I will set the pixel format later and see if that gets it working. Re the framemd5, I should have been more clear. I wanted to use the framemd5s to prove that the video stream was altered when transcoding from 1:1 10bit to v210. I realise that it would just give a yes or no answer to this question. I honestly didn't have a clue how to compare them after that and see how much alteration occurs. Thanks yet again for your invaluable help. -K ------ This email has been scanned for spam and malware by The Email Laundry. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
