reference count of gstreamer elements not decresing

[devil coder]

I have a use case of restarting Encoder with different resolution but the
reference count of all elements is not decreasing even after calling stop
function(gst_object_unref() & g_main_loop_unref())..


I have added Initialization function ,start function and stop function sudo
code. for reference.

I am using g_main_loop_new and  gst_parse_launch() API's to create element
then factory API's

Its working fine but reference count is not decrementing.

start       --> restart
wavenc0 --> wavenc1, similarly all the elements


COMMAND cPipeline_Desc




INITIALIZATION funtion


        bus = gst_pipeline_get_bus(GST_PIPELINE(m_pstGstConfig->pipeline));
        gst_bus_add_watch(bus, bus_call, m_pstGstConfig->loop);
        gst_object_unref(bus);

        /* Set the pipeline to "playing" state*/
        gst_element_set_state(m_pstGstConfig->pipeline, GST_STATE_PLAYING);
       
       
       
        RUN function
        if (m_pstGstConfig->loop != NULL)
        {
                printf("\n g loop running \n");
                g_main_loop_run(m_pstGstConfig->loop);
        }
       
       
        STOP function
                       
               
                Problem:
                1) I have a use case of restarting Encoder with different resolution but
the refrence count is not decreasing even after calling stop function
               
                1st Start

Setting pipeline state to NULL state won't remove elements from the pipeline.
gst_element_set_state(m_pstGstConfig->pipeline, GST_STATE_NULL);

unref of the object will unref all the elements.
gst_object_unref(GST_PIPELINE(m_pstGstConfig->pipeline));

Use gst_bin_remove() function to remove only one element. This function will
reduce the ref count of the element by 1.

Hi ShilVin,

Thanks for your inputs, i did the following but still the reference count is increasing, after restart of encoder.
To create gstreamer elements i am not using API's like  GstElement * gst_element_factory_create ()
GstElement * gst_element_factory_make ().

But instead directly using API's like gst_parse_launch() , g_main_loop_new() and g_main_loop_run().
Maybe there is different way of Unreferencing the Gstreamer Elements ? ?

     
 // Create gstreamer loop
        m_pstGstConfig->loop = g_main_loop_new(NULL, FALSE);
        sVideoAudioCmd = EncCommand_line();
       
        /* Create gstreamer elements */
        m_pstGstConfig->pipeline = gst_parse_launch(m_pstGstConfig->cPipeline_Desc, &gError);
       g_main_loop_run(m_pstGstConfig->loop);

Unreferencing

                gst_element_set_state((GstElement *)m_pstGstConfig->pipeline, GST_STATE_NULL);
                gst_object_unref(GST_PIPELINE(m_pstGstConfig->pipeline));
                m_pstGstConfig->pipeline = NULL;

       
                /* Main Loop */
                g_main_loop_quit(m_pstGstConfig->loop);
                g_main_loop_unref(m_pstGstConfig->loop);
                m_pstGstConfig->loop = NULL;

Can anyone help me to solve the issue , i have  attached the Debug log with level 4 {GST_DEBUG=4}, where i am restarting the Encoder 3 times (i called the above code 3 times including Unrefrenceing code) The Reference count value is 0,1,2 in debug log
