Wowza could receive the incoming streaming with the UDP port sharing features, we are using this features.

Is it possible also using the same port sharing fuctionality to relay the streaming from the origin to the wowza edge server?

(this will save a lot of bandwidth, if you want combine one video streaming with different audio streams )

In other words could we implement some plugins to just relay the udp streaming ( only video or only audio streams )

from wowza origin to wowza edge servers?

Thanks,

qstream

Hi,

Salvadore is correct in the traditional method of origin/edge, this is done using WOWZ or RTMP protocol.

However you could try using the PushPublish feature which supports the pushing of streams using MPEG-2 Transport Stream (MPEG-TS).

Please find the article for PushPublishing below if this is something you wish to use.

[https://www.wowza.com/docs/how-to-push-streams-to-cdns-and-other-services-push-publishing](https://www.wowza.com/docs/how-to-push-streams-to-cdns-and-other-services-push-publishing)

For a audio only or video only version of the stream, you can use the transcoder to create a new stream and disable the audio or video.

The name of the streams then coming out of the transcoder must match the stream names in the PushPublishMap.txt file.

You can test the output using VLC player.

```auto
udp://@239.1.1.1:10000

```

Note the @ in the URL which is required with VLC player for playback using UDP.

Regards,

Jason

This would not be supported as Wowza edge servers pull streams from Wowza origin servers, and the protocols used are either wowz or RTMP.

Thanks for you comment, we have used the PushPublish add on,

the problem is you can push a video with a name v1 ( with sdp description ), and two

two audio’s with names a1 and a2 separately, but how to playback it on the edge server with v1/a1 and v1/a2

as combined streams. ( this works if from the encoders send the separate video and audio streams to wowza origin, with

udp port sharing possiblities ).
