如何检查网络摄像头是否损坏？

我刚买了一台 Acer Aspire 3830TG，它配备了集成的 1.3M 高清网络摄像头。在购买之前，我尝试使用可启动的 Lubuntu USB 棒，除了网络摄像头之外，一切都运行良好，我认为我必须对其进行调整。

问题是，相机在 ubuntu 中似乎应该可以正常工作。驱动程序已检测到，我试过了

dmesg | grep uvcvideo

输出为

[   12.226174] uvcvideo: Found UVC 1.00 device 1.3M HD WebCam (058f:b002)
[   12.245553] usbcore: registered new interface driver uvcvideo

我也尝试过使用不同的软件（当相机输出为 MJPG 时，guvcview 为黑色，当为 YU12 或 YV12 时，会变成奇怪的颜色，cheese 始终为黑色，camorama 始终带有奇怪的颜色）。

我应该检查它是否在默认操作系统（Windows）下正常运行，但现在为时已晚。我甚至从 USB 笔启动了官方 Ubuntu Quantal 发行版，结果是一样的。

有什么方法可以检查摄像头是否正常或损坏？如果摄像头坏了，至少我可以去商店，向他们证明摄像头确实坏了，然后免费获得一个外置摄像头，或者类似的东西。

我运行了sudo lsinput，关于我的视频的输出信息如下：

/dev/input/event6
   bustype : BUS_USB
   vendor  : 0x58f
   product : 0xb002
   version : 2
   name    : "1.3M HD WebCam"
   phys    : "usb-0000:00:1a.0-1.3/button"
   bits ev : EV_SYN EV_KEY

/dev/input/event7
   bustype : BUS_HOST
   vendor  : 0x0
   product : 0x6
   version : 0
   name    : "Video Bus"
   phys    : "LNXVIDEO/video/input0"
   bits ev : EV_SYN EV_KEY

有了这些信息，我不确定是否运行该luvcview命令。当我运行 时luvcview -d /dev/video0 -L，输出如下：

如果我单独运行 luvcview，图像会很有趣（主要是蓝色和红色，我自己处于负面状态）。

答案1

安装“input-utils”包并执行“sudo lsinput”。您将看到很多设备，但请查找视频设备。

如果可行，请安装软件包“luvcview”并执行“luvcview -d /dev/video0 -L”，看看它是否连接并输出设备的功能。如果您的 lsinput 指示它是其他设备（/dev/video1 是常见的），请使用它。
