this would require some multitexture thing (as you have stated, you 
cannot give different texture-coordinates for the RGB and the A channels 
of one texture)

that depends on the capture-device
most devices will give YUV (which is by-default converted to RGBA, 
unless you set the colorspace to YUV)
