* 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.

* aacdec: Lower the number of frames required to detect ADTSMartin Storsjö2014-03-16
| | | | | | | | | | | For live audio streams, requiring 500 frames for a stream to be detected is a bit overkill. This allows live ADTS streams that don't start nicely at a frame boundary to start up more quickly, e.g. http://mp3.streampower.be/radio1.aac. Signed-off-by: Martin Storsjö <martin@martin.st>
* aacdec: Don't count probed ADTS frames if there are false positivesMartin Storsjö2014-03-16
| | | | | | | | | If a portion of the probe buffer seem to resemble ADTS frames, but some data at the end is a mismatch, disregard the whole probing attempt. If it actually is ADTS data, there shouldn't be any mismatches within the sequential frame data. Signed-off-by: Martin Storsjö <martin@martin.st>
