    Default SDP file issue

    Dear Wowza support team,
    I have a streamer in VLC can view but can not in WMS.
    The content of myStream.sdp is as follows.
    code:
    v=0
    o=- 3822851562 1443973 IN IP4 10.254.59.19
    s=525 Nat Geo Wild (1)
    c=IN IP4 239.1.1.1/64
    t=0 0
    a=min-buffer-time:5004
    a=range:npt=now-
    m=video 53000 RTP/AVP 96
    b=AS:245
    b=TIAS:236580
    b=RS:3000

    What encoder are you using? Did it generate this .sdp file?

    Might you be able to re-stream over udp following this mpeg-ts guide

    Did you try the method in the mpeg-ts guide using udp url and .stream file? Just noting that the IP is 239.x.x.x address which is a multicast address.

    I think you have to change this line:

    c=IN IP4 239.1.1.1/64

    To the IP address of the encoder.
