Okay. I'll explain. When I tried ffmpeg -i "concat:c:\1.mp4|2.mp4 .." and that failed on "duplicate MOOV Atom", I converted the MP4s, 1: to MKVs, and 2: to MPEGs, and 3: to VOBs, and repeated with each of them. In one of them I got "buffer underflow". I woke up this morning -- I'm in the US -- asking myself, "buffer underflow? How is that possible?" I don't remember which of the concats: MKVs or MPEGs or VOBs, did that. So, I don't have a log. A log should not be required to ask: "How is a buffer underflow possible when it's not a real time process?" _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
