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.
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.
- Microsoft Edge asks for permission every time. You cannot change this behavior. For more information, see https://blogs.windows.com/msedgedev/2015/05/13/announcing-media-capture-functionality-in-microsoft-edge.
- Firefox asks for permission every time. You can change this behavior. For more information, see https://support.mozilla.org/en-US/kb/permissions-manager-give-ability-store-passwords-set-cookies-more?redirectlocale=en-US&redirectslug=how-do-i-manage-website-permissions.
- Chrome asks for permission the first time. If you allow the device to be used, Chrome does not ask for permission again.
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.
