This deployment guide is designed to provide guidelines for configuring the Cisco TelePresence Content Server and an external Wowza Media server for live and on demand Flash media streaming. These guidelines are for a Content Server running release 5.0.
The Content Server default installation supports only HTTP-based on demand hosting (also known as progressive download) of MPEG-4 for Flash content from its local IIS Web Server. An external Wowza Media server is required for live and on-demand streaming of MPEG-4 content for Flash.
The information presented here regarding the setup and configuration of your Wowza Media Server is offered as a guideline only and assumes that you are configuring the Wowza Media Server from a fresh install.
Further information regarding the setup and configuration of Wowza Media Server as well as information regarding more advanced configuration alternatives can be found in the Wowza Media support forums through the Wowza Media web site.
Step 5 Open the newly copied [install-dir]/conf/live/Application.xml. Make the following edits (see the “Example of XML Code: StreamType and Stream Properties” for the location of these parameters in the code):
c. Set the authentication method on the Wowza Media Server to digest (see the “Example of XML Code: Authentication” for the location of the authentication parameter in the code):
While there are no further changes required to the Wowza Media Server setup to have it stream media generated by the Content Server on-demand, there needs to be some way for the Content Server to get the media to the Wowza Streaming Server. The suggested method for this is FTP.
Ensure that you have an FTP service running on same server as your Wowza Media Server and that the FTP service has access to write into the [install-dir]/content folder on your Wowza Media Server. Please refer to the administration manual of your FTP service for details on how to accomplish this.
The following steps will create a new media server on the Content Server with support for live and on demand streaming through Wowza Media Server. If you only require support for one type of streaming, follow the steps as applicable to create a live streaming only or on-demand only media server.
Step 3 Enter a name for your new media server, and enter the server address, Check the type of streaming you want to support. You can check Support live unicast streaming or Support on demand or both. When you check either options, more configuration settings appear.
a. Enter a Streaming port range start value that is an even port number between 10000 and 65000. The Content Server will use a range of 30 ports beginning at this port number for streaming live calls.
b. Enter the user credentials you created in Step 6 of the Configure for live streaming in Wowza Media Server Configuration above.
You should choose to use alternate live URLs only if you know the live streaming URLs for the Wowza Media Server require different path or filename information to that generated by the Content Server.
- Enter the FTP server IP address under Server address.
- The standard FTP port is 21.
- If you leave the Directory field blank then the media will be placed in the root folder of the FTP server.
- Ensure that the account used for the FTP user has write privileges to the FTP server.
Now that you have created a media server which supports streaming of Flash from a Wowza Media Server, you need to use this media server in a Content Server template. Multiple templates can use the same media server.
Now that you have a template that is set up for streaming from a Wowza Media Server, you need to create a recording alias on the Content Server that uses this template. Multiple recording aliases can use the same template.
