and 16-aligned resolutions for the chrominance plane (with 2x2
subsampling).

- example, if a light blue pixel with 50% transparency was described
- by RGBA values (128, 192, 255, 128), the same pixel described with

This information supplements the ``colorspace`` and must be set by
the driver for capture streams and by the application for output
streams, see :ref:`colorspaces`.
