How about a newer version instead of an older one (though I acknowledge that you could find a regression by going backwards)? git master HEAD is recommended on this list. > - Every media are from the same codec h264. That does not suffice. From the docs: https://www.ffmpeg.org/ffmpeg-formats.html#concat-1 All files must have the same streams (same codecs, same time base, etc.). The duration of each file is used to adjust the timestamps of the next file: if the duration is incorrect (because it was computed using the bit-rate or because the file is truncated, for example), it can cause artifacts. The duration directive can be used to override the duration stored in each file.
