Hi everybody,

Me again. :)

This time I having a little issue with a pipeline getting video from
an RTSP source.

Here is the code:

import java.awt.BorderLayout;
import java.awt.Dimension;

import javax.swing.JFrame;
import javax.swing.SwingUtilities;

import org.gstreamer.Caps;
import org.gstreamer.Element;
import org.gstreamer.ElementFactory;
import org.gstreamer.Gst;
import org.gstreamer.Pipeline;
import org.gstreamer.State;
import org.gstreamer.swing.VideoComponent;

public class RTSPClient2 {

private static Pipeline pipe;
public static void main(String[] args) {

args = Gst.init("PipelineLauncher", args);
pipe = new Pipeline("VideoTest");

final Element videosrc =
ElementFactory.make("rtspsrc", "videoRTSPSource");
videosrc.set("location","rtsp://root:ro...@10.0.10.25/mpeg4/1/
media.amp");
videosrc.set("latency", 6000);

SwingUtilities.invokeLater(new Runnable() {

public void run() {
// Create the video component and link it in

VideoComponent videoComponent = new VideoComponent();
Element videosink = videoComponent.getElement();
pipe.addMany(videosrc, videosink);
Element.linkMany(videosrc, videosink);

// Now create a JFrame to display the video output
JFrame frame = new JFrame("Swing Video Test");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(videoComponent, BorderLayout.CENTER);
videoComponent.setPreferredSize(new Dimension(320, 240));
frame.pack();
frame.setVisible(true);

pipe.setState(State.PLAYING);
Gst.main();

// Start the pipeline processing
if(pipe.isPlaying())
System.out.println("Pipe is playing...");
else
System.out.println("Pipe is NOT playing...");
}
});

}
}

There are not compilation errors (may be is why a can't get a
solution), the issue is that a JFrame pop up with an empty black
screen! And video nevers shows up...

What I am missing?

Thanks one more time!

Yeipi

I think Gst.main() should not be called from here. Check with a debugger to see either your run() command ever returns.

Thanks Tal for your awnser!

I delete the Gst.main() line and nothing changes.

I made a debug and the run() method returns and I call the
Pipeline.isPlaying() method and returns true!

Maybe is something in the JFrame that is not initialized well?

Any help will be helpfull, I stumped with this...

Regards,
Yeipi

Needless asking: your exact pipeline works well from the command-line using autovideo sink as your display element (or the appropriate element for your platform)?

Yes Tal,

Here is the command:gst-launch-0.10.exe rtspsrc location=rtsp://
root:ro...@10.0.10.25:554/mpeg4/1/media.amp latency=0 ! decodebin !
ffmpegcolorspace ! autovideosink

And with this command I'm getting the stream and rendered to the
screen...

In console, I´m getting some deparsing packet errors, Following I´m
posting these errors, but I think that is not relationed to my
issue...

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...

Could you rebuild your Java application to create the pipeline using:

pipe = Pipeline.launch("rtspsrc location=rtsp://root:ro...@10.0.10.25:554/mpeg4/1/media.amp latency=0 ! decodebin ! ffmpegcolorspace name=f");

then do in the appropriate place in your code:
pipe.add(videosink);
pipe.getElementByName("f").link(videosink)
pipe.play()

Actually you don't need the ffmpegcolorspace element, but I think you need to place a decodebin between your rtspsrc and the videosink.

Tal you rule!

Last post solve my problem, just for the record I'm posting the final
code!

import java.awt.BorderLayout;
import java.awt.Dimension;

import javax.swing.JFrame;
import javax.swing.SwingUtilities;

import org.gstreamer.Caps;
import org.gstreamer.Element;
import org.gstreamer.ElementFactory;
import org.gstreamer.Gst;
import org.gstreamer.Pipeline;
import org.gstreamer.State;
import org.gstreamer.swing.VideoComponent;

public class RTSPClient2 {

private static Pipeline pipe;
public static void main(String[] args) {

args = Gst.init("PipelineLauncher", args);

final String def = "rtspsrc location=rtsp://root:ro...@10.0.10.25/

mpeg4/1/media.amp latency=0 ! decodebin ! ffmpegcolorspace

name=testp";
final Pipeline pipe = Pipeline.launch(def);
// final Element rtsp = pipe.getElementByName("src");
// rtsp.set("latency", 6000);

SwingUtilities.invokeLater(new Runnable() {

public void run() {
// Create the video component and link it in
VideoComponent videoComponent = new VideoComponent();
Element videosink = videoComponent.getElement();

pipe.add(videosink);
pipe.getElementByName("testp").link(videosink);
pipe.setState(State.PAUSED);

if(pipe.isPlaying())
System.out.println("Pipeline playing");
else
System.out.println("Pipeline not playing");

// Start the pipeline processing

pipe.play();
pipe.setState(State.PLAYING);

if(pipe.isPlaying())
System.out.println("Pipeline playing");
else
System.out.println("Pipeline not playing");

// Now create a JFrame to display the video output
JFrame frame = new JFrame("Swing Video Test");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(videoComponent, BorderLayout.CENTER);
videoComponent.setPreferredSize(new Dimension(320, 240));
frame.pack();
frame.setVisible(true);
}

});
Gst.main();
pipe.setState(State.NULL);
}
}

Thanks again!
