Subject: [PATCH] media: amphion: G/S_PARM only for encoder's output queue
Date: Mon, 9 May 2022 15:52:25 +0800 [thread overview]
Message-ID: <20220509075225.8031-1-ming.qian@nxp.com> (raw)
G/S_PARM doesn't make sense for the capture queue of a stateful encoder,
unless V4L2_FMT_FLAG_ENC_CAP_FRAME_INTERVAL is set to reserve hardware
resources.
Otherwise it will fail the v4l2-compliance
