Turns out libplacebo uses unrotated target crop in relation to source.
Use dst rect from VO, instead of extracting it from pl_frame, to avoid
another unrotating operation.
Fixes: a9354b36ca
Fixes the issue described in https://github.com/mpv-player/mpv/issues/11862
for SDR files for non-d3d11 gpu-api. We currently don't have a smarter
way to get the real on-the-wire bpc for other APIs, so this is the best
that can be done.
Upstream ASS specification says that all subtitles should be rendered
with color primaries and transfer matching their associated video. But
as expected after further discussion the decision has been made to
fallback to SDR mode in case of HDR video.

The VO generic code tries to be helpful and resets this after
each reconfig. However for the simpler VOs the target params
are constant after a reconfig or even for the entire lifetime.
So it's clearly better to let the VO decide.
This also allows the VO to use a static buffer instead.
It seems that GLX requires us to explicitly set opts.want alpha before
ra_ctx_create is called. b7fd232524
rearranged the function calls in a way made this not work. Fix this by
rearranging it again so the value is set before ra_ctx is created.
The --alpha option currently covers two related but different concepts:
whether or not to ignore the alpha component and possibly blending it
with a background. Because of the way the option currently works, it is
impossible to have a transparent window (which requires setting
--alpha=yes) while blending it with the background at the same time. To
solve this, let's rework it so it it superseded by the background
option.
--background controls what kind of background to set for the image if
possible. It can be blended with the set background color, with tiles,
or not blended at all (the last one is still broken on X11/mesa except
for GLX, *sigh*). In this new paradigm, --alpha=no has no real purpose
because you can simply set the background to color and whatever color
you want for exactly the same effect. So the option is removed. Instead,
the hint set by windowing backends (i.e. setting
ra_ctx->opts.want_alpha) can by done with the --background option.
As an aside, the colors in vo_gpu are currently bugged due to not
pre-multiplying the alpha and it seems no one ever noticed. The next
commit fixes that. vo_gpu_next support happens latter since it requires
new things from libplacebo.
Fixes#9615.
Currently this was being duplicated on init and on runtime updates
between both VOs. Since the conditions for setting this will get more
complicated in the future commits, it's better to just handle it in one
place. We could combine the vo_gpu and vo_gpu_next handling into one
single function but vo_gpu_next has an additional condition for
determining alpha that vo_gpu_does not, so we'll leave these separate
for simplicity. Also this technically fixes a memory leak where gl_opts
weren't being freed.
The purpose of osdep/io is to provide a wrapper for POSIX I/O functions
on Windows. The last 2 functions are utility functions which don't serve
this purpose.
Move them to a separate file.
Since 03cf150ff3, the only purpose of this
VOCTRL was to signal a redraw to the vo. It actualy could have been
removed in 531868fe0d, but this was
missed. The UPDATE_VIDEO flag is better anyway because it allows us to
handle a wide variety of options scattered around that require the VO to
update itself and redraw. We can remove both of the custom callbacks in
vo.c and only leave the VOCTRL_VO_OPTS_CHANGED one. Additionally, that
commit also introduced vo_set_want_redraw, but this is redundant and not
needed. The VOs that use VOCTRL_UPDATE_RENDER_OPTS already set
vo->want_redraw, and those are the only VOs where these options are
relevant in the first place. So we can remove this as well and just let
the big callback in player/command do everything.
Previously, libplacebo would fail to render the image since mpv was
feeding it bogus bitmaps with 0 width/height. An easy way to encounter
this would be to set sub-scale to 0 with bitmap/image subs.
Save the cache to separate files to avoid loading/saving a huge combined
libplacebo.cache. This approach allows the saving of only new cache
objects and avoids resaving the entire cache, especially even if only a
tiny change was made.
This commit improves the cold start time of mpv and avoids saving data
when it's not necessary.
Number of changes were made:
- each cached object is saved in its own file
- cache files are prefixed with the name of cached object
- cache directory is cleaned on each uninit
- the least recently used cache files are removed if cumulative cache
size is above limit
- files used in the recent 24 hours are not removed to allow changes
to mpv.conf without worrying about the cache being removed during
experimentation
- shader cache size limit is set to 128 MiB
- icc cache size limit is set to 1.5 GiB
- cache objects are loaded/saved as needed
This commit eliminates the runtime performance penalty associated with
the size cache. While we continue to maintain the cache limit to prevent
retaining stale objects, mpv now only loads a small subset of files that
are currently required for playback, instead of loading all files.
This mostly is added to resolve player command synchronization with VO
thread discussed in 477a0f83.
The current uses does not necessarily need this as they are all managed
by playloop. But for future use with other params that will be handy.
Those params are mostly to observe current state of VO and does not
necessarly need to be locked along with frame drawing, that changes the
params once at the end.
Up to 2x playback rate is the most we can offer currently. Should work
fine for most kernels with radius <= 2.
This avoids limitation of hwdecs number of frames in-flight.
Fixes: #12927
These are less likely to be modified from run to run, and with the
avoidance of redundant re-saving we can get away with a larger size.
This is enough to save 10 3DLUTs at typical sizes.
I have no idea why this code is such a convoluted mess of options and
possibilities. First of all, why is dumping both caches to a single file
even a supported use case? Why is the cache path generated multiple
times, once for saving and once for loading, instead of just generated
once and stored? Why even create a pl_cache if you're not going to
save/load it? Why so much code duplication?
I don't know. But I rewrote it in a way that makes far more sense to me.
This change prevents unwanted adjustments. Generally, screenshots
shouldn't invoke pl_queue_update, as this action could cull the already
mapped frames in the queue.
If !display_synced, some values may not be correct or zeroed. Therefore,
it makes no sense to interpolate in this case.
For a non-moving frame, we always want to show an uninterpolated frame.
libplacebo requires additional frames when VPS is lower than FPS and
anti-aliasing is enabled. Supports up to a 1/4 ratio. VO has a limit of
10 frames, so in practice, not many more can fit.
Note that the internal libplacebo mixing limit is 16 frames.
