How to avoid "Discont detected" message while pushing data using appsrc

[roonie]

Iam continously pushing data using while loop using the pull method.
i.e when it requires data it emits "need-data" signal.

Below is sample of my code

void gPTP_ISR()
{
        char buffer[MPEG2TS_LOAD_SIZE];
        while(1)
        {
        if ( rcr[WriteIndex].flag  == FALSE )
        {
        memset(buffer,0,sizeof(buffer));
        memset(rcr[WriteIndex].Output_Buffer,0,MPEG2TS_LOAD_SIZE);
        size = fread(buffer,(MPEG2TS_LOAD_SIZE),1,gst_app.file);
        memcpy(&rcr[WriteIndex].Output_Buffer, buffer,MPEG2TS_LOAD_SIZE);
        rcr[WriteIndex].flag  = TRUE;
        WriteIndex   = (WriteIndex + 1) % ( RING_BUFFER_FRAMES);
        count++;
        }
        }

}


static gboolean read_data(gst_app_t *app)
{
        GstBuffer *buffer;
        guint8 *ptr;
         GstFlowReturn ret;
         ptr = g_malloc(MPEG2TS_LOAD_SIZE);
        g_assert(ptr);
        if ( rcr[ReadIndex].flag == TRUE)
        {
        memcpy(ptr,&rcr[ReadIndex].Output_Buffer,MPEG2TS_LOAD_SIZE);
        rcr[ReadIndex].flag = FALSE;
        ReadIndex = (ReadIndex + 1) % ( RING_BUFFER_FRAMES);
        buffer = gst_buffer_new();
        GST_BUFFER_MALLOCDATA(buffer) = ptr;
        GST_BUFFER_SIZE(buffer) = MPEG2TS_LOAD_SIZE;
        GST_BUFFER_DATA(buffer) = GST_BUFFER_MALLOCDATA(buffer);
        ret = gst_app_src_push_buffer(app->src, buffer);
        if(ret !=  GST_FLOW_OK){
                g_print("push buffer returned %d for %d bytes \n", ret,
size);
                return FALSE;
        }
        return TRUE;
}

static void start_feed (GstElement * pipeline, guint size, gst_app_t *app)
{
        if (app->sourceid == 0) {
                GST_DEBUG ("start feeding");
                app->sourceid = g_idle_add ((GSourceFunc) read_data, app);
        }
}

static void stop_feed (GstElement * pipeline, gst_app_t *app)
{
        if (app->sourceid != 0) {
                GST_DEBUG ("stop feeding");
                g_source_remove (app->sourceid);
                app->sourceid = 0;
        }
}

While executing it, Video playback plays normally whereas i keep getting
this below log

I have used filesrc to play but i dont get these logs. Only when i use
appsrc i get these logs.
This doesnt create a problem for video playback,but for my audio playback
there is no audio output and I wonder if this is creating the problem.

Any ideas would be helpful?.
Thanks
