How to Using Multicast vie RTSP using PushPublish modular

[Jarry_Huang]

Hi.

I configured pushpublish modular to restream a wowza stream to other CDN systems.

I’ve successed configuring a MPEGTS vie udp multicast stream, using this setting in PushPublishMap.txt:

100.stream={profile:“mpegts”, streamName:“100.stream”, host:“239.1.1.11”, port:10000, rtpWrap:false}

And I can play in VLC using udp://@239.1.1.11:10000 . It is a multicast stream.

I’ve failed to configure a native RTSP stream using multicast stream.

Setting in PushPublishMap.txt is:

100.stream={profile:“rtp”, streamName:“myStreamRTP”, host:“239.1.1.12”, videoPort:10002, audioPort:10004}.

The 100.steam is correct and can be played using this address:rtsp://IP:1935/dvr/definst/100.stream .

There is a SDP file generated in forlder applications\dvr\sdp named 100.stream_destination.sdp. And VLC can play this SDP file.

But VLC cannot play any address like this:

rtsp://IP:1935/dvr/definst/myStreamRTP

How can I play a rtsp stream using multicast?

Best regards.

Hi,

Can you try playing back the stream using this URL?

rtsp://IP:1935/dvr/_definst_/myStreamRTP?multicastplay

Hi Zoran:

Thank you for your reply.

I’ve tried to playback this url using VLC, I received this error.

Your input can't be opened:
VLC is unable to open the MRL 'rtsp://192.166.62.116:1935/dvr/_definst_/myStreamRTP?multicastplay'. Check the log for details.

And the log in wowza is :

INFO rtsp connect 25278661 -
INFO stream create - -
INFO stream unpublish - -
INFO stream destroy - -
INFO rtsp disconnect 25278661 -
