[FFmpeg-devel] Copyplane filter

[Gavin Kinsey]

I've written a filter that copies RGBA image planes.  I'm using it to create 
an alpha mask from a b&w image.  I'd like to make it work for YUV data too, 
but before I do that I'd like to get some feedback on the current code.

This is my first attempt at doing anything with avfilter and a lot of it is 
just blindly copying from other filters, so there is probably a lot of stuff 
in there that doesn't need to be and likely important stuff missing too.

Appreciate any feedback.
