Subject: [PATCH v3 14/22] media: uapi: Bump the STREAMS bit a little
Date: Wed, 25 Mar 2026 12:58:11 +0200 [thread overview]
Message-ID: <20260325105818.1176816-16-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20260325105818.1176816-1-sakari.ailus@linux.intel.com>
Bump the V4L2_SUBDEV_CAP_STREAMS by one bit up, order to avoid confusing
libcamera with streams that has moved forward from the original libcamera
implementation. The bit can presumably be taken into use but only after
the other free bits.
