org.gstreamer.GstException: no element "filesrc"

[dvrslype]

Yo guys,

i copied my previously working setup to another machine (GIT head of
gstreamer, plugins good, bad, ugly and gl, ffmpeg). Now, when I start
my java app, i get org.gstreamer.GstException: no element
"filesrc" (when launching my pipeline).

Here is my simple code:

package videotest;

import java.awt.BorderLayout;
import java.awt.Canvas;
import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;
import org.gstreamer.Bus;
import org.gstreamer.Element;
import org.gstreamer.Gst;
import org.gstreamer.GstObject;
import org.gstreamer.Pipeline;
import org.gstreamer.interfaces.XOverlay;
public static void main(String[] args) {
args = Gst.init("Swing Player", args);
final String videoLocation = args[0];
SwingUtilities.invokeLater(new Runnable() {

public void run() {
JFrame frame = new JFrame("Overlay Test");
final Canvas canvas = new Canvas();
canvas.setPreferredSize(new Dimension(640, 480));
frame.add(canvas, BorderLayout.CENTER);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);

Pipeline player = Pipeline.launch("filesrc location="
+ videoLocation + " ! decodebin ! ffmpegcolorspace ! glimagesink
name=gl");
bus = player.getBus();
bus.connect(new Bus.ERROR() {

public void errorMessage(GstObject source, int
code, String message) {
System.out.println(source);
System.out.println("Error: code=" + code + "
message=" + message);
}
});
final Element videoSink =
player.getElementByName("gl");
XOverlay.wrap(videoSink).setWindowID(canvas);
player.play();
}
});
}


I run `gst-inspect filesrc` from the same script i run my app from
(thus using the same env vars i guess), and it clearly finds the
filesrc element. Am I overlooking something?

Before the filesrc output, gst-inspect prints:

anyone knows what that means?

It's not installed in the standard location.

What is the 'standard location?'

I have the same issue: 'no element xxxx' no matter what element I use.

But from the command line I can see all my elements with gst-inspect-0.10.

I also tried setting GST_PLUGIN_PATH env variable(and printed it out in my java app from System.getenv() to make sure its available)

but it still doesnt work?
