• Error with ffmpeg in android (java.lang.UnsatisfiedLinkError)

  12 janvier 2015, par Hussnain Muavia

  I am facing this java.lang.UnsatisfiedLinkError in android. While i have also androidndk and other essential parts required for running ffmpeg in android like jni folder files ffmped, armeabi, build_ files etc. I have figured it out a lot of time but its not fixed yet. Please guide me about my problem.
  This is my basic code

  public class MainActivity extends Activity {
  
  
  
  static {
  
      System.loadLibrary("ffmpeg");
  
     System.loadLibrary("ffmpeg-test-jni");
  
  }
  
  TextView text_titlebar_text;
  
  
  
  @Override
  
  protected void onCreate(Bundle savedInstanceState) {
  
      super.onCreate(savedInstanceState);
  
      setContentView(R.layout.activity_main);
  
  
  
        text_titlebar_text = (TextView) findViewById(R.id.tvView);
  
  
  
          showVideoInfo(new File(Environment.getExternalStorageDirectory().getAbsoluteFile()+ "/video.mp4"));
  
  }
  
  
  
  //declare the jni functions
  
  private static native void naInit(String _videoFileName);
  
  private static native int[] naGetVideoResolution();
  
  private static native String naGetVideoCodecName();
  
  private static native String naGetVideoFormatName();
  
  private static native void naClose();
  
  
  
  private void showVideoInfo(final File _file) {
  
     String videoFilename = _file.getAbsolutePath();
  
     naInit(videoFilename);
  
     int[] prVideoRes = naGetVideoResolution();
  
      String prVideoCodecName = naGetVideoCodecName();
  
      String prVideoFormatName = naGetVideoFormatName();
  
      naClose();
  
      String displayText = "Video: " + videoFilename + "\n";
  
      displayText += "Video Resolution: " + prVideoRes[0] + "x" + prVideoRes[1] + "\n";
  
      displayText += "Video Codec: " + prVideoCodecName + "\n";
  
      displayText += "Video Format: " + prVideoFormatName + "\n";
  
      text_titlebar_text.setText(displayText);
  
  
  
  
  
  }

  }

  and this is a LogCat

• How to stream a usb webcam to an android phone with ffmpeg and ffserver ?

  26 juillet 2015, par victor jung

  I am desperately trying to live stream the usb webcam from a linux computer to my android phone.
  I tried with ffmpeg and ffserver, to create the stream and with videoview in android to display it. I tried all the possible format/encoder/protocols possibilities but nothing worked. In most case I am able to open the stream in VLC in another PC, but I was never able to play on my phone. I always get this error :
  "can’t play this video"
  Here is my app code :

  package com.example.victor.videostream;
  
  import android.os.Bundle;
  
  import android.app.Activity;
  
  import android.view.View;
  
  import android.net.Uri;
  
  import android.widget.MediaController;
  
  import android.widget.VideoView;
  
  public class MainActivity extends Activity
  
   {
  
  VideoView videoView;
  
  @Override
  
   protected void onCreate(Bundle savedInstanceState)
  
  {
  
       super.onCreate(savedInstanceState);
  
       videoView = null;
  
       setContentView(R.layout.activity_main);
  
  
  
       videoView =(VideoView)findViewById(R.id.VideoView);
  
       MediaController mediaController= new MediaController(this);
  
       mediaController.setAnchorView(videoView);
  
  
  
   Uri uri = Uri.parse("http://host:port/mystream.3gp");
  
    videoView.setMediaController(mediaController);
  
    videoView.setVideoURI(uri);
  
    videoView.requestFocus();
  
    videoView.start();
  
         }
  
          }

  I read here

  about god encoding practice for android, but even with .3gp format encoded with mpeg4 as suggested it doesn’t work. Have any body once succeeded doing this ?
  I am also up to discover other possibilities to stream this webcam to my android if you have any ideas.
  this is the closest post I found but no solution...
  Hope somebody can help !
  thanks for reading.
