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);
}and the logcat is
