2022-01-11Fix failure to decode multiple video frames from one packet (#2159).Carl Hetherington
2022-01-11Cleanup: move some stuff into process_video_frame().Carl Hetherington
2022-01-11Use a separate AVFrame for each stream when decoding.Carl Hetherington
This seems to be what ffplay does and it feels like it makes sense as frames may be built from multiple packets AFAICS.

2021-10-13Ignore errors from avcodec_send_packet.Carl Hetherington
After seeking it appears that we often get irrelevant errors from this method. ffplay.c seems to ignore them, and this commit means that we do too (just logging them). I think these errors during a non-seeking "encoding" run could be cause for concern; perhaps we should take more note of them in that case.

2021-09-13Fix missing subtitles embedded in files decoded by FFmpeg (#2060).Carl Hetherington
Since the FFmpeg 4.4 update it seems that AVSubtitle::pts is no longer set (it's AV_NOPTS_VALUE, i think). Instead we apparently need to get the PTS from the packet, which in turn requires the stream's timebase.

2021-06-04Fix errors when seeking FFmpeg for some formats.Carl Hetherington
The comments discuss this in a bit more depth, but basically we see errors from avcodec_send_packet after seek. ffplay etc. seem basically to ignore all errors from avcodec_send_packet, and I can't find a "proper" fix, so here's a half-way house hack: ignore some errors after seek. Nasty.
2021-06-03Ignore errors from avcodec_receive_frame when flushing video (#2035).Carl Hetherington
The test fails if we don't do this; it doesn't really seem 100% convincing but we are already doing this for audio.

2021-03-02Tidy up and do flushing more correctly.v2.15.133Carl Hetherington
This seems necessary with the multi-threaded decoding; it looks like we were doing it quite wrong before but getting away with it.

2020-12-03Obey audio timestamps if they don't deviate by more than some threshold.Carl Hetherington
Previously we would ignore audio timestamps because they are not contiguous in a sample-accurate way. However with bugs like #1833 we do need to obey large discontinuities in audio timestamps, otherwise we get large sync errors. Here we change timestamp handling to ignore small discontinuities in timestamps but not larger ones.

instead, assume it should be at timestamp 0.

2019-05-05Stop video filters emitting frames from the old position justCarl Hetherington
after a seek. If this happens, we get sequences like 1. emit some video at time 60s 2. seek to 40s 3. video frame emitted from filter at 60.1s; this sets _last_video_time in player so that frames emitted between 40s and 60s are discarded; hence the audio buffers overflow. Should fix #1551.
