• vmd : decode videos with no LZ buffer size provided - they might not need it

  vmd : decode videos with no LZ buffer size provided - they might not need it
  The buffer is used for an additional pass of frame compression, so videos
  
  can be coded without ever using it (and some are coded so indeed, e.g. in
  
  Woodruff and the Schnibble of Azimuth game).

• FFMPEG:Merging Audio(.mp3) and single image convert them into a Video

  5 juin 2013, par Nitish Singla

  I want to merge IMAGE + AUDIO and convert them into video using FFMPEG library,i compiled the library successfully,and got libfmpeg.so.but getting problem to execute the ffmpeg command through java code.This is command which i am using...
  "ffmpeg -i image8.jpg -i file.m4a -acodec copy test.mp4"
  if i execute this ffmpeg command through CMD,my video.mp4 file is successfully created,but if exceute same command through my Activity,it doesnot create any file.

  MY CODE IS :

  public class Mpeg extends Activity

  static {
  
  
  
      System.loadLibrary("ffmpeg");
  
  
  
  }
  
  
  
  @Override
  
  protected void onCreate(Bundle savedInstanceState) {
  
      super.onCreate(savedInstanceState);
  
      setContentView(R.layout.activity_mpeg);

  File mf = Environment.getExternalStorageDirectory() ;

      String livestream = mf.getAbsoluteFile()+"smile.png";
  
  
  
      String folderpth = mf.getAbsoluteFile()+"RABBA.MP3";
  
  
  
      //String output="/home/saicomputer/game.mp4";
  
  
  
      String output = new File(Environment.getExternalStorageDirectory(), "video.mp4").getAbsolutePath();
  
      Log.i("Test", "Let's set output to " + output);
  
  
  
      String cmd="ffmpeg -i "+ livestream +" -i "+ folderpth +" -acodec copy "+ output;
  
  
  
       Log.e("chck plzzzzz", "after "+ cmd);
  
  
  
      //String jaiho="ffmpeg -i image8.jpg -i file.m4a -acodec copy test.mp4";
  
  
  
      try{
  
  
  
      Process p = Runtime.getRuntime().exec(cmd);
  
  
  
      }
  
  catch(Exception e)
  
  {
  
      System.out.println("exception"+e);
  
  }
