| * hevcdec: move the MD5 context out of HEVCSEIPictureHash back into HEVCContextAnton Khirnov2017-05-20
| | | | | | | | | | | | | | HEVCSEIPictureHash should store only the information extracted from the bitstream and exported to the higher layer (the decoder or the parser). The MD5 context is allocated, used and freed by this higher layer, so it makes more sense for it to also be stored there.
| * hevcdec: remove HEVCContext usage from hevc_seiJames Almer2017-05-09
| | | | | | | | | | | | | | | | | | | | Based on the H264 SEI implementation. This will be mainly useful once support for SEI messages that can be used by the hevc parser are implemented, like Picture Timing.

| * hevcdec: Use LOCAL_ALIGNED_* for declaring local variables with alignmentMartin Storsjö2017-03-29
| | | | | | | | | | | | | | | | | | | | | | | | Not all compilers can do alignment larger than the normal stack alignment for variables on the stack. In these cases, the LOCAL_ALIGNED_* macros produce the workaround alignment wrapper consisting of a padded array and a pointer variable. This fixes the hevc fate tests on RVCT/ARMCC after adding IDCT assembly that actually assumes/relies on this alignment. Signed-off-by: Martin Storsjö <martin@martin.st>

* | hevcdec: properly export some side data with frame threadingwm42017-06-30
| | | | | | | | | | | | | | | | | | | | | | I noticed this with mastering display data. If frame threading is enabled, this side data is exported only for some frames. It turns out it's not properly propagated to the worker threads. I didn't touch A53 captions, because that involves memory allocation and freeing the data as side data is exported. Micro bump so that API users can detect the bug fix.
* | hevc: Add support for alternative transfer characterics SEIVittorio Giovara2017-06-28
| | | | | | | | | | | | | | | | | | | | The use of this SEI is for backward compatibility in HLG HDR systems: older devices that cannot interpret the "arib-std-b67" transfer will get the compatible transfer (usually bt709 or bt2020) from the VUI, while newer devices that can interpret HDR will read the SEI and use its value instead.

* | dxva: add support for new dxva2 and d3d11 hwaccel APIswm42017-06-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Merges Libav commit f9e7a2f95a7194a8736cc1416a03a1a0155a3e9f. Also adds untested VP9 support. The check for DXVA2 COBJs is removed. Just update your MinGW to something newer than a 5 year old release. Signed-off-by: Diego Biurrun <diego@biurrun.de>

* | hevc: fix race condition in max_ra/seq_decode.Ronald S. Bultje2017-05-25
| | | | | | | | | | | | | | | | | | | | These variables are shared between frame threads, but they are updated post-setup_finished() if a EOB/EOS slice type occurs. Moving the EOB/EOS slices to the next frame thread instance (by parsing them leading into the next picture instead of trailing behind the last picture) effectively prevents this race condition. This fixes tsan failures on hevc-conformance-NoOutPrior_A_Qualcomm_1.

* | hevc: only write to max_ra and pocTid0 in the first slice.Ronald S. Bultje2017-04-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Values from subsequent values are guaranteed to be identical (since poc and nal_unit_type are checked to be the same between slices), so this doesn't affect output in any way, but does resolve the remaining reported race conditions (by tsan) in fate-hevc. In practice, this fixes tsan warnings like this: WARNING: ThreadSanitizer: data race (pid=25334) Read of size 4 at 0x7d9c0001adcc by main thread (mutexes: write M1386): #0 hevc_update_thread_context src/libavcodec/hevcdec.c:3310 (ffmpeg+0x000000b41c7c) [..] Previous write of size 4 at 0x7d9c0001adcc by thread T1 (mutexes: write M1383): #0 hls_slice_header src/libavcodec/hevcdec.c:596 (ffmpeg+0x000000b43a22)
