HTML5 Video Redirection
HTML5 Video Redirection controls and optimizes the way Citrix Virtual Apps and Desktops servers deliver HTML5 multimedia
web content to users. This feature is available for internal web pages only. It requires the addition of JavaScript to the web
pages where the HTML5 multimedia content is available, for example, videos on an internal training site.
The following policies must be enabled on the server side:
● Windows Media redirection—By default this option is enabled.
● HTML5 video redirection—By default this option is disabled.
For more information about the ICA Multimedia policy settings, see the Citrix documentation at docs.citrix.com.
For information about how to verify if HTML5 Video Redirection is working, see the FAQs section in this guide.
