Configure Real-Time Audio-Video
After you install Real-Time Audio-Video, the feature works on your Horizon View desktops without any
further configuration. The default values for the webcam frame rate and image resolution are recommended
for most standard devices and applications.
You can configure group policy settings to change these default values to adapt to particular applications,
webcams, or environments. See “Configuring Real-Time Audio-Video Group Policy Settings,” on page 37.
If users have multiple webcams and audio input devices built in or connected to their client computers, you
can configure preferred webcams and audio input devices that will be redirected to their desktops. See
“Selecting Preferred Webcams and Microphones,” on page 32.
NOTE You can select a preferred audio device, but no other audio configuration options are available.
When webcam images and audio input are redirected to a remote desktop, you cannot access the webcam
and audio devices on the local computer. Conversely, when these devices are in use on the local computer,
you cannot access them on the remote desktop.
Real-Time Audio-Video is not supported on local mode desktops.
For information about supported applications, see the VMware knowledge base article, Guidelines for Using
Real-Time Audio-Video with 3rd-Party Applications on Horizon View Desktops, at
http://kb.vmware.com/kb/2053754.
Ensuring That Real-Time Audio-Video Is Used Instead of USB Redirection
Real-Time Audio-Video supports webcam and audio input redirection for use in conferencing applications.
The USB redirection feature that can be installed with View Agent does not support webcam redirection. If
you redirect audio input devices through USB redirection, the audio stream does not synchronize properly
with video during Real-Time Audio-Video sessions, and you lose the benefit of reducing the demand on
network bandwidth. You can take steps to ensure that webcams and audio input devices are redirected to
your desktops through Real-Time Audio-Video, not USB redirection.
If your desktops are configured with USB redirection, end users can connect and display their locally
connected USB devices by selecting the Connect USB Device option in the VMware Horizon View Client
menu bar.
If an end user selects a USB device from the Connect USB Device list, that device becomes unusable for
video or audio conferencing. For example, if a user makes a Skype call, the video image might not appear or
the audio stream might be degraded. If an end user selects a device during a conferencing session, the
webcam or audio redirection is disrupted.
To hide these devices from end users and prevent potential disruptions, you can configure USB redirection
group policy settings to disable the display of webcams and audio input devices in
VMware Horizon View Client.
