I've got Creative WebCam Live! Chat IM. It is UVC-compatible, but
it's not listed in the supported devices list (
http://www.ideasonboard.org/uvc/#devices ).
One problem: it works with ~10—15 fps and with 800x600 resolution.
Box/pack says Frame rate: Up to 30fps @ 800x600 pixels (Software
Hi,
Did you notice the (Software enhanced) remark ?
This means a lower resolution is used to achieve the 30 fps and then
the windows driver resizes the image frame to 800x600 (through
software).
The linux uvc driver (like any other v4l2 driver) just exposes the
real resolutions and frame rates
I understand that frame can be resized using interpolation by the
userspace software. But fps, how is it possible? This software makes
in-between frames using smth like morphing?
If someone knows how to do that using userspace software in GNU/Linux
— please, let me know.
Best regards,
Doesn't your camera supports 30 fps at a lower resolution than 800x600 ?

I've made mistake in the first message, I'm sorry. My camera works
with 640x480 and ~10—15 fps.
I run mplayer tv:// and see 640x480 resolution and less than 30 fps.
If I run mplayer tv:// -fps 10 — I see the same frame speed.
mplayer tv:// -fps 5 — I really see 5 fps.
I really don't care in
You may need to disable autoexposure.
Could you please try it with guvcview ?
If you could also post the output of 'guvcview --verbose' it would be
great, as it prints out your camera full control list (and supported
framesizes and frame rates).

I run guvcview and picked on show checkbox near frame rate line at
the video files tab. I always see 7 fps at the window's manager
panel. I've tried to set the smaller resolutions than 640x480 and I
got the same result.
I've attached guvcview --verbose output.

Hi!
Bought a Microsoft LifeCam VX-700 today, workes fine right out of the box
using the UVC driver, Device-Id 045e:0770.
(Device has a build-in mircophone which I have not tested yet -- not sure if
mircrophone is UVC-related, is it?)

OK,
So the camera claims to support 640x...@30 fps, but I guess you need
to manually set exposure for that.
Just set the Exposure, Auto control to manual and adjust Exposure
(Absolute) to a level where you get the 30 fps ( the image will
probably get very dark, in this case you will need to use a
