I'm at the experimentation stage with ffmpeg as well, so.. ;o)
In the interests of same, I tried the following command,
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
During the conversion I received,
[output stream 0:0 @ 0x1b27dc0] 100 buffers queued in output stream
0:0, something may be wrong.
in the console output, just after completion of video section, though
the conversion itself appeared to complete successfully.
While the two files were indeed concatenated in the combined file, the
video section repeated itself while the appended audio file was being
played! Is this what happened when you tried it?
The version of mmpeg used was,
