  GStreamer | gst-python | Ver: 0.10.23
           Summary: Cannot use both playbin and playbin2
           Product: GStreamer
           Version: 0.10.23
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-python
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: olivier.aubert at liris.cnrs.fr
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: 2.25/2.26
   GNOME milestone: Unspecified


The following simple program exhibits an incompatibility between playbin and
playbin2 :
----
#! /usr/bin/python

import gst
import gtk

uri='file:///media/video/Bataille.avi'

p1=gst.parse_launch('playbin uri=%s' % uri)
p1.set_state(gst.STATE_PAUSED)

p2=gst.parse_launch('playbin2 uri=%s' % uri)
p2.set_state(gst.STATE_PAUSED)

gtk.main()
----

It crashes with the following error/warning messages :

/home/oaubert/lang/python/bug.py:14: Warning: cannot register existing type
`GstSelectorPad'
  gtk.main()
/home/oaubert/lang/python/bug.py:14: Warning: g_object_new: assertion

This looks like an error in
gst-plugins-base/gst/playback/gststreamselector.c:gst_selector_pad_get_type,
but it is typical code so I do not know what leads to this.
