get FPS value from mediainfo into a bat script

[ricardouk]

Hi everyone!

Im doing a semi automatic conversion script and ive stopeed at the bit where i need to get the FPS value from a file on to the script.

Is there any easy way of doing this, i need the fps because it seems mp4 box needs that value to mux 264+aac into mp4 container, im using mencoder...ive read that mencoder can also "read" the fps from a file, mediainfo can also read that value.

Any suggestions?

use -identify switch, but not with mencoder, with mplayer.
mplayer will print some output to stdout.
