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.

`av_packet_unref` matches the AVFrame ref-counted API and can be used as a drop in replacement. Deprecate `av_free_packet`.

The only case where RTP_FLAG_KEY actually is needed is in RDT, where such a flag needs to be passed via the rtpdec parse function's flags parameter. Signed-off-by: Martin Storsjö <martin@martin.st>

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>

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>

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>

This will allow us to avoid copying the packets in many cases. This breaks ABI.
