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

Martin Storsjö	4fa57d524f	libavformat: Set the default for the max_delay option to -1 Make the muxers/demuxers that use the field handle the default -1 in the same way as 0. This allows distinguishing an intentionally set 0 from the default value where the user hasn't set it. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Reimar Döffinger	43d7c6118d	put_bits can only reliably write up to 31 bit bits, above it relies on undefined shift behaviour.

Ronald S. Bultje	f4ca612fbd	Set restrictions on packet_size, as per ISO-11172 / H-222 specifications (max packet size should fit in 13 bits as a kB value, so 1<<23, plus the header which is 10 bytes), and as per mpegenc.c internal assumptions (min packet size is 20 bytes).
