HP Truevision HD 内置网络摄像头在 ubuntu 18.04 中无法使用

我有一台 HP Notebook-15-ac603tu,从 Windows 转换到 Ubuntu 后,相机停止工作了。

我已经运行以下命令并得到输出:

奶酪显示黑屏的屏幕截图

我几乎尝试了所有方法,但我不知道如何继续(基本上是个新手用户)。请帮我操作我的网络摄像头。

错误消息cheese与此报告中的类似:

sudo解决办法是在调用时使用cheese

链接中的其他用户建议在cheese不起作用时使用其他可以起作用的软件包。

也就是说,使用以下命令确保网络摄像头已连接:

$ sudo apt install hwinfo

$ hwinfo --usb

您可以获得大量相同的信息,lsbusb -v但它不会以相同的方式简明扼要地提供这些信息。

我在 Acer 笔记本电脑上安装的 Ubuntu 18.04 发行版中遇到了类似的网络摄像头问题,并发布了类似的问题2 个月前。该笔记本使用了 Realtek Semiconductor Corp. 的网络摄像头。我发现它不是可识别的USB 视频类 Linux 设备。因此,这种不兼容性导致 cheese 应用程序出现如您所展示的空白屏幕。

我怀疑你的笔记本电脑网络摄像头设备

Bus 001 Device 042: ID 0bda:57d6 Realtek Semiconductor Corp.,  or
Bus 001 Device 003: ID 0bda:b006 Realtek Semiconductor Corp. 

不管怎样,它们似乎也不是 USB 视频类 Linux 设备。如果是,则uvcvideo无法初始化它,这就是为什么 cheese 应用程序显示为空白,如您的屏幕截图所示。

因此,在您的网络摄像头设备成为 USB 视频类 Linux 设备之前,它可能无法与 兼容uvcvideo

答案3

检查您的用户 ID 是否在“视频”组中。我有一台装有相同摄像头的 HP 笔记本电脑,据我所知,它使用标准的“uvcvideo”驱动程序模块。但您不能从不在视频组中的用户使用它。
