Hi folks,

I have Mandrake 9.0, an ov511 webcam and a headache

I have loaded the drivers for the webcam, usbcore, v4l etc and lsmod dumps the following:

which seems to contain the drivers required.

ls -l /dev/vid* shows:

lr-xr-xr-x 1 root root 10 Jan 27 20:28 /dev/video0 -> v4l/video0

and ls -l /dev/v4l/ gives:

total 0
crw------- 1 jools sys 81, 0 Jan 1 1970 video0

The user and group settings appear to be what Mandrake has decided when dynamically creating the v4l device (jools is my uname).

The relevant parts of dmesg from boot time are:

Running xawtv generates the following output in a terminal:

This is xawtv-3.76, running on Linux/i686 (2.4.19-16mdk)
can't open /dev/v4l/video0: Function not implemented
v4l-conf had some trouble, trying to continue anyway
v4l2: open /dev/v4l/video0: Function not implemented

and /var/log/kernel/errors reports:

Any help appreciated.

Cheers,

jools

Hi,

I'm on a Debian sid kernel-2.4.21-ck3 with the correct modules compiled in.
Drivers for the webcam (ov511) are perfectly installed.
controlled under usbview, demsg, (read bellow)
The webcam is a @#!% Philips TouCam PCVC720k/20.
I've already saw it work fine under Mandrake 9.0 and 9.1.
But now i got a headake.
version: kernel-2.4.21-ck3
drivers version: ov511-1.65

of course the kernel is well configured and of course i RTFM

Ok, i will try the other drivers version. But i someone has any id ...

Hello again,

After 2 aspirines, i found the answer. I used the wrong decompression module.
The good one is ov518_decomp

Now, my modules.conf, with support for color :

vi /etc/modules.conf ======================
alias char-major-81 ov511
above ov511 ov518_decomp
options ov511 compress=1 led=2 fix_rgb_offset=1 mirror=1 ov518_color=1
===================================

For those of you who use debian : add this to automount the module at boot.

vi /etc/modules =========================
ov511
===================================

I've tested it with gnomemeeting, and for the first time ever under linux i talked to someone under netmeeting without any problem.

Now, my usb mouse ...

See ya !
