry. The logic here is kind of complicated but
it (should) be correct.

A subtle regression from c26d833. On sway if mpv was set to be a
floating window in the config, set_buffer_scale would actually get
applied twice according to the wayland log. That meant a 1920x1080
window would appear as a 960x540 window if the scale of the wl_output
was set to 2. This only affected egl on sway (didn't occur on weston and
was too lazy to try anything else; probably they were fine). Since
wl->render is initially false, that meant that the very first run
through the render loop returns false. This probably caused something
weird to happen with the set_buffer_scale calls (the egl window gets
created and everything but mpv doesn't write to it just yet) which makes
the set_buffer_scale call happen an extra time. Since it was always
intended for mpv to initally render, this is worth fixing. Just chnage
wl->render to wl->hidden (again) and flip the bools around. That way,
the initial false value results in render == true and mpv tries to draw
on the first pass. This fixes the weird scaling behavior because
reasons.

Mostly a cosmetic change that (hopefully) makes things look better. Some
functions and structs that were previously being exported in the wayland
header were made static to the wayland_common.c file (these shouldn't be
accessed by anyone else).

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.
