Re: [Flightgear-devel] Flightgear visualization as streaming video
Hi Adam, In fact, the 0.9.10 is very slow, but I did a rewrite of httpd-jpg code and I believe that this feature will be released with 0.9.11 version. Try get latest CVS code and you'll see that is really very fast. FlightGear now is capable to stream the images almost so fast as simulator screen.

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.

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.

For capturing FlightGear video, I've had my best results using a scan converter to convert the vga signal to NTSC (or PAL) then feeding that into a video capture device attached to a second computer. Tools like xvidcap and fraps compete with FlightGear on the same machine for cpu cycles and can bring down your frame rates.
