Hi, all:
Thank you for Eric Zhang's help.
I run the command: `gst-inspect mp3parse', and can not find the
element. Now I am reading 《Running and debugging GStreamer Applications》
form
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gst-
running.html. I found the environment variables do not be set, I hope that
is the reason.
Can you tell me how many environment variables should be set and
their value?
Thank you!

Hi, all
Thank you for Eric Zhang?s help yesterday.
I download gstreamer, gtk+, glib, libxml2 to config my Visual
Studio 2008. But when I run the following code I found something different
form it should be.
GstElement *element;
/* init GStreamer */
gst_init (&argc, &argv);
get_default_registry();
/* create element */
element = gst_element_factory_make("mp3parse", "mp3-parser");
if (!element)
{
g_print ("Failed to create element of type
'fakesrc'\n");
return -1;
}
gst_object_unref (GST_OBJECT (element));
The function gst_element_factory_make("mp3parse",
"mp3-parser") return null, and then I called gst_element_factory_find() ,but
return null.
Can someone tell me why? Maybe I need to config some plugins
but I can not find anything about this from internet specifically about the
configuration of Windows environment. I need your help.
Thank you!

Hi, gstreamer-devel:
You can first run the command: `gst-inspect mp3parse' to check whether
this elements exist. If it exists, re-run your program with debug option
open: --gst-debug=3. I think you can figure out the problem in debug infos.
