If an administrator has configured the Real-Time Audio-Video feature, you can use the client machine's audio-video devices in a remote desktop or published application. Real-Time Audio-Video is compatible with standard conferencing applications and browser-based video applications, and it supports standard webcams, audio USB devices, and analog audio input.

Real-Time Audio-Video is supported only in Chrome, Microsoft Edge, and Firefox. The default video resolution is 320 x 240 pixels. The default Real-Time Audio-Video settings work well with most webcam and audio applications.

Note: Browsers on iOS do not support Real-Time Audio-Video.

For information about changing the Real-Time Audio-Video settings, see "Configuring Real-Time Audio-Video Group Policy Settings" in the Horizon Remote Desktop Features and GPOs document.

When a remote desktop or published application is connected to the client machine's audio-video device, before the remote desktop or published application can use the device, the browser might ask for permission. Different browsers behave differently.

When a remote desktop is connected to the client machine's audio-video device, an icon for each device appears at the top of the sidebar. A red question mark appears over the device icon in the sidebar to indicate the permission request. If you allow a device to be used, the red question mark disappears. If you reject a permission request, the device icon disappears.

If Real-Time Audio-Video is being used in a remote desktop or published application session and you open a connection to a second remote desktop or published application, and if a security warning appears (for example, if a valid certificate was not installed), ignoring the warning and continuing to connect to the second remote desktop or published application causes Real-Time Audio-Video to stop working in the first session.
