I change Mediacaster at my /conf/live/Application.xml to
<MediaCaster>
<!-- Properties defined here will override any properties defined in conf/MediaCasters.xml for any MediaCasters loaded by this applications -->
<Properties>
<Property>
<Name>forceInterleaved</Name>
<Value>true</Value>
<Type>Boolean</Type>
</Property>
</Properties>
</MediaCaster>
ad restart WMS.
But WMS still answer just RTP/AVP to DESCRIBE rtsp request and player try RTP/AVP/UDP and only afrter this type of RTSP fail player try to get stream by RTP/AVP/TCP
I use
Wowza Media Server 3 Monthly Edition 3.0.2 build866
