I'm expert to this very subject. I'm stating that filter is good at reducing/removing abrupt changes in color/brightness for typical videos. On another hand, you are pointing to irrelevant corner cases. Besides user can increase number of frames used in calculation of changes. What I will not ever tolerate is your belittling other peoples work. _______________________________________________ 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".
