    Question Livestreaming lot of delay

    Hello Everyone,

    It's my first post on this forum.

    We have two servers with identical characteristics.

    MacOS 64bits on one and Debian 7 64bits on the other.

    Wowza configurations are identical.

    On the MacOS live opens quickly (less than 3-4s).

    On the Debian live opens after 12-14s.

    In MacOS server logs I noticed that RTPUDPTransport.bind and / or UDPTransport.firstPacket take 1s.

    In Debian server logs I noticed that RTPUDPTransport.bind and / or UDPTransport.firstPacket take 10s.

    What is the problem?

    I try to tune Wowza but nothing changes.

    I'm sorry but I don't know how to join a file so I copy the logs here.

    Thank you,

    Hi NicolasVTSYS, and welcome to Wowza Forum!

    Wowza normally connects to the RTSP stream via UDP, but if this is somehow blocked (for example, a firewall setting), it would then switch to TCP, which takes around 10 seconds or so. Please test your Debian server again, but this time, turn off the firewall (just for testing purposes), and let us know if you still see the same issue.
