Changes in the command line output that broke such a parsing algorithm have
been very infrequent in the past and should lead to easy-to-catch errors in
your application. so as long as you test your application after an ffmpeg
update, you should be fine. I know of a few applications using that
approach which have been running for years *and* updated ffmpeg regularly
without this becoming a problem.
