hi~farsight problem:)

[guoyuehua]

I have realized the function about capturing the picture and transmit it by the command line gst-launch ~but now i want to realize it by a farsight problem~but it has many faults i can not solve these~
If i can have your help ,it is my greatest honor.
my program is as following :


#include <gst/gst.h>


GstElement *main_pipe;
static gboolean
bus_call (GstBus *bus,
GstMessage *msg,
gpointer data)
{
GMainLoop *loop = data;

switch (GST_MESSAGE_TYPE (msg)) {
case GST_MESSAGE_EOS:
g_print ("End-of-stream\n");
g_main_loop_quit (loop);
break;
case GST_MESSAGE_ERROR: {
gchar *debug;
GError *err;

gst_message_parse_error (msg, &err, &debug);
g_free (debug);

g_print ("Error: %s\n", err->message);
g_error_free (err);

g_main_loop_quit (loop);
break;
}
default:
break;
}

return TRUE;
}


int main(int argc,char ** argv)
{

GMainLoop *loop;
//GstBus *bus;
loop = g_main_loop_new (NULL, FALSE);
main_pipe = gst_parse_launch("v4lsrc ! videoscale ! video/x-raw-yuv,width=352,height=288 ! videorate ! video/x-raw-yuv,framerate=20/1 ! videobalance brightness=0.3 contrast=1.5 ! ffmpegcolorspace ! ffenc_h263p ! rtph263ppay ! udpsink host=192.168.1.112 port=5000",NULL);

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

gst_element_set_state (GST_ELEMENT (main_pipe), GST_STATE_PLAYING);
//gst_element_set_state (p1, GST_STATE_READY);


//while (gst_bin_iterate (GST_BIN (main_pipe)));
g_main_loop_run (loop);

g_print ("Returned, stopping playback\n");
gst_element_set_state (main_pipe, GST_STATE_NULL);
g_print ("Deleting pipeline\n");
gst_object_unref (GST_OBJECT (main_pipe));


/* 停止管道处理流程 */
//gst_element_set_state (main_pipe, GST_STATE_NULL);

/* 释放占用的资源 */
//gst_object_unref (GST_OBJECT (main_pipe));
return 0;


//gst_element_set_state (GST_ELEMENT (main_pipe), GST_STATE_NULL);


//g_print ("Normal Program Termination\n");


//exit (0);
}



I can compile the program but when running the faults is so many:

thanks agains.
