           Summary: Memory leak parsing index chunk of Real Media mux files
                    (rmdemux.c)
           Product: GStreamer
           Version: 0.10.4
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: minor
          Priority: Normal
         Component: gst-plugins-ugly
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: roland.kay at ox.compsoc.net
         QAContact: gstreamer-bugs at lists.sourceforge.net
     GNOME version: 2.11/2.12
   GNOME milestone: Unspecified


Please describe the problem:
When parsing an index header chunk gst_rmdemux_parse_indx_data() uses
g_malloc()
to allocate a GstRMDemuxIndex structure and stores the pointer in the relevant
GstRMDemuxStream structure in GstRMDemux. However, in gst_rmdemux_reset() only
the pointers to GstRMDemuxStream are freed (using g_free()) and any pointer
these structures contain are leaked.

Steps to reproduce:
1. Play http://samples.mplayerhq.hu/real/AC-sipr/autahi-vox.rm in any app that
uses GStreamer under valgrind.


Actual results:
==22890== 1729 (1644 direct, 85 indirect) bytes in 3 blocks are definitely lost
in loss record 25 of 26
==22890==    at 0x1B8FF8A6: malloc (in /usr/lib/valgrind/vgpreload_memcheck.so)

Expected results:


Does this happen every time?
