Subject: [PATCHv2 13/19] media: common: saa7146: fall back to V4L2_PIX_FMT_BGR24
Date: Thu, 23 Mar 2023 16:53:37 +0100	[thread overview]
Message-ID: <20230323155343.2399473-14-hverkuil-cisco@xs4all.nl> (raw)
In-Reply-To: <20230323155343.2399473-1-hverkuil-cisco@xs4all.nl>

If the requested pixelformat is not supported, then fall
back to V4L2_PIX_FMT_BGR24 for improved V4L2 compliance.
