playbin2 element time out from PAUSE to PLAYING state

[Stavros Markou]

Hello @ all,
I am developing a media player class using qt on freescale's  imx515
processor and i am using playbin2 elent to create the pipeline. I am able to
play/stop/pause amy video i want but the problem is that when i am letting a
playlist loop for a long time (> 4Hours) in poll_for_state_change() :

int CGStreamer::poll_for_state_change(GstState sRecState, GstElement *
elem)
{
    GTimeVal tfthen, tfnow;
    GstClockTimeDiff diff;
    GstStateChangeReturn result = GST_STATE_CHANGE_FAILURE;
    GstState current;
    guint32 timeescap = 0;
    gchar *ele_name = gst_element_get_name(elem);

    g_get_current_time(&tfthen);
    result = gst_element_set_state(elem, sRecState);

    if(result == GST_STATE_CHANGE_FAILURE)
    {
        if( NULL != ele_name )
        {
            g_free(ele_name);
        }
        return -1;
    }

    while(1)
    {
        gst_element_get_state(elem, ¤t, NULL, GST_SECOND);
        g_get_current_time(&tfnow);
        diff = GST_TIMEVAL_TO_TIME(tfnow) - GST_TIMEVAL_TO_TIME(tfthen);
        diff /= (1000 * 1000);
        timeescap = (unsigned int) diff;

        if( sRecState == current )
        {
            break;
        }
        else
        {
            if (timeescap > 10000)      /* 10s */
            {
                printf( "\n%s(): Element %s time out in state transferring
from %s to %s\n",
                    __FUNCTION__, ele_name,
                    gst_element_state_get_name (current),
                    gst_element_state_get_name (sRecState) );
                if( NULL != ele_name )
                {
                    g_free(ele_name);
                }
                return -1;
            }
        }
    }

    if( NULL != ele_name )
    {
        g_free(ele_name);
    }

    return 0;
}

I get Element playbin20 time out in state transferring from PAUSE to
PLAYING.

Since i am new to the whole gstreamer environment i was really surprised to
get a timeout since my application waits for EOS before any state change on
the element.
Have you any idea why this might happen ?

Thanks in advance for your help.

Best Regards,

Stavros.
