Question

我想知道是否可以打开（播放）音乐播放列表（.m3u文件）使用vlc.py？我搜索了一个答案，但找不到它。我设法播放了一个简单的mp3文件，甚至是mp3流，但我对播放列表没有任何好运。你能帮我一下，给我一些示例代码吗？我希望能够在我的python程序中浏览曲目（Next和Previous）。提前完成了

Answer 1

这是一个“非常”粗略模拟我为其他内容编写的一些代码，适合您的问题。
它应该允许您使用vlc.py播放流式音频，m3u音频播放列表和mp3文件。
正如我所说，它是非常粗糙的代码，但它应该指向正确的方向希望能帮助到你。

import requests
import vlc
from time import sleep
urls = [
    'http://network.absoluteradio.co.uk/core/audio/aacplus/live.pls?service=acbb',
    'file:///home/rolf/test.m3u',
    'file:///home/rolf/happy.mp3',
    'http://statslive.infomaniak.ch/playlist/energy90s/energy90s-high.mp3/playlist.pls',
    'http://streaming.radio.rtl2.fr/rtl2-1-44-128',
    ]

playlists = set(['pls','m3u'])

Instance = vlc.Instance()

for url in urls:
    ext = (url.rpartition(".")[2])[:3]
    test_pass = False    
    try:
        if url[:4] == 'file':
            test_pass = True
        else:
            r = requests.get(url, stream=True)
            test_pass = r.ok
    except Exception as e:
        print('failed to get stream: {e}'.format(e=e))
        test_pass = False
    else:
        if test_pass:
            print('Sampling for 15 seconds')
            player = Instance.media_player_new()
            Media = Instance.media_new(url)
            Media_list = Instance.media_list_new([url])
            Media.get_mrl()
            player.set_media(Media)
            if ext in playlists:
                list_player = Instance.media_list_player_new()
                list_player.set_media_list(Media_list)
                if list_player.play() == -1:
                    print ("Error playing playlist")
            else:
                if player.play() == -1:
                    print ("Error playing Stream")
            sleep(15)
            if ext in playlists:
                list_player.stop()
            else:
                player.stop()

        else:
            print('error getting the audio')

只需更改路径，您就可以开始使用了。

from tkinter import *
try:

    window = Tk()
    some = StringVar()
    a = Entry(textvariable = some)
    a.pack()
    window.mainloop()

    number = float(some.get())
    print(number)
except ValueError:
    print("Invalid Value in The Entry Box")

创建对象

from vlc import Instance
import time
import os

class VLC:
    def __init__(self):
        self.Player = Instance('--loop')

    def addPlaylist(self):
        self.mediaList = self.Player.media_list_new()
        path = r"C:\Users\dell5567\Desktop\engsong"
        songs = os.listdir(path)
        for s in songs:
            self.mediaList.add_media(self.Player.media_new(os.path.join(path,s)))
        self.listPlayer = self.Player.media_list_player_new()
        self.listPlayer.set_media_list(self.mediaList)
    def play(self):
        self.listPlayer.play()
    def next(self):
        self.listPlayer.next()
    def pause(self):
        self.listPlayer.pause()
    def previous(self):
        self.listPlayer.previous()
    def stop(self):
        self.listPlayer.stop()

添加播放列表

player = VLC()

播放歌曲

player.addPlaylist()

播放下一首歌曲

player.play()
time.sleep(9)

暂停歌曲

player.next()
time.sleep(9)

恢复歌曲

player.pause()
time.sleep(9)

上一曲

player.play()
time.sleep(9)

停止播放歌曲

player.previous()
time.sleep(9)
