* 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.

* aud: remove unneeded field, audio_stream_index from contextJustin Ruggles2012-01-24
| | | | | There is only one stream, so it will always be index 0. This also allows for removal of the private context.
* aud: fix time stamp calculation for ADPCM IMA WSJustin Ruggles2012-01-24
| | | | also allows for removing some unused context fields
* aud: simplify header parsingJustin Ruggles2012-01-24
| | | | also allows for removing some unused context fields
* aud: set pts_wrap_bits to 64.Justin Ruggles2012-01-24
| | | | Time stamps are not read from the bitstream, so no wrapping is needed.

* aud: support Westwood SND1 audio in AUD files.Justin Ruggles2012-01-24
| | | | | | | Fixes decoding of the handful of "death scream" samples from "Command and Conquer" that use SND1. e.g. http://samples.libav.org/game-formats/westwood-aud/nuyell1.aud http://samples.libav.org/game-formats/westwood-aud/nuyell7.aud
* westwood: split the AUD and VQA demuxers into separate files.Justin Ruggles2012-01-23
They have no code in common.
