Using OpenGL video output with glimagesink
dvrslype
I installed the gstreamer OpenGL plugin on my Ubuntu system
(http://packages.ubuntu.com/dapper/i386/gstreamer0.10-gl/download)
This offers the glimagesink output module, but I can't seem to use it
with gstreamer-java:
Exception in thread "AWT-EventQueue-0"
java.lang.IllegalArgumentException: Element does not implement
interface
at org.gstreamer.interfaces.GstInterface.<init>(GstInterface.java:43)
at org.gstreamer.interfaces.XOverlay.<init>(XOverlay.java:55)
at org.gstreamer.interfaces.XOverlay.wrap(XOverlay.java:46)
at videotest.Main$1.run(Main.java:50)
What do I need to do to get this to work? Are there some bindings that
need to be added to gstreamer-java?

overlay currently support swing, awt and swing.
we haven't use opengl yet:-(
but patches are welcome:-)

====================== very slightly modified OverlayPlayer.main() ===================
public static void main(String[] args) {
//System.setProperty("sun.java2d.opengl", "True");
args = Gst.init("Swing Player", args);
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("videtestsrc ! glimagesink name=gl");
bus = player.getBus();
bus.connect(new Bus.ERROR() {
public void errorMessage(GstObject source, int code, String message) {
System.out.println("Error: code=" + code + " message=" + message);
}
});
final Element videoSink = player.getElementByName("gl");
//
// Setting the overlay window ID is supposed to be done from a sync handler
// but that doesn't work on windows
//
if (!Platform.isWindows()) {
bus.setSyncHandler(new BusSyncHandler() {
public BusSyncReply syncMessage(Message msg) {
Structure s = msg.getStructure();
if (s == null || !s.hasName("prepare-xwindow-id")) {
return BusSyncReply.PASS;
}
XOverlay.wrap(videoSink).setWindowID(canvas);
return BusSyncReply.DROP;
}
});
} else {
XOverlay.wrap(videoSink).setWindowID(canvas);
}
player.play();
}
});
}
================================================================

do this "!Platform.isWindows()" really needs?
do you test it with gstreamer-java head?

Thanks for your support.

Farkas Levente
should have to be working on all platforms...
Farkas Levente
in the comment and bellow you wrote setSyncHandle have to use on
windwos, but in the code use:
if (!Platform.isWindows())
so what's the current situation?

that's why i don't understand it.
tomorrow i'll test it in windows...
