Question

this erorr message appears on running simple camera capture on Ubuntu with logitech C270 (OpenCV 2.4.2/C++):

HIGHGUI ERROR: V4L/V4L2: VIDIOC_S_CROP

Answer 1

If you just want to get rid of the output quickly and grep -v Corrupt does not work for somehow - like for me - you could also redirect stderr to nothing, e.g.

./my_app 2> /dev/null

python my_app.py 2> /dev/null

This will of course hide other error messages, too.
