* 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.

* ape: do not set AVCodecContext.frame_size.Justin Ruggles2012-03-05

* ape: skip packets with invalid sizeJustin Ruggles2012-02-06
|
* ape: calculate final packet size instead of guessingJustin Ruggles2012-02-06
| | | | | | | Calculates based on total file size and wavetaillength from the header. Falls back to multiplying finalframeblocks by 8 instead of 4 so that it will at least be overestimating for 24-bit. Currently it can underestimate the final packet size, leading to decoding errors.
* ape: stop reading after the last frame has been readJustin Ruggles2012-02-06
| | | | This avoids buffer overread when the last packet size estimate is too small.
