WSL2中不工作在奶酪中的照相机

Question

我正在努力让我的笔记本电脑的网络摄像头在奶酪上工作，但我得到了这样的输出：

mohab@DESKTOP-VUD35O1:~$ cheese
** Message: 17:24:15.307: cheese-application.vala:214: Error during camera setup: No device found

奶酪不能探测到摄像机，也什么也不做。这只是一个空白的屏幕。也没有/dev/video。

我把摄像头和USBIP连接成这样：

PS C:\Users\mohab> usbipd wsl list

如何在Windows10Home的WSL2中使用我的相机？

Answer 1

要在WSL2中启用相机支持，您需要编译内核来包含它，因为默认的WSL2内核不包括支持它所需的模块，使用这个指南编译内核来包含这些必需的模块之后，您就可以在WSL2中通过附加它来使用摄像头了，在Windows端有PowerShell的USBIP。

注意:您需要在WSL2中获得USB支持，如果您还没有对它的支持，请使用此指南。

像这样

PS C:\Users\mohab> usbipd wsl list

BUSID  VID:PID    DEVICE    STATE                                                    

3-4    2232:1029  WebCam SC-13HDL11939N                                         Not attached

4-3    8086:0189  Generic Bluetooth Adapter                                     Not attached


PS C:\Users\mohab> USBIPD WSL  attach -b 3-4

PS C:\Users\mohab> usbipd wsl list

BUSID  VID:PID    DEVICE    STATE                                                    
                                   

3-4    2232:1029  WebCam SC-13HDL11939N                                         Attached - Ubuntu

4-3    8086:0189  Generic Bluetooth Adapter                                     Not attached

注意:当连接到WSL2时，您可能无法使用windows侧的摄像头，如果要再次在windows侧使用相机，则可以在Windows侧使用PowerShell将其与Windows侧的PowerShell分离。像这样的PS C:\Users\mohab> usbipd wsl detach -b 3-4

或者将您的相机从主机(WSL2 )流到来宾( cam2web Ubuntu)，但您必须每次都获得IP地址，但它不能与Cheese一起工作，内核编译将适用于每个程序，而这种方式只适用于支持http流(VLC、FFmpeg、Webbrowsers)的程序，而不适用于只支持像Cheese这样的物理相机的程序，这些程序需要/dev/video0或任何物理连接的摄像机，而不是IP摄像机。
