Again, this is a batch/cmd issue and you might find more success in
resolving your issue by asking on stackoverflow or somewhere that can
provide better .bat help. I know how to solve your issue with bash and
python, but I don't know enough about Windows batch scripts. It sounds like
you need to store the output of ffprobe as a variable in your batch
scripts, but it looks like that's not the easiest thing to do in windows
batch scripts, though it's a very simple process in other scripting
languages.
