2017-07-19avutil: merge slice threading implementation from avcodec and avfilterMuhammad Faiz
Rework it to improve performance. Now mutex is not shared by workers, instead each worker has its own mutex and condition variable. This reduces lock contention between workers. Also use atomic variable for counter. The interface also allows execute to run special function on main thread, requested by Ronald. Signed-off-by: Muhammad Faiz <mfcc64@gmail.com>

2017-06-27lavu: add new D3D11 pixfmt and hwcontextwm4
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. Merges Libav commit fff90422d181744cd75dbf011687ee7095f02875.

2017-05-15videotoolbox: add hwcontext supportwm4
This adds tons of code for no other benefit than making VideoToolbox support conform with the new hwaccel API (using hw_device_ctx and hw_frames_ctx). Since VideoToolbox decoding does not actually require the user to allocate frames, the new code does mostly nothing. One benefit is that ffmpeg_videotoolbox.c can be dropped once generic hwaccel support for ffmpeg.c is merged from Libav. Does not consider VDA or VideoToolbox encoding. Fun fact: the frame transfer functions are copied from vaapi, as the mapping makes copying generic boilerplate. Mapping itself is not exported by the VT code, because I don't know how to test.

2016-12-08avutil: fix data race in av_get_cpu_flags()Wan-Teh Chang
Make the one-time initialization in av_get_cpu_flags() thread-safe. The static variables |flags|, |cpuflags_mask|, and |checked| in libavutil/cpu.c are read and written using normal load and store operations. These are considered as data races. The fix is to use atomic load and store operations. Remove the |checked| variable because the invalid value of -1 for |flags| can be used to indicate the same condition. Rename |flags| to |cpu_flags| and move it to file scope. The fix can be verified by running the libavutil/tests/cpu_init.c test program under ThreadSanitizer: ./configure --toolchain=clang-tsan make libavutil/tests/cpu_init libavutil/tests/cpu_init There should be no warnings from ThreadSanitizer.

2016-01-19libavutil: add mastering display metadata sidedataNeil Birkbeck
Adding mastering display metadata struct to avutil. The mastering display metadata contains information about the mastering display color volume (SMPTE 2086:2014). This info comes from HEVC in the SEI_TYPE_MASTERING_DISPLAY_INFO and is soon to be included in MKV: https://mailarchive.ietf.org/arch/search/?email_list=cellar&gbt=1&index=sZyfPTM-QY69P-0omfOIiTN622o so it is similar to SEI FPA / stereo_mode in MKV and as such this patch follows how AVStereo3D is implemented. I'll add support to HEVC in a follow-up (and MKV when spec is approved). Signed-off-by: Neil Birkbeck <neil.birkbeck@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
