Comment (by Michael Koch):
It seems the workaround with *.mov doesn't help in this case.
The issue can be reproduced with these simplified commands:
{{{
ffmpeg -f lavfi -i testsrc2 -f lavfi -i sine=2000 -t 5 -y input.mp4
ffmpeg -f lavfi -i sine=500 -t 10 -y song.m4a
ffmpeg -i input.mp4 -i song.m4a -lavfi [0:a][1:a]amix[s0];[0:v]null[s1]
-map [s0] -map [s1] -shortest -y output.mp4
}}}
