Gyan Doshi	4f8c691040	avformat/mpegenc - log error msgs for unsupported LPCM streams The MPEG-PS muxer only accepts PCM streams having up to 8 channels and the following sampling rates: 32/44.1/48/96 kHz. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	7 years ago
Gyan Doshi	f0809bc0fa	avformat/mpegenc - accept PCM_DVD streams PCM_S16BE stream packets in MPEG-PS have a 3-byte header and are recognized as PCM_DVD by the demuxer which prevents their correct remuxing in MPEG-1/2 PS. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	7 years ago
Gyan Doshi	b99e77b9f7	avformat/mpegenc - fix typo in VBV warning Default VBV buffer size is 230KB, not 130KB. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	7 years ago

Anton Khirnov	9200514ad8	lavf: replace AVStream.codec with AVStream.codecpar 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.	9 years ago
