I can agree completely with Graeme about this point. We're running
multiple FCS server on SUSE Linux and it's performing beautifully...

Really, that is very interesting Graeme, certainly worth a try,
thanks!

Trust me.. Try linux. It's completely different when it comes
to tunneling. I've bought the tickets, taken the pictures, got
the shirt AND tatoo when it comes to messing with tunneling.
To test, the dev version is fine and free since you'll have to
buy the linux license when (notice I didn't say if) you switch over.

Guys, thanks for you thoughts...
Brian - I agree, the numbers many not technically be wrong.
But, they are, at a minimum somewhat misleading, you have to
give me that.
Mike - I agree (and I think everyone on this list should know)
that their content is going to be blocked by a LOT of
organizations. I now suspect that Flash is NOT the most
universally available player for streaming media for this
reason specifically. In my mind, that title is returning to
Microsoft Windows Media.
Of course, there are still some great features to Flash and
FCS. And, we are now re-working our strategy for delivering
services/content. We going to allow people to create/produce
content using a Flash/FCS application. But, we are going to
deliver content using Flash V7 and FLVs served off of
web-servers. This is a great solution. The content is not
blocked. And, most corporate users, it seems, even though they
are behind a corporate firewall, have or can get the latest
version of Flash. Of course, this also means that we cannot
and will not use Flash for live presentations and/or any of its
other neat interactive features, like chat.
Graeme - I am using FCS 1.5 on a Win2000 server. But, I don't
see why/how that would matter relative to ports being
used/blocked on the client side of the equation. Can you
expand on that? Maybe there is an opportunity to connect I am
missing.
I think it is interesting that no one could speak to whether
Breese uses RTMP.
Cheers!

FCS' Value/Accessiblity
Troy,
Your definitely not alone. Our group is having a hell of a
time getting FCS video through to our corporate clients because
they are mostly behind strict Firewalls or on very slow dial-up
connections (3rd world countries!!). Seems like RTMP and RTMPT
are both being blocked. Even when we have a client get
through with HTTP tunneling, it's extremely slow, even on LAN
connections. We opened up every available port including 7070
and the Real media port.
We had our clients go through some testing which included the
Port Tester (peldi.com) and a couple different versions of our
FLV's. We were able to determine that about 10-15% of our
students can not receive the video when it is streamed from FCS
using either RTMP or RTMPT, all ports fail and no movie loads.
About 20% receive very poor quality streaming video, even when
viewing low-bandwidth versions (buffers every 10-15 seconds),
most of the time they connect using HTTP tunneling.
As a work around, we have had to offer non-streaming video
using WMV's in conjunction with streaming FLV's to satisfy 100%
of our clients. At this point, our organization is not sure
why we use streaming FLV's, it was suppose to go through
Firewalls and eliminate these issues because it uses the Flash
plug-in. Our original goal was to reduce the needed
plug-ins to a single one, Flash. Good question about Breeze, I would
assume, since it's built on FCS technology that the same issues
would occur for streaming video. Don't expect Macromedia to be
forthcoming on this issue, though they do admit they have
trouble with Firewalls, there is no mention of this much trouble.
Thanks,
Mike

Value/Accessiblity
Anyone have any perspective on RTMP penetration rates?
Below is a quote from the MM site. I believe it is WRONG. In
fact, my personal research (people calling me and telling my
apps don't work), suggests that somewhere in the 10-20% of all
computers are behind firewalls that block RTMP, even if it is
tunneled through http. And, to be clear, I have bent over
backwards to ensure that my apps and my server at open to
connecting over any of the ports and protocols available.
Am I alone in this finding? Am I missing something? I doubt
it. I hope I am wrong. Does Breeze also use RTMP?
Any thoughts would be great...
Thanks, Troy

FROM MACROMEDIA'S SITE:
"By default, the Macromedia Flash Player communicates with the
Flash Communication Server using RTMP protocol over port 1935.
If that fails, it will try again over ports 443 and 80 in an
attempt to workaround firewall settings within a company, which
prevents TCP/IP connections over non-standard ports. The above
approach allows approximately 96% of all users to access
publicly accessible Flash Communication servers.
To support closer to 100% of the users we need the Macromedia
Flash Player to negotiate connection to the external Flash
Communication server though a proxy server (if there is one),
or use HTTP protocol to transmit RTMP packets (HTTP tunneling)
if there is a firewall (which allows only HTTP content to be
sent out to public servers).
