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

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

The Flash URL redirection feature is available only when the correct version of the agent software is installed. This feature is included in the agent software beginning with View Agent 6.0.

To use the Flash URL redirection feature, you must set up your Web page and the client devices. Client systems must meet the following 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 application, or verify that the application file is already installed.

  • libffi.so.5 is required on Ubuntu 14.04 and 16.04 distributions to make the Flash URL redirection feature work, but Ubuntu 14.04 and 16.04 distributions only have libffi.so.6 by default. You can work around this limitation by making a symbolic link between libffi.so.6 and libffi.so.5.
