This could in theory lead to missed updates if subtitles were switched
or external OSD overlays (via overlay-add) were updated. While the
change IDs of each of those were consistent, switching between two
separate OSD sources is not, and we have to explicitly trigger a change.
Regression since commit 9c9cf125. The new code is actually better,
because we do exactly what is needed, and don't just mess with the
update ID for libass-based OSD.
'cuda-gl' isn't right - you can turn this on without any GL and
get some non-zero benefit (with the cuda-copy hwaccel). So
'cuda-hwaccel' seems more consistent with everything else.
When playing audio-only, and changing the audio output device, playback
froze until the next time the playback core happened to wakeup (like
moving the mouse, or OSD redrawing). This is probably because of the
awful statemachine in fill_audio_out_buffers() - just make it recreate
the AO directly instead.
Remove the per-part force_redraw flags, and instead make the difference
between flagging dirty state and returning it to the player frontend
more explicit. The big issue is that 1. the OSD needs to know the dirty
state, and it should be cleared strictly when it is re-rendered
(force_redraw flag), and 2. the player core needs to be notified once,
and the notification must be reset (want_redraw flag).
The call in loadfile.c is replaced by making osd_set_sub() set the
change flag. Increasing the change flag on dirty state (the force_redraw
check in render_object()) should not be needed, because OSD part
renderers set it correctly (at least now).
Doing this just because someone pointed this out.
This also lets you just do "mpv --hwdec file.mkv", with the minor caveat
that the legacy syntax "--hwdec val" or "-hwdec val" (without "=") does
not work as expected anymore.
The previous commit merely copied the profile string to a file (plus
changing how RPI-specific defaults are initialized), now make some
changes on top of it. In particular, remove the --input-lirc option,
which was removed a long time ago, but forgotten from the libmpv
profile.
Move the embedded string with the builtin profiles to a separate
builtin.conf file. This makes it easier to read and edit, and you can
also check it for errors with --include=etc/builtin.conf. (Normally
errors are hidden intentionally, because there's no way to output error
messages this early, and because some options might not be present on
all platforms or with all configurations.)
Just wow. This function is implemented in ipc-win.c, and was surely be
meant to be called. But it wasn't called. This could in theory cause
crashes during exit if IPC clients were active.
Untested whether it really works.
This workaround prevented that libmpv users could accidentally crash
when the SIGPIPE signal was triggered by FFmpeg's OpenSSL/GnuTLS usage.
But it also modifies the global signal handler state, so remove it now
that this workaround is not required anymore.
This happened to break because the texture unit wasn't reset to 0, which
some code expects. The OSD code in particular set the OSD texture on the
wrong texture unit, with the result that OSD/OSC was not visible.
A minor cleanup that makes the code simpler, and guarantees that we
cleanup the GL state properly at any point.
We do this by reusing the uniform caching, and assigning each sampler
uniform its own texture unit by incrementing a counter. This has various
subtle consequences for the GL driver, which hopefully don't matter. For
example, it will bind fewer textures at a time, but also rebind them
more often.
For some reason we keep TEXUNIT_VIDEO_NUM, because it limits the number
of hook passes that can be bound at the same time.
OSD rendering is an exception: we do many passes with the same shader,
and rebinding the texture each pass. For now, this is handled in an
unclean way, and we make the shader cache reserve texture unit 0 for the
OSD texture. At a later point, we should allocate that one dynamically
too, and just pass the texture unit to the OSD rendering code. Right now
I feel like vo_rpi.c (may it rot in hell) is in the way.
The caller now has to call gl_sc_reset(), and _after_ rendering. This
way we can unset OpenGL state that was setup for rendering. This affects
the shader program, for example. The next commit uses this to
automatically manage texture units via the shader cache.
vo_rpi.c changes untested.
Stops Mesa from restricting us to OpenGL 3.0. It also tries to create
GLES 3 contexts for drivers which do not just return a higher context
when requesting GLES 2.
I don't know whether this code is a good or bad idea. A not-so-good
aspect is that we don't check for EGL 1.5 (or 1.4 extensions) for some
of the more advanced context attributes. But EGL implementations should
be able to tolerate it and return an error, and then we'd use the
fallback.
This used to be shared, but since vo_rpi is going to be removed,
untangle them. There was barely any actual code shared since the recent
changes anyway.
As a subtle change, we also stop opening libGLESv2.so explicitly in the
vo_opengl backend, and use RTLD_DEFAULT instead.
Minimal support just for testing.
Only the window surface creation (including size determination) is
really platform specific, so this could be some generic thing with
platform-specific support as some sort of sub-driver, but on the other
hand I don't see much of a need for such a thing.
While most of the fbdev usage is done by the EGL driver, using this
fbdev ioctl is apparently the only way to get the display resolution.
Add a function to egl_helpers.c for creating an EGL context and make
context_x11egl.c use it. This is meant to be generic, and should work
with other windowing APIs as well. The other EGL-using code in mpv can
be switched to it.
Edit the 0.21.0 section: remove the redundant vo_opengl items, move some
up. Move the additions (which are less important and which aren't
documented completely anyway) below the incompatible
changes/deprecations.
The wrong enum got copied here, so it was essentially using the transfer
characteristics as the primaries (instead of the primaries), which
accidentally worked fine most of the time (since the two usually
coincided), but broke on weird/mistagged files.
Fixes missing subtitle tracks if the first entry didn't have any.
Previously it just checked for the first entry in the playlist for
requested languages and if that entry happened to not have subtitles
they also wouldn't show up for the other entries.
It will skip languages if the first entry with subs has less or
different languages than the others.
Unrelated to http_dash_segments.
The consequence of this was that e.g. hardware decoding with VAAPI-EGL
could sometimes not work if the compiler didn't support C11. (Although I
found this one on RPI, which also uses this mechanism.)
If the shader fails to compile, and assertion could trigger in
gl_sc_gen_shader_and_reset() due to the code trying to recreate the
shader every time, and re-appending the uniforms every time. Just reset
the uniform array to fix this.
Some disturbed GL drivers might not return anything for glGetShaderiv()
if the GL state got "lost", so initialize variables just for additional
robustness.
Since vo_rpi is going to be deprecated, better port its features to the
vo_opengl backend.
The most tricky part is the fact that recreating dispmanx elements will
conflict with the GL context. Fortunately, RPI's EGL support is
reasonably compliant, and we can transplant the context to newly created
dispmanx elements, making this much easier. This means unlike vo_rpi,
the GL state will actually not be recreated.
This overlay support specifically skips the OpenGL rendering chain, and
uses GL rendering only for OSD/subtitles. This is for devices which
don't have performant GL support.
hwdec_rpi.c contains code ported from vo_rpi.c. vo_rpi.c is going to be
deprecated. I left in the code for uploading sw surfaces (as it might
be slightly more efficient for rendering sw decoded video), although
it's dead code for now.
When update_prop() successfully fetches a changed property value, it
sets prop->changed to true. mark_property_changed() only sets
prop->need_new_value if prop->changed is false, so this had the effect
of ignoring new property values until prop->changed was set back to
false in the next call to gen_property_change_event(). This meant that
when a property change event was generated for a property that was not
observed with MPV_FORMAT_NONE, it would contain the value associated
with the earliest property change, rather than the most recent, and the
property change event for the most recent change would never be
generated.
To fix this, mark_property_changed() should unconditionally set
prop->changed and prop->need_new_value, which will cause the property
value to be re-fetched and a property change event to be generated for
the most recent value.
The cuvid decoder already knows how to copy back to system memory
if NV12 frames are requested, and this will happen if the decoder
is used without the hwdec.
For convenience, let's add a wrapper hwdec so people don't have
to explicitly pick the cuvid decoder if they want this behaviour.
