Changing capture resolution cv2 in python doesn't work

Hi,

I am trying to change the capture resolution in cv2 in python. I already looked up some posts about it, like http://opencv-python-tutroals.readthedocs.org/en/latest/py_tutorials/py_gui/py_video_display/py_video_display.html , but the command sequence there doesn't seem to work for me.

Here is my piece of code:

channel = 0

camera = _cv2.VideoCapture(channel)

camera.set(_cv2.cv.CV_CAP_PROP_FRAME_WIDTH, 1280)

camera.set(_cv2.cv.CV_CAP_PROP_FRAME_HEIGHT, 1024)

print camera.get(_cv2.cv.CV_CAP_PROP_FRAME_WIDTH)

print camera.get(_cv2.cv.CV_CAP_PROP_FRAME_HEIGHT)

And the print out is:

640.0

480.0

Can anyone help me with this issue?

Thanks in advance!
