Removing all Stream XML files
All XML files can be removed from the Web Presenter by sending the stream xml command with
the remove all action. In the example, following the remove all action, the loaded stream XML
files and available custom platforms are both displayed as empty.

Stream State Block
The stream state block provides the streaming status of the Web Presenter.
The Web Presenter server will send a stream state block update whenever there is a change to
the Status field. Due to frequency of changes to Duration and Bitrate fields, these fields need to
be polled by the client by requesting a Stream State block.
