Is there any method to make alias in one appInstance (or even Application) for stream in another one?

For example: I publish stream myhost/app1/appInst1/stream1 and want to make it available at the path: myhost/app1/appInst2/stream3 or myhost/app2/appInst3/stream1

Standard modules StreamNameAlias or interface IMediaStreamNameAliasProvider2 allow me to change only last part (stream name).

Hi there Alex, and welcome to the Wowza support forum.

I am not exactly sure what you are trying to do, but you may be able to achieve what you described with the MediaCaster system:

[How to use Stream Manager in Wowza Media Server 3](https://www.wowza.com/docs/how-to-use-stream-manager-in-wowza-media-server-3)

You would need to start pulling the MediaCaster stream for each app instance

I hope this is helpful.

You can do something similar by utilizing the [stream name alias](https://www.wowza.com/docs/how-to-get-the-streamnamealias-addon)module. You can create an entry in your aliasmap.stream.txt file. You can also use the IMediaStreamNameAliasProvider2 by resolving to the appropriate url in resolveStreamAlias.

In IMediaStreamNameAliasProvider2 I was suggesting that you can return a rtmp url to resolve in that event handler. Otherwise you can map a stream name to the full rtmp url in stream name alias as well. There is a stream name passed as a parameter but you can resolve it to a complete url.

Thanks,

Matt

Thank you for answer, Salvadore.

It seems that pulling requires to have ready .stream files in content folder. And I want to create aliases to stream when it is published to the Wowza server

Does IMediaStreamNameAliasProvider2 allow to change ApplicationInstance? As I can see from API documentation it only changes stream name.

Currently the only way that I can find is duplicate stream:

[https://www.wowza.com/docs/how-to-duplicate-streams-to-another-application-instance-moduleduplicatestreams](https://www.wowza.com/docs/how-to-duplicate-streams-to-another-application-instance-moduleduplicatestreams)

though it looks like too complicated for my task

Thanks, Matt.

Does this technique works for Apple HLS? I need streams to work on iOS and Android too.
