* lavc: add codec parameters APIAnton Khirnov2016-02-23
| | | | | | This API is intended to allow passing around codec parameters without using full AVCodecContext (which also contains codec options and encoder/decoder state).
* lavf: add a protocol whitelist/blacklist for file opened internallyAnton Khirnov2016-02-22
| | | | | | | | Should make the default behaviour safer for careless callers that open random untrusted files. Bug-Id: CVE-2016-1897 Bug-Id: CVE-2016-1898

* 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.
* APIchanges: Add missing av_pix_fmt_get_chroma_sub_sample entryLuca Barbato2016-01-11

* lavc: add profiles to AVCodecDescriptorAnton Khirnov2015-12-12
| | | | | The profiles are a property of the codec, so it makes sense to export them through AVCodecDescriptors, not just the codec implementations.
* lavc: export Dirac parsing API used by the ogg demuxer as publicAnton Khirnov2015-12-06
| | | | Also, stop using AVCodecContext for storing the stream parameters.
* lavc: add a packet side data type for VBV-like parametersAnton Khirnov2015-12-06
|
* lavc: add stream-global packet side dataAnton Khirnov2015-12-06
| | | | This is similar to what is done for AVStream.
* avpacket: add a function for wrapping existing data as side dataAnton Khirnov2015-12-06

* lavc: Deprecate avctx.rtp_callback fieldVittorio Giovara2015-11-20
| | | | | | | | | | | | | | | | | | | | | This function returns the encoded data of a frame, one slice at a time directly when that slice is encoded, instead of waiting for the full frame to be done. However this field has a debatable usefulness, since it looks like it is just a convoluted way to get data at lowest possible latency, or a somewhat hacky way to store h263 in RFC-2190 rtp encapsulation. Moreover when multi-threading is enabled (which is by default) the order of returned slices is not deterministic at all, making the use of this function not reliable at all (or at the very least, more complicated than it should be). So, for the reasons stated above, and being used by only a single encoder family (mpegvideo), this field is deemed unnecessary, overcomplicated, and not really belonging to libavcodec. Libavformat features a complete implementation of RFC-2190, for any other case. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* avcodec: Define side data type for fallback trackJohn Stebbins2015-11-18
| | | | | | | | | This side data type is meant to be added to AVStream side data. A fallback track indicates an alternate track to use when the current track can not be decoded for some reason. e.g. no decoder available for codec. Signed-off-by: Anton Khirnov <anton@khirnov.net>

| | | | | Pave the way for having the size of the AVPacket struct not part of the ABI.
* avpacket: Deprecate av_dup_packetLuca Barbato2015-10-26
| | | | | As documented, `av_dup_packet` is broken by design, `av_packet_ref` matches the AVFrame ref-counted API and can be safely used instead.
* 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`.

* lavc: Add data and linesize to AVSubtitleRectVittorio Giovara2015-10-21
| | | | | | | | | | | | Use the new fields directly instead of the ones from AVPicture. This removes a layer of indirection which serves no pratical purpose whatsoever, and will help in removing AVPicture structure completely later. Every subtitle encoder/decoder seamlessly points to the new arrays, so it is possible to deprecate AVSubtitleRect.pict. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* lavc: Make AVPacket.duration int64, and deprecate convergence_durationwm42015-09-29
| | | | | | | | | Note that convergence_duration had another meaning, one which was in practice never used. The only real use for it was a 64 bit replacement for the duration field. It's better just to make duration 64 bits, and to get rid of it. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* examples/qsvdec: free the lavc decoder before closing MFX/VAAPIAnton Khirnov2015-09-28

* examples/qsvdec: do not free the surfaces in the frame_free() callbackAnton Khirnov2015-09-28
| | | | | Even though libmfx might not need them anymore, avcodec might still access the surfaces. So free them separately at the end.
