我有多首歌曲正在播放器中加载并排队,但是播放器在第一首歌曲播放后停止播放,尽管我认为文档应该是自动的,但我必须使用next_source()手动强制下一首歌曲。
我正在运行Python 3.7.1和Pyglet 1.3.2,已经对文档进行了搜索,并尝试了不同的数据排队方法。我不确定文件是否会完全播放,尽管我不确定第一首歌曲是否会播放完。
chosenDirectory = ""
cSong = ""
cSongIndex = 0
player = pyglet.media.Player()
songList = []
def chooseDirectory():
global chosenDirectory
chosenDirectory = tk.filedialog.askdirectory(initialdir="/")
lbl.configure(text=chosenDirectory)
listBox.delete("0", "end")
def listFiles(dir):
global songList
songList = []
files = os.listdir(dir)
for x, file in enumerate(files):
filePath = chosenDirectory + "/" + file
if not os.path.isdir(filePath):
fileExt = file.split(".")[1]
if fileExt == "mp3" or fileExt == "wav":
listBox.insert(x, file)
songList.append(filePath)
listFiles(chosenDirectory)
class mediaControls:
def curSelect(self, info):
global cSong
if listBox.curselection() != ():
selected = listBox.get(listBox.curselection())
if selected != cSong:
cSong = selected
cSongIndex = listBox.curselection()[0]
self.playList()
def playSong(self):
if not player.playing:
player.play()
elif player.playing:
player.pause()
def playList(self):
for song in songList:
music = pyglet.media.load(song)
print(music.duration)
player.queue(music)
self.playSong()
def playNextSong(self):
player.next_source()
def playNewSong(self):
global cSong
global cSongIndex
cSongIndex = cSongIndex + 1
cSong = listBox.get(cSongIndex)
self.playSong()
我的预期结果是,在循环播放所有歌曲之前,它们会进入队列,然后再继续播放下一个歌曲,

我想谈谈global
的使用,因为您似乎已经解决了它无法继续播放的问题。通过使状态成为类的一部分,可以消除对global的所有使用。当应用程序运行时,它将创建该类的实例,该实例在程序运行的整个过程中都存在。考虑以下。
它不起作用,因为您没有包含整个脚本。 listBox
似乎丢失了,也应该是实例成员。
class mediaControls:
def __init__(self):
self.chosenDirectory = ""
self.cSong = ""
self.cSongIndex = 0
self.player = pyglet.media.Player()
self.songList = []
def chooseDirectory(self):
self.chosenDirectory = chosenDirectory = tk.filedialog.askdirectory(initialdir="/")
lbl.configure(text=chosenDirectory)
listBox.delete("0", "end")
songList = []
files = os.listdir(chosenDirectory)
for x, file in enumerate(files):
filePath = os.path.join(chosenDirectory, file)
if not os.path.isdir(filePath):
fileExt = file.split(".")[1]
if fileExt == "mp3" or fileExt == "wav":
listBox.insert(x, file)
songList.append(filePath)
self.songList = songList
def curSelect(self, info):
if listBox.curselection() != ():
selected = listBox.get(listBox.curselection())
if selected != self.cSong:
self.cSong = selected
self.cSongIndex = listBox.curselection()[0]
self.playList()
def playSong(self):
if not self.player.playing:
self.player.play()
elif self.player.playing:
self.player.pause()
def playList(self):
for song in self.songList:
music = pyglet.media.load(song)
print(music.duration)
self.player.queue(music)
self.playSong()
def playNextSong(self):
self.player.next_source()
def playNewSong(self):
self.cSongIndex = self.cSongIndex + 1
self.cSong = listBox.get(self.cSongIndex)
self.playSong()

因此,事实证明我期望队列能够处理所有事情,而没有意识到pyglet.app.run()命令实际上是使所有事件开始的原因。不使用它(因为它被阻塞了),我只需要on_eos()来调用next_source()函数并获得相同的结果即可。
