*	lavf: replace AVStream.codec with AVStream.codecpar	Anton Khirnov	2016-02-23
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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_unref	Luca Barbato	2015-10-26
\| \| \| \| \| \| \|	`av_packet_unref` matches the AVFrame ref-counted API and can be used as a drop in replacement. Deprecate `av_free_packet`.

*	lavf: make av_set_pts_info private.	Anton Khirnov	2011-11-30
\| \| \| \|	It's supposed to be called only from (de)muxers.
*	pulse: compute frame_duration once and fix it	Luca Barbato	2011-11-14
\| \| \| \| \| \| \| \|	The frame duration was calculated without taking in account the bytes per sample. Thanks to Lorenzo Pistone <blaffablaffa@gmail.com> for pointing the issue and providing an initial fix.
*	pulse: introduce pulseaudio input	Luca Barbato	2011-10-26
	It currently use the simple api and is using the latency information provided only to offset the stream start. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
