tcpclientsrc and mpegtsdemux

[Bernhard Graaf]

Hi,

 

I need help to generate my own ,C'-Program from a running pipe:

 

gst-launch-0.10 tcpclientsrc host='192.168.1.3' port=8080 ! mpegtsdemux
name=demux ! queue ! mpeg2dec ! xvimagesink force-aspect-ratio=TRUE demux. !
queue ! mad ! alsasink

With this pipe, I have no problem. It's running very well.

 

But if I try to compile this pipe in my own program, I'll get no results.

#include <stdio.h>

#include <unistd.h>

#include <gst/gst.h>

#include <glib.h>

 

 

GstElement *tv_pipe, *tv_source, *tv_mux, *tv_queue, *tv_v_dec, *tv_v_sink,
*tv_a_dec, *tv_a_sink;

GstBus *tv_bus;

GMainLoop *loop;

 

static gboolean

tv_bus_call (GstBus     *tmp_bus,

          GstMessage *msg,

          gpointer    data)

{

  GMainLoop *loop = (GMainLoop *) data;

 

  switch (GST_MESSAGE_TYPE (msg)) {

 

    case GST_MESSAGE_EOS:

      g_print ("End of stream\n");

      break;

 

    case GST_MESSAGE_ERROR: {

      gchar  *debug;

      GError *error;

 

      gst_message_parse_error (msg, &error, &debug);

      g_free (debug);

 

      g_printerr ("Error: %s\n", error->message);

      break;

    }

    default:

      break;

  }

 

  return TRUE;

}

 

 

int init_gst()

  tv_a_sink     = gst_element_factory_make ("alsasink", "tv-a-sink");

    if(!tv_a_sink) g_printerr("TV-Audio-Sink not created\n");

 

 

  tv_bus = gst_pipeline_get_bus (GST_PIPELINE (tv_pipe));

  gst_bus_add_watch (tv_bus, tv_bus_call, loop);

  gst_object_unref (tv_bus);

 

  gst_bin_add_many (GST_BIN (tv_pipe), tv_source, tv_mux, tv_queue,
tv_v_dec, tv_v_sink, tv_a_dec, tv_a_sink, NULL);

 

  gst_element_link (tv_source, tv_mux);

  gst_element_link (tv_mux, tv_queue);

  gst_element_link (tv_queue, tv_v_dec);

  gst_element_link (tv_v_dec, tv_v_sink);

  gst_element_link (tv_queue, tv_a_dec);

  gst_element_link (tv_a_dec, tv_a_sink);

 

  return 1;

}

 

int send_tv()

{

  gst_element_set_state (tv_pipe, GST_STATE_NULL); 

 

  g_object_set (G_OBJECT (tv_source), "host", "192.168.1.3", NULL);

  g_object_set (G_OBJECT (tv_source), "port", 8080, NULL);

 

  g_print ("Now playing: TV\n");

  gst_element_set_state (tv_pipe, GST_STATE_PLAYING);

 

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

  return 0;

}

 

int main()

{

 

  if(!tv_pipe) init_gst();

  send_tv();

  g_main_loop_run (loop);

  return(1);

}

 

-------------------------

I there anybody how can tell me what's wrong with this program?

 

 

Thank's a lot for helping!!!!
