Video Size problem

[TheMasterRoot]

Hello i was trying to chance the video size to:

cap.set(cv2.CAP_PROP_FRAME_WIDTH, 1280)
cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 720)

but when i did that the script crashes and when it works all boxes ate distorted.
How can i fix it ?

look the error:

root@jasar-VirtualBox:/home/jasar/head-pose-estimation# ./video_test_shape.py

Traceback (most recent call last):
    File "./video_test_shape.py", line 162, in <module>
        main()
    File "./video_test_shape.py", line 121, in main
        cv2.line(frame, reprojectdst[start], reprojectdst[end], (0, 255, 0))

OverflowError: signed integer is greater than maximum

You can just wrap the cv2.line() call in a try block.

You’ll need to calibrate the camera (see cv2.calibrateCamera()).
