* 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.
* avpacket: Replace av_free_packet with av_packet_unrefLuca Barbato2015-10-26
| | | | | | | `av_packet_unref` matches the AVFrame ref-counted API and can be used as a drop in replacement. Deprecate `av_free_packet`.

* rtpdec: Rename the free method to closeMartin Storsjö2015-02-24
| | | | | | | | | Many of these functions were named foo_free_context, and since the functions no longer should free the context itself, only allocated elements within it, the previous naming was slightly misleading. Signed-off-by: Martin Storsjö <martin@martin.st>

* rtpdec: Don't free the payload context in the .free functionMartin Storsjö2015-02-24
| | | | | | | | | | | | | | This makes it more consistent with depacketizers that don't have any .free function at all, where the payload context is freed by the surrounding framework. Always free the context in the surrounding framework, having the individual depacketizers only free any data they've specifically allocated themselves. This is similar to how this works for demuxer/muxers/codecs - a component shouldn't free the priv_data that the framework has allocated for it. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: Remove unnecessary inline attributesMartin Storsjö2015-02-24
| | | | | | | These functions are far from performance critical, so there's no point in marking them as inline. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: Don't pass non-const pointers to fmtp attribute parsing functionsMartin Storsjö2015-02-24
| | | | | | | This makes it clear that the individual parsing functions can't touch the parsed out value. Signed-off-by: Martin Storsjö <martin@martin.st>

* rtsp: Don't expose the MS-RTSP RTX data stream to the callerMartin Storsjö2012-04-08
| | | | | | | | This avoids exposing a dummy AVStream which won't get any data and which will make avformat_find_stream_info wait for info about this stream. Signed-off-by: Martin Storsjö <martin@martin.st>
