           Summary: Memory Usage  increases considerably when using qtmux
                    to record aac in mp4 format
    Classification: Desktop
           Product: GStreamer
           Version: 0.10.20
        OS/Version: Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad

1) Record a file using qtmux for aac in mp4 format using pipeline
  gst-launch -e audiotestsrc wave=0 ! faac ! qtmux ! filesink location=test.mp4
&

2) Check the memory usage using top command, the memory usage keeps on
increasing.

3) As far as I have understood, we are queuing buffer in
gstqtmux.c:gst_qt_mux_add_buffer() and appending trak samples on to AtomSTBL
holding different trak structures' GList by calling
atoms.c:atom_add_trak_samples(). I have a vague idea that this is for getting
the duration.
[Please correct me if my understanding is wrong].

This can create problems in usecases where maximum heap size gets reached for
example if we record for longer duration say 2-3 hours or even more.


Thanks
Kunal
