Writing YUV data into a CGContext

Question

How can I write a YUV frame data into a CGContext?

Answer 1

Convert it to RGB, then create a CGImage with it, then draw that into the context.

Alternatively, create a CGColorSpace that maps YUV into RGB, then create a CGImage with it, then draw that into the context. (I have no idea whether this is possible, but you may want to look into it.)
