Paulo,
You were damn right It was a question of USB port. I tried again on an
USB 2.0 port, here is my new results:
{ pixelformat = 'YUYV', description = 'YUV 4:2:2 (YUYV)' }
{ discrete: width = 160, height = 120 }
Time interval between frame: 1/30, 1/25, 1/20, 1/15, 1/10,
Paulo,
For the moment, you are right ;)
My webcam is connected to an USB 1.1 port. My computer is an old fashion
one, only has USB 1.1 ports. Right now, I am configuring another one which
has USB 2.0 ports. I will give you some feedback as soon as I can.
Hope you are totally right and that it is t
Cédric,
I think I failed to see the obvious.
Make sure your camera is connected to a USB2 hub.
Logitech cameras (and maybe all uvc devices) cut down available resolutions
when pluged to a slower USB1 pipe.

Cédric,
According to logitech:
http://www.quickcamteam.net/devices/logitech_uvc_frame_format_matrix.xls
your camera should support up to 1600x1...@5fps in yuv mode.
However it's only reporting up to 176x144, this is very strange.
I've seen some posts(

Hi Paulo,
I inserted you code into mine. I set:
formatIn = V4L2_PIX_FMT_YUYV
width = 640
height = 480
fps = 30
The result is:
"Requested Format unavailable: get width 176 height 144"
Like I usually got :(
Thank you for trying to help me anyway,

Cédric Hi,
Could you pleaser try the following function, you will have to make the
necessary adaptations to your code.
int set_format(int fd, int formatIn, int width, int height, int fps)
{
struct v4l2_format fmt;
struct v4l2_streamparm streamparm;
int ret=0;
// set format
Hi,
This is my problem, I don't have any errors. V4L2 API says that when you
ask for a Width and Heigth, the driver will give you the max ones below
the values you asked for. Meaning if you ask for 817x616, it will set
800x600 without returning any errors.

Hello everyone,
I'm using this webcam to do some streaming and image analysis.
When using Logitech's driver under MS Window, it works fine. I've access
to all resolutions with the RGB24 format.
The problem is when running under Linux. I'm using uvcvideo driver via
V4L2 but I can't make it work p
