Value that represents the script command for this header
script. This value is the actual script command text and is processed
according to the syntax required by the ScriptType
value. There
is no built-in command execution in LEADTOOLS Multimedia or Windows Media
SDK. It
is up to the multimedia application to determine how to implement script
command execution and processing.
As an example, for a script type of "url" the application expects the script command to be a fully qualified URL, which should be opened in a browser.
