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.
• ThinWire Plus—Equivalent to Do not use video codec option
• Fullscreen H.264—Equivalent to For the entire screen option
• Selective H.264—Equivalent to For actively changing regions
Verifying the working status of the ICA connections—ICA SuperCodec is always enabled without any limitation. The following
ThinOS event log is displayed:
ICA: SuperCodec enabled
NOTE:
For ICA connections, there is no INI parameter.
If you set the Use video codec for compression policy to Do not use video codec, ICA SuperCodec is disabled, and
ThinOS does not print any log.
Anonymous logon
Anonymous logon feature enables the users to log into the StoreFront server configured with unauthenticated store without Active
Directory (AD) user credentials. It allows unauthenticated users to access the applications instead of AD accounts.
NOTE:
Anonymous logon is not supported with legacy mode of StoreFront server.
