I'm not sure what the most appropriate method is, but I would probably pick the stream with the longest duration. Stream 0:0 is probably just a thumbnail/single frame, whereas stream 0:2 is probably an actual video. Check AVStream.duration (if it's set). _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
