Raspberry pi omxplayer包装器+ Gpio

Question

Omxplayer在按下按钮后崩溃，我喜欢用按钮切换电影，这是我到目前为止的代码，但Omxplayer在按下几个按钮后崩溃！我刚接触覆盆子pi和python，一直在寻找修复程序，但找不到任何东西。欢迎任何帮助。

我得到的错误是：

Traceback (most recent call last):
  File "mygpio.py", line 34, in <module>
    player.load(vida)
  File "build/bdist.linux-armv7l/egg/omxplayer/player.py", line 162, in load

import RPi.GPIO as GPIO



#set up GPIO using BCM numbering

GPIO.setmode(GPIO.BCM)
#All Gpio's as input and pull up

GPIO.setup(2, GPIO.IN, pull_up_down = GPIO.PUD_UP)
GPIO.setup(3, GPIO.IN, pull_up_down = GPIO.PUD_UP)
GPIO.setup(4, GPIO.IN, pull_up_down = GPIO.PUD_UP)


player = OMXPlayer(default,args=['--no-osd','--blank'],)

while True:

      if GPIO.input(2) ==0:

           player.load(vida)
           print("gpio 2")
           player.play()
           #sleep(5)

      if (GPIO.input(3) == 0):

            player.load(vidb)
            print("gpio 3")
            player.play()
           # sleep(5)



      if (GPIO.input(4) == 0):
            player.load(vidc)
            print("gpio 4")
            player.play()
            #sleep(5)



GPIO.cleanup()

看起来这是包装器中的一个bug
