Cam2x

[flammablepiss]

Could you do it for the ps2 I TOY ?
As it would be camera that many people will have ?

It should be supported using the OV51x driver.

kwl !



(its eyetoy i know)

When I try to use cam2xlib, I am missing "linux/types.h" and "linux/videodev.h" when compiling. Can you tell me where to get them?

They are available in the kernel sources: types.h videodev.h

Thanks,

now there is "just" a linker problem left, it seems to be unable to find the functions in libcam2x.a (see errors below). The lib itself "libcam2x.a" is found (there is a file not found error when renaming the -lcam2x parameter below deliberately to something wrong), just the functions inside seem to be not found. It looks inside "GP2X_Dev\Tools\arm-gp2x-linux\lib", where most of the libs also have counterparts ending with .so and .la etc., maybe that is also needed for libcam2x.a? Besides, I am using the Dev-C++ Tool that comes with the GP2X.

These are the error-messages:

My Logitech QuickCam Chat #3 don't working T_T Is there any way to get it work?

 

[mikapoil]

my logitech quickcam messenger #2 seems to not work

I use the last version of cam2x
I load the driver (z_load_all.gpe)
it goes back to menu
the test does nothing
if I run photocam2x I have this message : "No video device found"

do we need to install a lib (ryleh or else) on the GP2X ?

Someone has the same cam and Succeed to run it ?


ps : sorry for my english <french inside>

Hi,

I crosscompiled a few drivers that should support a lot of webcams, all 2.4 kernel drivers. I remember having problems finding drivers for logitech quickcams. If you get the message "No video device found" it means that the driver did not register your webcam. You could post some output of the dmesg command. If you don't have telnet, launch this script from the menu:
CODE
#!/bin/sh
dmesg > dmesg_output.txt
/usr/gp2x/gp2xmenu &


You should post the contents of the file (first run load_all.gpe then connect your webcam then run that script).

Probably there will be an error message saying that no driver was found that registered the webcam. The easiest way to find a driver for the webcam is connecting it to a linux pc and see what driver it uses for it and then try to crosscompile that driver for the gp2x. If that doesn't work then it is possible that no 2.4 driver exists and you are not able to use it on the gp2x unless you write the driver yourself.

 

[mikapoil]

i am trying :

so i run load_all.gpe then connect your webcam then run that script...
and there ...nothing : black screen
i wait few minutes but nothing new
so i turn off my GP2X

I have a .txt

if you can tell me more about that ...

because I don't know enough about linux to do anything...
i just can search on net to show you :
linux driver for quickcam messenger
and
improved linux driver for quickcam messenger

 

[mikapoil]

finally I buy a eye toy camera (sleh-00031)...
but it's not the end of my problem

i will not explain just see the photo
you will understand



how correct this problem ?

Strange, does the photo seems to "move up" or it is just the bottom part that has to be put on top? You could "fix" this by first copying the bottom part and then put the top part after it, that way you should have a valid picture.

I don't know why this happens, I just recompiled a lot of drivers, only with one driver I made some changes. So that problem has to exist in the drivers itself for linux (in an old version) or is caused by a faulty webcam.

I had the same problem with my Eye Toy, disabeling the code that automatically adapts the picture-brightness directly in cam2x (for which you kindly gave me the source) solved the problem, and the eye toy seems to adjust the brighness automatically to some extent anyway.

I test this cam under windows it work fine
(i use this driver http://eocp.sourceforge.net/inframe.php?lo...p;name=Download)
but on my GP2X the video move up (or down sometimes)
but not all the time
i think jangunhed explain why...

can you send me (or put a link to download) your version please ?
because i'am a noob !

 

[mikapoil]

@Lithosphere :
Could you do a fixed version for eyetoy with the improvement mentionned by JanGunheD ?
....a little update

or permit to JanGunheD to distribuate "his" version...

He can distribute his version. After all he should be able to test it with a camera and already have a working version. If he doesn't give it, I will try to take a look at it.

 

[mikapoil]

we talk about with JanGunheD but he has crashed his HDD
he gave me the 2 files modified
but there is 2 problems
i don't have the sourcecode of your application
and ...i'm not able to recompile

So i ask your help
thanks if you can

i put the 2 files he has changed there
(thinking it's not a problem for JanGunheD)

we talk about with JanGunheD but he has crashed his HDD
he gave me the 2 files modified
but there is 2 problems
i don't have the sourcecode of your application
and ...i'm not able to recompile

So i ask your help
thanks if you can

i put the 2 files he has changed there
(thinking it's not a problem for JanGunheD)

Ok, I have a copy of that code. I recompiled photocam2x with the modified versions of cam2x.c|h. I didn't test it so I don't know if it will work: http://www.sendspace.com/file/ws3lqi .

 

[mikapoil]

tested but not approuved...

the video move again (up or down)
and the video seems to be more ...red

but the problem is really a problem of brightness
because i can have a good video when i don't have much light

Do JanGunheD forget something ?

 

[Lithosphere]

His modifications disabled the brightness correction. So I don't know what is causing this.
