Wowza Media Server Configuration
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.
Configure for Live Streaming
To set up your Wowza Media Server to accept live streaming of media from your Content Server, follow these steps:
Step 1 Create a new Wowza Pro application for live streaming by creating this directory:
Note [install-dir] is the install directory of the Wowza software.
Step 2 Create the folder: [install-dir]/applications/_defapp_
Step 3 Create the folder: [install-dir]/conf/live
Step 4 Copy the file [install-dir]/conf/Application.xml into the new folder [install-dir]/conf/live.
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):
a. Change Streams/StreamType to
b. Add the following properties to the Streams/Properties container:
Example of XML Code: StreamType and Stream Properties
c. Set the authentication method on the Wowza Media Server to
(see the “Example of XML Code: Authentication” for the location of the authentication parameter in the code):
Example of XML Code: Authentication
Step 6 Edit the file [install-dir]/conf/rtp.password (or [install-dir]/conf/publish.password if Wowza Media Server 2) and add a username and password.
# RTP password file (format [username][space][password])
Note The username and password shown above are examples only. You should ensure you use a secure username and password combination for your server installation.
Note The username and password are case sensitive. For the media server to function correctly, the same case must be used in the Content Server interface.
Step 7 If you are only setting up your Wowza Media Server for live streaming from your Content Server then startup the Wowza Media Server, otherwise move on to the next section.
Note Any changes you make to the configurations in Step 1 to Step 6 in the future will require a restart of the Wowza Media Server.
Configure for On-Demand Streaming
To set up your Wowza Media Server to stream on-demand media follow these steps:
Step 1 Create the folder [install-dir]/applications/vod to serve as the application folder.
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.
Note While the Wowza Media Server supports the recording of live streams at the server, this functionality is not supported by the Content Server.
Step 2 Start up the Wowza Media Server.
TelePresence Content Server Configuration
Now that your Wowza Media Server is configured for live and on-demand streaming, you need to set up the Content Server using that configuration information.
The steps for setting up your Content Server are described below:
Create a Media Server
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 1 From the Management tab menu, go to
Recording setup > Media server configurations
Step 2 Click the Add Wowza Media Server for Flash configuration link to create a new Wowza 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.
Step 4 If you checked
Support live unicast streaming
, complete the Live
unicast streaming settings
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.
Step 5 In most cases when setting up a new media server, it is recommended that you choose to Use default live URLs.
The default Application directory is live and should not require changing.
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.
Step 6 If you checked
Support on demand
media needs to be moved from the Content Server to the Wowza Media Server. The standard method for this is File Transfer Protocol (FTP).
From the On demand settings section, click FTP movies to location and enter the required FTP server information:
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.
Step 7 In the On Demand URLs section, it is recommended that you click
Use default on demand URLs
The default Application directory is vod and should not require changing.
You should enter alternate on-demand URLs only if you know the streaming server requires a different path or filename information to that generated by the Content Server.
Step 8 Click
Create a Template
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.
Step 1 From the Management tab, go to
Recording setup > Templates
Step 2 Click the Add Template link to create a new template.
Step 3 Enter a Name for your template.
Step 4 Check
Viewable in the Content Server web interface
Step 5 In the
Outputs to view in the Content Server web interface
section, click one of the viewing layouts.
Step 6 In the
section, do the following:
a. Click MPEG-4 for Flash from the formats available.
b. Click one or two options under Sizes (Audio only, Small, Medium, or Large).
Step 7 In the On demand media server configuration settings section, choose a media server that supports on-demand streaming from a Wowza Media Server.
Step 8 Check Live Stream if you want the call to be available for live streaming. Ensure that the format for live streaming chosen from the drop-down menu is MPEG-4 for Flash.
Step 9 In the Live media server configuration settings section, choose a media server that supports live streaming from a Wowza Media Server.
Step 10 Click
Create a Recording Alias
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.
Step 1 From the
tab, go to
Recording setup > Recording aliases
Step 2 Click the Add recording alias link to create a new recording alias.
Step 3 Enter a name for your recording alias, and click the recording alias type. If required, choose a personal recording alias owner.
Step 4 Enter the relevant dialing properties that conform to your dialing plan.
Step 5 Choose a suitable template that supports streaming Flash from a Wowza Media Server.
Step 6 Click
You have now configured the Content Server for streaming Flash from your Wowza Media Server. You should now make a test call on the recording alias you have created to verify your configuration.
