  GStreamer | gst-plugins-base | 1.0.3

           Summary: Memory allocated by GstVideoDecoder base class is not
                    freed
    Classification: Platform
           Product: GStreamer
           Version: 1.0.3
        OS/Version: Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-base
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: mrubinstein at weather.com

     GNOME version: ---


In gstvideodecoder.c:

A call is made to gst_video_decoder_add_timestamp which allocates a 32 byte
structure and a linked list element.

gst_video_decoder_get_timestamp_at_offset would free this memory, but it
is not called in my test cases.  This would happen in
gst_video_decoder_have_frame, but it is not called.

I'm using the MPEG2 Video Decoder ("avdec_mpeg2video").
I'm pretty sure this applies to other video decoders.

It seems small, but, with overhead, it amounts to several MB/hr.
