Hi.
Like in the subject - is it possible to specify number of viewers and after reaching this number make Wowza 4 switch to other CDN?
Is there any instruction how to do it?
Thank you.
Sebastian

Hi,
This is possible, but would require some development. You would use the [Push Publishing API and sample code](https://www.wowza.com/docs/how-to-push-streams-to-cdns-and-other-services-push-publishing#api) to begin with.

Sebastian,
There is not a built-in, configurable way to do that. You use [this example](https://www.wowza.com/docs/how-to-limit-the-number-of-viewers-to-a-stream-modulelimitstreamviewers%28ModuleLimitStreamViewers%29) as a starting place (the source code is in the collection download), and instead of limiting playback, switch to the other CDN using the PushPublish API. There are more push api examples in [install-dir]/documentation/serverapi PushPublishRTMP

Thank you.
Link in your post - I can not find information how to do it ? Can you give more details ?
I try imagine what for Wowza has functionality “push streams to other CDN” ?
