RTMP and tunneling problem



RTMP and tunneling problem AndrewBarton

macromedia flash flashcom: 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

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!

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)
