    Unhappy MPEG-TS UDP Multicast Woes

    So I've attempted to set up my broadcast encoder to push 4 Mbit/sec UDP multicast to 224.2.2.2:10000 on my internal network. I configured Wowza following this tutorial http://www.wowza.com/forums/content.php?37, entering the multicast IP instead of 0.0.0.0 as indicated. All else is the same. There does not appear to be any output from the Wowza Server (as in http://[wowza-ip-address]:1935/live/.../playlist.m3u8 and http://[wowza-ip-address]:1935/live/...m/manifest.f4m do not exist), and I'm at a point where I'm banging my head against a wall here.

    Sample output from my logs...

    Hello,

    You mentioned that you are using the encoder to push the multicast stream pn your internal network.
    I see from the logs that your Wowza server is using an Amazon EC2 server.
    I don't think that you will be able to push your multicast stream from your local network to your Amazon server. You should have your Wowza server in the same network as your multicast encoder.

    This log line, also indicated that the encoder stream is not reaching Wowza server:

    Hello Zoran,

    I do not understand why the Amazon messages are there. I am not using an EC2 server. This is a local hard box on my local LAN. Looking at it right now. Made of metal. IP of 192.168.41.102. All I did was install Wowza from the website and configure it as per the above tutorial (adding my license key of course). Download was from here http://www.wowza.com/downloads/Wowza...-3.6.2.deb.bin

    Also, to answer your other point, there is SOMETHING reaching the server. Here is the relevant output of tshark from that server.

    Those are the UDP multicast packets from the encoder.

    EDIT: added mpegts.stream contents

    udp://224.2.2.2:10000
    EDIT AGAIN:
    Since it's not incredibly obvious from the tshark output, here's the tcpdump output showing destination port:

    can you create a .zip archive of your Wowza conf/ and logs/ folders and send them to support@wowza.com ?
    Please add this forum URL as reference. I would like to take a closer look at your logs.

    By the way, do you have more than one network interface configured on your server?

    I have sent you the requested files, plus my transcoder folder (JIC).

    Yes, I do have two interfaces on this box. As you can see from the file, I did make sure to clarify for Wowza (using the instructions http://www.wowza.com/forums/showthre...ed=1#post85796 and here http://www.wowza.com/forums/content....work-interface, seemingly to no avail.

    Jasonritzke,
    I came here to find a solution to such a scenario. Incidentally, your setup is similar to mine except that your Wowza and encoder are on the same network (are you sure?). So let me try to help you...

    While your issue looks more of a network and firewall related, make sure your stream being published is H264-mpeg+AAC.
    I would do the following to troubleshoot this problem:

    1. Disable firewall on the Debian
    2. Disable firewall on the encoder
    3. Use VLC player to stream to Wowza (debian), use lower bitrates and formats just to test, in your case the publish as UDP legacy to IP 224.2.2.2 and port 10000
    4. Use VLC player on yet another computer on the network to play RTMP stream from Wowza
    5. If this works, there is no issue in networking, the problem is with your encoder or player settings.
    6. If it doesn't, VLC player on the player side will show some message if it is unable to play, something like "the video is not encoded with MP4" or "Could not connect to server" or something, i don't recall the exact syntax. That would be your hint to encoding or connectivity problems. You should be able to find a direction from there on.

    oh by the way, I had to append mp4 to stream name in jwplayer once, in case you're using that, i.e, rtmp://YourWowzaIp:1935/streamname/mp4:mpegts.stream

    Best wishes
