Citrix Virtual Apps and Desktops


High definition webcam streaming

Webcams can be used by video conferencing applications running within the virtual session. The application on the server selects the webcam format and resolution based on the supported format types. When a session starts, the client sends the webcam information to the server. Choose a webcam from the video conferencing application. When the webcam and the application both support high-definition rendering, the application uses high-definition resolution. We support webcam resolutions up to 1920x1080.

This feature requires the Citrix Receiver for Windows, minimum version 4.10. For a list of Citrix Workspace app platforms that support HDX webcam redirection, see Citrix Workspace app feature matrix.

For more information about high definition webcam streaming, see HDX video conferencing and webcam video compression.


Editing the registry incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of the Registry Editor can be solved. Use the Registry Editor at your own risk. Be sure to back up the registry before you edit it.

You can use a registry key to disable the feature. The default resolution of 352x288 is used:
