CALayer says that 'contents' is "typically a CGImageRef, but may be something else". I (optimistically) tried assigning the CVPixelBufferRef directly to the contents, but apparently that's not included in the mysterious 'something else' list.
Could you point out where it says that? Typically you would set the contents property either as a CGImageRef, or as the value of the contents of another layer (which would cause them to share contents).
The only way I've found of going from CVPixelBufferRef to CGImageRef is via CIImage, something like the following :
If you have a CVPixelBufferRef, you can use the various functions defined for a CVPixelBuffer to access the base address, row bytes, width, height and other attributes to create a CGImageRef directly from it via CGImageCreate(). You should be able to find more information by consulting the CoreVideo and Quartz references.
