Interesting: ffmpeg doesn't close one output correctly, if the other
one fails? (I didn't double check, but that is an undesired limitation,
if you ask me. I'm not using the word "bug" yet. ;-))

If you can manage to use the "tee" muxer instead of two outputs, it has
the option "onfail" which should control this behavior:
onfail
Specify behaviour on output failure. This can be set to either
abort (which is default) or ignore. abort will cause whole
process to fail in case of failure on this slave output. ignore
will ignore failure on this output, so other outputs will
continue without being affected.
Note that your file will then just continue encoding, you would need to
terminate it separately with a signal or a keypress. I assume the file
would be correctly closed then (untested, as mentioned).
Hope this helps,
Moritz
