I have to say this in PR reviews all the time, so maybe I should make i
explicit. In too many words of course, many, many, too many words which
nobody will read, I get it, now shut up. Sneak in some subtle or not so
subtle comments about how I think that github is ruining code quality.

mp.set_osd_ass() (which was undocumented, or in other words, was not
supposed to be used by external scripts) used to do change detection in
the mpv C code. If the resolution or payload did not change, it was not
re-rendered on the lower levels.
Apparently this made some people sad, so fix it. (But only after I told
them to fuck off.) (Well I didn't put it this way, but still.)

For some reason this was never done? Looking through the code, it was
never the case that the frame cache was hit for still frames. I have no
idea why not. It makes a lot of sense to do so.
Notably, this massively improves the performance of updating the OSC
when viewing e.g. large still images, or while paused. (Tested on a
4000x8000 image, the OSC now responds smoothly to user input)

The header probing hacks were previously all broken. They only worked
the first time the archive file was open. Since subsequent opens (on
seek) occured in the middle of the source stream rather than at the
beginning, the stream_read_peek calls meant to retrieve the headers were
instead returning random bytes in the middle of the file.
Perhaps the worst manifestation of this was when seeking within a
multi-volume .rar archive with the "legacy" file naming pattern. If the
seek required a reopen, the fact that the archive was multi-volume would
be forgotten and the file would appear truncated terminating playback.
To solve this, only perform the header probling the first time the
archive is opened. Save the results and reuse them on subsequent
reopens. Put this in a wrapper so this is transparent to
demux_libarchive.

Making OSD/subtitle bitmaps refcounted was planend a longer time ago,
e.g. the sub_bitmaps.packed field (which refcounts the subtitle bitmap
data) was added in 2016. But nothing benefited much from it, because
struct sub_bitmaps was usually stack allocated, and there was this weird
callback stuff through osd_draw().
Make it possible to get actually refcounted subtitle bitmaps on the OSD
API level. For this, we just copy all subtitle data other than the
bitmaps with sub_bitmaps_copy(). At first, I had planned some fancy
refcount shit, but when that was a big mess and hard to debug and just
boiled to emulating malloc(), I made it a full allocation+copy. This
affects mostly the parts array. With crazy ASS subtitles, this parts
array can get pretty big (thousands of elements or more), in which case
the extra alloc/copy could become performance relevant. But then again
this is just pure bullshit, and I see no need to care. In practice, this
extra work most likely gets drowned out by libass murdering a single
core (while mpv is waiting for it) anyway. So fuck it.
I just wanted this so draw_bmp.c requires only a single call to render
everything. VOs also can benefit from this, because the weird callback
shit isn't necessary anymore (simpler code), but I haven't done anything
about it yet. In general I'd hope this will work towards simplifying the
OSD layer, which is prerequisite for making actual further improvements.
I haven't tested some cases such as the "overlay-add" command. Maybe it
crashes now? Who knows, who cares.
In addition, it might be worthwhile to reduce the code duplication
between all the things that output subtitle bitmaps (with repacking,
image allocation, etc.), but that's orthogonal.

Only _writes_ are aligned, so the assumption doesn't work for reads. But
it's easy to fix by rounding down x0 to the next byte boundary. Writing
pixels outside of the read area is allowed, and we don't go out of
buffer bounds.
Patch by anon32, permission to do anything with it.

This is mostly for testing. It adds passing through the metadata through
the video chain. The metadata can be manipulated with vf_format. Support
for zimg alpha conversion (if built with zimg after it gained alpha
support) is implemented. Support premultiplied input in vo_gpu.
Some things still seem to be buggy.

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.

e1e714ccc introduced a regression here when unloading a track (e.g. on

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

I'd like to use this opportunity to complain once more about the
existence of these terrible pixel formats.
