... and this is even true if you do not use command substitution, but
a regular file:
file /dir/works
file /dir/$'\n'fails
file '/dir/fails
too'
I have found no way to make ffmpeg accept \n in a '-i' file.
If you cannot make it work in a regular file, it is unlikely to work
in a command substitution.
