And it produces out.mp3 (876805 bytes) with exit code 0
Now a slightly modified command using filter_complex prints different
error which look almost like the process failed

}}}
And produced out.mp3 is only 876712 bytes and exit code 183.
I wonder what is happening here? Why these two similar commands produce
different output, one that appears as success and the other one as a
failure?
I actually need to run `filter_complex` b/c there are many filters I need
to apply etc. So is there any magic flag/filter/custom decoder I can apply
to fix the problem?
