Richard,

as I told you there is an IP address issue. I have 5 network interfaces on the server.

IGMP report (join) is performed by 127.0.0.1 which clearly is an issue.

So the key point is to be able to specify the right IP address (192.168.10.11 in my case) to perform the IGMP join.

Thanks for your answer.

Regards

Jérôme

Richard,

please specify because in my VHost.xml file I have 2 HostPort definitions (see above), I changed “*” by “192.168.10.11” and it does not change anything. Indeed these IP addresses are used to bind port 1935 and port 8086.

4

*

1935

…

1

*

8086

…

I also checked the support pages :

https://www.wowza.com/docs/how-to-listen-for-a-multicast-stream-on-a-particular-network-interface

but the result is the same.

Please advise.

Regards

Jérôme

Richard,

All UDP ports are open.

Here is a tcpdump capture of the IGMP messages :

04:34:06.389959 IP 127.0.0.1 > 239.1.1.8: igmp v2 report 239.1.1.8

That means that WMS is using 127.0.0.1 to send IGMP join messages and this is the reason of the error messages. This address has to be modified somewhere in the configuration files.

Can you tell me where ?

Regards

Jérôme

Richard,

I already modified VHost.xml accordingly :

75

true

1024000

65000

true

192.168.10.11

0

50

4096

but this did not solve the issue.

Please advise.

Joe,

the route for multicast is already permanently specified :

239.0.0.0 192.168.10.1 255.0.0.0 UG 0 0 0 eth1

the issue is not the routing, it resides in the way IP IGMP packet is built because it contains 127.0.0.1 as source IP address.

Regards

Jérôme

Hi Richard,

there was an issue with Ubuntu and the network cards we were using so I went to CentOS which is working now.

Now cinematic follows :

source : “mpegts.stream” : 239.1.1.1:5500 (MPEG2TS)
transcoded to “mpegts.stream_720p” (H264/AAC)
issued to “myStream720p” multicast stream

Here is my multicastmap.txt :

mpegts.stream_720p={name:myStream720p,stream:239.100.1.1:5500,isRTPWrapped:false,TTL:63}

Here are the logs :

Everything seems OK but I would like your feedback (especially regarding warnings) and you can see that there are 2 multicast streams generated : 239.100.1.1:5500 and 239.100.1.1:5501 instead of one stream (239.100.1.1:5500).

Thanks for your help.

Jérôme

JEROME_FENEAU · September 9, 2020, 8:58pm

Richard,

regarding the second warning, I understand now why, even if VLC is detecting a stream, there is nothing within 239.100.1.1:5501, I guess the reason is : "audioCodecIdMissing:true "

But why is it happening and how to fix it ?

2nd question : provided that the below issue is fixed, how could I call (under VLC let’s say) 239.100.1.1:5500 to get both video and audio at the same time ? Indeed 239.100.1.1:5500 displays video without sound, I guess solution should not be so far.

Thanks

Jérôme

JEROME_FENEAU · September 9, 2020, 8:58pm

Richard,

you mention : "In the 2nd, it seems that one of the streams in the stream name group has a missing audio codec id. “TranscoderStreamNameGroups#DelayStart.run” indicates that creation of the group is delayed, I guess waiting for the audio codec id. "

Who is supposed to give this audio codec id to Wowza ? Is it generated by Wowza itself ?

Thanks

Jérôme

Richard,

actually audio is not working.
