Does that help I believe the correct answer is http://code.google.com/p/mp4parser/

To fix the issue you can do The Basics
The H264 compression format is a inter-picture-prediction format. Very simplified, to complete and display a frame, it needs information stored in other frames.

this will help I have some code and I have used it to generate a graph which moves with time. , You miss the part of actually saving the current frame:
frame = getframe(figure(4));
writeVideo(vidObj,frame);

I wish this helpful for you cv2.waitKey(0) waits without timeout, replace it with cv2.waitKey(time_in_msec).
Example for refreshing at about 10Hz:
import numpy
import cv2
from PIL import ImageGrab

while True:
    img = ImageGrab.grab(bbox=(765,155,1135,195))
    img_np = numpy.array(img)
    frame = cv2.cvtColor(img_np, cv2.COLOR_BGR2GRAY)
    cv2.imshow("frame",frame)
    cv2.waitKey(100)

cv2.destroyAllWindows()
