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`.

While I'm not sure why exactly sure why the old code could end up in the wrong position, using the generic index code is much simpler and is known to work correctly. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

It will be reused by other muxers and demuxers.

wv.c will be used for shared wavpack functions.

Currently the demuxer shaves the blocks and exports only the information that is useful to the decoder. Exporting the blocks just as they are stored is simpler to understand and will make remuxing wavpack easier.

This fixes the situation when there are not enough entries in the index (e.g. on initial seek there's only one index entry in the index) and index search returns just the last known entry. That causes seeking function just to seek there instead of trying harder to get at the requested position. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
