Question

RTMP and tunneling problem

Hi,

We have some Flash 8 streamed video encoded at around 380kbps designed for viewers on 512kbps connections.
If the connection is made using RTMP on port 1935, everything is fine but if the viewer is behind a firewall and the connection drops down to RTMPT on port 80 they see continual video pauses with buffering messages. I can reproduce this by disabling port 1935 on my router. I think there are two possible reasons for this problem:

1) the number of bytes added to the stream by HTTP tunnelling over port 80 is very large,

2) because HTTP is a non-persistent protocol, there is significant time added for packets to be transferred.

I'm guessing it is probably the later which is the culprit so my question is, how do I calculate an encoding bit rate to ensure correct streaming over the tunneling protocol?

Thanks,

Andrew

    Hello, i am new in the FMS world, i have configured a FMS3.5 in a windows 2003 server and all work fine.
    I could make a http conexion for On demand (VOD) but i Could not for Live contents . I change the configuration of web server´s config file called httpd.conf and VOD works fine but i dont find documentation about Live contents and how i have to config this file to make live contents over http.
    Maybe it is imposible. I am waiting for your answer.

    Thanks for your time.

    I have the exact same problem. RTMP works fine, HTTP drops transfer rate down to around a third causing constant buffering. Is there any solution to this?

    All our problems went away when we moved to another streaming server.
    All I can say is Limelight Networks just works...
    (I also set the 'buffering' value to 2 seconds, up from its default of 0.1 seconds)

    Hi,

    I've got a similar problem... We have developed a game with FMS and it was working just fine. Then one of our computer started having problems with FMS and other programs so we formatted the harddrive. Afterwards, we reinstalled everything and here it was! The FMS was acting weird, not recognizing our SharedObjects and some NetConnections ... We tried using the rtmpt and port 80, and it's working only on one computer... Nobody can connect on the FMS, even with all firewalls desactivated. When we set the configuration back to rtmp and 1935, others can connect but we have the same old problems with SharedObjects and stuff...

    What can be the source of this?

    The problem just magically solved itself. After having some problems with persistant SharedObjects, we discovered that the SO-files were missing on the server. Turns out the FMS lacked write permission on the applications folder and it's sub folders. When this was corrected, suddenly a folder named http showed up in the applications folder. With pounding heart I tried connecting through RTMPT and... It worked like a charm.

    Write permission, write permission, write permission. That's the key!
