Subject: [RFC PATCH v2 1/7] media: v4l: Add V4L2-PIX-FMT-Y12P format
Date: Fri, 21 Jan 2022 09:18:04 +0100 [thread overview]
Message-ID: <20220121081810.155500-2-jeanmichel.hautbois@ideasonboard.com> (raw)
In-Reply-To: <20220121081810.155500-1-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.
