I'm not 100% sure. I am currently working on an arexx script that uses ffmpeg -i (run from Art Effect to build a preview of 20 thumbnails from a selected video, and then prints data about the video at the top). It's working ok, but I can't figure out how to accurately parse fps, and I'm getting the resolution from a frame grab, which could be problematic if I decide to go with scaling.

When I google some of the features of -i, I'm seeing a number of threads where people are asking questions, and somewhere in the answers someone says "just use ffprobe".

I'm thinking of switching to mplayer. It appears to produce data on a video in an easy-to-parse format, although some of the results I don't quite understand (codecs are returned as codes, so I guess I would need to map those to whatever).
