[PATCH v3 0/9] Add HSV format
From: Ricardo Ribalda Delgado
Date: Sat Jul 16 2016 - 06:42:39 EST
HSV formats are extremely useful for image segmentation. This set of
patches makes v4l2 aware of this kind of formats.
Vivid changes have been divided to ease the reviewing process.
We are working on patches for Gstreamer and OpenCV that will make use
of these formats.
We still need to decide if and how we will support HUE range 0-255
