Can the QuickCam work using the video4linux Interface?

This Anonymous Coward asks a question related to an older question on Video Converencing with a twist: "What software is written to capture from the Quickcam using the video4linux interface? I can only find bttv which is for video in a window I believe. I am looking for something like xfqcam but which uses the video4linux interface. Quickcam detection seems to really suck under linux especialy with the user level programs (xfqcam) and I figured the video4linux interface might work better. " Can anyone help out with some answers?

Quickcam

[Anonymous Coward]

I've got a black&whitey myself, and I couldn't
wait to try it out when I got the new kernel.
All of the user-land qcam programs seem to suck
and crash my computer...

My only suggestion for the bw-qcam.o module is
that they add a insmod-time option so that
I can tell the driver which ports to scan...
As it is now, it scans ALL ports, and my printer
prints a page with a single letter u on it
whenever I load the qcam. grr!! (I don't know
who to send this suggestion to, and I'm not
really good enough to add that to the driver
myself)...

Anyway, I did have to make a device for it..
mknod /dev/video0 c 81 0

Then I wrote a little C program to experiment
with the ioctls described in
/usr/src/linux/Documentation/video/API.html
until I was able to actually capture a picture
from the camera... Its crude, but that's how
I learned, and it works mostly...
(I should make an account)..

Black and white, or color?

[Da w00t]

I just got a black and white quickcam for free, and so far, I've gotten w3cam to somehow work with v4l and give me a completely BLACK image.

I've got no clue. Someone, PLEASE post to this.

Device or resource busy

Right, and what happens when you say:

dmesg | tail

? It should give you some sort of reason.

The reason there is no /dev/video is that
you most likely have not created it :)

For example... MAKEDEV from xawtv (requires bttv support)

-------------->8---------------
#!/bin/bash

function makedev () {

for dev in 0 1 2 3; do
echo "/dev/$1$dev: char 81 $[ $2 + $dev ]"
rm -f /dev/$1$dev
mknod /dev/$1$dev c 81 $[ $2 + $dev ]
chmod 666 /dev/$1$dev
done

# symlink for default device
rm -f /dev/$1
ln -s /dev/${1}0 /dev/$1
}

# see http://roadrunner.swansea.uk.linux.org/v4lapi.shtm l

echo "*** new device names ***"
makedev video 0

--------------.8---------------

Good luck n stuff!
