    Wowza Media Server includes a feature for configuring streams that are publish/started at server startup. This is the equivalent of starting a streaming using the MediaCaster Stream Manager. To configure a stream to start at server startup do the following:

    1. Edit [install-dir]/conf/StartupStreams.xml and add a <StartupStream> entry for each stream you wish to have started at server startup. Here are a few examples:

      RTSP/RTP example (RTSP URL is rtsp://192.168.1.7:554/mycoolstream.sdp):
      Code:
      <StartupStream>
	<Application>live/_definst_</Application>
	<MediaCasterType>rtp</MediaCasterType>
	<StreamName>rtsp://192.168.1.7:554/mycoolstream.sdp</StreamName>
</StartupStream>
      Native RTP example (SDP file is myStream.sdp):
      Code:
      <StartupStream>
	<Application>live/_definst_</Application>
	<MediaCasterType>rtp</MediaCasterType>
	<StreamName>myStream.sdp</StreamName>
</StartupStream>
      SHOUTcast example (SHOUTcast URL is http://mycompany.com/station1):
      Code:
      <StartupStream>
	<Application>live/_definst_</Application>
	<MediaCasterType>shoutcast</MediaCasterType>
	<StreamName>http://mycompany.com/station1</StreamName>
</StartupStream>
      Using a .stream file to simplify MPEG-TS stream (myStream.stream is text file with contents udp://0.0.0.0:10000):
      Code:
      <StartupStream>
	<Application>live/_definst_</Application>
	<MediaCasterType>rtp</MediaCasterType>
	<StreamName>myStream.stream</StreamName>
</StartupStream>

      Can I use?

      <StreamName>http://primary.server/stream|http://backup.server/stream</StreamName>

      If yes, how is the logic of going to backup server?

      Hi toti171,

      Those stream URIs don't seem valid. See the QuickStartGuide for examples. Also see the Live Repeater Quickstart if you are trying to do an Origin-Edge configuration.

      I´m sorry.. I wasn´t clear

      What I want to do, is have the signal started on server boot, but with a backup server in case of some unavailability.

      <StreamName>rtmp://[wowza-origin-address]:1935/liveorigin|rtmp://[wowza-alternate-origin-address]:1935/backuporigin</StreamName>

      Thanks

      You can do that with the Wowza liverepeater by include a pipe separated string just like you have in the Application.xml /originURL

      Another method is to use .stream files or StreamNameAlias alias and have pipe separated origin stream URLs that include the stream name, like this:

      File: /content/origin.stream
      Contents: rtmp://[wowza-origin-address]:1935/liveorigin/myStream|rtmp://[wowza-alternate-origin-address]:1935/backuporigin/myStream

      Hi all,

      I have a question:
      If I have many .stream file in some folders, like this:
      File1: /content/a/a1.stream
      File2: /content/a/a2.stream
      File3: /content/a/a3.stream
      File4: /content/b/b1.stream
      File5: /content/b/b2.stream
      File6: /content/b/b3.stream
      ...

      I want to publish all, what can I do?
      Thanks!

      Use /conf/StartUpStreams.xml, which is linked at top of this thread
      http://www.wowzamedia.com/forums/con...upStreams.xml)

      This will start stream on startup. If you want to do at another time, all at once, you can use the MediaCaster API

      Thank Richard,

      I use /conf/StartUpStreams.xml to publish 32 .stream files.
      Firstly, everything works fine, but after java crashes with the exception :"java.lang.OutofMemeory Error: Java heap space"

      Can you help me,
      Thanks,

      Make sure you are properly tuned:
      http://www.wowza.com/forums/content....ormance-tuning

      The limiting factor for incoming streams is ram and cpu (for outgoing streams the usual limiting factor is bandwidth). To handle 32 streams you should have a late model quad or dual quad cpu, 4 - 8g ram, 64bit OS and 64bit Java latest JDK.

      Thank you so much, Richard!

      I have another question:
      I want to publish 10 HD channels (8bitrates/ channel) and using origin-edge application (1 origin server and 2 edge servers).But my origin server is not enough ram and cpu. If I use many origin, one origin for some different channels, does it work?

      Thanks,
    1. rrlanham - 09-04-2012, 06:41 AM
      You can have as many origin servers as you want. An edge server can re-stream from many sources by using .stream files on edge servers to refer to origin streams. This technique ignores the Application.xml /originURL setting. Take a look at this guide:
