Subject: [PATCHv4 1/5] media: v4l UAPI: add ROI selection targets
Date: Fri, 30 Apr 2021 20:26:07 +0900 [thread overview]
Message-ID: <20210430112611.475039-2-senozhatsky@chromium.org> (raw)
In-Reply-To: <20210430112611.475039-1-senozhatsky@chromium.org>
UVC 1.5 requires Region Of Interest control to implement
GET_CUR, GET_DEF, GET_MIN and GET_MAX requests. This patch
adds new V4L2 selection API targets that will implement
those ROI requests.
