I am trying to utilise RTMPGW as part of my app, which usually works great in Linux. I am trying to use the Vitamio bundle to play back the stream. Here is the main code, taken from the Vitamio Demo:
package io.vov.vitamio.demo;
import io.vov.vitamio.MediaPlayer;
import io.vov.vitamio.widget.MediaController;
import io.vov.vitamio.widget.VideoView;
import android.app.Activity;
import android.content.res.Configuration;
import android.net.Uri;
import android.os.Bundle;
public class VideoViewDemo extends Activity {
private VideoView mVideoView;
/* (non-Javadoc)
* #see android.app.Activity#onCreate(android.os.Bundle)
*/
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
if (!io.vov.vitamio.LibsChecker.checkVitamioLibs(this))
return;
setContentView(R.layout.videoview);
mVideoView = (VideoView) findViewById(R.id.surface_view);
mVideoView.setVideoURI(Uri.parse("http://172.16.1.182:8902/?r=rtmp://live.dtv.cubecdn.net:80/kdmobil/KanalD1&W=http://www.kanald.com.tr/Content/swf/Canliplayer6.swf?config=/Content/swf/Config.xml%26debug=false&p=http://www.kanald.com.tr&c=80"));
mVideoView.setVideoQuality(MediaPlayer.VIDEOQUALITY_HIGH);
mVideoView.setMediaController(new MediaController(this));
mVideoView.requestFocus();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
if (mVideoView != null)
mVideoView.setVideoLayout(VideoView.VIDEO_LAYOUT_SCALE, 0);
super.onConfigurationChanged(newConfig);
}
}
When I run this, RTMPGW (which I am running from the terminal in Linux) displays this error:
processTCPrequest, Range request not supported
..and sits there idly, doing nothing.
However, when I use regular Android VideoView with this code (in a different project):
package com.sample.videoviewexample;
import android.app.Activity;
import android.net.Uri;
import android.os.Bundle;
import android.widget.MediaController;
import android.widget.VideoView;
public class MainActivity extends Activity {
private VideoView mVideoView;
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.activity_main);
mVideoView = (VideoView) findViewById(R.id.surface_view);
mVideoView.setVideoURI(Uri.parse("http://172.16.1.182:8902/?r=rtmp://live.dtv.cubecdn.net:80/kdmobil/KanalD1&W=http://www.kanald.com.tr/Content/swf/Canliplayer6.swf?config=/Content/swf/Config.xml%26debug=false&p=http://www.kanald.com.tr&c=80"));
mVideoView.setMediaController(new MediaController(this));
mVideoView.requestFocus();
}
}
It connects to the RTMPGW server and starts streaming like so...
Streaming on http://0.0.0.0:8902
processTCPrequest, Range request not supported
Connecting ... port: 80, app: kdmobil/KanalD1
1094.914 KB / 16.90 sec
But, of course, as Android MediaPlayer doesn't support Flash natively it won't play back the video.
Why does the VideoView connect with RTMPGW's server but Vitamio doesn't?
Thanks for your help,
Dan

Everytime i try to show the results from the page, it downloads the results in json format instead of showing them on page.
It starts to download when i enter the url where the objects/information is stored, instead of showing the page http://localhost:8082/spring-rest-demo/api/students
If i run the server and paste this info in postman og google chrome, it does show the correct information without downloading it as a json file.
this is how it should be
Thank you

}
Try to add produces application/json in #GetMapping annotation.
This is a bug in recent versions of Eclipse. Hopefully the Eclipse team will fix it soon
I am trying to send json object through volley in android studio to a server (mvc spring project in eclipse + tomcat is listening) but the app crashes. I'm new to the volley library. Also, the json object is made up of the data gotten from user inputs in combo box and textviews.

I am using chrriis.dj.nativeswing.swtimpl.components.JWebBrowser in my swing application to open web page of a jupyter-notebook. Now my problem is when I click New->Python 3 button JWebBrowser to new a file, it always return the 404 page.

Thanks Thomas K. I changed the engine of jwebbrowser to Xulrunner-24.0.en-US and the problem disappeared.
I am trying to start with a simple web service following the example : https://spring.io/guides/gs/rest-service/
I am unable to get any response when I hit the service URL. The way I am trying to run this is by running the project on Apache web server from Eclipse.
This is my controller:
package com.nscm.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.nscm.model.User;
#RestController
public class NSCMController {
#RequestMapping("/getuser")
public User getUser()
{
System.out.println("NSCMController.getUser()");
return new User();
}
}
This is my service class:
package com.nscm.service;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.context.annotation.ComponentScan;
#ComponentScan("com")
#EnableAutoConfiguration
public class Application {
public static void main(String[] args) {
System.out.println("Application.main()");
SpringApplication.run(Application.class, args);
}
}
Even though as the example mentions the web.xml and the spring.xml is not required, even after placing these, my code does not work. None of the SOPs are called when I hit the URL. Please help me if I am missing anything here.
I am using javafx webview to load a local html page in a jpanel. Executing the code gives me following message:
Outstanding resource locks detected: D3D Vram Pool: 13,810,710 used (5.1%), 13,810,710 managed (5.1%), 268,435,456 total
14 total resources being managed
average resource age is 0.8 frames
0 resources at maximum supported age (0.000000)
3 resources marked permanent (21.400000)
3 resources have had mismatched locks (21.400000)
3 resources locked (21.400000)
5 resources contain interesting data (35.700000)
I am new to java and I don't understand why this message is being generated and how it could be resolved (my html page works fine and so does the swing code - gives me the desired result).I tried looking it up online but was unable to find a solution.
Please let me know if any other information is needed.
Edit:
I'm trying to develop a video annotation tool. The tags to be attached to the video and their handling is all done in java swing. The video itself is a part of the html page I'm loading in a javafx webview. I've placed a semi-transparent canvas on it which I'm using to register mouse-click events to attach the tags to specific content on the video at a certain time. Below the video tag is another canvas which acts as the timeline (shows attached tags at the appropriate time). That's the basic goal for the code.
Here's the code where I add my jfxpanel:
package codingAnnotations;
import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;
import javafx.application.Platform;
import javafx.embed.swing.JFXPanel;
import javafx.event.EventHandler;

#SuppressWarnings("serial")
public class JFXContainerPanel extends JPanel {
private final JFXPanel WebViewContainer;
private final JFXPanel TimeLineContainer;
public JFXContainerPanel(){
WebViewContainer = new JFXPanel();
TimeLineContainer = new JFXPanel();
add(WebViewContainer);
Platform.runLater(new Runnable() {
#Override
public void run() {
initFX(WebViewContainer);
}
});
}
private static void initFX(final JFXPanel fxPanel) {
Group group = new Group();
Scene scene = new Scene(group);
WebView webView = new WebView();
group.getChildren().add(webView);
webView.setMinSize(500, 500);
webView.setMaxSize(800, 600);
final String html = "res/VideoCanvas.html";
final java.net.URI uri = java.nio.file.Paths.get(html).toAbsolutePath().toUri();
System.out.println(uri.toString());
WebEngine webEngine = webView.getEngine();
webEngine.load(uri.toString());
webEngine.setOnAlert(new EventHandler<WebEvent<String>>(){
#Override
public void handle(WebEvent<String> arg0) {
String value = arg0.toString().substring(10, arg0.toString().length() - 1);
System.out.println(value);
}
});
fxPanel.setScene(scene);
}
}
Thanks for your help!
