• 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
