Thanks, I'll check out the latest CVS version as soon as I get around to
implementing.
Your experience is very similar to what I was looking for! If it is as fast
as you mention then it will surely be enough to simulate a streaming video,
from the viewer's perspective.
I believe jpg-httpd will be enough for my purposes, however a standard
streaming video would still be nicer. If FlightGear is able to generate
those jpgs, then it may be possible to encode them to a video in real-time,
using third party tools, and stream it. Perhaps I could contribute with such
a feature (not in the near future, I'm afraid).

Yes, the v0.9.10 there a problem with FlightGear Wizard on Windows, but I've
done a fix, please check latest CVS version.
About video streaming, jpg-httpd is working fine and very fast. I've done a
ground station using Borland C++ Builder for a client that is using
Flightgear and this implementation seems to be like your project.
The jpg-httpd option works with impressive performance.

Thanks! That sounds like it could solve my problem. However, I couldn't get
it to work -- FlightGear reports: Unknown option '--jpg_httpd=5502'
My command line, as generated by the wizard, was:
C:\Program Files\FlightGear\bin\win32>fgfs.exe --fg-root="C:\Program
Files\Fligh
tGear\data" --fg-scenery="C:\Program
Files\FlightGear\data\Scenery";"C:\Program

--d
isable-random-objects --disable-ai-models --jpg_httpd=5502
I tried with --jpg-httpd=5502, and I get the same error: Unknown option
'--jpg-httpd=5502'
I'm running v0.9.10, could that be the problem?

Have you looked at the --jpg-httpd option yet?

This works to send jpeg images over the net that can be refreshed fairly
rapidly... Not exactly streaming video, but close. I'm not sure if/how you
could scale it down short of scaling the window on the server machine.
