Hello,

I work with Opencv on ubuntu. I get a simple camera. I get a preview on the image on guvcview and I have a full hd resolution from my camera. When I open a videocapture on opencv the resolution is reset to 640x480.

Why this append? Can I change the resolution of my device on opencv?

Can someone give me explainations about that?

i don't know, what gucview does, but usually, there's a difference between single shot and continuous deliverance capabilites with usb webcams

also, the high resolution for a single image might be just "emulated". please visit the webpage of your webcam, and read the fine print

CAP_PROP_FRAME_WIDTH Width of the frames in the video stream. CAP_PROP_FRAME_HEIGHT Height of the frames in the video stream.
