Switch gst video to some point in another video on pygtk Button press

I'm trying to play a video and have a button that switches the video to a new one, starting the new one at some point other than the beginning. I haven't written much UI or video-related code.

I have the following that kind of works (very trimmed):

class Main(gobject.GObject):
  def __init__(self):
    self.player = gst.element_factory_make('playbin', 'VideoPlayer')
    #.. pygtk UI/Button code

  def next_video(self):
    self.player.set_state(gst.STATE_NULL)
    self.player.set_property('uri', 'next_video_path')
    self.player.set_state(gst.STATE_PAUSED)
    end = time.time() + 1
    while time.time() < end:
      pass
    self.player.seek_simple(gst.FORMAT_TIME, gst.SEEK_FLAG_FLUSH, 100000000000)
    self.player.set_state(gst.STATE_PLAYING)

if __name__ == "__main__":
  Main(sys.argv)
  gtk.main()

A couple points:

Obviously, I'd like a cleaner, more reliable way to do this.

TL;DR: How can I switch from video to video in a pygtk window, starting at an arbitrary point in the video?

Instead of waiting one second, use something like self.player.get_state(timeout=3*gst.SECOND) to wait for the switch to gst.STATE_PAUSED to complete.

The timeout is used because if an error occurs and GStreamer doesn't succeed at changing the pipeline state, a get_state without a timeout will just get stuck waiting forever.
