Is there any way to configure a wowza application to packetize only specific streams?
In the Application.xml I have added the _cupertinostreamingpacketizer_ to the _LiveStreamPacketizers_ tag, but this way all streams are packetized and I get the error:
```auto
2014-08-12 16:31:58 comment server WARN 200 CupertinoPacketHandler.handleHolder[**stream name**]: Invalid audio codec for iPhone/iPod:SPEEX - - - - - -
```
I have tried the MediaStreamMap.removeLiveStreamPacketizer to remove the packetizer from the streams, but it continues to packetize the streams.
Configuration settings Code Snippets are welcome as well.
Thank you in advance!

Hi,
Did you try implementing the “PacketizerControl” module described in the [How to control which streams get packetized for HTTP streaming](https://www.wowza.com/docs/how-to-control-which-streams-get-packetized-for-http-streaming-modulepacketizercontrol%28ModulePacketizerControl%29) forum article?

This post has helped: [https://www.wowza.com/forums/showthread.php?16838-Limiting-the-Cupertino-Streaming-Packetizer-to-a-selected-set-of-streams&highlight=setLiveStreamPacketizerList](https://www.wowza.com/forums/showthread.php?16838-Limiting-the-Cupertino-Streaming-Packetizer-to-a-selected-set-of-streams&highlight=setLiveStreamPacketizerList)
I was missing the IMediaStream.setLiveStreamPacketizer and IMediaStream.setLiveStreamPacketizerList methods.
