The Real-Time Audio-Video (RTAV) group policy settings control the virtual webcam's maximum frame rate and maximum image resolution. An additional setting lets you disable or enable the RTAV feature. These policy settings affect remote desktops, not the client systems where the physical devices are connected.

If you do not configure the RTAV group policy settings, RTAV uses the values that are set on the client systems. On client systems, the default webcam frame rate is 15 frames per second. The default webcam image resolution is 320x240 pixels.

The resolution group policy settings determine the maximum values that can be used. The frame rate and resolution that are set on client systems are absolute values. For example, if you configure the RTAV settings for maximum image resolution to 640x480 pixels, the webcam displays any resolution that is set on the client up to 640x480 pixels. If you set the image resolution on the client to a value higher than 640x480 pixels, the client resolution is capped at 640x480 pixels.

Not all configurations can achieve the maximum group policy settings of 1920x1080 resolution at 25 frames per second. The maximum frame rate that your configuration can achieve for a given resolution depends upon the webcam being used, the client system hardware, the Horizon Agent virtual hardware, and the available bandwidth.

The resolution group policy settings determine the default values that are used when resolution values are not set by the user.

Group Policy Setting

Description

Disable RTAV

When you enable this setting, the Real-Time Audio-Video feature is disabled.

When this setting is not configured or disabled, Real-Time Audio-Video is enabled.

This setting is in the VMware View Agent Configuration > View RTAV Configuration folder in the Group Policy Management Editor.

Max frames per second

Determines the maximum rate per second at which the webcam can capture frames. You can use this setting to limit the webcam frame rate in low-bandwidth network environments.

The minimum value is one frame per second. The maximum value is 25 frames per second.

When this setting is not configured or disabled, no maximum frame rate is set. Real-Time Audio-Video uses the frame rate that is selected for the webcam on the client system.

By default, client webcams have a frame rate of 15 frames per second. If no setting is configured on the client system and the Max frames per second setting is not configured or disabled, the webcam captures 15 frames per second.

This setting is located in the VMware View Agent Configuration > View RTAV Configuration > View RTAV Webcam Settings folder in the Group Policy Management Editor.

Resolution - Max image width in pixels

Determines the maximum width, in pixels, of image frames that are captured by the webcam. By setting a low maximum image width, you can lower the resolution of captured frames, which can improve the imaging experience in low-bandwidth network environments.

When this setting is not configured or disabled, a maximum image width is not set. RTAV uses the image width that is set on the client system. The default width of a webcam image on a client system is 320 pixels.

The maximum limit for any webcam image is 1920x1080 pixels. If you configure this setting with a value that is higher than 1920 pixels, the effective maximum image width is 1920 pixels.

This setting is located in the VMware View Agent Configuration > View RTAV Configuration > View RTAV Webcam Settings folder in the Group Policy Management Editor.

Resolution - Max image height in pixels

Determines the maximum height, in pixels, of image frames that are captured by the webcam. By setting a low maximum image height, you can lower the resolution of captured frames, which can improve the imaging experience in low-bandwidth network environments.

When this setting is not configured or disabled, a maximum image height is not set. RTAV uses the image height that is set on the client system. The default height of a webcam image on a client system is 240 pixels.

The maximum limit for any webcam image is 1920x1080 pixels. If you configure this setting with a value that is higher than 1080 pixels, the effective maximum image height is 1080 pixels.

This setting is located in the VMware View Agent Configuration > View RTAV Configuration > View RTAV Webcam Settings folder in the Group Policy Management Editor.

Resolution - Default image resolution width in pixels

Determines the default resolution width, in pixels, of image frames that are captured by the webcam. This setting is used when no resolution value is defined by the user.

When this setting is not configured or disabled, the default image width is 320 pixels.

The value that is configured by this policy setting takes effect only if both View Agent 6.0 or later and Horizon Client 3.0 or later are used. For older versions of View Agent and Horizon Client, this policy setting has no effect, and the default image width is 320 pixels.

This setting is located in the VMware View Agent Configuration > View RTAV Configuration > View RTAV Webcam Settings folder in the Group Policy Management Editor.

Resolution - Default image resolution height in pixels

Determines the default resolution height, in pixels, of image frames that are captured by the webcam. This setting is used when no resolution value is defined by the user.

When this setting is not configured or disabled, the default image height is 240 pixels.

The value that is configured by this policy setting takes effect only if both View Agent 6.0 or later and Horizon Client 3.0 or later are used. For older versions of View Agent and Horizon Client, this policy setting has no effect, and the default image height is 240 pixels.

This setting is located in the VMware View Agent Configuration > View RTAV Configuration > View RTAV Webcam Settings folder in the Group Policy Management Editor.
