Youtube-dl删除，没有pafy来流式传输youtube视频

Question

今年我开始使用python，我正在开发一个音乐播放器，它可以在youtube上播放视频，而不需要下载视频。我正在使用tkinter for the gui，vlc来生成一个新的窗口，pafy来从youtube获取视频。自从youtube-dl的关闭政策以来，我已经下载了31.10版本的youtube-dlc，但我的程序显示pafy已不复存在……有没有办法在没有pafy的情况下做同样的事情呢？

def set_media(self):
        url = "youtube url"
        # creating pafy object of the video 
        video = pafy.new(url) 

        # getting best stream 
        best = video.getbest() 

        # creating vlc media player object 
        self.media = vlc.MediaPlayer(best.url)
self.get_media.play() 

我已经尝试过了：

import vlc
import time


url = "https://www.youtube.com/watch?v=s5TIulzXoXo"
instance = vlc.Instance()
media = instance.media_new(url)
player = instance.media_player_new()
player.set_media(media)
player.play()

time.sleep(1.5)
duration = player.get_length() / 1000
time.sleep(duration)

...but返回0，不播放。看起来球员不能得到媒体的支持。你认为如何？谢谢!

您需要解析媒体并播放其第一个子项。

试一试

url = "https://www.youtube.com/watch?v=s5TIulzXoXo"
instance = vlc.Instance()
media = instance.media_new(url)
media.parse()
subitems = media.subitems()

player = instance.media_player_new()
player.set_media(subitems.first()) // select first subitems
player.play()
