Comment (by llogan): It is not possible to simply physically concat MP4 on a file level such as by using the concat protocol and expect it to work. From the [https://ffmpeg.org/faq.html#How-can-I-join-video-files_003f FAQ] regarding the concat protocol: > A few multimedia containers (MPEG-1, MPEG-2 PS, DV) allow one to concatenate video by merely concatenating the files containing them. As Carl said, use the concat demuxer or concat filter instead for your MP4 inputs. -- Ticket URL: <https://trac.ffmpeg.org/ticket/6902#comment:3> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://ffmpeg.org/mailman/listinfo/ffmpeg-trac
