ad restart WMS.
<!-- Properties defined here will override any properties defined in conf/MediaCasters.xml for any MediaCasters loaded by this applications -->
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
