[gst-devel] why is it not working ?

[Laurent Belmonte]

Hi,

I am writing some code that use gstreamer, but i cant stand why it is
not working :


static void idle(gpointer user_data) {
	gst_bin_iterate( main_bin);
}

static void key_pressed(..) {
	channel = create_channel(id,"/my_song.mp3");

  gst_element_set_state( main_bin, GST_STATE_PAUSED);
  gst_bin_add( main_bin, channel->pipe);

  pad = gst_element_get_request_pad( adder,"sink%d");
  sprintf(buffer,"channel%d",channel->id);

  gst_pad_link (gst_element_get_pad (channel->pipe, buffer), pad);

  gst_element_set_state(main_bin,GST_STATE_PLAYING);
}

static channel * create_channel(int id,const gchar * location ) {
	  sprintf(buffer,"pipeline%d",channel->id);
  channel->pipe = gst_bin_new(buffer);

 sprintf(buffer,"filesrc%d",channel->id);
  channel->filesrc = gst_element_factory_make("filesrc",buffer);

  gst_bin_add( GST_BIN(channel->pipe), channel->filesrc);

  decoder = gst_element_factory_make("mad","mpg123");

  gst_bin_add( GST_BIN(channel->pipe), decoder);

  gst_element_link(channel->filesrc,decoder);

  sprintf(buffer,"channel%d",channel->id);
  gst_element_add_ghost_pad( channel->pipe,
gst_element_get_pad(decoder,"src"),buffer);
  return channel;
}

main() {
	adder = gst_element_factory_make("adder","mixer");
   output = gst_element_factory_make("osssink","output");

    main_bin = gst_pipeline_new("bin");

    gst_bin_add( GST_BIN( main_bin),adder);
    gst_bin_add( GST_BIN( main_bin),output);

    gst_pad_link(gst_element_get_pad(adder,"src"),
		 gst_element_get_pad(output,"sink"));

    gst_element_set_state( main_bin, GST_STATE_PLAYING);
    gtk_idle_add(idle,NULL);

	..
	gtk_main();
return 0;
}

help me please !
