That really only works if both files have the same specs. I just tried with your youtube links and it failed because of the apostophe in the downloaded filename file './A brief animation of David Hudson's theory of ormus.-Bhx3HEV_6FQ.mkv' so I removed that apostrophe and all worked fine. The order might have been off so you can just alter myfile.txt to get the right order. Or add something to the for loop that sorts everything in the way you like. -K _______________________________________________ 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".
