Add black bars instead of stretching

[alehel]

If I compare two videoes where 1 video has black bars and the other doesn't, the one without gets stretched to match aspect ratio of the one with. This happens a lot when I'm comparing my encodes to the original original file as I always crop out black bars when encoding. It would be usefull if video-compare could add an equal amount of black bars to the top/bottom of a video instead of stretching it so that the correct aspect ratio is maintained.

@alehel,

You can use the -land -r options with FFmpeg filters (crop/pad) to address that.

Wonderful. Thanks :)
