Memory Leak in basic Gstreamer pipeline code.

[Shrishty Deorari]

Hi

I have a querry regarding the memory leak in the gstreamer pipeline.

I am trying to run a Gstreamer pipeline code in a loop:

The simpler version of my code: Reads the video file and displays on the screen using xvimagesink.

Now for every Iteration or loop my memory increases by +.2 . This does'nt seem such a big issue here but when I run this for a log run like over night this memory leak issue becomes big.

I am doing gst_object_unref at all the possible places i could. Please have a look at mini version of my whole program, here also problem is same. Please let me know if I am missing to clear out any memory.

I have attached the File below.

Did you try running the code under valgrind? Using that, and looking at
the definitely/indirectly lost entries is usually helpful. There will be
a number of false positives, some of which can be suppressed with the
suppressions file in the common/ directory in the gstreamer sources.

With a quick run of your code over 2 iterations, I see no leaks.

Hi,

I also tried with valgind using the follwoing command:
G_SLICE=always-malloc G_DEBUG=gc-friendly  valgrind -v --tool=memcheck --leak-check=full --num-callers=40  --log-file=valgrind.log ./gstapp

Where gstapp is my executable.

I have attached the valgrind logs.

I can see that the memory leak is happening at 3 places:

While creating the plugins and somewhere in GLIB.

Please check line number : 4769, 4787,5510.

Those seem to be static initialisation (like the rest of the things in
the log).

Try using a suppression file, there is a lot of false positive
otherwise.
