Subject: [PATCH v6 06/15] media: v4l: Add V4L2-PIX-FMT-Y12P format
Date: Fri, 1 Mar 2024 23:32:21 +0200 [thread overview]
Message-ID: <20240301213231.10340-7-laurent.pinchart@ideasonboard.com> (raw)
In-Reply-To: <20240301213231.10340-1-laurent.pinchart@ideasonboard.com>
From: Jean-Michel Hautbois <jeanmichel.hautbois@ideasonboard.com>
This is a packed grey-scale image format with a depth of 12 bits per
pixel. Two consecutive pixels are packed into 3 bytes. The first 2 bytes
contain the 8 high order bits of the pixels, and the 3rd byte contains
the 4 least significants bits of each pixel, in the same order.
Add the entry in userspace API, and document it.
