Issue in Seek operation using Gstreamer

Hi All,

I am implementing seek within playback using gstreamer playbin2 element. Following is code snippet:

// --------------- Main Function ----------------//

    g_object_set (playbin2, "uri", "file:///tmp/sample.ogv", NULL);

    GstBus *bus = NULL;
    bus = gst_element_get_bus (playbin2);
    gst_bus_add_watch (bus, my_bus_callback, NULL); // Call back function to handle messages
    gst_object_unref (bus);

    GStaticRecMutex my_mutex = G_STATIC_REC_MUTEX_INIT;
    GstTask *InputTask = gst_task_create(InputTaskFunction,NULL);  // Function to interact with playbin2
    gst_task_set_lock(InputTask,&my_mutex);

    /* Start playing */
    ret = gst_element_set_state (playbin2, GST_STATE_PLAYING);
    if (ret == GST_STATE_CHANGE_FAILURE) {
        g_printerr ("Unable to set the pipeline to the playing state.\n");
        gst_object_unref (playbin2);
        return -1;
    }
    start = 1;
    gst_task_set_state(InputTask,GST_TASK_STARTED);

    loop = g_main_loop_new (NULL, FALSE);
    g_main_loop_run (loop);
// ----------------------------- End Main ----------------------------//

// -------------- Interaction function -----------------//

void  InputTaskFunction          (void *data)
{
    while (start){
        char ch;
        g_print("waiting for input\n");  // Accepting input from console (stdin)
        scanf("%c",&ch);
        switch (ch) {
            case 'q':
                gst_element_set_state (GST_ELEMENT (playbin2), GST_STATE_NULL);
                start = 0;
                g_main_loop_quit (loop);
            break;
            case 's':
            {  // Seeking to 10th second of video file
                gst_element_seek (playbin2, 1.0, GST_FORMAT_TIME, GST_SEEK_FLAG_FLUSH, GST_SEEK_TYPE_SET,
                        10*GST_SECOND, GST_SEEK_TYPE_NONE,  GST_CLOCK_TIME_NONE);
            }
            break;
            default:
                g_print("Invalid Operation.\n");
        }
    }

}

I have tested same code on desktop machine, where this works fine, resuming playback from 10th seconds of video file whenever user inputs 's'  (seek) through console.

But when I tested same code on dm814x EVM board, the video got frizzed as soon as you send seek event (EZSDK-5.03.01.15). 

Am I missing any configuration on EVM, which is causing this issue?

Also I observer high CPU and my gstreamer application stops working whenever I tried increasing gstreamer debug level more than 0 (using GST_DEBUG environment variable). How one can increase gst debug level on EVM board?

Thanks,
