* | avfilter: deprecate avfilter_link_get_channels()James Almer2018-01-051-0/+4

* | lavr: deprecate the entire libraryRostislav Pehlivanov2018-01-041-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | Deprecate the entire library. Merged years ago to provide compatibility with Libav, it remained unmaintained by the FFmpeg project and duplicated functionality provided by libswresample. In order to improve consistency and reduce attack surface, as well as to ease burden on maintainers, it has been deprecated. Users of this library are asked to migrate to libswresample, which, as well as providing more functionality, is faster and has higher accuracy.

* | lavc: replace and deprecate the lock managerwm42017-12-261-0/+5
| | | | | | | | | | | | | | Use static mutexes instead of requiring a lock manager. The behavior should be roughly the same before and after this change for API users which did not set the lock manager at all (except that a minor memory leak disappears).

* | avcodec: add metadata to identify wrappers and hardware decoderswm42017-12-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Explicitly identify decoder/encoder wrappers with a common name. This saves API users from guessing by the name suffix. For example, they don't have to guess that "h264_qsv" is the h264 QSV implementation, and instead they can just check the AVCodec .codec and .wrapper_name fields. Explicitly mark AVCodec entries that are hardware decoders or most likely hardware decoders with new AV_CODEC_CAPs. The purpose is allowing API users listing hardware decoders in a more generic way. The proposed AVCodecHWConfig does not provide this information fully, because it's concerned with decoder configuration, not information about the fact whether the hardware is used or not. AV_CODEC_CAP_HYBRID exists specifically for QSV, which can have software implementations in case the hardware is not capable. Based on a patch by Philip Langdale <philipl@overt.org>. Merges Libav commit 47687a2f8aca3f65b6fdd117b1cb66a7409a7fd1.

* | lavu,lavfi,ffmpeg: Remove experimental OpenCL APIMark Thompson2017-11-221-0/+3
| | | | | | | | | | | | | | | | | | | | | | This was added in early 2013 and abandoned several months later; as far as I can tell, there are no external users. Future OpenCL use will be via hwcontext, which requires neither special OpenCL-only API nor global state in libavutil. All internal users are also deleted - this is just the unsharp filter (replaced by unsharp_opencl, which is more flexible) and the deshake filter (no replacement).

| * lavc: external hardware frame pool initializationwm42017-10-191-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | This adds a new API, which allows the API user to query the required AVHWFramesContext parameters. This also reduces code duplication across the hwaccels by introducing ff_decode_get_hw_frames_ctx(), which uses the new API function. It takes care of initializing the hw_frames_ctx if needed, and does additional error handling and API usage checking. Support for VDA and Cuvid missing.

| * lavf: make avio_read_partial() publicwm42017-08-301-0/+3

| * imgutils: add function to clear an image to blackwm42017-07-261-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Black isn't always just memset(ptr, 0, size). Limited YUV in particular requires relatively non-obvious values, and filling a frame with repeating 0 bytes is disallowed in some contexts. With component sizes larger than 8 or packed YUV, this can become relatively complicated. So having a generic function for this seems helpful. In order to handle the complex cases in a generic way without destroying performance, this code attempts to compute a black pixel, and then uses that value to clear the image data quickly by using a function like memset. Common cases like yuv410p10 or rgba can't be handled with a simple memset, so there is some code to fill memory with 2/4/8 byte patterns. For the remaining cases, a generic slow fallback is used.

| * dxva: add support for new dxva2 and d3d11 hwaccel APIswm42017-06-081-0/+6
| | | | | | | | | | | | | | | | | | | | 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 hwcontextwm42017-06-081-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * hwcontext: Improve allocation in derived contextsMark Thompson2017-04-301-0/+4
| | | | | | | | | | | | | | 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.

| * lavc: Add hwaccel_flags field to AVCodecContextwm42017-03-201-0/+4
| | | | | | | | | | | | | | | | 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 Thompson2017-03-201-0/+4
| | | | | | | | | | | | 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.

| * AVFrame: add an opaque_ref fieldwm42017-02-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
