RGB -> planar YCrCb 4:2:0

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi; I need to convert a frame from RGB to planar YCrCb 4:2:0. The frame is in
a large unsigned char array (width * height * 3), or in a unsigned char
matriz ((height) x (width * 3)); it's the same.

I need a fast library that does that for me, or a pointer to where I can find
a fast algorithm.

Thanks.
