This filter does HDR(HDR10/HLG) to SDR conversion with tone-mapping. An example command to use this filter with vaapi codecs: FFMPEG -init_hw_device vaapi=va:/dev/dri/renderD128 -init_hw_device \ opencl=ocl@va -hwaccel vaapi -hwaccel_device va -hwaccel_output_format \ vaapi -i INPUT -filter_hw_device ocl -filter_complex \ '[0:v]hwmap,tonemap_opencl=t=bt2020:tonemap=linear:format=p010[x1]; \ [x1]hwmap=derive_device=vaapi:reverse=1' -c:v hevc_vaapi -profile 2 OUTPUT Signed-off-by: Ruiling Song <ruiling.song@intel.com>
