Hi,
For RTMP playback, you can set a stream to video only using onStreamCreate event below:
[How to use event listeners in Wowza#IMediaStreamActionNotify3](https://www.wowza.com/docs/how-to-use-event-listeners-in-wowza-media-server#IMediaStreamActionNotify3)
something like this.
```auto
public void onStreamCreate(IMediaStream stream)
{
stream.setReceiveAudio(false);
}
```
Another option would be to use the [Transcoder AddOn](https://www.wowza.com/docs/how-to-set-up-and-run-wowza-transcoder-for-live-streaming) and create an encode which does not have audio by editing the transcoding template.
The encode could have the Video/Codec as PassThru and the Audio/Codec as Disable as shown in the example below.
```auto
truesourcemp4:${SourceStreamName}_source
```
Regards,
Jason

Hi,
> When testing in the Player to stream " 999\_portalpet\_512 " does not work and the " 999\_portalpet " works with audio .
What does not work exactly? It doesn’t play at all? What do you see? Any messages?
What are the source stream’s video and audio codecs ?
