[Flightgear-devel] Flightgear visualization as streaming video
Hi, I would like to use FlightGear to generate the scene observed by a UAV's onboard camera. Basically, this would translate to feeding FlightGear the FDM data and visualizing the image generated by FlightGear in another computer, across a network, using for example streaming video. I suppose this is a bit of a far-fetched idea, but is there any sort of support for this (or something similar) already implemented? If not, do you have any suggestions on how to achieve it, using external tools and/or contributing to FlightGear? At the moment I'm just brainstorming!

Re: [Flightgear-devel] Flightgear visualization as streaming video
Hi Curt, Yes, I had already seen your videos, pretty impressive! -- and a fantastic demonstrator for FlightGear :) My issue, however, is not quite that: I wanted to capture the FG imagery and stream it over the web...

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 Files\FlightGear\scenery" --airport-id=02Q --aircraft=f16 --control=joystick --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?

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.

Re: [Flightgear-devel] Flightgear visualization as streaming video
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). Antonio _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Leidson Campos A.

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. Leidson Campos PlanetaMessenger.org Java Universal Messenger On 5/23/07, Antonio Almeida <[EMAIL PROTECTED]> wrote: Thanks!

[Flightgear-devel] Addressing the discontinuity that occurs when using discrete terrain altitude data during landing...
Hi! I've been working on a prototype flight simulator and I'm running into an issue I have no idea how to solve, so I decided to ask here since this very same problem might have been addressed in FlightGear. I want to model the landing of my aircraft. My problem lies in the altitude data. The data I have to use is a pixel map, which means that one "square" (which has around 100 meters side) has a certain value of altitude and the adjacent "square" has a completely different value... This means that if I try to land the aircraft in the border between two squares... it will either fall down or crash against this "virtual discontinuity"! I'm betting there's an obvious solution to this, but I'm out of ideas!... Any suggestions? Thanks!

[Flightgear-devel] Problem using external FDM
Hello all, I'm trying to get my FDM to work with FlightGear. My FDM runs in Linux and sends packets to FlightGear using UDP. Everything works fine when FlightGear runs in Windows on another machine in my network. What I cannot do is get things to work when FlightGear is running under Linux and on the same machine as the FDM. What happens is that my FDM correctly sends the packets to the loopback interface and specified port, as reported by a packet sniffer, but FlightGear does not react. Possibly relevant information follows: Linux: SUSE 9.3 FlightGear version: 0.9.3-91 Ports tried: 5500, 12204, 7789 Example FlightGear parameters: fgfs --native=socket,in,30,,7789,udp --fdm=external (also tried --native-fdm instead of --native) Relevant FlightGear console output: Parse I/O channel request: native,socket,in,30,,7789,udp protocol = native medium = socket direction = in hertz = 30 hostname = port = 7789 style = udp Thanks, Antonio Almeida DISCLAIMER: This message may contain confidential information or privileged material and is intended only for the individual(s) named.
