For incoming MediaCaster streams the switch is in the Application.xml /MediaCaster /RTP /RTSP /RTPTransportMode. Change “interleave” (TCP) to “udp”

For outgoing, you can add these Property settings to the Application.xml /RTP /Properties container:

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

```

Make sure all udp ports are open or VLC will fail-over to tcp.

You should not need those Property settings for Android. You just need to allow UDP traffic. That means opening all UDP ports in your firewall (0 - 65335) and properly mapping UDP requests to your Wowza server in your network. Android won’t work otherwise. It is not a Wowza configuration, it is a network and server configuration.

Richard,

i tried [https://www.wowza.com/html/mobile.html](https://www.wowza.com/html/mobile.html) on my android-vlc,it seems that the packets i received still over TCP when my android-vlc behind a NAT!

and i tried this:

forceMPEGTSOut

true

Boolean

rtpWrapMPEGTS

true

Boolean

it still over tcp!

thank you!
