Hi,

I use Wowza media server 3.0 as a VoD (RTSP) server for STBs.

The server streams AAC files using MPEG-TS packets.

I have two questions:

1- How may i force RTSP server output to use UDP instead of RTP?

2- How can i change Packetizer to increase PMT/PAT insertion?

Thanks in advance

I answered your same question [here](http://community.wowza.com/t/-/37849).

You put the properties in the wrong place.

You have:

```auto
<Property>
	<Name>rtpDePacketizerWrapper</Name>
	<Value>com.wowza.wms.rtp.depacketizer.RTPDePacketizerWrapperReChunkMPEGTS</Value>
</Property>
<Property>
	<Name>forceMPEGTSOut</Name>
	<Value>true</Value>
	<Type>Boolean</Type>
</Property>
<Property>
	<Name>rtpWrapMPEGTS</Name>
	<Value>true</Value>
	<Type>Boolean</Type>
</Property>
<!-- Properties defined here will override any properties defined in conf/RTP.xml for any depacketizers loaded by this application -->
<Properties>
</Properties>

```

should be:

```auto
<!-- Properties defined here will override any properties defined in conf/RTP.xml for any depacketizers loaded by this application -->
<Properties>
	<Property>
		<Name>rtpDePacketizerWrapper</Name>
		<Value>com.wowza.wms.rtp.depacketizer.RTPDePacketizerWrapperReChunkMPEGTS</Value>
	</Property>
	<Property>
		<Name>forceMPEGTSOut</Name>
		<Value>true</Value>
		<Type>Boolean</Type>
	</Property>
	<Property>
		<Name>rtpWrapMPEGTS</Name>
		<Value>true</Value>
		<Type>Boolean</Type>
	</Property>
</Properties>

```

the MediaCaster Property “forceInterleaved” only affects incoming streams.

Try adding these Property settings to the /conf/[app-name]/Application.xml /RTP /Properties list:

```auto
<Property>
<Name>forceMPEGTSOut</Name>
<Value>true</Value>
<Type>Boolean</Type>
</Property>
<Property>
<Name>rtpWrapMPEGTS</Name>
<Value>true</Value>
<Type>Boolean</Type>
</Property>

Thank you for your answer. But it dosen’t work for the two questions.

For point 1, i have follow steps described in [https://www.wowza.com/docs/how-to-re-stream-video-from-an-ip-camera-rtsp-rtp-re-streaming#config](https://www.wowza.com/docs/how-to-re-stream-video-from-an-ip-camera-rtsp-rtp-re-streaming#config).

I have added next XML tags to “conf/vod/Application.xml” file.

* * *

forceInterleaved

true

Boolean

* * *

But the server is still sending RTP packet instead of UDP packets.

For point 2 , steps in [https://www.wowza.com/docs/how-to-control-video-and-audio-pid-and-streamids-for-outgoing-mpeg-ts](https://www.wowza.com/docs/how-to-control-video-and-audio-pid-and-streamids-for-outgoing-mpeg-ts) describe Pid and Stream id changing , whereas what i need is the frequency of PAT and PMT insertion.

Best regards

I have added these properties but server is still sending RTP instead of UDP.

Below conf/vod/Application.xml.

Could you tell me what is wrong(server version is 3.0.3).

Thank you in advance.
