- Core Video
A pixel buffer attributes dictionary is a Core Foundation dictionary containing zero or more of these keys and appropriate values. Core Video functions such as
CVPixel accept pixel buffer attributes dictionaries to describe how to allocate pixel buffers for compatibility with client requirements. Where multiple CoreVideo clients seek to exchange pixel buffers,
CVPixel can be used to find a common pixel buffer attributes dictionary that is compatible with all the clients' pixel buffer attributes dictionaries.
