So the question is:
Can I apply the RGB texture using certain texture coordinates, and then apply an Alpha texture, using different pix_coordinate settings? Since I would want the alpha channel to clamp to the edges of the geo and not slide off as the RGB texture does...
I think its impossible since the RGB and A are considered the same "texture".
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)
have you tried [colorSquare] ?
Also I realized I think the video source will be YUV anyhow...
Say, does v4l provide YUV or RGB?
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)
