I have it working as far as linux is concerned, and I also understand the video card side of the problem. My trouble is: Linux sends me R G B and the hardware expects Y Cb Cr. As things work through a memory-mapped file, I am at a loss for an "intelligent" way to intercept and convert these values. Any suggestions ?
