| * lavf: fix usage of AVIOContext.seekableAnton Khirnov2016-09-30
| | | | | | | | | | | | | | | | It is supposed to be a flag. The only currently defined value is AVIO_SEEKABLE_NORMAL, but other ones may be added in the future. However all the current lavf code treats this field as a bool (mainly for historical reasons). Change all those cases to properly check for AVIO_SEEKABLE_NORMAL.

* | avformat/wavdec: Eliminate goto for clang -O0 DCEMark Harris2016-12-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clang is not able to eliminate the reference to ff_spdif_probe() when there is a goto target in the same block and optimization is disabled. This fixes the following build failure on OS X: ./configure --disable-everything --disable-doc \ --enable-decoder=pcm_s16le --enable-demuxer=wav \ --enable-protocol=file --disable-optimizations --cc=clang make ...

| * 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.
