Additional information about your setup (OctoPrint version, OctoPi version, ...)

Hint logs, in blue, is a link. Click it, and it will tell you where to find them :wink:

When you say 'can't capture image', do you mean that the webcam stream in OctoPrint does not work, or something else trying to take a picture? You can only do one thing at a time.

@Locatelli_Tony By the looks of it, your camera's resolution is 352 x 288 max, so that would be the first thing to fix - you can't get a higher resolution like 640x480. You also need to remove the -y since the log is saying your camera doesn't support that resolution.
Try running with this config:
-r 352x288 -f 10
And then if it does not work, grab the logs again.

Hmm, so after a little searching for the format the driver is providing:

It seems that mjg_streamer just doesn't support this camera, it is a very edge case and so no one can implement it. Strange that it does not support YUV mode too, but hey.

You'll need a different camera, or a different streaming platform for this to work. A 720p USB webcam is not that expensive, it doesn't need to be HQ.

Ok, I understand, Thnks or your help i will change it.
