问题描述
我正在尝试让 CSI 摄像机在我的 Coral Board 上工作。
当我尝试 dmesg | grep csi 时，我得到：
[ 3.400266] mxc-mipi-csi2_yav 30a70000.mipi_csi1: mipi_csi2_probe
[ 3.406489] CSI: Registered sensor subdevice: mxc-mipi-csi2.0
[ 3.412328] mxc-mipi-csi2_yav 30a70000.mipi_csi: Remote device at /mipi_csi1@30a70000/port/endpoint1 XXX found
[ 3.422363] mxc-mipi-csi2_yav 30a70000.mipi_csi1: lanes: 2,name: mxc-mipi-csi2.0
/dev/video0 可用，但也是唯一可用的视频设备。
v4l2-ctl --all 显示以下设备：

但是当我尝试使用 ffplay /dev/video0 获取输出时，我只会收到以下错误。

这是否意味着相机正常工作？
