webcam install

Trying to install Micro Webcam IC150C.
Continusously get the error message:
Could not connnect to video device /dev/video0.
Please check connection.

/dev/video0 exists.
Any ideas on solving this problem.

What are the file permissions on /dev/video0?

Post the output of ls -l /dev/video0

d1l2w3

08-13-2004 09:05 AM

permissions for /dev/video0 are 'don:video"
ls -l /dev/video gives the following:
crw------- 1 don video 81, 0 Aug 13 06:28 /dev/video0

This is what happens when I try to use 'xawtv'.
This is xawtv-3.91, running on Linux/i686 (2.6.3-7mdk)
can't open /dev/v4l/video0: No such file or directory
v4l-conf had some trouble, trying to continue anyway
v4l2: open /dev/v4l/video0: No such file or directory
v4l2: open /dev/v4l/video0: No such file or directory
v4l: open /dev/v4l/video0: No such file or directory
no video grabber device available

Are the two related.
How do I find out if v4l exists?

Here is my set-up

Code:

mark@~/$ ls -l /dev/video0

crw-rw-rw-    1 root    sys      81,  0 Mar 10  2003 /dev/video0

so try (as root) chmod 766 /dev/video0 to give read and write permissions to others and world but I don't think that is the problem,

I'm not really up on this stuff, esp Mandrake, is user don a member of the group video?

As for the v4l part I really can't say, when I installed xawtv (version 3.93 BTW) I only had to change permissions on /dev/video0 to give rw to others since it belonged to root and it worked, that's why I suggested looking at the permissions first.

To find out if v4l exists do locate v4l
Maybe the manual pages on v4l will give you some ideas?

Sorry I can't help more,

NEWSFLASH I just tried my camera out and it doesn't work any more :scratch: :cry: hopefully somebody who knows what they are doing will chime in lol :o

This is leaving me :scratch:

After a bit of googling if I run xawtv -noxv my webcam (creative webcam3 works fine)
so I think I am going to have to hit the man pages and google more, sorry I couldn't help you more,

Webcam problem

Has anyone been able to get a Micro IC150C working with MDK 10?
I keep getting a cannot connect to '/dev/video0' error.
'/dev/video0' is there. I have permission.
'sane-find-scanner' shows it as a 0x0461 0x0815 libusb:002:003

Any ideas on how to solve this.

I might be of SOME help, but you won't get anywhere looking for that.... Assuming you are running X-desktop...If you go to hardware browser... that maybe the model number... but who is the chipset manufactured by? It definitely is NOT Micro Innovations. I got almost the same webcam and trying to find the same thing. I'll keep posting and see what I can find.

wytiger

08-20-2004 05:19 PM

I have the same thing! So I'll share what I have so far...

The spca50x driver supposedly works with it (http://spca50x.sourceforge.net), and more importantly, if you are running a 2.6.x kernel, use the driver here:
http://mxhaard.free.fr/download.html

I can compile the driver on my FC2 box, and it is recognized as an IC200C (not an IC150C, but I imagine that may not be an issue), but the screen only shows black using gspy, gqcam, etc.

Maybe you can have better luck with a different OS? Please let me know.

wytiger

08-24-2004 06:18 PM

You need the spca50x drivers, located here: http://mxhaard.free.fr/download.html

hi, i was trying to install the spca driver.
I've done the "make", and "make install" commands.

Quote:

If you have made install, do as root: modprobe spca50x

When I tried, i get the error message:

modprobe: command not found

Where is the modprobe command???

I'm using Fedora Core 2, and a Genius Videocam Express v2 camera
The camera is on the list of supported cameras (in the spca readme file)
How to install the v4l driver? I have gnome-meeting with v4l plugin installed

Sorry about the delay. Went on vacation.
Downloaded 'spca' as suggested.
These are the instructions on how to install.

Kernel 2.4.x
configure your kernel
make dep
go to the spca5xx directories
make clean (to be sure)
make
if all goes right as root :
make install

Here is what happens when attemping to install.

[root@localhost /]# make dep
make: *** No rule to make target `dep'. Stop.

Tried as 'user' and 'root.'

How do I solve this?

SUCCESS! Well, almost...

Even though the IC150 and IC200 share vendor and product IDs, they are different chipsets. I will have more info tomorrow since I did the work at the office, but changing the source to use the spca561 bridge worked for me.

Michel Xhaard has some info here, showing that the IC150 is in test, so I made some changes to the source to reflect this (latest release 10092004), and I am now able to see video through my IC150 using spcaview.

wytiger

09-13-2004 11:31 PM

For those that may be watching this thread instead of this one, I have had some success with the IC150. Since I did the work at the office, I will post my findings tomorrow for you.

wytiger

09-14-2004 06:24 PM

My previous post's patch missed a pair of line changes. Here is the repost. Apologies for any confusion if you read the previous...

This patch will work for the spca5xx-10092004 release. It has been tested successful for me on FC2, but YMMV.

Please note that this patch will replace some lines meant for the IC200, so do not use if you have an IC200 as well as an IC150. It's not perfect, it's not pretty, but it does appear to work!

Do you have the kernel source installed? That message makes me think not if the directory does not exist...

Also, as far as the patch is concerned, I suspect that your created file may be word-wrapped which could explain errors with the lines not syncing.... just a SWAG, though.

wytiger, it worked

I got IC100 webcam and was just trying my hand with spca drivers. Initially it did not work though everything installed smoothly, the patch, the drivers everything was smooth. But it did not work. I thought that the chipset of IC100 would be different and that's why its not working.

Then I went to /lib/modules/2.6.x/drivers/usb/media and saw that the spca driver had permissions 600. I then changed it to 711, rmmod'ed the spca driver and again insmod'ed it and this time it worked.

My Micro IC100 webcam works. But the picture is not at all SHARP and there's no way i can increase the sharpness in spcagui. And one more thing, gnomemeeting is able to detect the webcam but is unable to open it. By "open it", i mean it shows nothing. Any pointers to this.

I got FC2 with the kernel source present.

regards,
vijay.

Patch e-mailed to you. Also, run the following command, and list the results to the forum:

Code:

You should be looking for something that looks like kernel-source...
If you do not see it, try and run this as root:

Code:

urpmi kernel-source

(Please bear in mind that I am not a Mandrake user, and therefore cannot attest to the accuracy of the above command)

rvijay17:
Does Gnomemeeting show a black window where the video feed should be, or does it not register that there is a camera at all? If it is a black window, maybe the brightness on the camera is too low (seems to be a common complaint among spca5xx users.) Shine a bright flashlight into it while looking at the black window, and let me know if it registers any light.

09-21-2004 12:24 AM

Yes, I got IC100 and it works. But xawtv, spcagui and gnomemeeting shows it as IC150. As long as it works, I got no problem. The only problem is that the picture's quality is very poor. I need to increase the sharpness. Anyone got any idea how to increase the sharpness. I tried to increase the frame rate but no success.

And with gnomemeeting, it does work but only if I work as root. Its able to detect the webcam working as a normal user but no picture. Not a brightnes issue.

Please, any pointers on how to increase the sharpness of the image.

vijay.

You definitely don't have the kernel source, then, accourding to the output. Try to urpmi the kernel-source. You will need that to compile.

Also, it looks like the patch command was not run right, did you run patch spca50x.c spca50x_ic150.patch?

Regretfully, i don't have any pointers on how to update the sharpness software-wise. my IC150 has a manual focus around the lens, I assumed that your IC100 would too.

I have e-mailed you a copy of the patched drivers. Do all the following commands as root:

Code:

urpmi kernel-source

This will install the kernel source, which is needed to compile. Install any dependencies listed.

Once this is complete, do the following:

Code:

cd /lib/modules/2.6.3-7mdk

ln -s /usr/src/linux-2.6.3-7mdk build

This will create the symbolic link for the "build" directory.

Next, change to the folder you downloaded the tar file to and do the following:

Code:

tar xzf spca5xx-10092004-patched.tar.gz

cd spca5xx-10092004-patched



make clean

make

make install

The IC150 should work now.

If you have gnomemeeting installed (I think MDK does this by default), you may even see a shortcut automagically appear on your desktop.

Please let me know of your success or failure.

The install looks good from my perspective... check dmesg to verify that the spca50x driver registered.

If you have xawtv installed, you can try xawtv -hwscan as root and as yourself. If your device is really registered, it should show up there.

Also, try v4l-info, which should give you more info on your devices.

d1l2w3

09-24-2004 11:45 AM

It is working.
Thank you for your time and effort.
Below is what 'dmesg' has to say.
Does the 'kernel tainted' mean anything?

Linux video capture interface: v1.00
spca50x: no version for "struct_module" found: kernel tainted.
/home/don/Documents/spca5xx-10092004-patched/drivers/usb/spca50x.c: USB SPCA5XX camera found. Type MicroInnovation IC150 (SPCA561+PB100)
/home/don/Documents/spca5xx-10092004-patched/drivers/usb/spca50x.c: [spca50x_probe:7323] Camera type GBRG

I have another problem now.
I don't know if any of what I did caused it.
I use KDE. However, after getting gnomemeeting working an icon for gnomemeeting appears on one of my desktops and that desktop is now Gnome whereas the others are KDE. Seems weird to me.

Anyway, that's another matter.
Once again I thank you.
dlw

wytiger

09-24-2004 01:20 PM

My pleasure. I'm glad that we were able to get it working! :)

As far as the 'kernel tainted' message is concerned, I wouldn't worry too much. That message is typically associated with non-GPL code being inserted into the kernel. While the spca50x driver is GPL, it does not explicitly state it, which may be the reason for the message.

Enjoy your webcam! :D
