i can't find .linuxtrack file

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Build the current sources from SVN. Start the application, trying to save 
preferences and when I start again ltr_gui preferences seems not to been saved

What is the expected output? What do you see instead?
I can't find the file ~/.linuxtrack

What version of the product are you using? On what operating system?
Latest SVN sources on Ubuntu 13.04.

Please provide any additional information below.
Ltr_gui works perfect i can see the 3D Model working awesome. But when i try to 
run it with FlightGear it doesn't work. It seems to me that this is because 
preferences are not ok.

Thanks a lot for your work!

Hello,
the preferences are supposed to be in ~/.config/linuxtrack/linuxtrack1.conf 
file.
From the log, it seems that there are changes in the default config, and it 
seems to be read allright. I'd recommend you to set other than JPEG format 
(RGB3 or BGR3 should be OK). Also the webcam doesn't seem to report any usable 
framerates at all (and my code seems to use uninitialized values, which is a 
bug that I'm going to take a look at).

And if I'm correct, the problem you have is that webcam setup is not 
remembered, right? I think I know where the problem is - the name reported by 
webcam starts with a space, that is stripped when the prefs are read in and 
then it wouldn't match...
I'll take a look at it too, hopefully today or tomorrow I should be able to 
commit the fix...

In the meantime, if you have access any other webcam, try it instead...
Thank you for giving it a shot and for reporting the problem.
Kind regards,

Michal

Hello Michal,

I've tried the software right now with another webcam and it works awesome on 
FlightGear. I've still to configure it better, but now i can't do it because i 
am so excited to fly on 3d enviorment! ;)

I send you the 2 preferences files that ltr_gui creates for the New Webcam (the 
one that is working) and the Old Webcam (the one that it is still not working). 
Any more files you need just tell me and i'll send you as soon as possible.

I've set the option Pixel-format = YU12 in both webcams and i can see the 3D 
Model working great.

I've also like to know if there is a way to reconfigure the webcam settings at 
the sametime that FlightGear is running. And also if is there any command to 
disable it for a while and enable it agein? (Maybe if i need to go to the 
toilette i would like to not get my view crazy!)

Thanks a lot for your work!

Hello Oriol,
I'm glad that you made it work at last... 

As for flightgear bindings, they are a work of Alexander, but I might be able 
to help a bit... I assume you are using the ltr_pipe to get the data to the 
sim. There is a possibility to send it (ltr_pipe) signals for recenter (HUP) 
and pause/unpause(SIG1) - see README.ltr_pipe in share/doc/linuxtrack. However 
I don't think it is very convenient.

I'm going to take a look at the Flightgear bindings soon, to make them more 
user friendly; in the meantime, you can still use the ltr_gui to control the 
tracking - just start ltr_gui (and start tracking), then start ltr_pipe and 
flightgear. Then you can control the tracking from ltr_gui. And to save a bit 
of CPU, you can disable the 3D preview in the fourth pane and enable it only 
when you need it for setting things up.
Kind regards,

Michal

I just committed a fix for the bug you encountered. Could you try to compile 
it, run it using the previous webcam and let me know if it works?
Kind regards,

Michal

Hello Oriol,
I'm glad it works for you and thank you for the report!
If all goes well, a new linuxtrack universal package should appear in about a 
week (provided I don't encounter any major problems), so you won't have to 
compile it...

I'm going to close the issue; should the problem reappear, feel free to reopen 
it or open a new one...

Kind regards,

Michal
