| * lavc: introduce a new decoding/encoding API with decoupled input/outputwm42016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, the decoding API was restricted to outputting 0 or 1 frames per input packet. It also enforces a somewhat rigid dataflow in general. This new API seeks to relax these restrictions by decoupling input and output. Instead of doing a single call on each decode step, which may consume the packet and may produce output, the new API requires the user to send input first, and then ask for output. For now, there are no codecs supporting this API. The API can work with codecs using the old API, and most code added here is to make them interoperate. The reverse is not possible, although for audio it might. Signed-off-by: Anton Khirnov <anton@khirnov.net>

| * 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.

| * lavf: allow custom IO for all filesAnton Khirnov2016-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some (de)muxers open additional files beyond the main IO context. Currently, they call avio_open() directly, which prevents the caller from using custom IO for such streams. This commit adds callbacks to AVFormatContext that default to avio_open2()/avio_close(), but can be overridden by the caller. All muxers and demuxers using AVIO are switched to using those callbacks instead of calling avio_open()/avio_close() directly. (de)muxers that use the URLProtocol layer directly instead of AVIO remain unconverted for now. This should be fixed in later commits.

* | lavf: add automatic bitstream filtering; bump versionRodger Combs2015-12-28
| | | | | | | | | | | | | | | | | | This solves the problem discussed in https://ffmpeg.org/pipermail/ffmpeg-devel/2015-September/179238.html by allowing AVCodec::write_header to be delayed until after packets have been run through required bitstream filters in order to generate global extradata. It also provides a mechanism by which a muxer can add a bitstream filter to a stream automatically, rather than prompting the user to do so.
