  I have successfully compiled the FFMPEG library to android using NDK.
  (using Rock Player FFMPEG implementation)http://www.rockplayer.com/download/rockplayer_ffmpeg_git_20100418.zip

  I know that FFMPEG supports .avi, divX, mov ect. But I created a mediaplayer and tried to run them but I was not able to play them. I is this the right way to use the FFMPEG library. Can Any one Help.I am able to play defaut video, mp4, 3gp etc. Here is the code for mediaplayer

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

• FFMPEG - Correct command line parameters to create a H.264 Streaming MP4 from a set of images

  5 janvier 2012, par Adam

  I have no problems viewing a video created by my current parameters in a HTML5 browser, Flash player, Windows Phone 7, Android Phone, etc. However, they won't display on iPhone or iPad. If I modify the video using Super and select "Enable Streaming" checkbox they work on iPhone and iPad suddenly. We are suspecting that my command line parameters are incorrect for enabling h.264 streaming and are instead generating a "progressive download" video.

  I'm pretty new to FFMPEG and don't understand a lot of the parameters. Can anyone help correct my existing parameters, or maybe provide the missing parameters, etc ?

  Thanks in advance.

  My current FFMPEG command line paramters are :

  ffmpeg.exe 
   -r 30 
   -threads 4 
   -f image2 
   -i .\frame%05d.jpg 
   -i audioFile  
   -acodec aac 
   -ab 128k 
   -ar 44100
   -vcodec h264 
   -crf 27 
   -coder 1 
   -flags +loop 
   -cmp +chroma 
   -partitions +parti4x4+partp8x8+partb8x8 
   -me hex 
   -subq 5 
   -me_range 16 
   -g 60 
   -keyint_min 25 
   -sc_threshold 40 
   -i_qfactor 0.71 
   -b_strategy 1 
   out.mp4
