有gstreamer的库吗？

我想搞一个基于gstreamer的应用，类似gst-launch-1.0，有对应的库吗？还是需要自己移植？

1. #include <gst/gst.h>
   
2. 
   
3. int main (int argc, char *argv[])
   
4. {
   
5.   GstElementFactory *factory;
   
6.   GstElement * element;
   
7. 
   
8.   /* init GStreamer */
   
9.   gst_init (&argc, &argv);
   
10. 
    
11.   /* create element, method #2 */
    
12.   factory = gst_element_factory_find ("fakesrc");
    
13.   if (!factory) {
    
14.     g_print ("Failed to find factory of type 'fakesrc'\n");
    
15.     return -1;
    
16.   }
    
17.   element = gst_element_factory_create (factory, "source");
    
18.   if (!element) {
    
19.     g_print ("Failed to create element, even though its factory exists!\n");
    
20.     return -1;
    
21.   }
    
22.   
    
23.   /* get name */
    
24.   g_object_get (G_OBJECT (element), "name", &name, NULL);
    
25.   g_print ("The name of the element is '%s'.\n", name);
    
26.   g_free (name);
    
27.   
    
28.   gst_object_unref (GST_OBJECT (element));
    
29.   gst_object_unref (GST_OBJECT (factory));
    
30. 
    
31.   return 0;
    
32. }
