WebCam - SPCA50x drivers

Hi everyone,
I have recently managed to compile the SPCA50x driver (http://mxhaard.free.fr/download.html) for Asus. The driver claims my camera (Mustek Gsmart Mini2), however when I try to grab a picture using a userland app like videodog (http://planeta.terra.com.br/informat.../videodog.html ) or palantir (http://www.fastpath.it/products/palantir/) Asus reboots :(

I'm just wondering if maybe someone has also experimented with this driver and made it work... The firmware I'm using is 1.9.2.7-3c (Asus 500gx).

Thanks
LP

Ps

Here is the driver (which I believe is broken, but have tested it only with that Gsmart Mini so far), and here is the app that should grab images.

Code:

insmod spca50x.o ./videodog -x 320 -y 240 -w 3 -d /dev/v4l/video0 -f test.jpg

Could you please try it with your camera? The list of supported cameras is here.

Working!

OK, the problem was in some magic MIPS-specific compiler options. Now the driver is working! :D

It's working fine with palantir

and also with manually launched rcamd. How do I "integrate" this driver to Asus and make the "USB Application - Web Camera" work with it?

Well, integration means changing web pages, probably httpd variables and modifying rc...
Does it work out of box or you've modifed sources somehow?
I would like to integrate this to the firmware, but I'm busy at the moment. In fact kernel module should be integrated to the kernel sources and should not be separate part.
Could you please make kernel patch?

this module is developed specificaly to be out of kernel (to avoid pwc mistake??) :o

Out of the box. Makefile was the only thing that needed some edits.

I'm afraid my little Linux experience does not permit (I am just a hobbyist when it comes to Linux/GNU stuff). Sorry :(

yes, but adding it to our kernel sources simplifies firmware compiling.

Image Size

If you integrate it to the firmware, could you please add one new image size option to the web page? My camera happens to support 176x144 instead of 160x120...

If there's anything I could do to help, please let me know (but it has to be something more beginner-like than patching the kernel ;) )

Thank You!

I've tried this version of compiled spca50x with my Genius VideoCAM Express V2 (USB ids (0x0458, 0x7004)) with no success (yet?) I got router reboot (or hang) while trying to capture image using mvc application. I have not tried videdog since I got an expression that mvc is using v4l interface for capture, so it should be working. I've also tried to get some debug out of spca50x.o adding debug switch to insmod line with no success - may be debug is not compiled?

I'll try videodog with spca50x.o this weekend and let you know if it helps. It would be really nice to use spca50x.o on asus, so if I can help by trying it wiith my cam - I am ready, let me know

And thank you for your efforts

regards

Debug messages are not compiled to make the module smaller - sorry, I should have mentioned that. Try the "debug" version of the module, which has debug messages included:

Hi

Thank you for the module compilation :D.
I have also the Genius V2 cam, can you tell me which version of the driver did you compiled ? The last time i tryed it, this cam wasn´t supported as far is needet for all-day operation since it didn´t adjusted the shutter speed for propper brightness controll which is needet for the way the cam works, with no dram and direkt video aray to usb transfers. This makes the framerate heavily light-dependant :mad:.

I am trying it just the moment.

As i suspekted, the picture is unusable, i can hardly recognise anything, spurios pixels and a greyish picuture at all.

Also, Palantir crashes after a short time of operation.

Code:

This is a fault of the cam support of the driver, not depending on your nice work. I think other better supported cams should work fine with this driver and he should be integrated into the main modified firmware line.

Seems to be a memory leak problem or similar, cause it kills various processes as well.

Well, I've Genius V2 also, and yes it's pretty useless at this time. Also, driver is looking terrible for me...

Inside of driver, no idea.
I just wonder why the hell we all habe this crapy cam, i bought mine with the router for 15eur reduced price, and now it sits here and collects dust :)

Nevetheless, including the driver would be nice for all which have cams which support this driver, maybe not in the web gui ...

Well, in fact I've also Creative WebCam NX, which is supported by zc030x driver and most likely I will include this driver as soon as it would be finally cleared and bugs inside it fixed. This driver is looking pretty good to me.

Hello,

So it looks like spca50x is completely useless with Videocam Express V2... Pity :(, I had an idea to finally find usage for this cam.
