大家好,我对 v4l2-ctl 设置有疑问
眼镜: 处理器:IMX8MM, 内核版本:5.10.72 (hardknott yocto) 相机传感器:r MIPI-CSI OS02G10 总线: V4L2_MBUS_CSI2_DPHY 格式:RAW10 / BG10 ( SBGGR10) /1920x1080 问题: OS02G10 的驱动程序已实现类似于 ov5640 的 V4L2 控制基础结构。它使用子设备概念。 V4L2 无法处理已实现的控件,例如: root@user:~# v4l2-ctl --verbose -L VIDIOC_QUERYCAP: ok root@user:~# v4l2-ctl --set-ctrl brightness=192 unknown control 'brightness' 这是一个众所周知的问题,但希望有人能帮助我更快地找到解决方案。 如何解决? root@user:~# v4l2-ctl --list-devices i.MX6S_CSI (platform:32e20000.csi_bridge): /dev/video0 vsi_v4l2dec (platform:vsi_v4l2dec): /dev/video2 vsi_v4l2enc (platform:vsi_v4l2enc): /dev/video1 此处的所有其他详细信息: root@user:~# v4l2-compliance v4l2-compliance SHA: not available [ 334.897958] unknown pixelformat:'▒▒▒▒' [ 334.902049] mx6s-csi 32e20000.csi_bridge: Fourcc format (0xffffffff) invalid.
