    Default Live unicast UDP Stream

    I am using Wowza for the first time, trail license, version is 4.1.2.
    Running on MAC OSX 10.9.5

    I have a Brightsign player, that is streaming a unicast stream using UDP.

    In Wowza, created a LIVE STREAM and set the STREAM FILES - STREAM URI to - udp://192.168.40.4:2234.

    I don't see anything under MONITORING, i.e. no traffic however under APPLICATION UPTIME it says

    BS-UNICAST-STREAM not running

    I clicked RESTART but nothing changes.

    I know the Brightsign player is sending out the stream because I captured packets using WireShark.

    Is it possible to ingest a unicast UDP stream ?
    I want to ingest it as noted and output a UDP multicast stream.

    Any assistance would be appreciated !

    Thanks

    Some progress....I now have the application receiving incoming traffic as seen under Monitor window.
    Within the application instance left all the PLAYBACK TYPES check.
    From the Monitor window using the TEST PLAYERS, Adobe RTMP, click START this message is displayed
    at the bottom of the window - "Source stream or file could not be found or access was denied"

    Thank you for any suggestions.

    Hello there.

    The first requirement is that the target network supports multicast. If so you would use the Push Publish AddOn:

    I decided to uninstall 4.1.2 version and install 4.2.

    Right now, I have things almost working, except no audio.

    I created two STREAM TARGETS, MPEG-TS and RTP.
    I can join either of these streams using VLC but no audio.

    If I stop the incoming stream (Unicast - udp://192.168.40.33:2234) I can use VLC to join the Unicast stream
    and I get both video and audio.

    The unicast stream is from a BirghtSign player and the product specs mentions "AUDIO - AAC and MPEG1 layer 2 (MP2) included with video".

    Searching FORUMS I have seen references to SDP files, since I am not familiar with these files, I have included both, perhaps something not setup correctly:

    MPEGTS SDP

    v=0
    o=- 1633595905 1633595905 IN IP4 127.0.0.1
    s=BS-UNICAST.stream
    t=0 0
    a=sdplang:en
    a=range:npt=now-
    a=control:*
    m=video 2234 RTP/AVP 33
    c=IN IP4 239.194.0.201/63
    a=rtpmap:33 MP2T/90000
    a=control:mpegts-transport

    RTP SDP

    v=0
    o=- 2061474279 2061474279 IN IP4 127.0.0.1
    s=BS-UNICAST.stream
    t=0 0
    a=sdplang:en
    a=range:npt=now-
    a=control:*
    m=audio 10004 RTP/AVP 96
    c=IN IP4 239.194.0.202/63
    a=rtpmap:96 mpeg4-generic/48000/2
    a=fmtp:96 profile-level-id=1;mode=AAC-hbr;sizelength=13;indexlength=3;indexdeltalength=3;config=1190
    a=control:trackID=1
    m=video 10002 RTP/AVP 97
    c=IN IP4 239.194.0.202/63
    a=rtpmap:97 H264/90000
    a=fmtp:97 packetization-mode=1;profile-level-id=42001F;sprop-parameter-sets=J0IAH5ZWAoAt3/gAAAMAAIAAAfQAAHUwT4RCKLA=,KMqOIA==
    a=cliprect:0,0,720,1280
    a=framesize:97 1280-720
    a=framerate:30.0
    a=control:trackID=2

    Much closer...jus need to get the audio working ???
    Thanks
