Question

我正在使用python中的pyglet包为音乐播放器编写代码。我可以成功地播放一首歌。但是在打电话给pyglet.app.run()之后我无法暂停这首歌。

如果我在呼叫暂停后拨打pyglet.app.run()我无法播放该歌曲。如何在代码中管理播放和暂停？

我的代码：

import pyglet

import time

player = pyglet.media.Player()

player.queue(pyglet.resource.media('1.mp3'))

player.play()

pyglet.app.run()

time.sleep(5)

player.pause()

print player.time()

Answer 1

#This should play the video then pause after 12 seconds of
# play. Stay paused for 4 seconds and play again.
#Note AVbin7 needs to be installed to play mp4s

import pyglet
from time import sleep
vidPath="/home/path/to/file.mp4"
window = pyglet.window.Window()
player = pyglet.media.Player()
source = pyglet.media.StreamingSource()
MediaLoad = pyglet.media.load(vidPath)
pt = 0
player.queue(MediaLoad)
player.play()

@window.event
def on_draw():
    global pt
    window.clear()
    if player.source and player.source.video_format:
        player.get_texture().blit(0,0)
        if player.time >= 12 and pt == 0:
            print("pausing")
            player.pause()
            sleep(4)
            player.play()
            pt = 1

pyglet.app.run()

Answer 2

pyglet.app.run()

此函数是无限循环。你可以创建一个新的线程，你可以睡觉。

class ControllerThread(threading.Thread):
def __init__(self, player):
    threading.Thread.__init__(self)
    self.player = player

def run(self):
    time.sleep(10)
    self.player.pause()

player = pyglet.media.Player()
pyglet.resource.path = [r'path/to/music']
pyglet.resource.reindex()

music = pyglet.resource.media(r'awesomeSong.mp3')
player.queue(music)
player.play()

c = ControllerThread(player)
c.start()

pyglet.app.run()

Answer 3

此代码应该适合您

import pyglet
import threading
import time
class ControllerThread(threading.Thread):
    def __init__(self, player):
    threading.Thread.__init__(self)
        self.player = player
    def run(self):
        self.player.pause()
player = pyglet.media.Player()
pyglet.resource.path = [r'/your/source/path/']
pyglet.resource.reindex()
def muz():
    music = pyglet.resource.media(r'file.mp3')
    player.queue(music)
    player.play()
t=threading.Thread(target=muz)  
a=''
while a!=' ':
   a=raw_input("STOP/Play S/P: ")
   if a=='s':
       c = ControllerThread(player)
       c.start()
   elif a=='p':
       if t.isAlive():
           player.play()
       else:
           t=threading.Thread(target=muz)   
           t.start()
pyglet.app.run()

以下示例（python 3.7，pyglet 1.5.6）使用SPACE暂停/恢复视频播放：

  #create a new discount code
  discount_code = ShopifyAPI::DiscountCode.new
  discount_code.prefix_options = {price_rule_id: @price_rule.id}
  discount_code.code = @price_rule.title
  discount_code.save

如何在pyglet包中使用pause方法
