Memory leak in liveadder?

[ej]

Hi,

I'm using the following gst-launch command

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

When I check the memory usage of this process (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.

Can anybody help me or tell me what is wrong?

Does it keep on increasing or does it just stay at 8% ? liveadder has a
queue that you can control with the "latency" property os it can sync up
the various streams. The default 60ms is chosen to be larger than the
common 40ms packet size for RTP. That said 60ms of 44khz 2 channel raw
audio should only be 10kbytes..

I forgot to add the following:

When I leave out the liveadder, the used memory is stable. So I expect a memory leak in liveadder.

Olivier,

Yes it keeps increasing.
start:
1.4% 78760k

after 14 min mp3 streaming
34.2% 53536k

So I lost 25224kbytes

By the way I use bad plugin version 0.10.18 on an Ubuntu system. I see that the latest version is 0.10.21
Would that be the answer?

Hi,

Has anybody an idea what is wrong with liveadder? It is eating all my memory in the following example.
When using valgrind I get a lot of information and a summary.

Please file a bug and attach the whole valgrind log. Please use valgind as below:

G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind --tool=memcheck
--leak-check=full --show-reachable=yes --log-file=valgrind.log gst-launch-0.10
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

Ideally use the gst.supp file from gstreamer git
http://cgit.freedesktop.org/gstreamer/common/tree/gst.supp
