Internal Script Command Renderer Filter

Receives script commands and dispatches them to the application.

This filter accepts script commands in one of two formats:

• MEDIATYPE_Text: Each media sample contains an ANSI text string.
• MEDIATYPE_ScriptCommand: Each media sample contains two NULL-terminated Unicode™ strings, concatenated together. The first string describes the command type and the second string is the script command.

  When the filter receives a sample, it sends an EC_OLE_EVENT event notification. The first event parameter is a BSTR with the command type, or Text if the format is MEDIATYPE_Text. The second event parameter is a BSTR with the script command. The application can retrieve the event and respond to the script command.

For an example of how to use this filter, see SAMI (CC) Parser.
