Thread: Receive UDP multicast in wowza

    Default Receive UDP multicast in wowza

    Hello everyone

    I have been trying and trying and cannot get a clear hint of why what i am doing is not working.

    - I installed the wowza server
    - transmiting a video to a multicast ip address from another host
    - On a computer with vlc i can reproduce the video using udp://@multicastip:6000 that is being transmitted to the multicastip

    All three devices (wowza, host transmiting and computer with vlc) are in the same broadcast domain.

    - on the server i have configured
    a stream file, with URI udp://multicastip:6000 and link it to application live
    - when i go to incoming streams i can see ACTIVE
    - if I go into

    Network Throughput

    Bytes In: 0 @ 0.000 bits/s

    Bytes Out: 0 @ 0.000 bits/s

    I do not see any data transfer

    - if I go to TEST PLAYERS , Adobe RTPM , start
    i receive a status of playing but nothing shows up on screen


    Source stream or file could not be found or access was denied.



    with netstat i see a UDP session established between the wowza server and the multicastip on port 6000

    Can someone please indicate what am I doing wrong ?

    Are you using a single ethernet card in your system or multiple? If multiple, you may need to specify the interface in your VHost.xml file as shown in the following article:

    How to listen to multicast on a specific ethernet interface?

    Do you have any firewall software that could be blocking UDP port 6000?

    What operating system are you using?

    Best regards,
