VirtualKeys

This tag sets the virtual key mappings for the different versions of Flash Player connecting to 
Flash Media Server. This tag and the 

VirtualDirectory

 tag implement the custom stream 

delivery feature in Flash Media Server 2.

Description

When the Flash Player running on a client connects to Flash Media Server, it receives a virtual 
key. This tag sets up which Flash Player versions are mapped to a particular key. A range of 
Flash Player versions is matched according to the 

FlashVer

 string that the player 

automatically sends to the server.

<VirtualKeys>

<Key from="WIN 8,0,0,0" to="WIN 9,0,0,0">A</Key>
<Key from="WIN 6,0,0,0" to="WIN 7,9,9,9">B</Key>
<Key from="MAC 6,0,0,0" to="MAC 7,0,55,0">B</Key>

</VirtualKeys>

This example shows how the key can be set by the administrator as a client property in the 
server-side script. If the client has key A, the 

Key

 attribute will map to on2, and if it has key B 

it will map to Sorenson.

<VirtualKeys from="WIN 7,0,19,0" to="WIN 9,0,0,0">A</VirtualKeys>

This example shows if the 

VirtualKey

 tag is not specified for a version of Flash Player, Flash 

Media Server applies a default setting.

Additional information

Custom stream delivery is enabled using a combination of the 

VirtualDirectory

 and 

VirtualKey

 tags, and the

 Client.virtualKey

 and 

Stream.setVirtualPath() 

APIs.

Application.xml file

The Application.xml file contains the settings for the applications that will run on the server. 
These settings include, for example, the size of the Server-Side Media ActionScript runtime 
engine, the location at which streams and shared objects are stored, and bandwidth 
limitations.
