Hi,
sorry if this is not the correct mail list.
I am not sure if this is a bug, if someone can help me ?
I got a Creative Webcam Pro PD1030.
Drivers are loaded :

It seems that the userspace app is trying to free a memory block twice. Only
the author of the application can help to fix this.
This may eventually be caused by some driver bad behavior or OOPS. Do you have
any oops message, if you run "dmesg" ?
About skype, their V4L support is still broken, at least on the versions I
tested here. I have several webcams here. On my tests, it worked only with one
specific model. I suspect that they support only a very few subset of the
supported video formats.
Cheers,
Mauro

I forgot to cc the linux mailing list, so here it is again.
hi Mauro,
thanks for your answer !
I already contacted the authors (Mark,Wallac,Olawlor), but no feedback
yet.
I got no oops message from kernel.

The better is to copy V4L mailing list.

So, this doesn't seem to be a driver issue. I suspect that your userspace app
is trying to configure an unsupported configuration. This driver still
implements the legacy V4L1 API. Maybe converting it to V4L2 would solve your
issues. Another option is to check if gspca driver works with this device.

Mauro

Hi,
lsmod gives :
ov511 77072 0
compat_ioctl32 1408 1 ov511
videodev 27904 1 ov511
v4l2_common 16896 1 videodev
v4l1_compat 14596 1 videodev
This device works with OV511+
(see http://alpha.dyndns.org/ov511/cameras.html).
Difference between OV511 and OV511+ ?
cheers, linuxcbon
