           Summary: liveadder has a memory leak
    Classification: Platform
           Product: GStreamer

Created an attachment (id=185434)
 --> (https://bugzilla.gnome.org/attachment.cgi?id=185434)
valgrind output.

Nature of the bug:

When I check the memory usage of the gst-launch command as described below
(using top), I see the memory usage increases from 1.2% to 8% when streaming
one mp3.
The memory "leaks" only when the data stream is active and when the liveadder
plugin is in the pipeline.

In the end (after streaming several mp3's) the process is killed by the OS.

This is the command that causes the memory leak:
gst-launch-0.10 -v udpsrc port=5000
caps="application/x-rtp,media=(string)audio, clock-rate=(int)44100,
channels=(int)2, payload=(int)96" ! gstrtpbin ! rtpL16depay !
audioconvert ! audioresample ! liveadder ! alsasink


To stream audio to this pipeline, use the following gst-launch command (which
does not have any problems)
gst-launch -v filesrc location=DownUnder.mp3 ! mad ! audioconvert !
audio/x-raw-int,channels=2,rate=44100 ! rtpL16pay ! udpsink host=localhost
port=5000

My system configuration:

UBUNTU 10.04 LTS

Initial bug found with the following packages installed via the Ubuntu package
manager:
gstreamer 0.10.28
base 0.10.28
good 0.10.21
bad 0.10.18
ugly 0.10.14

Bug reproduced with latest packages downloaded from
http://gstreamer.freedesktop.org/src/
These are compiled by me. 
gstreamer 0.10.32
base 0.10.32
good 0.10.28
bad 0.10.21
ugly 0.10.17


The command that caused problems is "valgrinded" using the gstreamer
suppression file found at:
http://cgit.freedesktop.org/gstreamer/common/plain/gst.supp

See attachement for valgrind output.
