That sounds exactly like the mosaic plugin. (see
http://wiki.videolan.org/Mosaic )

Mosaic input items can use specific filters including one called
"alphamask". It only supports png images as input for the time being but
it wouldn't be too hard to change that to using another movie stream.

Could you please be a bit more precise with what you want to acheive so
I can be a bit more specific? (Documentation on all that mosaic stuff is
kind of sparse ... it's mainly in the svn commit messages)
