Comment (by Michael Koch):
The amix filter has a "duration" option. It works if you set this option
to "shortest".
But this doesn't explain why the -shortest option doesn't work.
{{{
ffmpeg -i input.mp4 -i song.m4a -lavfi
[0:a][1:a]amix=duration=shortest[s0];[0:v]null[s1] -map [s0] -map [s1] -y
output.mp4
}}}
