Identifying stream formats

Identify the format or formats of the content by either identifying the source file or files to be streamed or by identifying the appropriate stream format file from Windows Media Encoder. The encoder system administrator can provide you with the stream format file.

All the stream formats used in your multicast session must be identified either by locating the Windows Media file or by locating the stream format file provided by the encoder. To identify the stream formats do the following:

• Click Add to open the Add Stream Formats dialog box.

• In the Location of content text box, type the path or browse to the stream format file (if you are streaming content from an encoder) or to the source file or files (if you are not streaming from an encoder).

• Select multiple files by using ctrl-click in the Browse window or by clicking Add after each file is selected. After all of the files have been added click OK.

• The selected files are displayed in the list on the Stream Formats page. If any have been inadvertently added, click Remove to remove them from the list.

Stream formats contain information a player needs to decode a stream, including codecs, bit rates, and frame sizes. If your content was encoded using different codecs, bit rates, frame sizes, and so on, ensure that you add each type of content to the stream format list. If you need to change the list of stream formats after creating an announcement for a multicast stream, you can run the announcement wizard again to create a new multicast information file. You are not required to create a new announcement.

Click Remove to delete a stream format from the list.
