Hi,

I have changed the subject to [GEM] if perhaps people have missed
it... it would be great if anyone else is interested in this because
to have a 120fps camera for less than 40$ working in GEM would be
amazing...

When was the las time you tried this driver?

I'm getting one of these cameras at some point this week to try it
out. It seems that with that driver you can get a video0 device, but
you can only change settings when you load the driver and therefore
not through pix_video...

I'll let you know if I have any success.

yeah, that would be really great and also was one of my thoughts when buying that cam. i already tried several resolutions + fps at module load time, wich works for other applications than GEM. that was approximately one week ago. but i'm not sure if it was the latest driver available though. I made a flickr account, so I'll be able to upload some pictures of the errors later.

ok. this is what I get into GEM (pd extended, nightly one or two weeks ago, sorry for not being that precise...), ubuntu 9.04

one "clear" picture from cheese for comparison.

As I'm still on ubuntu 8.04 for work i tried to compile "MT gspca modified driver V0.5" for it, but this kernel seems to old for these modules.

so this is all from ubuntu jaunty 9.04:

when i start rendering i get these messages repeatedly (every frame?) in console output:

VIDIOCSYNC: Invalid argument
VIDIOCSYNC: Invalid argument

VIDIOCMCAPTURE2: Invalid argument

when changing dimen in pix_video:
error: x dimensions too great
error: y dimensions too great

see flickr images for differences when using RGB, grey, YUV

camera has been set to 640x480 before. I also tried different videomode settings at module load time, without difference for these errors.

cheers
