7756	add mastering display color volume and content light level information to hevc_metadata bitstream filter	sneaker		"It's currently already possible to use the ""[https://ffmpeg.org/ffmpeg-bitstream-filters.html#hevc_005fmetadata hevc_metadata"" bitstream filter] (-bsf:v hevc_metadata) to add or change colour_primaries, transfer_characteristics and matrix_coefficients of a given HEVC bitstream losslessly. The only things missing to allow ffmpeg to properly set HDR metadata on existing HEVC streams would be to set SMPTE ST 2086 Mastering display color volume SEI and Content light level information SEI message (MaxCLL and MaxFALL).

This is useful because not all encoders currently allow setting those as well as in the case you forgot setting them during encode time."	enhancement	new	wish	avcodec	git-master		hevc				0	0
