Certainly; you would use something like:

ffprobe -i input.file -show_streams -select_streams v:0

This would print information about the first video stream to STDOUT in
key=value pairs. On Linux I would parse this with sed (to find the
apropriate line & strip the key), I'm sure there's an equivalent for
Windows. Check out the ffprobe documentation:
