  GStreamer | gst-plugins-ugly | Ver: HEAD CVS
           Summary: DVD playing on Vista using dvddemux element seg-faults
                    on spu packet
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: critical
          Priority: Normal
         Component: gst-plugins-ugly
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: tshalif at nargila.org
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: Unspecified
   GNOME milestone: Unspecified


Steps to reproduce:
1. The following is a minimal pipeline which will reproduce this bug with
almost any DVD containing spu streams (tested with Harry Potter, Lord of The
Rings and many more)
tanaka at Vista> GST_DEBUG=dvdreadsrc:4,dvddemux:5 ./gst-launch-0.10.exe -v
--gst-plugin-path=../lib/gstreamer-0.10 dvdreadsrc device=d:/ ! dvddemux
name=demux .current_video ! fakesink silent=true
2. The pipeline crash with memory allocation error immediately after the debug
output prints 'we have a subpicture packet,..'

I was only able to reproduce this bug under windows Vista



Stack trace:


Other information:
This due to an omission in gstdvddemux.c to reset a pointer after calling
g_renew. Please see attached patch fixing this problem.
