Python omxplayer包装器：基于OSC消息显示视频序列

我刚刚使用Python&OMXPLAYER-WRAPPER，一些帮助将非常棒！：）

该项目包括使用TouchOSC向RaspberryPi发送不同的osc消息，然后根据osc消息显示不同的视频序列

总共只有两个视频-->视频1和视频2

TouchOSC布局只有三个按钮-->操作、待机和循环：

• 操作-->它将显示video1，然后显示video2-->video1+循环（video2）的一个循环
• 待机-->它将显示video2-->循环（video2）的一个循环
• Loop-->它将显示VIDEO 1和VIDEO 2-->循环（VIDEO 1+VIDEO 2）的循环

我已经设法分别进行每个交互，但当我按下一个按钮，然后按下另一个按钮时，我会遇到问题。它显示两个视频，或者只是一个缓慢的视频

这是我编写的代码：

from omxplayer.player import OMXPlayer
from pathlib import Path
from time import sleep
import logging
import argparse
import math
import sys
import os
from subprocess import Popen
from pythonosc import dispatcher
from pythonosc import osc_server

movie1 = ("/home/pi/Videos/action.mp4")
movie2 = ("/home/pi/Videos/standby.mp4")

###################  FUNCTIONS

####  action
def playerExit_action1(code):
  playvideo2_action()

def play_action(unused_addr, args, volume):
  if args[0] == "action" and volume == 1.0:
    print("action")
    player = OMXPlayer(movie1, args=['--no-osd', '--no-keys', '-b'])
    player.exitEvent += lambda _, exit_code: playerExit_action1(exit_code)

def playvideo2_action():
  player1 = OMXPlayer(movie2, args=['--no-osd', '--no-keys', '-b'])
  player1.exitEvent += lambda _, exit_code: playerExit_action1(exit_code)


####  standby
def play_standby(unused_addr, args, volume):
  if args[0] == "standby" and volume == 1.0:
    print("standby")
    player2 = OMXPlayer(movie2, args=['--no-osd', '--no-keys', '-b'])
    player2.exitEvent += lambda _, exit_code: playerExit_standby(exit_code)

def playvideo2_standby():
  player3 = OMXPlayer(movie2, args=['--no-osd', '--no-keys', '-b'])
  player3.exitEvent += lambda _, exit_code: playerExit_standby(exit_code)

def playerExit_standby(code):
  playvideo2_standby()


####  loop
def play_loop(unused_addr, args, volume):
  if args[0] == "loop" and volume == 1.0:
    print("loop")
    player4 = OMXPlayer(movie1, args=['--no-osd', '--no-keys', '-b'])
    player4.exitEvent += lambda _, exit_code: playerExit_loop1(exit_code)


def playvideo1_loop():
  player6= OMXPlayer(movie1, args=['--no-osd', '--no-keys', '-b'])
  player6.exitEvent += lambda _, exit_code: playerExit_loop1(exit_code)


def playvideo2_loop():
  player5 = OMXPlayer(movie2, args=['--no-osd', '--no-keys', '-b'])
  player5.exitEvent += lambda _, exit_code: playerExit_loop2(exit_code)


def playerExit_loop1(code):
  playvideo2_loop()

def playerExit_loop2(code):
  playvideo1_loop()



##  OSC
if __name__== "__main__":
    parser = argparse.ArgumentParser()
    parser.add_argument("--ip",
                        default="192.168.1.107")
    parser.add_argument("--port",
                        type=int, default=12000, help=12000)
    args = parser.parse_args()

    dispatcher = dispatcher.Dispatcher()
    dispatcher.map("/btn/push5", play_action, "action")
    dispatcher.map("/btn/push2", play_standby, "standby")
    dispatcher.map("/btn/push4", play_loop, "loop")

    server = osc_server.ThreadingOSCUDPServer(
        (args.ip, args.port), dispatcher)
    print("Serving on {}".format(server.server_address))
    server.serve_forever()

谢谢
