Hello,

is there any way to connect stream files to Source Specific Multicast Streams?

I have some streams over an cisco switch which is doing SSM so I have to enter the source address of the stream.

E.g. in VLC: udp://10.69.xx.xx@239.4.xx.xx:8208.

best regards

Manfred

Hello,

Thanks for contacting Wowza Forums!

You can setup .stream files with the particular multicast stream info and Wowza should pull that stream into the server:

.stream file setup

Hello Jermaine,

I know how to setup .stream files.

What I like to do is connecting an MPEG-TS based encoder over an cisco switch which is doing IGMP-V3/SSM to the Wowza Streaming Engine!

What I tried till now is enter the multicast address:port in the Add Stream File dialog box and enter the “multicastInterfaceAddress\_in” in the “Incoming RTP Datagram” section in the _vhost_ configuration.xml file!

Neither the Interface address of the Wowza Streaming Engine nor the actual source address is working!

The only way to get SSM working is to use a different Streaming Software which is capable to do Source Specific Multiacast.

regards

Manfred
