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.

settings/multimedia-policy-settings.html.
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 show the image on screen. It should improve
user experience especially for HDX3DPro desktops.
Supported environment
XenDesktop and XenApp 7.5 or later versions
Supported platforms
All the ThinOS 8.5-based devices support ICA SuperCodec.
Verifying the working status of the ICA connections
● For Wyse 3010 with ThinOS (T10) and Wyse 3020 with ThinOS (T10D)
ICA SuperCodec is enabled by default when ThinOS resolution is lesser than or equal to 1920 x 1080.
1. When the feature is working, the following results are displayed:
ThinOS event log ICA: SuperCodec enabled
Click HDX Monitor > Graphics > Thinwire advanced > Encoder: DeepCompressionV2Encoder for NON-HDX3DPro
desktops or DeepCompressionEncoder for HDX3DPro desktops.
From XenDesktop/ XenApp 7.11, the Encoder is changed to Deprecated.
