The specs available with me are as follows,

**Encoder** Niagara GoStream Pro

**Streaming Server** Wowza Media Server 3.6.4

I want to be able to stream the content from the Niagara encoder to clients using RTMP protocol.

I could do unicast with Wowza successfully using Niagara encoder, with the settings.

Check out our [mpegts article](https://www.wowza.com/docs/how-to-publish-and-play-a-live-stream-mpeg-ts-based-encoder) as that should get you started. Within that article, it specifies how to orient your [playback](https://www.wowza.com/docs/how-to-publish-and-play-a-live-stream-mpeg-ts-based-encoder#playback) for rtmp.

Hi,

You cannot push a multicast stream out of Wowza using the RTMP protocol.

Wowza will be able to provide multicast output using MPEG-TS/RTP/UDP protocol.

In order to be able to provid ethe multicast output from Wowza, you will need to use the [PushPublishing Addon](https://www.wowza.com/docs/how-to-push-streams-to-cdns-and-other-services-push-publishing%28push-to-CDNs-and-other-services%29)

Also, another aspect that you will need to be aware when using multicast is that you won’t be able to push that stream across internet. You could only do it in your private network.

Isn’t this useful when the encoder-\>wowza server part is multicast? I want wowza server → client part to be multicast.

Will your article about mpegts do the trick for me?
