Thread: MPEG-TS from Cisco D9854

  1. #1

    Default MPEG-TS from Cisco D9854

    Hi,

    I'm trying to play stream from Cisco D9854 [decoder - multicast UDP] but with no sucess. Create a mpegts.stream with udp://0.0.0.0:10000 and with udp://ip:5001 - decoder ip, publish in stream manager, but i can't play.

    Nothing in logs. The UDP packets coming to interface.

    I tested a MPEG-TS in VLC and play ok.

    Regards,

    Guilherme

    I think you have to point the stream to the same server:

    udp://[wowza-address]:10000

    Then re-stream in Wowza from udp://0.0.0.0:10000 or udp://127.0.0.1:10000

    Hi Richard,

    I'm tried udp://127.0.0.1:10000 and udp://<wowza server>:10000.

    Wowza create the stream and detroy in seconds. It's a Linux box (virtual machine) with Wowza 3.1.0 build1410. I have 2 network interfaces: eth0 to access Wowza and eth1 to multicast (with multicast and promiscuos mode).

    Hi
    Wowza does this when it tries to play a stream and can't find it.
    You must have some multicast configurations wrong (a typo maybe or you're looking on the wrong port?).

    Try checking your configuration in the VHost.xml against this guide,
    http://www.wowza.com/forums/content....work-interface

    There's a tutorial for MPEG-TS based encoders to help you (if you need it) here,

    Hi Jason,

    I configure my VHost.xml and the error is the same.

    Does exist a way to force publish this stream from a multicast IP to wowza? A Addon maybe?

    This is my cenario:

    IRD (MPEG-TS - multicast 239.20.1.1:5001) --> Wowza (2 IP - one to the internet and other only for multicast - 192.254.1.1) --> Akamai --> Flash players.

    For now, if i plays in VLC (not pushing to Akamai), I will very happy!

    if this really works, I will try transcode this MPEG-TS to H264/ACC.

    What about on the encoder side? Did you put the IP address of the Wowza machine in the UDP url that you are publishing to?

    Is this Windows or Linux? You can use tcpdump on Linux or Wireshark on Windows to see if packets are reaching Wowza from the encoder.

    Instead of the 239.x.x.x address use the IP of the Wowza machine. And if you use port 50001 playback would be udp://127.0.0.1:5001

    Richard,

    Unfortunately, the Cisco's IRD not especify a ip to publish, only a multicast ip. I'm tried to set the wowza's ip, but the same error.

    It's a Linux box (virtual machine) with Wowza 3.1.0 build1410. I have 2 network interfaces: eth0 to access Wowza and eth1 to multicast (with multicast and promiscuos mode). The packets reaching Wowza machine. I'm tried wowza on Windows and is the same error.

    Hi
    This sound like a routing issue to me.

    You can try adding a network route, the command is:
    route add 224.0.0.0 netmask 240.0.0.0 dev eth1

    You may have to use eth0 rather than eth1 but I'm not 100% sure if it will work with eth1.
