[gst-devel] GstElement *thread

[<ba...@16...>]

 Hi,
 I am learning GStreamer, reading theGStreamer Application Development Manual (0.10.12.1),and there is a sample in Chanpter20.'XML in GStreamer' in the Manual about thread element.
part of sample code below:
******************************************************************************************
 ..........
 GstElement *thread, *thread2; /* create a new thread to hold the elements */
 thread = gst_element_factory_make ("thread", "thread");
 g_assert (thread != NULL);
 thread2 = gst_element_factory_make ("thread", "thread2");
 g_assert (thread2 != NULL); .........
******************************************************************************************
when i excute this program, the value of thread and thread2 are both 0,
use "gst-inspect thread",the result is "no such element or plugins".
I don't know how to slove this problem,could somebody help me?
Thanks!
