HTML5 Video Redirection
HTML5 Video Redirection controls and optimizes the way XenApp and XenDesktop servers deliver HTML5 multimedia web
content to users. From XenApp and XenDesktop 7.12, 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 server policies must be enabled:
● Windows Media redirection—By default this option is enabled.
● HTML5 video redirection—By default this option is disabled.
Verifying HTML5 Video Redirection—While the video is playing, a noticeable lag or jump in the video window is observed
when you move the browser on the screen or scroll the browser. This behavior indicates that the video is being redirected.
ThinOS event log for RAVE MMR is also displayed.
Sometimes, the initial playback does not work. After several seconds, the video is refreshed automatically, and you need to click
playback from start again. During this time, the video will redirect.

ICA SuperCodec
ICA SuperCodec is a H.264 decoder integrated on ThinOS ICA client side. Server encodes the session image into H.264 stream
and sends it to client side. Client decodes the H.264 stream by SuperCodec and display the image on screen. This feature
improves user experience especially for HDX 3D Pro desktops.
Supported Environment
Citrix Virtual Apps and Desktops (formerly XenDesktop) and Citrix Virtual Apps (formerly XenApp) version 7.5 or later versions
Prerequisities
In Citrix Virtual Apps and Desktops (formerly XenDesktop) and Citrix Virtual Apps (formerly XenApp) version 7.9 and later, the
default setting for Use video codec for compression is Use when preferred. For best performance on ThinOS device, Dell
recommends that you set the Use video codec for compression policy to For the entire screen. Alternatively, you can also
set the policy to Do not use video codec. This allows ThinOS to use ThinWire Plus that saves bandwidth and reduces CPU
overhead.
