Subject: [PATCH v4 07/11] media: cedrus: Specify the required H264 start code
Date: Thu,  8 Aug 2019 07:34:28 -0300	[thread overview]
Message-ID: <20190808103432.12062-8-ezequiel@collabora.com> (raw)
In-Reply-To: <20190808103432.12062-1-ezequiel@collabora.com>

The cedrus VPU expects V4L2_PIX_FMT_H264_SLICE buffers to contain
H264 slices with no start code. Expose this to userspace with
the newly added menu control.
