Dell Wyse ThinOS Version 8.5 Hotfix Administrator’s Guide

Flash Redirection

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
   1. 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 newly added INI parameters are:

   SessionConfig=ICA\
   HDXFlashUseFlashRemoting=Never | Always (default) \
   HDXFlashEnableServerSideContentFetching=Disabled (default) | Enabled \

   How to verify it is working or not working

   1. Right-click the flash video to know the flash player version. It displays version information of the customized player at ThinOS client side which is 11.1.102.59. If the flash player version is different, then it is unsuccessful server rendering.

   2. During the flash playback, it will display ThinOS event logs for HDX FR in the System Information dialog box.

      1. FR: Media type video/x-264

      2. FR: Media type audio/mpeg

         

   For information about basic operations on Citrix HDX flash redirection and policies configurations, see Citrix documentation.
