C++11 tidying. 2022-01-07T22:23:08Z Carl Hetherington cth@carlh.net 2022-01-07T22:22:48Z urn:sha1:2ac6688e4e75ff26db9208e760966bd071dcc48f Ignore errors from avcodec_send_packet. 2021-10-13T13:50:13Z Carl Hetherington cth@carlh.net 2021-10-13T13:50:13Z urn:sha1:a70e10c59ae1314a3d8e1d44e060dbfe1c7cb7e8 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. Replace aligned bool with enum Alignment. 2021-09-27T11:41:46Z Carl Hetherington cth@carlh.net 2021-09-15T21:36:21Z urn:sha1:3799e91d126d243d41c44dcb0ca1bfa66b53a57e Various alignment adjustments. 2021-09-27T11:41:46Z Carl Hetherington cth@carlh.net 2021-09-14T23:00:33Z urn:sha1:9bfa07293928c371d59db2091ba2b7e715ce5994 Fix missing subtitles embedded in files decoded by FFmpeg (#2060). 2021-09-12T23:22:00Z Carl Hetherington cth@carlh.net 2021-09-12T20:43:52Z urn:sha1:60450bd93af0b331d7b98c88aa199366305f0721 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. Add missing avsubtitle_free(). 2021-09-12T23:22:00Z Carl Hetherington cth@carlh.net 2021-09-12T20:43:38Z urn:sha1:df811a0dd2772417496991b72fde0ef3304241d9 Fix errors when seeking FFmpeg for some formats. 2021-06-04T20:31:07Z Carl Hetherington cth@carlh.net 2021-06-03T20:55:44Z urn:sha1:9f4cb3b340376d93be39dc97c2e0c631e9cf73c4 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.
