That's off topic, but I'll answer. I have tested it with my own test program using some sample screenshots, and it does what expected. Now I want to apply it to a live video. Of course there may be a little sanity check needed (I'm not sure yet how the filter deals with clippings), but in my use case there was no clipping at all (unless the filter is applied to a video it was not meant for). Of course, there is no completely opaque pixels in the png image, all they do have some transparency. And I suppose any equation will look strange without having a clue what the goal is, and how I even came to this solution. (Spoiler: it's a reverse equation of what some another filter does. If you like the quest - you may try to guess what it is). _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
