VideoCapture.set() not working correctly? #529
Description
Expected behaviour
vc = cv2.VideoCapture(TARGET)
vc.set(cv2.CAP_PROP_FRAME_WIDTH,1920)
vc.set(cv2.CAP_PROP_FRAME_HEIGHT,1080)
vc.set(cv2.CAP_PROP_FPS, 30.0)
vc.set(cv2.CAP_PROP_SATURATION, 50)
vc.set(cv2.CAP_PROP_SHARPNESS,100)
if not vc.isOpened():
sys.stderr.write('could not connect to camera! \n')
sys.exit(1)
while True:
success,frame = vc.read()
if not success:
sys.stderr.write('could not read image from cam \n')
sys.exit(1)
cv2.imshow('my webcam', frame)
# cv2.imwrite('capture_%02d.png' % count,frame)
if cv2.waitKey(1) == 27:
break # esc to quit
cv2.destroyAllWindows()
vc.release()
vc = None
Actual behaviour
only getting 5 fps when should be 30, not sure why? Camera supports 30fps.
