* Add Cinepak encoderTomas Härdin2017-07-05
| | | | | | With permission of Tomas Härdin applied by Rl aetey.se Signed-off-by: Diego Biurrun <diego@biurrun.de>
* dxva: add support for new dxva2 and d3d11 hwaccel APIswm42017-06-08
| | | | | | | | | | This also adds support to avconv (which is trivial due to the new hwaccel API being generic enough). The new decoder setup code in dxva2.c is significantly based on work by Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* lavu: add new D3D11 pixfmt and hwcontextwm42017-06-08
| | | | | | | | | | | | | | | | | | | | To be used with the new d3d11 hwaccel decode API. With the new hwaccel API, we don't want surfaces to depend on the decoder (other than the required dimension and format). The old D3D11VA pixfmt uses ID3D11VideoDecoderOutputView pointers, which include the decoder configuration, and thus is incompatible with the new hwaccel API. This patch introduces AV_PIX_FMT_D3D11, which uses ID3D11Texture2D and an index. It's simpler and compatible with the new hwaccel API. The introduced hwcontext supports only the new pixfmt. Frame upload code untested. Significantly based on work by Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites. Signed-off-by: Diego Biurrun <diego@biurrun.de>

* aac: Split function to parse ADTS header data into public and private partDiego Biurrun2017-05-02
| | | | | | This makes the currently semi-public avpriv_aac_parse_header() function private to libavcodec and adds a proper public API function to return the parts of the ADTS header required in libavformat.
* hwcontext: Improve allocation in derived contextsMark Thompson2017-04-30
| | | | | | | Use the flags argument of av_hwframe_ctx_create_derived() to pass the mapping flags which will be used on allocation. Also, set the format and hardware context on the allocated frame automatically - the user should not be required to do this themselves.
* avconv: Support setting the hardware device to use when filteringMark Thompson2017-04-30
| | | | | | This only supports one device globally, but more can be used by passing them with input streams in hw_frames_ctx or by deriving new devices inside a filter graph with hwmap.

* vp9: Add bsf to fix reordering in raw streamsMark Thompson2017-04-02
| | | | | | Takes a raw input stream containing frames with correct timestamps but possibly out of order and inserts additional show-existing-frame packets to correct the ordering.
* vp9: Add bsf to merge superframesRonald S. Bultje2017-04-02
| | | | From ffmpeg commit 2e6636aa87303d37b112e79f093ca39500f92364.

* lavc: Add hwaccel_flags field to AVCodecContextwm42017-03-20
| | | | | | | | This "reuses" the flags introduced for the av_vdpau_bind_context() API function, and makes them available to all hwaccels. This does not affect the current vdpau API, as av_vdpau_bind_context() should obviously override the AVCodecContext.hwaccel_flags flags for the sake of compatibility.
* hwcontext: Make it easier to work with device typesMark Thompson2017-03-20
| | | | | | Adds functions to convert to/from strings and a function to iterate over all supported device types. Also adds a new invalid type AV_HWDEVICE_TYPE_NONE, which acts as a sentinel value.
* hwcontext: Add device derivationMark Thompson2017-03-20
| | | | | Creates a new device context from another of a different type which refers to the same underlying hardware.
* Add Cineform HD DecoderKieran Kunhya2017-03-09
| | | | | | | | | | Decodes YUV 4:2:2 10-bit and RGB 12-bit files. Older files with more subbands, skips, Bayer, alpha not supported.

* build: Prefer NASM assembler over YASMDiego Biurrun2017-03-07
| | | | | NASM is more actively maintained and permits generating dependency information as a sideeffect of assembling, thus cutting build times in half.

* lavc: Add device context field to AVCodecContextMark Thompson2017-02-13
| | | | For use by codec implementations which can allocate frames internally.
* AVFrame: add an opaque_ref fieldwm42017-02-11
| | | | | | | | | | | | | | | This is an extended version of the AVFrame.opaque field, which can be used to attach arbitrary user information to an AVFrame. The usefulness of the opaque field is rather limited, because it can store only up to 32 bits of information (or 64 bit on 64 bit systems). It's not possible to set this field to a memory allocation, because there is no way to deallocate it correctly. The opaque_ref field circumvents this by letting the user set an AVBuffer, which makes the user data refcounted. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* frame: allow align=0 (meaning automatic) for av_frame_get_buffer()Anton Khirnov2017-02-11
| | | | | This will avoid every caller from hardcoding some specific alignment, which may break in the future with new instruction sets.
* cpu: add a function for querying maximum required data alignmentAnton Khirnov2017-02-11
|
* avio: add a destructor for AVIOContextAnton Khirnov2017-02-11
| | | | | Before this commit, AVIOContext is to be freed with a plain av_free(), which prevents us from adding any deeper structure to it.
* lavc: deprecate refcounted_frames fieldwm42017-02-01
| | | | | | | | | No deprecation guards, because the old decode API (for which this field is needed) doesn't have any either. This field should be removed together with the old decode calls. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* avconv: allow -b to be used with streamcopyAnton Khirnov2017-02-01
| | | | In this mode it tells the muxer about the bitrate of the input stream.

* lavc: add an option for exporting cropping information to the callerAnton Khirnov2017-01-12
| | | | | Also, add generic code for handling cropping, so the decoders can export just the cropping size and not bother with the rest.
* frame: add a cropping rectangle to AVFrameAnton Khirnov2017-01-12
| | | | | Extend the width/height doxy to clarify that it should store coded values.
* crypto: consistently use size_t as type for length parametersDiego Biurrun2017-01-09
| | | | size_t is the correct type to use for sizes.
* fate: Add --ignore-tests configure option for omitting specific FATE testsJanne Grunau2016-12-28
| | | | | | | | | This can be useful to filter out noise in known-broken scenarios like miscompilation by legacy compilers and similar. Originally based on a patch by Diego Biurrun. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* lavc: add a bitstream filter for splitting VP9 superframesAnton Khirnov2016-12-14
| | | | Partially based on code by Ronald S. Bultje <rsbultje@gmail.com>.
* lavc: add a null bitstream filterAnton Khirnov2016-12-14
| | | | | | It is useful for testing/debugging and will also be used as the default filter in the following commit adding pre-decode filtering to avoid having a separate non-filtered codepath.

* lavu: Add AVSphericalMapping type and frame side dataVittorio Giovara2016-12-07
| | | | | | | | While no decoder currently exports spherical information, this type represents a frame property that has to be passed through from container to frames. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* Remove Plan 9 supportDiego Biurrun2016-12-03
| | | | | | Supporting the system was a nice joke for the 9 release, but it has run its course. Nowadays Plan 9 receives no testing and has no practical usefulness.
