How to load and play a video in pygame

问题

I'm having a problem. I want to load and play a video in pygame but it doesn't start. The only thing that I am seeing is a black screen. Here is my code:

import pygame
from pygame import display,movie
pygame.init()
screen = pygame.display.set_mode((1024, 768))
background = pygame.Surface((1024, 768))

screen.blit(background, (0, 0))
pygame.display.update()

movie = pygame.movie.Movie('C:\Python27\1.mpg')
mrect = pygame.Rect(0,0,140,113)
movie.set_display(screen, mrect.move(65, 150))
movie.set_volume(0)
movie.play()

Can you help me??

回答1:

You are not actually blitting it to a screen. You are also not utilizing a clock object so it will play as fast as possible. Try this:

# http://www.fileformat.info/format/mpeg/sample/index.dir
import pygame

FPS = 60

pygame.init()
clock = pygame.time.Clock()
movie = pygame.movie.Movie('MELT.MPG')
screen = pygame.display.set_mode(movie.get_size())
movie_screen = pygame.Surface(movie.get_size()).convert()

movie.set_display(movie_screen)
movie.play()


playing = True
while playing:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            movie.stop()
            playing = False

    screen.blit(movie_screen,(0,0))
    pygame.display.update()
    clock.tick(FPS)

pygame.quit()

I just got that MELT.MPG from the link provided in the comment. You should be able to simply switch out that string for your actual MPG you want to play and it will work... maybe.
