标题: usb3.0UVC摄像头不能获取视频和图片
我用板子系统是Linux debian10.toybrick 4.4.194 #16 SMP Thu Apr 8 18:10:29 CST 2021 aarch64 GNU/Linux 摄像头型号：cyusb3065 MIPI图像，用这个USB3.0芯片转接，接到USB3.0接口内核和文件系统均为最新版
我用/usr/share/rockchip-isp里面的实例代码，不能够获取到usb3.0的视频流，用cheese显示/dev/video0 no device found。用  499  sudo v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=YUV422 --stream-mmap=3 --stream-to=/tmp/1920_480.yuv --stream-count=1 命令会卡住。摄像头的信息v4l2-ctl --all --list-formats-ext

我该怎么做来支持我的摄像头？？

作者: troy 时间: 2021-12-2 18:26
手上有源码的话，可以menuconfig看一下USB UVC相关的配置宏是否打开了。

是不是找错设备号了，你拔插以下摄像头，看看增加的是哪个？ls /dev/video*

troy，你好，我的usb2.0摄像头是好使的，是不是可以确认系统开启了uvc驱动呢，还有我用guvcview工具是可以看到usb3.0摄像头，但是视频很卡顿，macfee_feng插拔看到的是/dev/video0和/dev/video1。这是我插上usb3.0摄像头的dmesg，[103368.695544] usb 4-1.4: new SuperSpeed USB device number 10 using xhci-hcd

这是我lsusb 情况 4e45:5501就是usb3.0摄像头
root@debian10:/zty# lsusb
Bus 004 Device 011: ID 4e45:550 ...

USB2.0可以用，那UVC配置应该是正常的。至于你说的视频卡顿问题，应该是分辨率太大，USB的带宽顶不住。虽然板子上有3.0的口，但是都是从Hub上分出来的，3.0的Hub上，如果有挂2.0的设备，那么只会被当做2.0使用。

troy，能帮我分析一下，为什么v4l2命令和/usr/share/rockchip-isp里面的实例代码，不能够获取到usb3.0的视频流的原因么？以及cheese获取不到设备，我该如何调试？

USB Camera估计要自己看一下，这个是内核标准的驱动，跟一下ioctl命令，是不是有哪些没实现。
