For ffmpeg, look at

	-padtop	number_of_pixels
	-padbottom number_of_pixels
	-padleft number_of_pixels
	-padright number_of_pixels
	-padcolor color  ( 000000 = black , 00ff00 = green, ... )

Setting the padcolor to something like green is an easy way to see what you
are getting.  Also useful for figuring out how much overscan a display has.

If they are already letterboxed/pillerboxed and you want to remove it,

	-cropleft
	-cropright
	...

I'd guess you need to process each piece individually into a common
format, then splice them together.
