--- Comment #10 from Ludio ljerabek@cox.net --- I patched my code so I could get black and white video which was good enough for security cameras. Unfortunately I have not done any other tests since I identified the issue. If I remember correctly the color information was not being passed to the lower functions. If the surface information is properly being passed (unlike before) you should be able to extract the color approximations.
