     public native String  stringFromJNI();
  
        static {
  
           System.loadLibrary("ffmpeg");
  
           System.loadLibrary("ffmpeg-test-jni");
  
               }
  
      @Override
  
        public void onCreate(Bundle savedInstanceState) {
  
        super.onCreate(savedInstanceState);
  
  
  
  
  
      setContentView(R.layout.main);
  
  
  
      TextView  tv =(TextView) findViewById(R.id.textView1);
  
      tv.setText( stringFromJNI() );

      Log.d("Video FFmpeg ", "**");
  
  
  
      getWindow().setFormat(PixelFormat.TRANSLUCENT);
  
      String filepath = Environment.getExternalStorageDirectory()+"/simple.avi";

• Flv video time is shorter than normal when using flv segment in osmf

  7 janvier 2013, par David

  I am working on a project to use flv segments rather than a normal video clip. We use ffmpeg to split a mp4 file into several flv files with headers. The duration of each flv file is 5 second with 15 fps. Given a 10 minutes of video file, after split it, the osmf player only indicates 9:53 as timescale after all content played.

  The code is very simple, after download each flv segment, we use appendBytesAction(NetStreamAppendBytesAction.RESET_BEGIN) and appendBytes() to join all segments.

  Can anyone help me out ? Thanks a lot.
