  • merge an audio and an image and create video using fmpeg android

    5 juin 2013, par Kamal Sharma

    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.

    I used the code :

    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);
    
}

    and the logcat is
