Playlist Object Creation for On-Demand Publishing Points
The server always creates a Wrapper Playlist Object for an on-demand publishing point, but the way you configure the publishing point determines whether the server also creates a Requested Playlist Object. The configuration also determines how the server populates the playlist objects.
The following table identifies the playlist objects that are created for a variety of on-demand publishing point configurations. Parentheses indicate examples.
Note
A URL used by a client to connect to the server can contain the * wildcard character followed by a file name extension. To process these, you must enable the WMS Directory Playlist Parser. The list of file name extensions in the following table is not comprehensive. For example, if an MPG video parser plug-in is added to the server, the server can process *.mpg, but this is not indicated in the table.
