            Bug ID: 794551
           Summary: Memory leak in mpegtsmux
    Classification: Platform
           Product: GStreamer
           Version: 1.12.x
                OS: Linux
            Status: NEW
          Severity: major
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org

Under Ubuntu 14.04,  specifying pids in mpegtsmux 
program-map, causes memory leak, e.g. the following pipeline  leaks: (As 
seen by "top")

gst-launch-1.0 videotestsrc is-live=true pattern=zone-plate kx2=20 
ky2=20 kxy=4 kt2=10 ! video/x-raw, format=I420,width=1280,height=720 ! 
videoconvert ! openh264enc ! h264parse  ! muxer.sink_49 mpegtsmux 
name=muxer prog-map=program_map,sink_49=1 ! fakesink

Whereas, this pipeline does not:

gst-launch-1.0 videotestsrc is-live=true pattern=zone-plate kx2=20 
ky2=20 kxy=4 kt2=10 ! video/x-raw, format=I420,width=1280,height=720 ! 
videoconvert ! openh264enc ! h264parse  ! mpegtsmux name=muxer  ! fakesink

It gets a bit more complicated: If pid is a 3 digit number, 
no leaks are detected, i.e., the folowing pipeline does not leak:

gst-launch-1.0 videotestsrc is-live=true pattern=zone-plate kx2=20 
ky2=20 kxy=4 kt2=10 ! video/x-raw, format=I420,width=1280,height=720 ! 
videoconvert ! openh264enc ! h264parse ! muxer.sink_149 mpegtsmux 
name=muxer prog-map=program_map,sink_149=1 ! fakesink

(Similar results holds for msdkh265 encoder.)
