FFMPEG video thumbnails.

[camjac251]

I noticed from when uploading videos or music, thumbnails from either the id3 artwork or a screenshot of a video wouldn't be seen, instead you'd get the missing thumbnail image. I was thinking what if for videos, it'd generate a lossless png thumbnail from ffmpeg and a set frame. As for music you could retrieve the id3 info with getID3. Also for the thumbnails, would it be possible to have them cropped in, instead of scaled down to fit the 1:1 factor?

I like the idea, it's just a fairly complex thing to do that I'd rather not have to deal with. If anyone else manages to implement it cleanly, I'm always open to pull requests.
