Hello All,
I am working on a fb driver for linux in an embedded PPC setup. 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 ?
Best - Federico
