Using cropdetect in ffmpeg

[tsmgeek]

What would be fairly cool is a way to use cropdetect with ffmpeg. It would be nice that somehow this could be implemented as part of a workflow.

http://www.renevolution.com/understanding-ffmpeg-part-iii-cropping/ Below is an example of the console output when you add -vf cropdetect. You run ffmpeg once outputting to a dummy file, only run a few seconds, then you have to run ffmpeg again with one of the supplied crop params ie crop=720:352:0:66 and bingo you get blackbars taken out.

Looks interesting, however I don't have the time at the moment to do that, but if you do a pull request I would happily merge it in.
