           Summary: SIGSEGV fault in SceneChange element
    Classification: Platform
           Product: GStreamer
           Version: unspecified
        OS/Version: All
            Status: UNCONFIRMED
          Severity: critical
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: vineeth.tm at samsung.com
         QAContact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---


While testing SceneChange element using the following command
gst-launch-1.0 -v filesrc location=../test1.wmv ! decodebin ! videoconvert !
scenechange ! videoconvert ! autovideosink

when gst_video_frame_map() is called, "scenechange->oldinfo" was not populated
first time. Hence it was resulting in SIGSEGV fault.

Hence adding the below statement
memcpy (&scenechange->oldinfo, &frame->info, sizeof (GstVideoInfo));
when scenechange->oldbuf is NULL
