Omx播放器填充模式不起作用

Question

正在为树莓派制作视频项目。 试图让视频填满整个屏幕。 当我打电话给omxplayer videofile.mp4 --aspect-mode fill时，它播放得很好。 但是，当我在我的程序中调用它时，纵横比的参数不起作用。

import pygame
import sys
from time import sleep
from omxplayer import OMXPlayer
pygame.joystick.init()
_joystick_right = pygame.joystick.Joystick(0)
_joystick_right.init()
_joystick_left = pygame.joystick.Joystick(1)
_joystick_left.init()
pygame.init()
done = False
button = ''
controller = ''
player = ''
path = 'hankvids/'

movies = [
 'vid1.mp4',
 'vid2.mp4',
]
quit_video = False
while done==False:
  for event in pygame.event.get():
    if event.type == pygame.JOYBUTTONDOWN:
      button = event.button
      controller = event.joy
      if quit_video == True:
        if button == 0 and controller == 0:
          player.quit()
          quit()
        else:
          if player.is_playing():
            player.load(path + movies[controller], pause=False)
       else:
         quit_video = True
         player = OMXPlayer(path + movies[controller], args=["-b --aspect-mode fill"], pause=False)

Answer 1

您需要将命令拆分为单词：args=["-b", "--aspect-mode", "fill"], 。或者，您可以将 CLI 字符串传递给shlex以为您拆分 args 字符串。
