Hi,

I try to mux audio stream comming from rtsp with a shoutcast stream using AVMuxing mod.

I sucessfully started video merge but cannot combine it with audio. How can i mux video in application named “live” with audio from app called “audio”?

The problem is here:

```auto
IMediaStream localIMediaStream = this.appInstance.getStreams().getStream(this.audioName);

```

It searches for audio stream in itself context, which is not possible.

Maybe fix it this way?

```auto
IApplicationInstance audioInstance = application.getAppInstance("audio");
IMediaStream localIMediaStream = audioInstance .getStreams().getStream(this.audioName);

```

This is of course just a stub.

I cannot use in same app both rtp-live and shoutcast mediacaster. How to avoid that?

Marcin

Hello Marcin

I’d suggest restarting Wowza and running your use-case once more. Then zip up your conf/ and logs/ folders and sending them to support@wowza.com. If you made any changes to the module itself (from the default), please indicate as such upon submission and include the jar file.

Thanks,

Matt
