How to re-stream an unprotected stream from Adobe Media Server or a CDN

This tutorial provides the basic steps for re-streaming an Adobe Media Server stream that supports H.264 and AAC through a Wowza™ media server. Use this tutorial to set up an application named live to stream live content to Adobe Flash Player, Microsoft Silverlight player, Apple iOS devices, and RTSP/RTP-based players.

Configuration

1. Create application folder [install-dir]/applications/live.
    
2. Create configuration folder [install-dir]/conf/live and copy [install-dir]/conf/Application.xml to this new folder.
    
3. Edit the newly copied Application.xml file and make the following changes (some of these settings may already be present):
    
   1. Set the Streams/StreamType property to:

      <StreamType>live</StreamType>

   2. Set the HTTPStreamers property to:

      <HTTPStreamers>cupertinostreaming,smoothstreaming,sanjosestreaming</HTTPStreamers>

   3. Set the Streams/LiveStreamPacketizers property to:

      <LiveStreamPacketizers>cupertinostreamingpacketizer,smoothstreamingpacketizer,sanjosestreamingpacketizer</LiveStreamPacketizers>

   4. Set the RTP/Authentication/PlayMethod property to:

      <PlayMethod>none</PlayMethod>

   5. Add the following property to the MediaCaster/Properties container (be sure to get the correct <Properties> container, there are several in the Application.xml file):

      <Property>
      	<Name>callFCSubscribe</Name>
      	<Value>true</Value>
      	<Type>Boolean</Type>
      </Property>

Publishing the stream

1. Use a text editor to create the file [install-dir]/content/rtmp.stream and set the contents of this file to the full RTMP URL of the stream that you want to re-stream (for example: rtmp://cp12345.live.edgefcs.net/live/myStream@2440). The file must have a .stream filename extension.
    
2. Using a text editor, edit the file [install-dir]/conf/admin.password and add a username and password that will be used to start and stop the publishing of the stream (below is an example of the file with the username myuser and password mypassword):

   # Admin password file (format [username][space][password])
   # username password
   myuser mypassword

3. Start the Wowza media server.
    
4. Use Stream Manager to start the stream:
    
   1. Enter the following URL in a web browser:
      URL: http://[wowza-ip-address]:8086/streammanager
   2. In the Security dialog box, enter your admin username and password from above.
       
   3. In the Stream Manager webpage, click the [start-receiving-stream] link just below the live application folder.
       
   4. In the Start Receiving Stream dialog box, select the following MediaCaster Type option: liverepeater
       
   5. In the Stream Name field, enter rtmp.stream.
       
   6. Click OK.

Troubleshooting

RTSP/RTP

• RTSP/RTP streaming is used to stream to Android and BlackBerry mobile devices. Newer Android-based phones also support Adobe Flash Player 10.1 and later, along with RTMP and Adobe HTTP Dynamic Streaming (Adobe HDS).
• To stream to RTSP/RTP, be sure that UDP ports 0-65535 are open and properly mapped to the server running Wowza Media Server.
• It's very important to carefully follow the instructions provided in How to troubleshoot RTSP/RTP playback to properly configure Wowza Media Server for RTSP/RTP streaming.

Wowza Streaming Engine Manager configuration

1. In Wowza Streaming Engine Manager, click the Applications tab and then click the name of your live application (such as live) in the contents panel.
    
2. On the live application page Properties tab, click Custom in the Quick Links bar or scroll to the bottom of the page.
    
   Note: Access to the Properties tab is limited to administrators with advanced permissions. For more information, see Manage credentials.
3. In the Custom area, click Edit.
    
4. Click Add Custom Property, specify the following settings in the Add Custom Property dialog box, and then click Add:
    
   • Path: Select /Root/Application/RTP.
      
   • Name: Enter audioPacketizerAAC.
      
   • Type: Select String.
      
   • Value: Enter com.wowza.wms.rtp.packetizer.RTPPacketizerMPEG4LATM.
5. Click Save, and then restart the live application to apply the changes.

XML configuration

1. Use a text editor to open the [install-dir]/conf/[application]/Application.xml file for your live application and add the following property to the RTP/Properties container. Be sure to add the property to the correct <Properties> container in Application.xml as there are several such containers in the file.

   <Property>
       <Name>audioPacketizerAAC</Name>
       <Value>com.wowza.wms.rtp.packetizer.RTPPacketizerMPEG4LATM</Value>
   </Property>

2. Restart the Wowza media server software to apply the changes.
