Retrieving stream format information
When you are pulling a stream from an encoder for a multicast broadcast, you need to provide the players with the information necessary to decode the stream. You have the following options for obtaining encoder stream format information:
Automatically retrieve stream formats from my encoder (suitable only when the encoder is running). Select this option to have the server connect to the encoder and retrieve the stream format file from the header information.
Manually select stream formats (recommended when the encoder is not running or when using an existing stream format). Select this option to locate a stream format file manually. If the encoder is not running, you must select this option.
