It is a good idea to check GST_PLUGIN_PATH and PATH are corect. You must set GST_PLUGIN_PATH to the directory where your libgstplaybin.dll lives.

I've got a very tiny app: int main(int argc, char* argv[]) {     gst_init(NULL, NULL);     guint nMajor(0), nMinor(0), nMicro(0), nNano(0);     gst_version(&nMajor, &nMinor, &nMicro, &nNano);     GMainLoop* loop(NULL);     loop = g_main_loop_new(NULL, FALSE);     GstElement* play = gst_element_factory_make("playbin", "play");     g_object_set (G_OBJECT (play), "uri", "C:\\test.mp3", NULL);     ....     return 0; } play is NULL. That's because it can't find the libgstplaybin.dll in C:\Program Files\Common Files\GStreamer\0.10\lib\gstreamer-0.10. If I CD to C:\Program Files\Common Files\GStreamer\0.10\bin and run gst-launch-0.10.exe playbin uri=file://C:\\test.mp3 This works great.  Plays the file and everything.  I think what's happening is that within my app (which is in a totally different directory), it can't find that DLL, and so it can't create the "playbin" element.  I tried copying those DLLs into my application/debug directory but it didn't help, that kept returning NULL. Any help would be great, thanks! -phil </div> <hr size="1"> <a href="http://us.rd.yahoo.com/evt=51201/*http://autos.yahoo.com/new_cars.html;_ylc=X3oDMTE5NWVzZGVyBF9TAzk3MTA3MDc2BHNlYwNtYWlsdGFncwRzbGsDYXV0b3MtbmV3Y2Fy" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)"> Check out </a> the hottest 2008 models today at Yahoo!
