Python绑定-播放播放列表

Question

我想知道是否可以使用.m3u打开(播放)音乐播放列表( vlc.py文件)？我找了一个答案，但找不到。我成功地播放了一个简单的mp3文件，甚至是一个mp3流，但是我对播放列表没有任何进展。你能帮我，给我一些示例代码吗？我希望能够通过我的python程序中的轨道(下一个和以前)。先期

Answer 1

这里有一个"very“的粗略模拟，它是我为其他代码编写的，适合您的问题。

它应该允许您使用vlc.py播放流音频、m3u音频播放列表和mp3文件。

正如我所说的，这是非常的粗略代码，但是它应该指向正确的方向。

希望能帮上忙。

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')

只要改变路径，你就可以走了..

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()

创建一个对象

player = VLC()

添加播放列表

player.addPlaylist()

放这首歌

player.play()
time.sleep(9)

放下一首歌

player.next()
time.sleep(9)

暂停这首歌

player.pause()
time.sleep(9)

继续唱这首歌

player.play()
time.sleep(9)

前歌

player.previous()
time.sleep(9)

停止这首歌

player.stop()
