Before this commit, all VOs had to toggle the option flag themselves,
now command.c does it.
I can't really comprehend why it required every VO to do this manually.
Maybe it was for rejecting the property/option change if the VO didn't
support a specific capability. But then it could have checked the VOCTRL
result. In any case, I don't care, and successfully changing the
property without doing anything (With some VOs) is fine too. Many things
work this way now, and it's simpler overall.
This change will be useful for cleaning up VO option handling.

Just a minor refactor along the planned option change. This commit will
make it easier to update (i.e. copy) the VO options without copying
_all_ options. For now, behavior should be equivalent, though.
(The VO options were put into a separate struct quite early - when all
global variables were removed from the source code. It wasn't clear
whether the separate struct would have any actual purpose, but it seems
it will now. Awesome, huh.)

It seems like many GL implementations (including Mesa) choke on this,
while others are fine. We still think that this use of the GL API is
allowed by the standard (at least in the Mesa case), so to reduce
confusion, explicitly check the "controversial" calls, and use an
appropriate error message.

If wait_us is >0 and <500, the wait time gets rounded down 0,
effectively turning this into busy waiting. Round it up instead.

Shouldn't matter. Was pointed out by someone. The change should help
avoiding extra unneeded wakeups on the VO thread.

Because VOCTRL_CHECK_EVENTS is processed asynchronously (as of 088a007,)
the GUI thread no longer gets regular wakeups, so the old check that
made sure the video window matched the parent window's size in --wid
embedding mode did not run very often. This made --wid embedding not
very usable.
Instead of polling for window size changes, use Windows hooks to react
to them when they happen. When the parent window is owned by the same
process as the video window, use a WH_CALLWNDPROC hook. When the parent
window is not owned by the same process, WinEvents must be used, which
are not as smooth, but still work for this purpose.
Since neither SetWindowsHookEx nor SetWinEventHook take a context
parameter to send data to the hook function, the hook functions must
find the child window by its class instead, so there are a few changes
to ensure this is fast and the class is unique.
This also fixes up the logic to handle window destruction. When a parent
window is destroyed, its children are also destroyed, so this gives us a
way to react to parent window destruction without polling.

On some systems DirectComposition might behave poorly. Add an opengl
suboption flag 'dcomposition' (default=yes) which can disable it.

If the video has the same size as the screen, starting with --fs and
then leaving fullscreen doesn't actually leave fullscreen.
The reason is that mpv tries to restore the previous window size if
necessary (otherwise, you'd end up with a Window of nearly the same size
as the screen with some WMs). It will typically restore with the
rectangle set exactly to the screen if no other position or size is
forced. This triggers pre-EWMH fullscreen mode, which WMs detect using
various heuristics.
Apparently we triggered this with mutter (but strangely no other WMs).
It's possible that pre-EWMH fullscreen mode actually requires removing
decorations, and mutter either ignores this. But this is speculation and
I haven't checked.
Work this around by reducing the requested size by 1 pixel if it
happens.
This was observed with mutter 3.18.2.
Fixes #2072.

This should actually be rather safe - we already check whether the
estimated value jitters less than the (possibly untrustworthy) nominal
one. Remove a "safety" check that disabled this code for small
deviations, and make it trigger sooner into playback. Also lower the log
level of messages about using the estimated display FPS down to verbose.
Normally there's another mechanism for smoothing out minor estimation
differences, but that is not good enough here.
This possibly improves behavior as reported in #3433, which can be
reproduced with --vo=null:fps=48.426 --display-fps=48 (though it doesn't
consider the jitter introduced by a real VO).

Doing this required synchronizing with the VO thread, which could lead
to audio dropouts if the VO was frozen (which can happen in practice if
e.g. an opengl_cb user is not doing what the API demands).
Add a way to send asynchronous VOCTRLs, and use that for the playback
state. In theory, it would be better to make this status update a
several function and to "merge" several queued update, but that would be
slightly more effort/code, and the update is so infrequent that the
merging would never happen anyway.
The change to vo_destroy() is to make sure all queued asynchronous
reuqests are finished before making the vo_thread exit.
Even though it's only used on MS Windows, it's run on any platform with
any VO, which makes this worse.

run_control() dereferences an uint32_t as int. Whether this is allowed
depends on what uint32_t is typedefed to (dereferencing an unsigned int
as int should be fine). Fix it by always using int. The uint32_t type
never really made sense.

In display-sync mode, the very first video frame is idiotically fully
timed, even though audio has not been synced yet at this point, and the
video frame is more like a "preview" frame. But since it's fully timed,
an underflow is detected if audio takes longer than the display time of
the frame (we send the second frame only after audio is done).
The timing code will try to compensate for the determined desync, but it
really shouldn't. So explicitly discard the timing info in this specific
case. On the other hand, if the first frame still hasn't finished
display, we can pretend everything is ok.
This is a hack - ideally, we either would send a frame without timing
info (and then send it again or so when playback starts properly), or we
would add real pause support to the VO, and pause it during syncing.

VOCTRL_CHECK_EVENTS is called on every frame. This is by design, and is
supposed to check the event queue of the windowing API.
With the decoupled GUI thread in w32_common.c this doesn't make too much
sense, and the purpose of VOCTRL_CHECK_EVENTS is really reduced to
checking event flags. Even worse, waiting on the GUI thread can
interfere with playback, since win32 sometimes blocks the event loop
(e.g. clicking the window title bar).
Change the code such that we really only query the event flags. Use
atomics to avoid having to add a new mutex. (We assume we always have
real atomics available. The build system doesn't check this properly,
and it could fall back to dummy atomics, which are not atomic.)
Should help with #3393. Doesn't help if the core happens to send a
synchronous request, most commonly via VOCTRL_SET_CURSOR_VISIBILITY or
VOCTRL_UPDATE_PLAYBACK_STATE.

Otherwise opengl/video.c would confusingly complain about a wrong
version, which in this case makes no sense.

Prevents segfaults when a fullscreen switch is issued before fully
initializing the VO.
Doesn't change anything since the schedule_resize is only there to
resize in case the image size switches, which happens long after init.

It makes more sense to completely abstract this scaling inside the
backend so that internally the player only works with real actual
drawn pixels.

The problem was that when in fullscreen, switching between images did
not issue a resize event, causing none of the images to be rendered
correctly.
This fixes the problem by issuing a resize event with the screen width
and height.
This commit also moves the zeroing of the events field to when it gets
retrieved by mpv rather than randomly after a resize in the vo/backend
code.

ssurface_handle_configure()'s width and height are just hints given by
the compositor, the application's free to not respect those strictly and
to compensate for e.g. aspect ratio.
This prevents crazy scenarios in which pictures with portrait aspect
ratios have a huge black area to make them 16:9 or whatever the
compositor feels like.

With X11 it was usually left up to the window manager to prevent huge
windows from being out of range, but no Wayland compositor will do
this right now.
Hugely improves usability when using mpv as an image viewer.

This requires changing the pixel upload alignment because the odd sizes
might not be aligned to multiples of 4.
Anyway, the restriction has no real benefit and the sizes in between 32
and 64 might be worth using, so just drop it.

Following testing after ebe798a, this is a more than sufficient size to
cover our use case.
The old default was a drop of about 58 dB PSNR using the old code, and
this new default is about 65 dB PSNR, so it's actually an improvement
despite resulting in a smaller size.
There was no outlier whatsoever when comparing sizes around the 64
neighbourhood (with every step corresponding to a PSNR drop of about
0.07 dB), so I picked this since it's a power of two and requires no
change to the current 3dlut-size parsing logic.
I also tested smaller sizes such as 32x32x32 which performed almost as
well on colorful samples, but this results in noticeable black boost in
the dark regions, which is pretty undesirable. Therefore, we should
avoid going much further below 64x64x64.
Either way, this new size is so fast to compute that the 3dlut cache is
almost useless on my end. In fact, it might even be slower to load the
profile from the cache than to recompute it from scratch. (For caches on
a disk. For cache on a tmpfs, it makes no difference)

It seems vo_x11_check_events() was supposed to return the currently
flagged events and reset them. But there are many places where
vo_x11_check_events() is called without checking its return value. This
could lead to forgotten events.
Change the code such that they can't get lost.

This code had the exact same texture indexing bug that the original
scaler code had before the introduction of the LUT_POS macro to fix it.
We can re-use this same macro here, and the performance drop is
virtually entirely negligible. The benefit is greatly improved LUT
accuracy as the 3DLUT size decreases - in particular, the old LUT
started introducing more and more black crush the lower your LUT size is
(because the error was essentially an over-contrast bias, with a
magnitude linearly related to the lut size).
The new code improves black stability as the LUT size decreases, and
only at very low values (16 and below) do black levels start noticeably
getting affected (due to crude linearization of the nonlinear response
curve).
The default value of 3dlut-size is definitely generous enough for this
to make no difference out of the box, but it also causes no performance
drop at all on my machine so I see no harm in improving the logic.
Furthermore, this means we could easily decrease the default 3dlut size
in a future commit, perhaps even down to 64x64x64 as a default. (But
more testing is warranted here)

Both backends have code to close each FD of their wakeup_pipe array.
This array is default-initialized with 0, which means if the backends
exit before the wakeup pipe is created (e.g. when probing), they would
close FD 0.
Initialize the FDs with -1. Then we call close(-1) in these situations,
which is perfectly allowed and has no bad consequences.

This fits natively into the vo/backend and allows to simplify the
polling code.
One new change is the fact that surface_handle_enter flags VO_EVENT_WIN_STATE
and VO_EVENT_RESIZE instead of only VO_EVENT_WIN_STATE. Before this, the code
hackily relied on the timeout and the loop in the wait_frame function to track
and set the scaling factor. Instead, this triggers mpv to run a schedule_resize
and adjust the new VO output dimensions immediately. This is also more accurate
since surface_handle_enter() gets called when a surface is created, moved and
resized, which is exactly what the rest of the player might be interested in.

This uses GLSL mix() instead of going through an indirect texture
access. Easy to implement and might require less resources on some
devices, since the oversample code was already essentially just a
special case of this.
Could be made the new default (as per issue #2685), but that should be
done in a separate commit.

Until now, this has been either handled over vo.event_fd (which should
go away), or by putting event handling on a separate thread. The
backends which do the latter do it for a reason and won't need this, but
X11 and Wayland will, in order to get rid of event_fd.

There's no need to call wl_display_flush() since all the client-side
buffered data has already been flushed prior to polling the fd.
Instead only check for POLLIN and the usual ERR+HUP.

Don't just cause vo_opengl to update the ICC profile every time the
window is moved. Instead, explicitly check if the screen was changed.

In theory, mp_image_params with hw_subfmt set to non-0 if imgfmt is not
a hwaccel format is invalid. (It worked fine because nothing checks this
yet.)

The hw_subfmt field roughly corresponds to the field
AVHWFramesContext.sw_format in ffmpeg. The ffmpeg one is of the type
AVPixelFormat (instead of the underlying hardware format), so it's a
good idea to switch to this too for preparation.
Now the hw_subfmt field is an mp_imgfmt instead of an opaque/API-
specific number. VDPAU and Direct3D11 already used mp_imgfmt, but
Videotoolbox and VAAPI had to be switched.
One somewhat user-visible change is that the verbose log will now always
show the hw_subfmt as image format, instead of as nonsensical number.
(In the end it would be good if we could switch to AVHWFramesContext
completely, but the upstream API is incomplete and doesn't cover
Direct3D11 and Videotoolbox.)

This should get mpv working on Windows 7 machines without hardware
accelerated graphics adapters. It already worked on Windows 8 and up
because those systems would silently fall back to WARP if there was no
graphics hardware installed.
The normal MPGL_CAP_SW flag is not set, so unlike other opengl backends,
this will choose a software adapter even if opengl:sw is not specified.
The reason for this is, unlike on Linux, where vo_xv and vo_x11 can be
used, mpv on Windows does not have any VO to fall back on when hardware
acceleration isn't available, so if software adapters are rejected, the
user won't see any video output when using the default settings. WARP
seems to perform quite well, so it should be used in this case.

These mostly happen in situations where the correct behavior is
relatively new and not found in the wild (therefore not worth
implementing) and/or extremely complicated (and thus not worth worrying
about the potential edge cases and UI changes).
Still, it's best to document these where they happen to guide the poor
souls maintaining these files in the future.

This uses eglPostSubBufferNV to trigger ANGLE to check the window size
and update the size of the swapchain to match, which is recommended
here: https://groups.google.com/d/msg/angleproject/RvyVkjRCQGU/gfKfT64IAgAJ
With the D3D11 backend, using eglPostSubBufferNV with a 0-sized update
region will even skip the Present() call, meaning it won't block for a
vsync period. Hopefully ANGLE will have a less hacky way of doing this
in future. See the relevant ANGLE issue: http://anglebug.com/1438

This can for example happen with vo_opengl_cb, if it is used with a GL
implementation that does not supports FBOs. (mpv itself should never
attempt to use FBOs if they're not available.)
Without this check it would trigger an assert() in our dummy
glBindFramebuffer wrapper.
Suspected cause of #3308, although it's still unlikely.
