Could you describe what are the advantages of the new filter, compared to existing solutions like vf_libplacebo inverse tone mapping? Additionally if there is a big gap in libplacebo's inverse tone mapping quality would you be interested in improving the libplacebo implementation in addition to this filter? I think there would be a gain in having real time gpu implementation too. - Kacper _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
