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

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
