Still not happening, I'd like to see this done properly with hwdownload. While what you have works as a hack, we're not interested in hacks but something that works universally. As I said before, it can be easily sped up by a factor of 4 or 8 using SIMD, so its unjustifiable to have this in the codebase as a filter. _______________________________________________ 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".
