Webcam

Intel CS110 is an old webcam. The driver is included with Debian. However, I can't get any image from it. I tried webcam which returns "can't get rgb24 data", streamer which gives "neither audio nor video format specified/found", and gqcam which gives an image that doesn't make any sense. This camera works in Windows XP. Any ideas or experience to share?

I have Logitech Pro3000 and when I plug in the webcam seems everything OK,lsusb and lsmod I can see the system detect the webcam, but when I run the "motion" it shows that it has problem connect to /dev/video0.

So finally I compiled all the modules and installed then "motion" works fine..

hope it helps.

Thanks for your response. Did you just recompile "motion" and its dependencies, or did you recompile the driver? The reason I ask is that I notice something else when I try gqcam

Output of dmesg afterI plug in the camera

usb 1-1.4: new full speed USB device using orion-ehci and address 6
gspca: probing 8086:0110
spca508: Webcam Vendor ID: 0x8086
spca508: Webcam Product ID: 0x0110
spca508: Window 1 average luminance: 0
gspca: video0 created

Output of dmesg when after I ran "gqcam -v /dev/video0 -a -d test.jpg -t JPEG -i YUV". (-i RGB also gives me the same thing).

gspca: bandwidth not wide enough - trying again

What do you think? Is this more likely to be a driver error or a software error? If you think it is a driver error, how can I confirm it is a driver error?

Hi EWTUC
I really don't know about Linux much...

I didn't recompile "motion" ,I installed by apt-get

I have 3 logitech webcams but only the oldest one Pro3000 won't work,
So I downloaded the kernel and follow the infomation how to compile the module

I compiled it on my Dockstar, it tool long time to finish but it solved my problem.

Hi EWTUC,

I have the same problem and I think it is as explained here :
http://osdir.com/ml/linux-media/2009-06/msg00927.html

I'm still figuring a way out though...

Hello EWTUC,

I also had a problem with an old WebCam, which was not able to deliver JPG compressed pictures, just raw image data.
I figured that out with the utility uvccapture (Debian Squeeze package).

Have a look also at http://www.embeddedlinuxprimer.com/sn9c20x
That raw image data can be converted with the CPU to a JPG picture, but the CPU load is heavy.

Regards, Rudolf

Probably not a USB bandwidth problem:
I tried emDebian running off NAND with only webcam attached (no usb stick or any other usb device attached) and still get the weird looking images when I manage to get an image.

I remember webcam compatibility page has listed Intel CS110 as YUV, so I am going to try Rudolf's suggestion next. I'll let you know what happens.

Thanks for all your help so far.

Hi Rudolf,

is "apt-get install libv4l-ruby1.8", the library you are talking about for converting YUV raw image to JPEG? I can't seem to find "v4l2convert.so" anywhere after installing libv4l-ruby1.8.

Hello EWTUC,

I have not tried the conversion, because I got striped pictures only. If I waved a hand in front of the camera I could see a moving, but that's it.
The CPU load (DockStar) in YUV streaming (5 fps) was 30% at 320 x 240 pixel and 100% at 640 x 480 pixel.

So I gave up, not trying the YUV-JPEG conversion. I the past I made bad experience with CPU load on a low performing CPU (NSLU2, CPU 266 MHz) with picture modification (date/time stamp overlay in a JPG picture).

I think it is better to buy a cheap new WebCam, which has JPEG conversion on board. At older WebCams the conversion was not possible, because of the lack of chip capability, but manufactures do not like to talk about.

Regards, Rudolf

Hello, Following this forum, I can steam video by motion or mjpg_streamer. However, there is no sound streamed. My webcam has mic built-in, I am wondering if any one know how / which software can stream both video and audio. dmesg shows my webcam idVendor=046d, idProduct=09c1, and

Thanks.

Hello Rufus,

VLC should do so, but I do not know the parameter setup.
VLC is both a streaming server and client, beside of being a media player.

In order to use VLC as a streaming client for mjpg-streamer, setup:
In the menu "media/open network stream/network protocol" you enter the address
e.g. http://192.168.17.92:8008/?action=stream and click on play.

I f you figured that out, please let me know.

Regards, Rudolf

Thanks for your suggestion, Rudolf.

I am trying to use vlc, however, I cannot even stream video. I use
cvlc -vvv v4l2:///dev/video0:height=240:width=320 --sout '#rtp{mux=ts,dst=192.168.1.104,port=8081}' --ttl 12

Hello Rufus,

I can only google: cvlc streamer webcam audio:
