Flash Redirection
Flash Redirection
The Flash Redirection solution is to off-load flash content to the ThinOS client, and locally render and decode the flash playback. The off-
loading is conducted by Citrix HDX Flash Redirection. The local rendering and decoding process are conducted by customized flash player
and other multimedia process that runs locally on ThinOS.
Supported Environment—Supports only Citrix connections with Citrix Apps 6.5 and later versions and Citrix Apps and Desktops 7.0 and
later versions.
Required packages
User must install the FR.i386.pkg package for the feature to work:
Installation of packages
To install the required packages, follow the steps mentioned here:
1. Upload packages to directory \wnos\pkg\.
2. Ensure that the INI autoload is not set to 0. Set INI AutoLoad=1 AddPkg=FR in wnos.ini.
3. Restart the client to read the file server and wait till the auto installation of packages is complete.
You can view the installed packages in the Packages tab in the System Tools dialog box.
4. Server configuration for Flash redirection
a) To ignore the differences in flash player versions, user must add the FlashPlayerVersionComparisonMask and
ClientFlashPlayerVersionMinimum registry key on the desktop.
If it is Citrix Virtual Apps 6.5, IEBrowserMaximumMajorVersion registry key is required to ignore the differences in IE
Browser versions.
For more information, see docs.citrix.com/en-us/xenapp-and-xendesktop/7-9/hdx/flash-redirection.html.
From Citrix Virtual Apps and Desktops 7.9, you must add more entries in registry for HDX FR to work. For information about these
additional entries, refer to Citrix Technical documents.
5. Client configuration for Flash redirection
By default, no client configuration is required. New INI parameters are added to support HDX FR Client configurations, for example, to
fetch the server side content. The INI parameters are:
SessionConfig=ICA\
HDXFlashUseFlashRemoting=Never | Always (default) \
HDXFlashEnableServerSideContentFetching=Disabled (default) | Enabled \
How to verify it is working or not working
a. Right-click the flash video to know the flash player version. It displays version information of the customized player at ThinOS
client side. If the flash player version is different, then it is unsuccessful server rendering.
b. During the flash playback, the following ThinOS event logs is displayed in the System Information dialog box:
• FR: Media type video/x-264
• FR: Media type audio/mpeg
For information about basic operations on Citrix HDX flash redirection and policies configurations, see Citrix documentation.

Configuring VMware
VMware virtualization enables you to run multiple virtual machines on a single physical machine. VMware Horizon Client is a locally installed
software application that communicates between View Connection Server and thin client operating system. It provides access to centrally
hosted virtual desktops from your thin clients.
In every ThinOS release, the Horizon Client version may be updated to newer version. For information about the latest Horizon Client
version, see the latest Dell Wyse ThinOS Release Notes at www.dell.com/manuals.
NOTE:
If you are upgrading your thin client to the latest ThinOS version, you must ensure that the Horizon server or
agent version is updated to support the latest horizon client version. For more information about the client and server/
agent version compatibility, see the VMware Product Interoperability Matrices page at www.vmware.com.
