    Default RTSP TCP Only

    Hello!

    Is it posiable to configure Wowza Media Server to answer to DESCRIBE request from RTSP client with RTP/AVP/TCP capatibilities only? not a RTP/AVP?

    This will instruct RTSP client to use TCP (RTSP interleaved mode) from the start, to avoid initial UDP fail if RTSP client is behind NAT.

    You can force RTSP/TCP by adding the forceInterleaved Property to /conf/[app-name]/Application.xml /MediaCaster /Properties.

    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

    Actually, forceInterleaved doesn't affect playback of RTSP. It is for re-streaming from a MediaCaster source over TCP instead of UDP

    If WMS with forceInterleaved will answer to RTSP DESCRIBE request with RTP/AVP/TCP - this will be real 'FORCE', because this option tell
    to RTSP playback to use TCP.

    As I know RTP/AVP - inform RTSP playback that UDP and TCP can be uses as a transport. And UDP is a preffer.
