Could you make a small stand-alone test case that demonstrates this
issue?

Does the leak go away if you remove the

   gst_app_src_push_buffer(myAppSrc, gst_sample_ref(buffer)); 

line?

It could be that the buffer is leaked somewhere downstream of appsrc, or
appsrc doesn't properly clean up pending buffers somewhere in some
cases.
