Hello all :)
I tried GstRenderer and it work great, I have my JavaFX launched and in center I have videotestsrc.
But when I change the Bin.launch to set my pipeline, it launch and disapear in background and the state of Gst is pending, the Stage is showing up with a center white square.
This is the code I used :
import java.nio.ByteOrder;import org.freedesktop.gstreamer.Bin;import org.freedesktop.gstreamer.Bus;import org.freedesktop.gstreamer.Caps;import org.freedesktop.gstreamer.Gst;import org.freedesktop.gstreamer.Message;import org.freedesktop.gstreamer.Pipeline;import org.freedesktop.gstreamer.elements.AppSink;import javafx.application.Application;import javafx.application.Platform;import javafx.beans.value.ChangeListener;import javafx.beans.value.ObservableValue;import javafx.scene.Scene;import javafx.scene.image.Image;import javafx.scene.image.ImageView;import javafx.scene.layout.BorderPane;import javafx.stage.Stage;/** The main idea is to create a pipeline that has an appsink to display the images.* Connect the AppSink to the rest of the pipeline.* Connect the AppSinkListener to the AppSink.* The AppSink writes frames to the ImageContainer.* if you want to display the Videoframes simply add a changeListener to the container who will draw the current* Image to a Canvas or ImageView.*/public class GstRenderer extends Application{private ImageView imageView;private AppSink videosink;private Pipeline pipe;private Bin bin;Bus bus;private StringBuilder caps;private ImageContainer imageContainer;public GstRenderer() {videosink = new AppSink("GstVideoComponent");videosink.set("emit-signals", true);AppSinkListener GstListener = new AppSinkListener();videosink.connect(GstListener);caps = new StringBuilder("video/x-raw, ");// JNA creates ByteBuffer using native byte order, set masks according to that.if (ByteOrder.nativeOrder() == ByteOrder.LITTLE_ENDIAN) {caps.append("format=BGRx");} else {caps.append("format=xRGB");}videosink.setCaps(new Caps(caps.toString()));videosink.set("max-buffers", 5000);videosink.set("drop", true);bin = Bin.launch("playbin3 uri=\"https://r3---sn-25ge7nse.googlevideo.com/videoplayback?sparams=dur%2Cei%2Cid%2Cinitcwndbps%2Cip%2Cipbits%2Citag%2Clmt%2Cmime%2Cmm%2Cmn%2Cms%2Cmv%2Cpl%2Cratebypass%2Crequiressl%2Csource%2Cexpire&c=WEB&requiressl=yes&expire=1527779448&key=yt6&signature=2BDEF620EDFF94D801B905BBC8F75E5A34169F4C.53472FA6E280CD27D98AB3C7ABCAC57A55B5C2A9&mt=1527757724&ipbits=0&mm=31%2C29&mn=sn-25ge7nse%2Csn-25glenes&id=o-ANj_JLdEBZzyUBseDM3FjPVfrzalRzv8Rd5nLc_9XH74&ratebypass=yes&initcwndbps=2305000&mime=video%2Fmp4&ip=146.255.173.20&lmt=1524432032437132&dur=365.807&pl=21&itag=22&source=youtube&mv=m&ei=F7wPW7KcPK2mV5S4udAN&ms=au%2Crdu&fvip=3\"", true);pipe = new Pipeline();pipe.addMany(bin, videosink);Pipeline.linkMany(bin, videosink);imageView = new ImageView();imageContainer = GstListener.getImageContainer();imageContainer.addListener(new ChangeListener<Image>() {@Overridepublic void changed(ObservableValue<? extends Image> observable, Image oldValue, finalImage newValue) {Platform.runLater(new Runnable() {@Overridepublic void run() {imageView.setImage(newValue);}});}});bus = pipe.getBus();bus.connect(new Bus.MESSAGE() {@Overridepublic void busMessage(Bus arg0, Message arg1) {System.out.println(arg1.getStructure());}});pipe.play();}@Overridepublic void start(Stage primaryStage) throws Exception {primaryStage.setTitle("Drawing Operations Test");BorderPane grid = new BorderPane();grid.setCenter(imageView);imageView.fitWidthProperty().bind(grid.widthProperty());imageView.fitHeightProperty().bind(grid.heightProperty());imageView.setPreserveRatio(true);primaryStage.setScene(new Scene(grid, 460, 460));primaryStage.show();}public static void main(String[] args) {Gst.init("CameraTest",args);launch(args);}}
Even if I try with :
bin = Bin.launch("videotestsrc ! omxh264enc ! h264parse ! omxh264dec ! glimagesink", true);
I have the same result..
This is the stack trace for the first Bin.launch :

This is not how you would use a PlayBin - that is already a pipeline and you need to set the video-sink property on it. eg. this works with Swing (I don't have PlayBin 3 here) using the element factory directly rather than the PlayBin wrapper
```
Gst.init("MediaTest", args);
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
SimpleVideoComponent vc = new SimpleVideoComponent();
Element playbin = ElementFactory.make("playbin", "playbin");
playbin.set("uri", URI.create("file:///home/<PATH>"));
playbin.set("video-sink", vc.getElement());
JFrame f = new JFrame("Camera Test");
f.add(vc);
vc.setPreferredSize(new Dimension(640, 480));
f.pack();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
playbin.play();
f.setVisible(true);
}
});
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
SimpleVideoComponent vc = new SimpleVideoComponent();
Element playbin = ElementFactory.make("playbin", "playbin");
playbin.set("uri", URI.create("file:///home/<PATH>"));
playbin.set("video-sink", vc.getElement());
JFrame f = new JFrame("Camera Test");
f.add(vc);
vc.setPreferredSize(new Dimension(640, 480));
f.pack();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
playbin.play();
f.setVisible(true);
}
});
```
Likewise, to try your gl sink pipeline you should use Pipeline.launch() not Bin.launch() - these are different things!

I tried to launch with Pipeline.launch and the result is the same.
Maybe I'm doing something wrong ?

You can't do Pipeline launch with the glimagesink and try and add the other videosink in the same pipeline!

Ok I understand.
Can the Pipeline.launch be added to the imageView like the Bin.launch ?
How can I link the pipe to GstListener ?
This is the code I changed, same result :
//videosink.connect(GstListener);
caps = new StringBuilder("video/x-raw, ");// JNA creates ByteBuffer using native byte order, set masks according to that.if (ByteOrder.nativeOrder() == ByteOrder.LITTLE_ENDIAN) {caps.append("format=BGRx");} else {caps.append("format=xRGB");}
//videosink.setCaps(new Caps(caps.toString()));//videosink.set("max-buffers", 5000);//videosink.set("drop", true);
//bin = Bin.launch("videotestsrc ! omxh264enc ! h264parse ! omxh264dec ! glimagesink", true);pipe = Pipeline.launch("videotestsrc ! omxh264enc ! h264parse ! omxh264dec ! glimagesink");//pipe.addMany(bin, videosink);
//Pipeline.linkMany(pipe);

You can either have the AppSink or the glimagesink, not both!
You might be able to do something like
```
pipe = Pipeline.launch("videotestsrc ! omxh264enc ! h264parse ! omxh264dec name=decoder");
pipe.add(videosink);
pipe.getElementByName("decoder").link(videosink);
```
No idea if this will work - depends what formats the decoder can output and whether they match the caps on your appsink.

I changed the caps to :
caps = new StringBuilder("video/x-h264, ");Because the omxh264dec can only decode h264 according to gst-inspect
Now the following error appear :

What caps? You probably need to set the appsink caps based on the output of the decoder, not the input. I would take this on to the GStreamer devel list and see if you can get some input from one of the GStreamer devs - I'm stabbing in the dark without knowing enough about the omx stuff.
You could try putting a videoconvert after the decoder and link the appsrc to that rather than the decoder. If that works it's likely to be slow though. The problem you'll have is getting anything into JavaFX is not as performant as it could be!

I don't know what caps I need to set up, but this is the stack trace of gst-launch when I use glimagesink at the output of the pipeline :

And neither do I! ;-) That's why I'm suggesting taking this onto the GStreamer devel list, because I don't know what that element is capable of outputting.
It does look like it's outputting GLMemory in that trace. If that's all it's capable of, then you might have some difficulty getting this into JavaFX.

I understand.. Yes omxh264 seem to be based on OpenGL and I know that JavaFX is not OpenGL based..
I'm disapointed, I don't know if it's possible to redirect OpenGL render to JavaFX node or something like this

Actually, JavaFX on Pi almost certainly is OpenGL, just no easy way to access what's required.
With Swing it's possible to embed an AWT Canvas and render to (above) that with the native video sink and video overlay API I think - not actually tried this with the GStreamer 1.x bindings yet - it's on my roadmap to check.
JavaFX is too much of a black box. Hopefully that may change now it's not part of the JDK. But, if it wasn't obvious, I hate JavaFX - think it's the complete opposite of what we actually need - an AWT 2 with access to modern desktop integration.
