Be good to see the actual command line string you used. ( maybe link
to the files as well ).
I've stated what happened, when I tried with the command line I quoted, namely,
ffmpeg -i video_file1.mp4 -i audio_file.m4a -filter_complex '[0:0] /
[0:1] [0:0] concat=n=2:v=1:a=1' -strict -2 combined.mp4
I'll maybe try some different input files, see if behaviour is the
same. If so, and its not I, whom is it being
counter-intuitive, and then maybe time to file a bug report?
