VLC Python doesn't play YouTube video

问题

When trying to play a YouTube URL with VLC media player via the Python bindings, the video does not actually play.

Here is my code which does the playing:

    def play(self, mrl):

    self.instance = vlc.Instance()

    try:
        self.media = self.instance.media_new_location(mrl)
    except NameError:
        print('NameError: %s (%s vs LibVLC %s)' % (sys.exc_info()[1],
                                                   vlc.__version__,
                                                   vlc.libvlc_get_version()))

    self.player = self.instance.media_player_new()
    self.player.set_media(self.media)

    event_manager = self.player.event_manager()
    event_manager.event_attach(vlc.EventType.MediaPlayerEndReached, self.end_callback)

    self.player.play()

    while self.stillPlaying:
        #do nothing
        pass

And I call it like this:

    play("http://www.youtube.com/watch?v=2hP-UGqA1Ek")

If you do use VLC media player to play this type of link, it will 'find' the video and play it. But all that happens with my code is a standard HTTP GET for the page, and a return of the page content from YouTube, but no video.

回答1:

That's because the link you provided is NOT the link to the video. VLC media player can get the actual link to the YouTube video, but libVLC will not do this.

I had the same problem recently but the youtube.lua file seems to have been long fixed.

Thanks to a tip from Rémi Denis-Courmont, one of the VLC developers, I solved this problem by creating a MediaListPlayer and then adding the media (local file or YouTube URL) to the MediaList then associating that to the player. I am not sure why such a convoluted approach is needed, but at least it works for me.

   #movie is the YouTube or a local URL
   media = instance.media_new(movie)
   media_list = instance.media_list_new([movie]) #A list of one movie

   player = instance.media_player_new()
   player.set_media(media)

   #Create a new MediaListPlayer instance and associate the player and playlist with it

   list_player =  instance.media_list_player_new()
   list_player.set_media_player(player)
   list_player.set_media_list(media_list)
