Subject: [PATCH v10 0/3] vivid: Metadata support
Date: Tue, 8 Oct 2019 12:57:54 +0530 [thread overview]
Message-ID: <20191008072757.22752-1-bnvandana@gmail.com> (raw)
In-Reply-To: <96d53360-5520-f253-db8e-995bf5920746@xs4all.nl>
This patch adds metadata support in vivid driver.
Metadata capture supports UVCH format V4L2_META_FMT_UVC as it is widely used in webcams.
https://hverkuil.home.xs4all.nl/spec/uapi/v4l/pixfmt-meta-uvc.html
For Metadata output a new format V4L2_META_FMT_VIVID is added,
which is used to set brightness, contrast, sturation and hue.
Regards,
Vandana.
