[gst-devel] Memory leak problem with souphttpsrc and qtdemux

[tiki_ns]

I have tried adding the queue in front of qtdemux for filesrc and memory leak
is present! If I use long enough file, memory usage rises above 78% and
sometimes the application is killed. The same behavior I observed when I
used souphttpsrc, only now with filesrc the rate at which memory usage rises
is even higher. I recently joined GST world and so I am still not familiar
with it's concept. Is it possible that such memory issue exist in qtdemux
and flvdemux as well? 

One more thing, I am not using the latest version of gst and plugins because
of some stability issues on target platform so I will try to update to
latest one to check if issue still exist. Thank you very much for your
information and support. I will inform you about any progress.

Best regards,
Tiki
