--sub-ass=no / --ass=no still work, but --ass-style-override=strip is
preferred now. With this change, --ass-style-override can control all
the types of style overriding.
In particular, this moves the depth test to common code.
Should be functionally equivalent, except that for DXVA2, the
IDirectXVideoDecoderService_GetDecoderRenderTargets API is called
more often potentially.
Because it's annoying and feels unnatural.
If the B point is set while paused, don't seek. If not paused, it should
properly loop immediately.
In theory there's a chance that it will show at least 1 frame after the
loop point when setting the B point. But let's not care about that.
This gives us 16 bit fixed-point integer texture formats, including
ability to sample from them with linear filtering, and using them as FBO
attachments.
The integer texture format path is still there for the sake of ANGLE,
which does not support GL_EXT_texture_norm16 yet.
The change to pass_dither() is needed, because the code path using
GL_R16 for the dither texture relies on glTexImage2D being able to
convert from GL_FLOAT to GL_R16. GLES does not allow this. This could be
trivially fixed by doing the conversion ourselves, but I'm too lazy to
do this now.
This fixes backstepping getting "stuck" when e.g. holding down a key
bound to the backstep command. The reason is that even if the backstep
itself is finished, the next backstep might not take the new video PTS
as reference if the hr-seek itself isn't finished yet.
The intention of not waiting for the hr-seek to finish was faster
backstepping by possibly skipping audio decoding. But it probably
doesn't matter enough to make the rest of the code more complex.
Basically this gets rid of the need for the accessors in d3d11va.h, and
the code can be cleaned up a little bit.
Note that libavcodec only defines a ID3D11VideoDecoderOutputView pointer
in the last plane pointers, but it tolerates/passes through the other
plane pointers we set.
This uses ID3D11VideoProcessor to convert the video to a RGBA surface,
which is then bound to ANGLE. Currently ANGLE does not provide any way
to bind nv12 surfaces directly, so this will have to do.
ID3D11VideoContext1 would give us slightly more control about the
colorspace conversion, though it's still not good, and not available
in MinGW headers yet.
The video processor is created lazily, because we need to have the coded
frame size, of which AVFrame and mp_image have no concept of. Doing the
creation lazily is less of a pain than somehow hacking the coded frame
size into mp_image.
I'm not really sure how ID3D11VideoProcessorInputView is supposed to
work. We recreate it on every frame, which is simple and hopefully
doesn't affect performance.
As a positive side-effect, this also errors out gracefully for the
extremely unlikely but possible case certain builtin filters are not
available. (This could happen only with crippled libavfilter builds that
can't be used by anything using its public API.)
Setting this here is a race condition. It's called from a CoreAudio
callbacks, and there are no locks. It's a string, so this can be
potentially severe.
It's hard to fix and only CoreAudio supported it, so remove it.
This causes the "audio-out-detected-device" property to return nothing
on all platforms.
Sucks, but better than freezing forever given the (to me) unpredictable
RPI behavior. This will be good enough to drop out of vsync timing mode,
or to abort playback.
Recreate all dispmanx objects after mode changes signalled by the TV
callback. This is needed since dispmanx objects are marked as invalid
and cease working.
One important point is that the vsync callbacks will stop coming when
this happens, so restoring the callback is important.
Note that the MMAL renderer itself does not get trashed by the firmware
on such events, but we completely reconfigure it anyway when it happens.
For Mediacodec in particular we don't care about the format. It can just
decode to whatever it wants. The only case we would care about is it not
returning an opaque format if we don't have proper interop, but
libavcodec always returns non-opaque formats by default.
Use the recently added lavc_suffix mechanism to select the wrapper
decoder.
With all hwdec callbacks being optional, and RPI/Mediacodec having only
dummy callbacks, all the callbacks can be removed as well.
The result is that the vd_lavc_hwdec struct for both of them is tiny.
It's better to move them to vd_lavc.c directly, because they are so
trivial and small.
This is intended for cases when --hwdec needs to override the decoder
implementation in use, like for example on the RPI.
It does two things:
1. Allow the hwdec to indicate a decoder suffix. libavcodec by
convention adds a suffix to all wrapper decoders, and here we start
relying on it. While not necessarily the best idea, it's the only
thing we got. libavcodec's hwaccel list is useless, because it only
has the codec ID, not the associated decoder's name.
2. Make --hwdec=auto work properly. It shouldn't fail anymore, and hwdec
probing should reliably work, even if a different decoder is selected
with --vd. The semantics of --hwdec should dictate that it overrides
the default decoder.
A minor simplification. Most callers don't need this, and there's no
good reason why the caller should provide an "initializer" like this.
(This function calls mp_image_new_dummy_ref(), which has no reason
for an initializer either.)
Another crappy fix for timestamp reset issues. This time, we try to fix
files which have very weird but legitimate frame durations, such as
cdgraphics. It can have many short frames, but once in a while there are
potentially very long frames.
Fixes#3027.
The active texture and some pixelstore parameters are now always reset
to defaults when entering and leaving the renderer. Could be important
for libmpv.
Commit 382bafcb changed the behavior for ab-loop-a. This commit changes
ab-loop-b so that the behavior is symmetric.
Adjust the OSD rendering accordingly to the two changes.
Also fix mentions of the "ab_loop" command to the now preferred
"ab-loop".
The check whether video is ready yet was done only in STATUS_FILLING.
But it also switched to STATUS_READY, which means the next time
fill_audio_out_buffers() was called, audio would actually be started
before video.
In most situations, this bug didn't show up, because it was only
triggered if the demuxer didn't provide video packets quickly enough,
but did for audio packets.
Also log when audio is started.
(I hate fill_audio_out_buffers(), why did I write it?)
Strictly schedule an update in regular intervals as long as either
stream cache or demuxer are prefetching. Don't update just always
because the stream cache is enabled ("idle != -1") or cache-related
properties are observed (mp_client_event_is_registered()).
Also, the "idle" variable was awkard; get rid of it with equivalent
code.
