I tried in the past and it is indeed possible, however it doesn't really work: going that route you'll end up adding all the color properties, including chroma location. As much as I despise the J formats, it's a hacky solution at best leading to a very confusing API, making the negotiation and conversion unnecessary complex. If we were to break this feature, I'd suggest going the full route of adding a PixelFormaton and work on a sws alternative (one is allowed to dream no?). -- Vittorio _______________________________________________ ffmpeg-devel mailing list email@example.com http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
