我也遇到了这个错误。

emulator -webcam-list -avd Nexus_S_API_23
emulator: WARNING: Increasing RAM size to 1GB
emulator: ERROR: camera_device_start_capturing: Device 'AndroidEmulatorVC0' is unable to save frame to the clipboard: 0

注意:当我尝试从 Android 浏览器下载图像时遇到错误。

您尝试过其中一种吗？您的相机服务似乎无法正常工作/相机可能被用于其他应用程序。

Failed to connect to camera service

Use the web camera in the android emulator

顺便说一下，我使用 MacOSX。我只是说，它适用于我的机器。我发送了安装的工具和日志。也许它有帮助。

VD Configuration

Nexus 5, API 23 (Both Cameras are selected)

当我启动模拟器时，它会在日志中发出警告，但最终它起作用了。
