BTW: If we declined to include the wrapper as part of FFmpeg mainline, this means SVT-HEVC need to maintain the FFmpeg wrapper patch set for this, I don't think this is a good idea if some guys want to try SVT-HEVC encoder from FFmpeg. > Relatedly, are there any results indicating how good this encoder actually > is, especially as compared to libx265 as the main existing software H.265 > encoder?
