Sure, and I am doing that just after I pass the gst_sample_ref() of it's buffer to push_buffer(). So what I have is:

   aSample = get last-sample from sink

   GstBuffer * buffer = gst_sample_get_buffer( aSample );

   gst_app_src_push_buffer( myAppSrc, gst_sample_ref( buffer ) );

   gst_sample_unref( aSample );

But this leaks memory if I don't remove the gst_sample_ref() call.
