Used to be used by vo_x11, and some other situations where software
conversion was employed. Haven't seen anyone complain about how software
brightness controls went away (originating from mplayer), so whatever,
it won't be needed again.

This fixes two issues with invalid value after 38/48:
- It was not detected correctly and ended up skipping 4 instead of 0.
- The intent was to skip 0, but it's better to skip the rest.
Behavior with valid 2/5 after 38/48 was correct and is unaffected.

terminal_get_size also works on windows. This is useful because now
tct also works on Windows with native VT console.
|

|
|
|

The narrower-by-1 width is not required with a native VT console
because the wrapping behavior is the same as on *nix on such case.

In the wayland code, the left mouse click is treated a bit differently.
Dragging the left click allows mpv to request a window move to the
compositor. In some cases, this can also request a window resize if the
osc-windowcontrols are enabled. These functions had the strange side
effect of messing up mpv's deadzone (it seemed to disappear completely).
A harmless enough workaround is to just explictly send an UP event for
left click after the move/resize functions are finished executing. The
xdg_toplevel move and resize functions both finish after the button
press is let go, so we are guarenteed to have the left click in the UP
state here. Sending this event probably unconfuses some calculation
somewhere thus fixing the deadzone bug. It feels a little silly, but
it's safe and works. Fixes #7651.

When stats.lua is used without a video window then it uses the terminal.
On Windows, however, so far it disabled ansi escape sequences and used
plaintext unless ANSICON env is set.
It's unclear why it's disabled on windows, because at the time it was
added it only used bold by default and mpv ansi emulation on windows
already supported bold at that time.
We can guess that it was disabled because if the same config is used on
both linux and Windows, and it had complex escape sequences for
stats.lue, then it would be emulated incorrectly on Windows.
This shouldn't be an issue anymore, as the last two commits both enhance
the emulation to be quite complete (and graceful where it's not), and
also enable the much-more complete native VT terminal when possible
(Windows 10).
Just remove this windows exception at stats.lua.

This enables native and more complete escape-sequence handling instead
of our emulation. E.g. it supports 256/true colors, and more.
This should get enabled automatically on Windows 10 build 16257
(August 2017) or later.

Previously an SGR sequence was emulated correctly only if:
- It had exactly 1 or 2 numeric values (not 0).
- Only reset, bold, and foreground colors were supported.
- 256/true colors were not skipped correctly with their sub-values.
Now it supports the same as before, plus:
- 0-16 (inclusive) numeric values, e.g. \e[m now resets correctly.
- Supports also codes for background color, reverse, underline* .
- Supports also codes for default intensity/fg/bg/reverse/underline.
- 256/true colors are recognized and skipped gracefully.
* Reverse/underline seem to work only on windows 10.

Move lookup GBRP or planar gray/alpha formats to separate functions in
some cases.
Make setup_regular_rgb_packer() not use a 4:4:4 YUV format to "pass"
RGB. This was used as a "trick" to avoid the stupid GBRP plane
permutation, but it confused severely, so get rid of it. Just do the
reordering, even if the zimg wrapper itself will reorder it back (which
is so stupid that I used the other approach at first). The comment
saying IMGFMT_420P was bogus of course; typically it was IMGFMT_444P.

This was inconsistent for unknown reason. monob was the way we wanted
it, and handling of monow was missing.
See the previous "img_format: add some mpv-only helper formats" commit.
Matters for the zimg wrapper.

mp_imgfmt_get_forced_csp() should be consistent with the MP_CSP_RGB/YUV
flags.
At least the different handling of the XYZ exception was a mess, even if
the result was the same.

Utterly useless, but the intention is to make dealing with corner case
pixel formats (forced upon us by FFmpeg, very rarely) less of a pain.
The zimg wrapper will use them. (It already supports these formats
automatically, but it will help with its internals.)
Y1 is considered RGB, even though gray formats are generally treated as
YUV for various reasons. mpv will default all YUV formats to limited
range internally, which makes no sense for a 1 bit format, so this is a
problem. I wanted to avoid that mp_image_params_guess_csp() (which
applies the default) explicitly checks for an image format, so although
a bit janky, this seems to be a good solution, especially because I
really don't give a shit about these formats, other than having to
handle them. It's notable that AV_PIX_FMT_MONOBLACK (also 1 bit gray,
just packed) already explicitly marked itself as RGB.

When I added mp_regular_imgfmt, I made the chroma subsampling use the
actual chroma division factor, instead of a shift (log2 of the actual
value). I had some ideas about how this was (probably?) more intuitive
and general. But nothing ever uses non-power of 2 subsampling (except
jpeg in rare cases apparently, because the world is a bad place).
Change the fields back to use shifts and rename them to avoid mistakes.

yap8/yap16.

One not-so-nice hack in the wayland code is the assumption of when a
window is hidden (out of view from the compositor) and an arbitrary
delay for enabling/disabling the usage of presentation time. Since you
do not receive any presentation feedback when a window is hidden on
wayland (a feature or misfeature depending on who you ask), the ust is
updated based on the refresh_nsec statistic gathered from the previous
feedback event.
The flaw with this is that refresh_nsec basically just reports back the
display's refresh rate (1 / refresh_rate * 10^9). It doesn't tell you
how long the vsync interval really was. So as a video is left playing
out of view, the wl->last_queue_display_time becomes increasingly
inaccurate. This led to a vsync spike when bringing the mpv window back
into sight after it was hidden for a period of time. The hack for
working around this is to just wait a while before enabling presentation
time again. The discrepancy between the "bogus"
wl->last_queue_display_time and the actual value you get from the
feedback only happens initially after a switch. If you just discard
those values, you avoid the dramatic vsync spike.
It turns out that there's a smarter way to do this. Just use mp_time_us
deltas. The whole reason for these hacks is because
wl->last_queue_display_time wasn't close enough to how long it would
take for a frame to actually display if it wasn't hidden. Instead, mpv's
internal timer can be used, and the difference between wayland_sync_swap
calls is a close enough proxy for the vsync interval (certainly better
than using the monitor's refresh rate). This avoids the entire conundrum
of massive vsync spikes when bringing the player back into view, and it
means we can get rid of extra crap like wl->hidden.

UB sanitizer complains that aval<<24 (if >=128) cannot be represented as
int. Indeed, we would shift a bit into the sign of an int, which is
probably UB or implementation defined (I can't even remember, but the
stupidity of it burns). So technically, ubsan might be right.
Change aval to uint32_t, which I don't think has a chance of getting
promoted to int. Change the other *val to uint32_t too for cosmetic
symmetry.
So we have to obscure the intention of the code (*val can take only 8
bits) out of language stupidity. How nice. (What a shitty language.)

A mkv sample file was provided to me, which contained a moving PGS
subtitle track, with the same track rendered into the video as
reference. The subtitle track appeared to stutter (while the video one
was smooth). It turns out this was a timestamp rounding issue in mpv.
The subtitle timestamps in the file match the video ones exactly.
They're the same within the mpv demuxer too. Unfortunately, the
conversion from and to libavcodec timestamps is lossy, because mpv uses
a non-integer timebase, while libavcodec supports integers only. See
mp_pts_to_av() and mp_pts_from_av(). The recovered timestamp is almost
the same, but is off by a very minor part. As a result, the timestamps
won't compare equal, and if that happens, display of the subtitle frame
is skipped. Subtitle timestamps don't go through this conversion
because... libavcodec is special? The libavcodec subtitle API is
special.
Fix this by giving it a microsecond of slack. This is basically as if we
used an internal microseconds integer timebase, but only for the purpose
of image subtitle display.
The same could happen to sd_ass, except in practice it doesn't. ASS
subtitles (well, .ass files) inherently use a timebase incompatible to
video, so to ensure frame exactness, ASS timestamps are usually set to
slightly before the video frame's.
Discussion of better solutions:
One could rewrite mpv not to use float timestamps. You'd probably pick
some integer timebase instead (like microseconds), which would avoid the
libavcodec interop issue. At the very least this would be a lot of work.
It would be interesting to know whether the rounding in ther mpv<->lavc
timestamp conversion could be fixed to round-trip in this case. The
conversion tries to avoid problems by using the source timebase (e.g.
milliseconds with mkv). But in general some rounding is unavoidable,
because something between decoder and lowest demuxer layer could
transform the timestamps.
One could extend libavcodec to attach arbitrary information to avpacket
and return it in the resulting avframe. To some degree, such a mechanism
already exists (side data). But there are certain problems that make
this unfeasible and broken.
One could pass through exact mpv float timestamps by reinterpret-casting
them to int64_t, the FFmpeg timestamp type. Actually mpv used to do
this. But there were problems, such as FFmpeg (or things used by FFmpeg)
wanting to interpret the timestamps. Awful shit that make mpv change to
the current approach.
There's probably more but I'm getting bored. With some luck I wasted
precious seconds of your life with my nonsense.

It is more consistent for editions/chapters to go below either
the title or filename. They are all descriptive strings about
the media itself and not file metadata like filesize.

Edition information is conditional based on there being more than
one edition present. It is printed on the same line as Chapters to

zsh often sets DECCKM (i.e. Cursor Key Mode) meaning the arrow keys

definitions.

e1e714ccc introduced a regression here when unloading a track (e.g. on
VO/AO initilization error), due to no corresponding option existing for
video/audio tracks with orders above 0, but the loop in
`mp_deselect_track` being hard-coded to clear tracks up to NUM_PTRACKS.
Introduce the simplest possible hackaround.

In theory this mostly happens automatically, especially after the 5
vsync limit disables this already. But if we uninit before 5 vsyncs are
rendered, this can get left in a dangling 'enabled' state, which leaks a
debug report callback.
Always explicitly disable it just to be on the safe side.

I must have messed this up when I actually added the Y210 format
(because that one is correct). So my comment in the commit adding this
about the FFmpeg pixfmt doxygen being wrong was wrong.
I'd like to use this opportunity to complain once more about the
existence of these terrible pixel formats.

Again worthless, slow, and only for libswscale parity.
With this, we support all formats libswscale supports, except bayer
input, and rgb4/bgr4 output. We even support some formats libswscale
doesn't.
It's possible that the zimg wrapper isn't always as fast as libswscale.
But there is optimization potential: the inner repack loops are
self-contained enough that they could be reasonably be implemented in
assembler (probably), and doing everything slice-wise should reduce the
overhead of the separate pack/unpack stages.

Just lazily tested.
The comment on AV_PIX_FMT_Y210LE seems to be wrong. It claims it's "like
YUYV422", bit it seems more like YVYU422, at last the way libswscale
input treats it. Maybe Intel pays its developers too much?
The repacker inner lop is probably rather inefficient. In theory we
could optimize it by reading the packed pixels as words, doing the
component reshuffling using compile time values etc., but I'd rather
keep the code size small. It's already bad enough that we have to
support 16 bit per component variants, just because this one Intel guy
couldn't keep it in his pants. In general, I can't be bothered to spend
time on optimizing it; I'm only doing this for fun (i.e. masochistic
obligation).

Instead of just picking the last tag that was encountered. The order of

This is probably wrong, and we should respect TargetTypeValue. But

Consider e.g. --aid=2 with a file that has only 1 track. Then it would
fall back to selecting track 1. Stop doing this. If no matching track is
found, this will not select any track now.
Note that the fingerprint stuff (track_layout_hash in the source)
prevents softens the impact of this change. Without the fingerprint,
playing a dual-audio file with the second track selected, and then a
single-audio file, would play the second file without audio. But the
fingerprint resets it due to differences in the track list.
Try to exhaustively document this and tricky interactions between the
other features. What a damn mess, I think it's simply cursed. Of course
it's still my fault.

Some time ago, properties and options were mostly unified. However, the
track selection properties/options semantics are incompatible to this
change. I'm still trying to handle the fallout.
There are two things that are in the way:
1. Track properties somehow return the runtime selection, not the option
value (all while properties are supposed to be aliases to options
with the same name).
2. The user's track options are not supposed to be changed without
interaction. If a track is auto-selected, the property should return
its ID, but the option value should remain at "auto". Only if the
user actually writes to the property the option should change. E.g.
playing e.g. an audio-only file and then a normal video file not play
the video file with --vid=no just because the audio file had no video
track.
In addition to each of them being in conflict with the property/option
unification, attempt to fix one of them breaks the other one.
Today, we're trying to fix parts of this and avoiding an unfortunate
case where you can get a conflicting option/property value, and where
trying to select a track does nothing if the track to select has the
same ID as the option value.
This breaks 2. from above in certain situations. See manpage additions.

Unfortunately, attached pictures (from tags etc.) are treated as video

This covers 8 and 16 bit packed RGB formats. It doesn't really help with
any actual use-cases, other than giving the finger to libswscale.
One problem is with different color depths. For example, rgb565 provides
1 bit more resolution to the green channel. zimg can only dither to a
uniform depth. I tried dithering to the highest depth and shifting away
1 bit for the lower channels, but that looked ugly (or I messed up
somewhere), so instead it dithers to the lowest depth, and adjusts the
value range if needed. Testing with bgr4_byte (extreme case with 1/2/1
depths), it looks more "grainy" (ordered dithering artifacts) than
libswscale, but it also looks cleaner and smoother. It doesn't have
libswscale's weird red-shift. So I call it a success.
Big endian formats need to be handled explicitly; the generic big endian
swapper code assumes byte-aligned components.
Unpacking is done with shifts and 3 LUTs. This is symmetric to the
packer. Using a generated palette might be better, but I preferred to
keep the symmetry, and not having to mess with a generated palette and
the pal8 code.
This uses FFmepg pixfmts constants directly. I would have preferred
keeping zimg completely separate. But neither do I want to add an IMGFMT
alias for every of these formats, nor do I want to extend our imgfmt
code such that it can provide a complete description of each packed RGB
format (similar to FFmpeg pixdesc).
It also appears that FFmpeg pixdesc as well as the FFmpeg pixfmt doxygen
have an error regarding RGB8: the R/B bit depths are swapped. libswscale
appears to be handling them differently. Not completely sure, as this is
the only packed format case with R/B havuing different depths (instead
of G, the middle component, where things are symmetric).

One of the extremely annoying dumb things in ffmpeg is that most pixel
formats are available as little endian and big endian variants. (The
sane way would be having native endian formats only.) Usually, most of
the real codecs use native formats only, while non-native formats are
used by fringe raw codecs only. But the PNG encoders and decoders
unfortunately use big endian formats, and since PNG it such a popular
format, this causes problems for us. In par |
