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.

engine, the location at which streams and shared objects are stored, and bandwidth
limitations.
