Hello,
I have been trying to use pygame to access a video frame by frame and extract the pixel values. The frame is correctly rendered. However, numeric and numpy get an array of zeros when I try to get the info from the display. Is this a bug or am I missing something? The code I use is as follows:
import pygame, sys
from pygame.locals import *
filepath = "esponja.mpg"
pygame.init()
pygame.mixer.quit()
pygame.surfarray.use_arraytype("numpy")
movie = pygame.movie.Movie(filepath)
size = w, h = movie.get_size()
screen = pygame.display.set_mode(size)
movie.set_display(screen, Rect((0, 0), size))
def play():
i = 0
frame_number = 0
while(1):
frame_number = movie.render_frame(i)
frame = pygame.surfarray.array2d(screen) #copies
print frame
if frame_number < i:
break
i = i + 1
movie.rewind()
I am using ubuntu 8.10.
Thanks
