VMware Horizon View Client for Linux Help : Using the Real-Time Audio-Video Feature for Webcams and Microphones : When You Can Use Your Webcam

When You Can Use Your Webcam
If your Horizon View administrator has configured the Real-Time Audio-Video feature, and if you use the PCoIP display protocol, a webcam that is built-in or connected to your local computer can be used on your desktop. You can use the webcam in conferencing applications such as Skype, Webex, or Google Hangouts.
During the setup of an application such as Skype, Webex, or Google Hangouts on your View desktop, you can choose VMware Virtual Microphone and VMware Virtual Webcam as input devices and VMware Virtual Audio as output device from menus in the application. With many applications, however, this feature will just work, and selecting an input device will not be necessary.
If the webcam is currently being used by your local computer it cannot be used by the View desktop simultaneously. Also, if the webcam is being used by the View desktop it cannot be used by your local computer at the same time.
If you have more than one webcam connected to your local computer, your administrator can configure a preferred webcam that will be used on your View desktop. Consult with your Horizon View administrator if you are not sure which webcam is selected.
