OpenCV (via python) on Linux: Set frame width/height?

Question

I\'m using openCV via python on linux (ubuntu 12.04), and I have a logitech c920 from which I\'d like to grab images. Cheese is able to grab frames up to really high resolut

Answer 1

I had the same problem as you. Ended up going into the OpenCV source and changing the default parameters in modules/highgui/src/cap_v4l.cpp, lines 245-246 and rebuilding the project.

#define DEFAULT_V4L_WIDTH  1920
#define DEFAULT_V4L_HEIGHT 1080

This is for OpenCV 2.4.8
