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! -----Original Message----- Message: 1 Date: Tue, 02 Dec 2008 10:32:00 +0900 From: ??? <[hidden email]> Subject: [gst-devel] Help!

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.

To: [hidden email] Message-ID: <[hidden email]> Content-Type: text/plain; charset="gb2312" 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.

Hi, gstreamer-devel:
Sorry guy, Actually I have no experiences on running gstreamer on windows. So you should dig it yourself or ask somebody else. On linux, seems there is no need to set any environment variables. I compiled gstreamer and plugins on linux and install, that's all. Everything works fine.

GStreamer needs to known where its plugins are, you can either : - use the --gst-plugin-path="xxxx" switch of gst-inspect-0.10.exe - set the GST_PLUGIN_PATH environment variable either using Windows' GUI or by setting it by hand at the start of your program (eg. using g_setenv : http://library.gnome.org/devel/glib/unstable/glib-Miscellaneous-Utility-Functions.html#g-setenv) eg. gst-inspect-0.10.exe --gst-plugin-path="c:\\install path\\lib\\gstreamer-0.10" plugin_name I can't remember if you need to escape '\' in the path above, but you may have to.
