We've encountered something similar when transcoding FFV1 over the network. So we used framemd5 not to verify FFV1's losslessness, but to validate that the transcoding goes error-free :) FFmpeg's framemd5 became *the* feature for professional video preservation. So, thanks again for all your great work here! Regards, Pb _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
