dvbbasebin and tcpserversink

[Bernhard Graaf]

Hi, 

I'm a new gstreamer developer and have a small problem with a simple pipe.
If I'm use the pipe: 
"gst-launch-0.10 -m dvbbasebin adapter=1 frequency=12544000
program-numbers=17501 polarity=h symbol-rate=22000 ! tcpserversink
port=8080" 

Then I can see the program (for e.g. with vlc tcp://192.168.1.102:8080) 

If I try to do the same in C-code 
-------- 
int 
main () 
{ 
  GMainLoop *loop; 

  GstElement *pipeline, *source, *sink; 
  GstBus *bus; 

  gst_init (NULL, NULL); 

  loop = g_main_loop_new (NULL, FALSE); 

  pipeline = gst_pipeline_new ("DVB-Streamer"); 
  source   = gst_element_factory_make ("dvbbasebin",       "dvb-source"); 
  sink     = gst_element_factory_make ("tcpserversink", "tcp-output"); 

  if (!pipeline || !source || !sink) { 
    g_printerr ("One element could not be created. Exiting.\n"); 
    if(!pipeline) g_printerr("Pipeline not created\n"); 
    else if(!source) g_printerr("Source not created\n"); 
    else if(!sink) g_printerr("Sink not created\n"); 
    return -1; 
  } 

  g_object_set (G_OBJECT (source), "adapter", 1, NULL); 
  g_object_set (G_OBJECT (source), "frequency", 12544000, NULL); 
  g_object_set (G_OBJECT (source), "program-numbers", "17501", NULL); 
  g_object_set (G_OBJECT (source), "polarity", "h", NULL); 
  g_object_set (G_OBJECT (source), "symbol-rate", 22000, NULL); 
  g_object_set (G_OBJECT (sink), "port", 8080, NULL); 

  bus = gst_pipeline_get_bus (GST_PIPELINE (pipeline)); 
  gst_bus_add_watch (bus, bus_call, loop); 
  gst_object_unref (bus); 

  gst_bin_add_many (GST_BIN (pipeline), 
                    source, sink, NULL); 

  gst_element_link (source, sink); 

  g_print ("Now playing: "); 
  gst_element_set_state (pipeline, GST_STATE_PLAYING); 

  g_print ("Running...\n"); 
  g_main_loop_run (loop); 

  return 0; 
} 

---- 

I got the error: 

Now playing: Running... 
Error: Interner Fehler im Datenfluss. 
(sorry for the German error. it's call something like "Internal error in
data stream") 



If I don't use the 

g_object_set (G_OBJECT (source), "program-numbers", "17501", NULL); 

It's running well, but I need this parameter


Thanks a lot for helping!!
