Also replace the weights calculations for 8/12/16 with the generic
weight function definition macro. (The weights 2/4/6 follow slightly
different rules.)
This was required by vf_pp, which was just removed.
vf_dlopen has this stuff in its API. This API is considered stable, so
the related fields are not removed from it. But the fields are always 0
now, so there's no point in keeping the example program around.
vf_pullup.c did some extremely awkward passthrough of this information,
but didn't actually use it.
This is an ancient filter, and we assume it's not useful anymore.
If you really want this, it's still available in libavfilter (e.g. via
--vf=lavfi=[pp...]). The disadvantage is that mpv doesn't pass through
QP information to libavfilter. (This was probably the reason vf_pp still
was part of mpv - it was slightly easier to pass QP internally.)
This wasn't done before because there was no advantage in "abstracting"
it. This changed, and putting this into its own files is better than
messing it into gl_common.c/h.
Same as with the previous commits.
In theory, vdpau/x11 GL interop doesn't assume GLX. It could use EGL as
well. But since it's always GLX in practice, so we're fine with this.
Remove the gl_hwdec.mpgl field - it's unused now.
Basically, don't access the vo field.
There's also no reason anymore to access MPGLContext. We still need to
access loaded GL functions though, so add a field for that to gl_hwdec.
Untested.
Always set the viewport on entry. The way the viewport is tracked is a
bit complicated in my opinion, and in fact it doesn't even reduce the
number of GL calls. Setting it on entry is actually redundant if video
covers the screen fully, because the handle_pass() unconditionally sets
it anyway, but avoiding it would complicate the cases gl->Clear() is
actually needed.
Add a fbo argument to gl_video_render_frame(). This allows you to render
into a FBO rather than the default framebuffer. It will be useful for
providing an API to render on an external GL context. (If that will
actually be added.)
Seems like a waste not to print this.
Anyone with enough technical knowledge to have use for the exact error
can map the number back to the GL symbol, so don't bother to convert it
to a symbol.
All of these are already the defaults.
One exception is glDepthMask(), which is enabled by default. But if the
framebuffer has no depth buffer anyway, it shouldn't make a difference.
libxkbcommon keysyms are the same as X11 keysyms (sans prefix),
so I simply copied the missing subsection from x11_common.c.

MS Windows doesn't allow windows larger than the screen, so we include
a hack to make the window smaller. This hack recenters the window (what
else would it do?).
It didn't account for the virtual offset of the current screen, and it
was reported that it forces the window to the first screen.
Should fix#1292.
I suspect this is what is happening in github issue #1265 (at least
partially).
If D3DFMT_A8 is not available, fall back to RGBA. This is less efficient
in general, so we normally want to avoid it.
...because everything is terrible.
strerror() is not documented as having to be thread-safe by POSIX and
C11. (Which is pretty much bullshit, because both mandate threads and
some form of thread-local storage - so there's no excuse why
implementation couldn't implement this in a thread-safe way. Especially
with C11 this is ridiculous, because there is no way to use threads and
convert error numbers to strings at the same time!)
Since we heavily use threads now, we should avoid unsafe functions like
strerror().
strerror_r() is in POSIX, but GNU/glibc deliberately fucks it up and
gives the function different semantics than the POSIX one. It's a bit of
work to convince this piece of shit to expose the POSIX standard
function, and not the messed up GNU one.
strerror_l() is also in POSIX, but only since the 2008 standard, and
thus is not widespread.
The solution is using avlibc (libavutil, by its official name), which
handles the unportable details for us, mostly. We avoid some pain.
Always create the context in mpgl_init(), instead of doing it when
mpgl_config_window() is called the first time. This is a small step
towards cleaning up the GL backend interface, and adding other things
like perhaps GLES support, or a callback-driven backend for libmpv.
This sub-option was turned into a flag when the sub-option parser was
changed to the generic one (probably accidentally). Turn it into a
proper choice-option.
Also, adjust what the options do. Though none of this probably makes
much sense; the default should work, and if it doesn't, the GPU/driver
is probably beyond help.
Remove the extra vf_chain.output field - there's absolutely no need for
it, because there is always a last filter which will buffer the output.
For some reason, vf_chain.last was never set, which we now need to fix
too.
When initialization failed, vo_lavc may cause an irrecoverable state in
the ffmpeg-related structs. Therefore, we reject additional
initialization attempts at least until we know a better way to clean up
the mess.
ao_lavc currently cannot be initialized more than once, yet it's good to
do consistent changes there as well.
Also, clean up uninit-after-failure handling to be less spammy.
The previous fix breaks another obscure case: if the second vf_sub adds
margins, the image is accidentally not extended, which would return in
an assertion failure when returning the bogus image.
