Detailed Description

Descriptor that unambiguously describes how the bits of a pixel are stored in the up to 4 data planes of an image.

It also stores the subsampling factors and number of components.

Note
This is separate of the colorspace (RGB, YCbCr, YPbPr, JPEG-style YUV and all the YUV variants) AVPixFmtDescriptor just stores how values are stored not what these values represent.
