Most likely. Note that if it returns 1, it's still possible the output
file is ok (though in that case I'd say it's usually a hint that your
command isn't 100% right).

You can also set the loglevel (you'd probably want "-loglevel error"
in your case, maybe "-loglevel warning") and read output from stderr
and optionally display it to the user as "these things may have caused
your output to not be quite right" (though a lot of the time ffmpeg
will generate ok output despite reporting errors and warnings, as it
tries its best to recover from these things).

Then you have to assume you and I define "ok output" as the same thing :)
