| | | | | | | | | | There is no change in the encoded bitstream, but this ensures that the written field length is consistent with the reference implementation. Unused bytes are zeroed out for backwards compatibility. Signed-off-by: Raphaël Zumer <rzumer@tebako.net>

* avformat/ivfenc: fix writing codec tagJames Almer2018-09-24
| | | | | | | | | The value in AVCodecParameters->codec_tag may not be correct for IVF, as it's the case when remuxing AV1 streams from mp4, so ignore it and write the correct value based on codec ID instead. Reviewed-by: Jan Ekström <jeebjp@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com>

| * lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.

| | | | | | | | | | | | | | | | Since 596e5d4783, this is not necessary anymore. It also allows to actually disable the flushing, improving write performance (but possibly giving worse latency in real-time streaming). Signed-off-by: Martin Storsjö <martin@martin.st>

| | | | | | | | | | | | | | | | | | | | | | VP80 fourcc are writed for all contexts (without ctx->codec_tag) how to reproduce the issue: 1) Get any vp9 video (for example http://base-n.de/webm/out9.webm) 2) ffmpeg -i out9.webm -vcodec copy out9.ivf 3) out9.ivf have VP80 fourcc at ivf header The proposed fix solves this issue Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
