HP Truvision HD 上的网络摄像头无法正常工作

我正在使用HP 15-ac650tu. 任何应用程序/Google Meet 都说无法检测到任何网络摄像头cheese。这是调用或 时的错误sudo cheese。两个命令都会在终端上抛出相同的错误，并且窗口全黑。

现在我在平台上看到了一些类似的问题，但没有真正的解决方案。我在 Ubuntu 18.04.5 上，这里有更多信息。

如果有人能阐明这个问题我将不胜感激。

编辑： 按照这，这可能是一个错误。尝试使用卡莫拉马或 gstreamer，检查是否能正常工作。如果能，那么你可能遇到了这个 bug。

有关的：

建议尝试解决问题：

  1. sudo调用时使用cheese(參考）。

建议如果提出的解决方案不起作用，为了增加获得帮助和解决问题的机会，请执行以下操作：

  1. 发布您所说的“当尝试开始时”的确切含义。

  2. 发布列出的命令的输出HP Truevision HD 内置网络摄像头在 ubuntu 18.04 中无法使用

  3. 每当您发布命令的输出时，请发布用于生成该输出的确切命令。

  4. 关注问题的可读性。如果可以提高可读性，请稍微编辑和重新组织。
