We have an encoder outputting several radio (audio only) streams in a single multicast MPEGTS sharing the IP:port combo.

I’m trying to configure individual radio streams in Wowza from this multicast stream, without sucess, so far.

I’m able to tcpdump the radio streams and then I was able to use Wireshark to extract the MPEG-TS streams and listen to them.

I’m using v4.7 on RHEL 6.8.

I followed these guides, for the specific issues of configuring multicast streams and selecting individual mpeg-ts streams.

I tried to attach the relevant configuration files with no luck.

edit: already was able to upload the config files to the main post.

Hi,

To help anyone in similar situation.

You should create a .stream file under your application name with the following configurations, according to your origin encoder/source:

{  
uri : “udp://0.0.0.0:port\_here”,  
mpegtsVideoIsAligned : “true”,  
mpegtsProgramID : “000”,  
mpegtsAudioPID : “0x111”,  
mpegtsAudioBitrate : “96000”  
}

Check your .stream file under your UI on the “incoming streams” and validate if it’s receiving data.

Then you can use the rtmp or http url on a player to check out if streaming PID is the correct one.
