"copy" is a placeholder for not running codec at all. In your program that implements this logic, you should "short-circuit" the demuxer and the muxer. Note that in some cases, you cannot avoid running the video codec, because it is the way to extract global headers, etc. BR, Alex Cohn _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
