webcam not working

Post by leandro.cassa »

Hi Folks,

I've been seeking a solution for 2 days now regarding my webcam. My conclusion until now is that the module for uvcvideo and gspca are just not there, but lets start from the beginning.
I went to gstreamer-properties on the video tab and tried to click on test, this is the error I get "Video for Linux 2 (v4l2): Cannot identify device '/dev/video0'."
On the terminal I get:

Code: Select all

Cannot identify device '/dev/video0'. [v4l2_calls.c(493): gst_v4l2_open (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src1:
system error: No such file or directory]
So I thought my driver was in trouble and I ran lsusb to see if the camera was there:

Code: Select all

As you can see it is an integrated camera, I checked a bunch of forums and it seems there was some people with problems due to their kernel version, so just FYI:

Code: Select all

uname -r

I learned that uvcvideo and gspca are the generic drivers for webcams so I tried:

Code: Select all

modprobe uvcvideo
libkmod: ERROR ../libkmod/libkmod-module.c:174 kmod_module_parse_depline: ctx=0xb92b6008 path=/lib/modules/3.2.0-4-686-pae/kernel/drivers/media/video/videodev.ko error=No such file or directory

and

<the list goes on and on...>

Code: Select all

/usr/src/linux-headers-3.2.0-2-common/include/linux/uvcvideo.h
/usr/src/linux-headers-3.2.0-4-common/include/linux/uvcvideo.h
Since I was missing videodev.ko, then I tried:

locate videodev.ko
No results here...

Well, I'm not an expert but it seems to me the module files related to the webcam support are missing. Can someone help me out here?

What version of Mint are you using? I run Mint 13, and my kernel is 3.2.0-52.

If you are using Mint 12, it expired several months ago. If you are using Mint 13, you should keep it updated.

I'm running 13 I guess...

$ cat /etc/issue
Linux Mint Debian Edition \n \l

I'm not 100% sure though, and I just did a big upgrade and my kernel version is still the same and no efforts I did got my camera working.

Thanks in advance

I'm sorry, I have never used Linux Mint Debian Edition. I think it is a semi-rolling release, so Mint's version numbers do not apply.

I'm surprised the kernel stayed the same, it's very old. I was going to suggest a method to upgrade, but first I Googled: lmde kernel upgrade. I didn't find anything encouraging.

You might try running Mint 15 from a LiveUSB or DVD, and see if Cheese will display your mug.
