Dudemanguy a88fdfde0c command: add display-width/display-height property
For some reason, this never existed before. Add VOCTRL_GET_DISPLAY_RES
and use it to obtain the current display's resolution from each
vo/windowing backend if applicable. Users can then access the current
display resolution as display-width and display-height as per the client
api. Note that macOS/cocoa was not attempted in this commit since the
author has no clue how to write swift.

Dudemanguy b59eaf57fe wayland: unify frame/presentation callback code
Originally when presentation time was implemented, the frame callback
and presentation feedback functions were called in each rendering api's
separate backend (egl and vulkan). This meant that their respective
structs were basically copy and pasted across both files. Plus later
vo_wlshm started using frame callbacks too. Things got refactored a few
times and it turns out there's actually no need to have these things
separate anymore. The frame callback can just be initialized in
vo_wayland_init and then everything else will follow from there. Just
move all of this code to wayland_common and get rid of the duplication.

Sidenote: This means that vo_wlshm can actually receive presentation
feedback now. It's really simple to do so might as well. See the next
commit.

Dudemanguy dae6b1be96 Revert "wayland: conditionally commit surface on resize"
30dcfbc is a workaround for incorrect border sizes that could occur on
sway/wlroots in certain edge cases. This seemed harmless enough, but it
turns out that on mutter the extra wl_surface_commit somehow causes the
window always go to the top left of the screen after you leave
fullscreen. No idea why this occurs, but the original commit is a
workaround a sway bug and causing regressions for other users isn't
right despite the author being biased towards sway/wlroots.

This reverts commit 30dcfbc9cb.

Dudemanguy f5a094db04 vo_gpu: EGL: hack for alpha on different platforms
7fb972f fixed transparency on x11/EGL/Mesa but happened to also break it
for wayland and nvidia. Ideally on wayland, you should just be able to
pick the right EGLConfig that has alpha but this doesn't seem to work
because reasons. So just go back to setting the EGL_ALPHA_SIZE bit if
the user asks for alpha. Apparently this worked before for nvidia as
well. The hack is to just run an eglQueryString in the x11egl context.
If it picks up Mesa as the EGL_VENDOR, then force ctx->opts.want_alpha
to 0 and let pick_xrgba_config take care of the rest.

Dudemanguy b60545bdc6 wayland: update opaque region on runtime
Made possible with 00b9c81. 34b8adc let the wayland surface set an
opaque region depending on if alpha was set by the user or not. However,
there was no attempted detection for runtime changes and it is possible
(at least in wayland vulkan) to toggle the alpha on and off. So this
meant, we could be incorrectly signalling an opaque region if the user
happened to change the alpha. Additionally, add a helper function for
this and use it everywhere we want to set the opaque region.

Dudemanguy deaea70630 wayland: be less strict about when to render
efb0c5c changed the rendering logic of mpv on wayland and made it skip
rendering when it did not receive frame callback in time. The idea was
to skip rendering when the surface was hidden and be less wasteful. This
unfortunately had issues in certain instances where a frame callback
could be missed (but the window was still in view) due to imprecise
rendering (like the default audio video-sync mode). This would lead to
the video appearing to stutter since mpv would skip rendering in those
cases.

To account for this case, simply re-add an old heuristic for detecting
if a window is hidden or not since the goal is to simply not render when
a window is hidden. If the wait on the frame callback times out enough
times in a row, then we consider the window hidden and thus begin to
skip rendering then. The actual threshold to consider a surface as
hidden is completely arbitrary (greater than your monitor's refresh
rate), but it's safe enough since realistically you're not going to miss
60+ frame callbacks in a row unless the surface actually is hidden.
Fixes #8169.

Dudemanguy 34b8adc456 wayland: set an opaque region
Apparently a part of the wayland spec. A compositor may use a surface
that has set part of itself as opaque for various optimizations. For
mpv, we simply set the entire surface as opaque as long as the user has
not set alpha=yes (note: alpha is technically broken in the wayland EGL
backend at the time of this commit but oh well). wlshm is always opaque.
Fixes #8125.

Dudemanguy efb0c5c446 wayland: only render if we have frame callback
Back in the olden days, mpv's wayland backend was driven by the frame
callback. This had several issues and was removed in favor of the
current approach which allowed some advanced features (like
display-resample and presentation time) to actually work properly.
However as a consequence, it meant that mpv always rendered, even if the
surface was hidden. Wayland people consider this "wasteful" (and well
they aren't wrong). This commit aims to avoid wasteful rendering by
doing some additional checks in the swapchain. There's three main parts
to this.

1. Wayland EGL now uses an external swapchain (like the drm context).
Before we start a new frame, we check to see if we are waiting on a
callback from the compositor. If there is no wait, then go ahead and
proceed to render the frame, swap buffers, and then initiate
vo_wayland_wait_frame to poll (with a timeout) for the next potential
callback. If we are still waiting on callback from the compositor when
starting a new frame, then we simple skip rendering it entirely until
the surface comes back into view.

2. Wayland on vulkan has essentially the same approach although the
details are a little different. The ra_vk_ctx does not have support for
an external swapchain and although such a mechanism could theoretically
be added, it doesn't make much sense with libplacebo. Instead,
start_frame was added as a param and used to check for callback.

3. For wlshm, it's simply a matter of adding frame callback to it,
leveraging vo_wayland_wait_frame, and using the frame callback value to
whether or not to draw the image.

wm4 7fb972fd39 vo_gpu: EGL: fix transparency on X11/EGL/Mesa
Transparent windows on X11/EGL/native Mesa GL didn't work for various
reasons. From what I remember, the current code did work with nvidia at
least. Mesa has made attempts to fix this, but they never really made it
in.

But it turns out you can make EGL/Mesa list the EGLConfigs that use X11
RGBA visuals, and context_x11egl.c contains code that explicitly selects
them if alpha is requested (see pick_xrgba_config()).

The reason EGL/Mesa did not list them (and thus breaking transparency)
is because we requested a EGL_ALPHA_SIZE != 0 if alpha is requested. But
the transparent EGLConfigs use EGL_ALPHA_SIZE == 0. That's because EGL
doesn't actually support the concept of transparent windows; the alpha
size parameter is something else (memory rendering without FBOs or
something, I don't care enough to look up the real reasons).

This still won't work on Wayland. Every EGL backend needs platform
specific code. (Good job, EGL, such an awesome platform independent
standard.)

Dudemanguy 30dcfbc9cb wayland: conditionally commit surface on resize
It was possible for sway to get incorrectly sized borders if you resized
the mpv window in a creative manner (e.g. open a video in a non-floating
mode, set window scale to 2, then float it and witness wrong border
sizes). This is possibly a sway bug (Plasma doesn't have these border
issues at least), but there's a reasonable workaround for this.

The reason for the incorrect border size is because it is possible for
mpv to ignore the width/height from the toplevel listener and set its
own size. This new size can differ from what sway/wlroots believes the
size is which is what causes the sever side decorations to be drawn on
incorrect dimensions.

A simple trick is to just explicitly commit the surface after a resize
is performed. This is only done if mpv is not fullscreened or maximized
since we always obey the compositor widths/heights in those cases.
Sending the commit signals the compositor of the new change in the
surface and thus sway/wlroots updates its internal coordinates
appropriately and borders are no longer broken.

Dudemanguy 486516f723 wayland: don't rely on presentation discarded
When using presentation time, we have to be sure to update the ust when
no presentation events are received to make sure playback is still
smooth and in sync. Part of the recent presentation time refactor was to
use the presentation discarded event to signal that the window is
hidden. Evidently, this doesn't work the same everywhere for whatever
reason (drivers?? hardware??) and at least one user experienced issues
with playback getting out of sync since (presumably) the discarded event
didn't occur when hiding the window. Instead, let's just go back to the
old way of checking if the last_ust is equal to the ust value of the
last member in the wayland sync queue. Fixes #8010.

Dudemanguy e9cde72536 wayland: refactor presentation time
The motivation for this change was a segfault caused by e107342 which
has complicated reasons for occuring (i.e. I'm not 100% sure but I think
it is a really weird race). The major part of this commit is moving the
initialization of presentation listener to the frame_callback function.
Calling it in swap_buffers worked fine but in practice it meant a lot of
meaningless function calls if a window was hidden (the presentation
would just be immediately discarded). By calling it in frame_callback,
we ensure the listener is only created when it is possible to receive a
presentation event.

Of course calling the presentation listener in feedback_presented or
feedback_discarded was considered, but ultimately these events are too
slow. Receiving the ust/msc/sbc triplet here and then passing it to mpv
results in higher vsync judder since there is (likely) not enough time
before the next pageflip. By design, the frame callback is meant to give
us as much time as possible before the next repaint so calling it here
is probably optimal.

Additionally, we can make better use of the feedback_discarded event.
The wp_presentation_feedback should not be destroyed here. It will be
taken care of either when we get feedback again or when the player
quits. Instead what we can do is set a bool that tells wayland_sync_swap
to update itself based on mp_time delta. In practice, the result is not
any different than before, but it should be more understandable what is
going on now.

Of course, the segfault mentioned at the beginning is fixed with this as
well.

Dudemanguy 055a490cef wayland: use mp_time deltas for presentation time
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.

Niklas Haas 7e52e72746 vo_gpu: opengl: make sure to always clean up debug callbacks
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.

wm4 26f4f18c06 options: change option macros and all option declarations
Change all OPT_* macros such that they don't define the entire m_option
initializer, and instead expand only to a part of it, which sets certain
fields. This requires changing almost every option declaration, because
they all use these macros. A declaration now always starts with

   {"name", ...

followed by designated initializers only (possibly wrapped in macros).
The OPT_* macros now initialize the .offset and .type fields only,
sometimes also .priv and others.

I think this change makes the option macros less tricky. The old code
had to stuff everything into macro arguments (and attempted to allow
setting arbitrary fields by letting the user pass designated
initializers in the vararg parts). Some of this was made messy due to
C99 and C11 not allowing 0-sized varargs with ',' removal. It's also
possible that this change is pointless, other than cosmetic preferences.

Not too happy about some things. For example, the OPT_CHOICE()
indentation I applied looks a bit ugly.

Much of this change was done with regex search&replace, but some places
required manual editing. In particular, code in "obscure" areas (which I
didn't include in compilation) might be broken now.

In wayland_common.c the author of some option declarations confused the
flags parameter with the default value (though the default value was
also properly set below). I fixed this with this change.

It was still used in CDDA (--cdda-span) and a debug option for OpenGL

each sets the start/end values of the former span. Both were
undocumented somehow (normally we require all options to be documented),

Sven Kroeger fc8c1fcfb2 drm_prime: double free bug
This commit fixes a bug where handle for a framebuffer gets double
freed.
It seems to happen that the same prime fd gets two framebuffers.
As the prime fd is the same the resulting prime handle is also the
same.
This means one handle but 2 framebuffers and can lead to the following
chain:

1. The first framebuffer gets deleted the handle gets also freed via
the ioctl.

2. In startup phase not all 4 dumb buffers for overlay drawing
are set up. It can happen that the last dumb buffer gets the
handle we freed above.

3. The second framebuffer gets freed and the handle will be
freed again resulting that the 4's dumb buffer handle is not
backed by a buffer.

4. Drm prime continues to assign handles to its prime fds an
will lead to have this handle which was just freed to
reassign again but to an prime buffer.

5.Now the overlay should be drawn into dumb buffer 4 which
still has the same handle but is backed by the wrong buffer.
This leads to two different behaviors:

- MPV crashes as the drm prime buffers size als calculated
by the decoder output format. The overlay output format
differs and it takes more space. SO the size check
in kernel fails.

- MPV is continuing play. This happens when the decoders
allocates a bigger buffer than needed for the overlay.
For example overlay is Full HD and decoder output is 4k.
This leads to the behavior das the overlay wil be drawn
into the wrong buffer as its a drm prime buffer and results
in a flicker every fourth step.

dudemanguy b926f18938 wayland: remove wayland-frame-wait-offset option
This originally existed as a hack for weston. In certain scenarios, a
frame taking too long to render would cause vo_wayland_wait_frame to
timeout which would result in a ton of dropped frames. The naive
solution was to just to add a slight delay to the time value. If a
frame took too long, it would likely to fall under the timeout value and
all was well. This was exposed to the user since the default delay
(1000) was completely arbitrary.

However with presentation time, this doesn't appear to be neccesary.
Fresh frames that take longer than the display's refresh rate (16.666 ms
in most cases) behave well in Weston. In the other two main compositors
without presentation time (GNOME and Plasma), they also do not
experience any ill effects. It's better not to overcomplicate things, so
this "feature" can be removed now.

Philip Langdale eb852dc50c vo_gpu: hwdec_vdpau: remove direct_mode
As we are less and less interested in vpdpau, with nvdec and vaapi
being better choices in general on nvidia and AMD respectively, we
might consider removing direct_mode, where we bypass the vdpau
mixer and work directly with yuv textures. Normally, working with
yuv textures would be great, but vdpau built in an assumption that
all frames are delivered as separate fields, causing us to have
to re-interleave them.

nvidia then introduces a new OpenGL extension that can return the
yuv frames as frames, but we can't just unconditionally switch to
that as we'd want to keep supporting older hardware where the drivers
are no longer getting new features. The end result is that we
wouldn't be able to get rid of the old code paths.

Removing direct_mode means we always use the mixer, and work with
rgba frame textures. There are some theoretical limitations to
this, but in practice they probably don't matter much - unsupported
colourspaces don't matter because without 10bit decoding support,
we can't use them anyway, and apparently we're not doing separate
chroma scaling these days, so scaling the rbga doesn't really lose
anything (and the vdpau hq scaling option remains available).

wm4 e1586585b4 vo_gpu: opengl: make it work with EGL 1.4
This tries to deal with the crazy EGL situation. The summary is:

- using eglGetDisplay() with multiple windowing platforms doesn't really
  work, but Mesa had an awful hack for it
- this hack can be disabled at build time, and some distros sometimes
  accidentally or intentionally do so
- Mesa will probably eventually disable it by default
- we switched to eglGetPlatformDisplay(), but this requires EGL 1.5
- the very regrettable graphics company (also known as Nvidia) ships
  drivers (for old hardware I think) that are EGL 1.4 only
- that means even though we "require" EGL 1.5 and link against it, the
  runtime EGL may be 1.4
- trying to run mpv there crashes in the dynamic linker
- so we have to go through some more awful compatibility hacks

This commit tries to do it "properly", but using EGL 1.4 as base. The
plaform selection mechanism is a messy extension there, which got
elevated to core API in 1.5 (but OF COURSE in incompatible ways).

I'm not sure whether the EGL 1.5 code path (by parsing the EGL_VERSION)
is really needed, but if you ask me, it feels slightly saner not to rely
on an EGL 1.4 kludge forever. But maybe this is just an instance of
self-harm, since they will most likely never drop or not provide this
API.

Also, unlike before, we actually check the extension string for the
individual platform extensions, because who knows, some EGL
implementations might curse us if we pass unknown platform parameters.
(But actually, the more I think about this, the more bullshit it is.)

X11 and Wayland were the only ones trying to call eglGetPlatformDisplay,
so they're the only ones which are adjusted in this commit.

Unfortunately, correct function of this commit is unconfirmed. It's
possible that it crashes with the old drivers mentioned above.

Why didn't they solve it like this:

struct native_display {
    int platform_type;
    void *native_display;
};

Could have kept eglGetDisplay() without all the obnoxious extension BS.

wm4 cc746c9508 vo_gpu: x11egl: cleanup EGL correctly
...probably.

The EGL backend had a strange problem: when recreating the window, EGL
surface creation sometimes mysteriously failed. For example, keeping the
"_" key down (cycles video by default) destroys and recreates the window
in rapid succession, which will often enough show the "Could not create
EGL surface!" message.

This was puzzling because due to mpv's architecture, the X11 Window and
even the X11 Display were fully destroyed, the thread on which they ran
was destroyed, and then everything was recreated. There shouldn't have
been any state that could make subsequent EGL initialization fail.

It turns out mpv forgot to free EGLSurfaces in the x11 code. EGL is a
pretty crazy API (full of thread local and global state with weird
lifetime requirements), and for example it seems EGLDisplay cannot be
explicitly released, but apparently implicitly dies when the native
display is closed (at least EGL 1.5 claims eglTerminate() does _not_
invalidate the display, only certain objects linked to it). It appears
that Mesa still referenced at least EGLSurface in some form, and either
some pointer or some X11 ID was dangling, and when it randomly matched
when eglCreateWindowSurface() was called, it failed.

Fix this by calling eglTerminate(), which supposedly destroys (or rather
unreferences) contexts and surfaces created from the display (but
absurdly not the display itself).

Now why can't you just destroy the display? If it's implicitly
invalidated, why can't it just call eglTerminate() implicitly when this
happens? Did Mesa do something wrong when they somehow didn't
automatically remove the dangling object (so I could claim not to be
responsible for the bug)? Who the fuck knows, and I'm too tired to
figure this out (both because it's late, and because I'm tired of this
EGL crap API).

Still not sure if the code is correct now. I think EGL was designed to
maximize implementation and API-use complications. How else could you
possibly come up with something like the EGLDisplay life cycle? Or am I
just making a fuss? Anyway, fuck EGL, fuck computers, fuck technology.

Anton Kindestam d5cabf7348 drm: avoid division by 0 in drm_pflip_cb with bad drivers
Seems like some drivers only increment msc every other page flip when
running in interlaced mode (I'm looking at you nouveau). I.e. it seems
to be incremented at the frame rate, rather than the field rate.
Obviously we can't work with this, so shame the driver and bail.

On intel this isn't an issue, as msc is incremented at field rate
there.

This means presentation feedback won't work correctly in interlaced
modes with those drivers, but who in their right mind uses an
interlaced mode these days, anyway?

wm4 fa9a1ff0a0 vo_gpu: opengl: add hack for ancient Mesa/GLX
glx.h recursively includes gl.h, and there is no way to prevent this.
Old Mesa defines some GL symbols, but not all which mpv needs. In
particular, one user who was too lazy to update his ancient Ubuntu and
preferred to bother us with obscure bug reports, had Mesa headers which
did not define GL 3.2, so GLsync was not defined.

All in all I still think the idea of providing the GL API definitions
ourselves was a good idea; just GLX should have been isolated better.
But isolating GLX now is too much effort.

Not sure why I'm bothering with this at all.

wm4 053297b1ca vo_gpu: opengl: do not free "GL" sub-allocations
This function always expects the GL struct pointer to be a talloc
allocation. So far so bad. But the terrible thing is that _lots_ of code
in mpv didn't quite get this (including the code which introduced the
way it is used this way). For example, in context_glx.c you see this:

struct priv {
    GL gl;
    ...

GL is not a talloc allocation, but since it's at the start of a talloc
allocation, it works anyway. So far so bad. But the really terrible
thing is that mpgl_load_functions2() calls talloc_free_children() on the
GL pointer, which means that all of priv's. This would be unintentional
and could create dangling pointers. And this happens at the about 1
dozen of callers. I'm amazed it didn't broke yet anywhere.

Removing this anti-pattern with making GL "implicitly" a talloc
allocation would be too much effort at this point. So just manually free
the only allocation that the function attached to GL.

Dudemanguy 0d8a6c6984 wayland: use eglGetPlatformDisplay()
See aacc194. The same logic all applies to Wayland. In fact, we already
require EGL 1.5 for wayland anyway, so it's better to do it right.

wm4 aacc1942fb x11: require EGL 1.5 and use eglGetPlatformDisplay()
eglGetPlatform() is a broken API, since it takes a windowing specific
argument, yet is supposed to work for multiple APIs at the same time. On
Linux, it can take both a X11 "Display" and a "wl_display". Obviously
there is no way to specify what kind of display the argument is (it's
just a void*).

Mesa has _eglNativePlatformDetectNativeDisplay, which does funny stuff
to try to guess the display type, including trying to call mincore() to
determine whether the pointer can be accessed at all. I guess this
recently accidentally broke (as a bug), but on the other hand, maybe
it's time to do this properly.

The fix is using eglGetPlaformDisplay(). This requires EGL 1.5, plus
Mesa needs to support the associated platform extension
(EGL_KHR_platform_x11).

Since I see no reasonable way to do this in a compatible way, just
require that EGL 1.5 is available. The problem is that EGL 1.4 seems to
require you to create a display to query EGL version and extension, and
you have a chicken-and-egg problem. It's very stupid. Maybe you could
jump through some more hoops to get something compatible, but fuck that.
Users on "too old" Mesa will fall back to GLX (which we keep around for
a regrettable company known by the name of Nvidia).

I think Wayland and GBM should do the same. They're sufficiently
bleeding-edge that you can expect them to have EGL 1.5. On the other
hand, the cursed RPI code will have to stay with a eglGetDisplay().

Speculative fix for #7154.

(Rant about EGL follows. Actually I deleted it.)

wm4 1c8d2246bf vo_gpu: vdpau actually works under EGL
The use of glXGetCurrentDisplay() restricted this to the GLX backend.
But actually it works under EGL as well. Removing the GLX-specific call
and using the general mpv-internal method to get the X "Display" makes
it work in mpv.

I didn't know this. Nvidia didn't list this as extension in the EGL
context when I still used their GPUs.

Note that this might in theory break use of vdpau in some libmpv clients
using the render API. But only if MPV_RENDER_PARAM_X11_DISPLAY is not
used, and they relied on mpv using glXGetCurrentDisplay(). EGL does not
provide such an API, and hwdec_vaapi.c also uses what hwdec_vdpau.c uses
now. Considering that vaapi is preferable these days, it's not bad at
all if these clients get "broken". They can be easily fixed by passing
the display to mpv correctly.

wm4 3e660f6164 vo_gpu: opengl: add support for IMGFMT_RGB30
This integrates it as "special" format, with no alpha component, as the
equivalent IMGFMT_RGB30 isn't meant to contain any.

Nothing can produce this format in the video chain yet, so the next
commits are needed to make this actually work.

Dudemanguy911 9dead2b932 wayland: fix presentation time
There's 2 stupid things here that need to be fixed. First of all,
vulkan wasn't actually using presentation time because somehow the
get_vsync function in context.c disappeared. Secondly, if the mpv window
was hidden it was updating the ust time based on the refresh_usec but
really it should simply just not feed any information to the vsync info
structure. So this adds some logic to assume whether or not a window is
hidden.

wm4 c75e0320f6 vo_gpu: hwdec_d3d11egl: add missing P010 format to supported list
This was obviously missing from the recent commit, which probably broke
10 bit decoding. The original commit didn't test this for lack of
working hardware; this commit isn't tested either.

wm4 a1c7d61393 vo_gpu: hwdec_d3d11egl: adapt to newer ANGLE API
2 years ago, ANGLE removed the old NV12-specific extension, and added
a new one that supports a number of formats, including P010. Actually
they just renamed it and removed their initial annoying and obvious
design error (bravo, Google).

Since it broke 2 years ago, nobody should give a shit about this code,
and it should just be removed. But for some reason I still dived the
shit-tank (Windows development).

I guess Intel code monkeys can't write drivers (or maybe the issue is
because we're doing zero-copy, which probably maybe is not actually
allowed by D3D11 due to array textures, see --d3d11va-zero-copy), so
the P010 path is completely untested. It doesn't work, I'll delete all
this ANGLE hwdec code.

dudemanguy ea4685b233 wayland: use callback flag + poll for buffer swap
The old way of using wayland in mpv relied on an external renderloop for
semi-accurate timings. This had multiple issues though. Display sync
would break whenever the window was hidden (since the frame callback
stopped being executed) which was really annoying. Also the entire
external renderloop logic was kind of fragile and didn't play well with
mpv's internal structure (i.e. using presentation time in that old
paradigm breaks stats.lua).

Basically the problem is that swap buffers blocks on wayland which is
crap whenever you hide the mpv window since it looks up the entire
player. So you have to make swap buffers not block, but this has a
different problem. Timings will be terrible if you use the unblocked
swap buffers call.

Based on some discussion in #wayland, the trick here is relatively
simple and works well enough for our purposes. Instead we basically
build a way to block with a timeout in the wayland buffer swap
functions.

A bool is set in the frame callback function that indicates whether or
not mpv is waiting for a frame to be displayed. In the actual buffer
swap function, we enter into a while loop waiting for this flag to be
set. At the same time, the wl_display is polled to block the thread and
wakeup if it receives any events from the compositor. This loop only
breaks if enough time has passed or if the frame callback bool is
received.

In the near future, it is better to set whether or not frame a frame has
been displayed in the presentation feedback. However as a first pass,
doing it in the frame callback is more than good enough.

The "downside" is that we render frames that aren't actually shown on
screen when the player is hidden (it seems like wayland people don't
like that). But who cares. Accurate timings are way more important. It's
probably not too hard to add that behavior back in the player though.

dudemanguy fd7aff7a9d wayland opengl: actually call uninit if init fails
This is the proper fix to the memory leak @wm4 pointed out. It turns out
that when you autoprobe opengl and vo_wayland_init returns false,
vo_wayland_uninit is never actually executed. So you have a leftover
pointer. The vulkan context does this correctly which was why my old,
dumb "fix" broke it.
