The alternative_transfer_characteristics SEI message shall be inserted on the HEVC DVB_RAP, and preferred_transfer_characteristics shall be set equal to "18", indicating Recommendation ITU-R BT. 2100 [45] HLG system."

* lavc/qsvenc: add Tiles encode support for HEVCLinjie Fu2019-12-12
| | | | | | | | | | | | | | | | | | | | | | Add -tile_rows and -tile_cols option to specify the number of tile rows and columns for ICL+ (gen 11) platform. A tile must wholly contain all the slices within it. Slices cannot cross tile boundaries. So the slice number would be implicitly resized to the max(nSlice, nTile). Example: ffmpeg -v verbose -hwaccel qsv -init_hw_device qsv=hw -filter_hw_device hw -f rawvideo -s:v 1920x1080 -i ./input.nv12 -vf format=nv12,hwupload=extra_hw_frames=64 -c:v hevc_qsv -tile_rows 2 -tile_cols 2 -slices 4 -y output.h265 Also dump the actual quantity of encoded tiled rows and columns in run time. Fix the enhancement #8400. Signed-off-by: Linjie Fu <linjie.fu@intel.com>

* avformat/matroskadec: avcodec/tta: Set extradata_size to 22Andreas Rheinhardt2019-12-04
| | | | | | | | | | | | | | | Up until c4e0e314, the seek table has been included in the tta extradata, so that the size of said extradata was 22 (the size of a TTA1 header) + 4 * number of frames. The decoder rejected anything below a size of 30 and so the Matroska demuxer exported 30 byte long extradata, of which only 18 were set (it ignores a CRC-32 and simply leaves it at 0). But this is unnecessary since said commit, so reduce the size to 22. Furthermore, replace 30 by 22 in a comment about the extradata size in libavcodec/tta.c.
