* 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`.

* Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov2012-08-07

* lavf: rename AVInputFormat.value to raw_codec_id.Anton Khirnov2012-01-31
| | | | It's only used by raw demuxers for storing the codec id.
* lavf: remove AVFormatParameters from AVFormatContext.read_header signatureAnton Khirnov2012-01-27

* gsm demuxer: use generic seeking instead of a gsm-specific function.Justin Ruggles2012-01-11
| | | | | Since packets all contain only a single block, the generic seek function can be used while still maintaining block-accuracy.
* gsm demuxer: return packets with only 1 gsm block at a time.Justin Ruggles2012-01-11
| | | | | fixes stream copy of raw gsm to mov. tested with QuickTime.
* lavf: make av_set_pts_info private.Anton Khirnov2011-11-30
| | | | It's supposed to be called only from (de)muxers.
* gsm demuxer: do not allocate packet twice.Justin Ruggles2011-11-02
| | | | fixes memleak with raw gsm demuxing.
* Create separate functions for the raw GSM demuxer.Justin Ruggles2011-11-02
Put the new raw GSM demuxer in its own file. Fixes raw GSM demuxing.
