Streaming Flash content directly from Adobe Media Server to client endpoints lowers the load on the datacenter ESXi host, removes the extra routing through the datacenter, and reduces the bandwidth required to simultaneously stream live video events to multiple client endpoints.

The Flash URL redirection feature uses a JavaScript that is embedded inside a Web page by the Web page administrator. Whenever a virtual desktop user clicks on the designated URL link from within a Web page, the JavaScript intercepts and redirects the ShockWave File (SWF) from the virtual desktop session to the client endpoint. The endpoint then opens a local VMware Flash Projector outside of the virtual desktop session and plays the media stream locally. Both multicast and unicast are supported.

This feature is available when used in conjunction with the correct version of the agent software. For View 5.3, this feature is included in the Remote Experience Agent, which is part of the View Feature Pack. For View 6.0 and later releases, this feature is included in View Agent or Horizon Agent.

To use this feature, you must set up your Web page and your client devices. Client systems must meet certain software requirements:

  • This feature is supported for PCoIP only. This feature is not supported on ARM processors.

  • Client systems must have IP connectivity to the Adobe Web server that hosts the ShockWave File (SWF) that initiates the multicast or unicast streaming. If needed, configure your firewall to open the appropriate ports to allow client devices to access this server.

  • Client systems must have the appropriate Flash plug-in installed.

    1. Install the libexpat.so.1 file, or verify that this file is already installed.

      Ensure that the file is installed in the /usr/lib or /usr/local/lib directory.

    2. Install the libflashplayer.so file, or verify that this file is already installed.

      Ensure that the file is installed in the appropriate Flash plug-in directory for your Linux operating system.

    3. Install the wget program, or verify that the program file is already installed.

  • libffi.so.5 is required on Ubuntu 14.04 to make Flash URL redirection work, but Ubuntu 14.04 has only libffi.so.6 by default. You can work around this limitation by making a symbolic link between libffi.so.6 and libffi.so.5.

For a list of the remote desktop requirements for Flash URL redirection, and for instructions about how to configure a Web page to provide a multicast or unicast stream, see the View documentation.
