[gst-devel] code problem.

[Sanjay, A. V <add...@in...>]

Hello,
I am trying to write a mp3 player. I am using gstream for the first =
time. I have written this code snipet. Any help in understanding, the =
reason, why it is behaving , like this, will be very helpful.

GstElement *thread;
gboolean can_quit =3D FALSE;

char URI[500];
void
eos (GstElement *src, gpointer data)
{
  GstThread *thread =3D GST_THREAD (data);
  g_print ("have eos, quitting\n");

  /* stop the bin */
  gst_element_set_state (GST_ELEMENT (thread), GST_STATE_NULL);

  while (!can_quit) /* waste cycles */ ;
  //gst_main_quit ();
}

void UPnPAVTransport_Play(void* upnptoken,unsigned int InstanceID,char* =
Speed)
{
=09
  GstElement *filesrc, *mad, *osssink;
  GstElementState state;
 =20
   printf("Invoke: UPnPAVTransport_Play(%u,%s);\r\n",InstanceID,Speed);

  printf("yahoo!!!!\n");    =20
      =20
 =20
  filesrc =3D gst_element_factory_make("httpsrc", "httpsrc");
  g_assert(filesrc);
  g_object_set(G_OBJECT(filesrc), "location", URI, NULL);

  g_signal_connect (G_OBJECT (filesrc), "eos",
                     G_CALLBACK (eos), thread);

  mad =3D gst_element_factory_make("mad", "mad");
  g_assert(mad);

  osssink =3D gst_element_factory_make("osssink", "osssink");
  g_assert(osssink);

  gst_bin_add_many (GST_BIN (thread), filesrc, mad, osssink, NULL);

  gst_element_link_many (filesrc, mad, osssink, NULL);

  gst_element_set_state (GST_ELEMENT (thread), GST_STATE_PLAYING);

  g_print ("thread is playing\n");

  state =3D gst_element_get_state(GST_ELEMENT (thread));

  printf(" in play, state is %d\n", state); =20

  ( This printf returns the state as GST_STATE_NULL, i.e 1 and not =
GST_STATE_PLAYING, why is this???, the function eos has not been called =
yet).

  can_quit =3D TRUE;
  //gst_main ();

  //gst_pipeline_destroy (thread);         =20
       =20
  printf("yahooagain\n");
=09

	UPnPResponse_AVTransport_Play(upnptoken);
}

Thanks
Sanjay
