大佬,我用的是toybrick-rk3399pro,想调用插在板子上的USB摄像头,插上USB会多出video10和video11,但是分别指定节点 cheese -d /dev/video10和11后,cheese依然显示的是there was an error playing video from the webcam.求大佬解答一下,怎么操作? |
- sudo v4l2-ctl -d /dev/video10 --set-fmt-video=width=640,height=480,pixelformat=YUYV --stream-mmap=3 --stream-to=/tmp/YUYV_640_480.out --stream-count=3 --stream-skip=10 --stream-poll
