client-server media relay using RTMFP in FMS 4

Hi,

I am trying to make clients to connect FMS4 server over RTMFP for my video conferencing application.

It is basically a client-server media relay application in which clients with webcam/mic connect the server and the server relays video/audio data to other clients. This application is working perfectly with FMS 3.0 but it was RTMP rather than RTMFP - I simply replaced 'RTMP' with 'RTMFP' in netConnetion and tried to test in Flash Media Development Server 4.0, but it is failed to make a connection from a client - it was working after replacing it back with 'RTMP' of course.

I believe server-client media relay is possibe using RTMFP in FMS4 because Adobe said:

"Although RTMFP is often used for peer-assisted networking applications, you can use RTMFP in unicast, broadcast, and multi-point publishing applications as well. Simply replace the RTMP protocol in the NetConnection.connect() call with the RTMFP protocol:" in

http://help.adobe.com/en_US/flashmediaserver/devguide/WSa4cb07693d123884520b86f312a354ba36d-7fff.html

Do you think RTMFP is only for peer-to-peer/multicasting application rather than traditional applications using client-server relay?

Please give any advices.

Thanks!

Michael

    Hi Michael,

    Oh...  those IPs are fake ones. I modified them for security. BTW, Is it right position in the Adaptor.xml?

    Thanks,


    after re-reading the comments in Adaptor.xml for ...HostPort, you need to say something like

       ...

       <HostPort public="68.64.123.123:19350-65535">:19350-65535</HostPort>

       ...

    I've been able to do RTMFP unicast without any problem.

    Firewall issue perhaps? According to the docs, unless you've reconfigured the RTMFP port range FMS will redirect the connection to a port in the 19350-65535 range.

    and remember, RTMFP uses UDP.  by default, ports 1935 and 19350-65535.

    and if your FMS is behind a NAT, you will need to manually configure information about the translation in .../fms/conf/_defaultRoot_/Adaptor.xml in the Adaptor.RTMFP.Core.HostPortList area.

    Thanks for your reply, Michael.

    As you suggested I modified the file:

    <!--                                                                     -->
            <!-- If a core listens on host1:1005, its publicly advertised address    -->
            <!-- will be host2:4005.                                                 -->
            <!--                                                                     -->
            <HostPort>68.64.123.123:19350-65535</HostPort>
          </HostPortList>
        </Core>
      </RTMFP>
    </Adaptor>

    I added the server's public IP before colon and restart FMS, but no luck.

    Before doing this, I got "172.40.100.12:19351" in NetLimiter which can capture my network traffic to the FMS server.

    172.40.100.12 is the private IP Address that I got when I did ipconfig on the FMS server.

    Please help...
