Why doesn't vlc on pygtk switch to next track?

Question

Python

Hello, I am writing a small player in python using pygtk binding to libvlc.
There is a task at the end of the track to take the next controller il (GetNextTrack function) and play it.
Through the event_manager of the binding, I write the following callback:

def next_track(self,sender):
    fname = vlc_controller.GetNextTrack()['url']
    self.vlc.player.set_media(instance.media_new(fname,'--network-caching 60000'))
    self.vlc.player.play()

But at the end of the current track, this code is hung up on the function call: player.set_media
And, accordingly, it is not played.
Also tried on qtvlc example. the same.
Tell me which way to dig?

Answer 1

You're calling libvlc from libvlc and it's brain-breaking. This is a bug.

Answer 2

Ok, let's say. Then I try now to remove the component in the window of which libvlc is displayed:

  def endCallback(self,event):
    sys.stdout.write('\n\r endCallback')
    sys.stdout.flush()
    self._mainbox.remove(self.vlc)
    self.vlc = None
    self.vlc = DecoratedVLCWidget()
    sys.stdout.write('\n\r recreatePlayer')
    sys.stdout.flush()
    fname = vlc_controller.GetNextTrack()['url']
    self.vlc.player.set_media(instance.media_new(fname,'--network-caching 60000'))
    sys.stdout.write('\n\r after set_media')
    sys.stdout.flush()		
    self.vlc.player.play()
    sys.stdout.write('\n\r afterplay')
    sys.stdout.flush()		

hangs on self._mainbox.remove(self.vlc) i.e. on the removal of the widget from the form in place of which I planned to put a new instance

Damn, even the developers agreed that this is a cant

So far I've done a workaround via vlc.py MediaPlayerList.
After the end of playback, I add the next track to the list. But there are jambs.
1. The first file in the playlist is played 2 times
2. When a file is deleted from the list, the player is still suspended
