* 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.

* gxf: Add a local copy of the relevant parts of the frame rate tableMartin Storsjö2012-10-18
| | | | | | | | | | | | | This avoids having to share this table across the library boundaries. This shared table used to be problematic, if always declaring all exported data symbols with the dllimport attribute (even while building that same library), since it needs to be a link-time constant when it is used in AVCodec declarations (in mpeg12enc.c).

* lavf: make av_set_pts_info private.Anton Khirnov2011-11-30
| | | | It's supposed to be called only from (de)muxers.
* lavc: use avpriv_ prefix for ff_frame_rate_tab.Anton Khirnov2011-10-20
| | | | It's used in lavf.
* lavf: replace av_new_stream->avformat_new_stream part II.Anton Khirnov2011-10-19
| | | | | | | | Manual replacements are done in this commit. In many cases, the id is some constant made up number (e.g. 0 for video and 1 for audio), which is then not used in the demuxer for anything. Those ids are removed.
* lavf: use designated initialisers for all (de)muxers.Anton Khirnov2011-07-17
| | | | It's more readable and less prone to breakage.
* gxf: Fix 25 fps DV material in GXF being misdetected as 50 fpsTomas Härdin2011-07-09
| | | | | | | | Set DV packet durations using fields_per_frame. This requires turning gxf_stream_info into the demuxer's context for access to the value in gxf_packet(). Since MPEG-2 seems to work fine this done only for DV. Signed-off-by: Anton Khirnov <anton@khirnov.net>
