* 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.

* ogg: update event_flags with STREAM_/METADATA_UPDATED whenever metadata changes.Andrew Stone2014-08-13
| | | | | | | | | | | | | | Originally, AVFormatContext and a metadata dict were provided to ff_vorbis_comment(), but this presented issues if an AVStream was being updated or the metadata on AVFormatContext wasn't actually being updated. To remedy this, ff_vorbis_stream_comment() explicitly updates a stream's metadata and sets any necessary flags. ff_vorbis_comment() does not modify any flags, and any calls to it that update AVFormatContext's metadata (just a single call) must also update AVFormatContext.event_flags after detecting any metadata changes to the provided dictionary, as signaled by a positive return value.

* lavf: Reset the entry count and allocation size variables on av_reallocp ↵Martin Storsjö2013-09-26
| | | | | | | | | | | | | | failures When av_reallocp fails, the associated variables that keep track of the number of elements in the array (and in some cases, the separate number of allocated elements) need to be reset. Not all of these might technically be needed, but it's better to reset them if in doubt, to make sure variables don't end up conflicting. Signed-off-by: Martin Storsjö <martin@martin.st>
