  GStreamer | gst-plugins-base | Ver: HEAD CVS
           Summary: gst_ogm_parse_stream_header creates fraction value with
                    wrong denominator argument width (64 bits)
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: arkadini at gmail.com
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: 2.21/2.22
   GNOME milestone: Unspecified


Please describe the problem:
gst_ogm_parse_stream pases ogm->hdr.time_unit (which is gint64) directly to the
gst_set_caps_simple for a GST_TYPE_FRACTION value. The arguments are passed
va-style, but the eventual gst_value_set_fraction() expects and receives 32-bit
integers. 

This is wrong, but it's mostly affecting the big endian machines because of the
lack of byte reordering - gst_value_set_fraction() receives the most
significant half of the denominator which will be 0 in most of the cases.
