にIOExceptionがAndroidの

上の透かしビデオに私は、プログラムのGithubからWritingMinds' ffmpegのライブラリを使用してAndroidのビデオを透かししようとしています：にIOExceptionがAndroidの

https://github.com/WritingMinds/ffmpeg-android-java

私は、彼らが自分のドキュメントに言ったすべてをしたとAndroidでライブラリをインポートスタジオ。

それでも、「No such file or directory」というIOExeptionが表示されます。

CODE

public class MainActivity extends Activity { 

Button btn; 
Context context; 

String str; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.activity_main); 

btn = (Button) findViewById(R.id.button); 

context = this; 

str = "ffmpeg -i /storage/extSdCard/DCIM/Camera/video.avi -i /storage/extSdCard/DCIM/Camera/logo.png -filter_complex 'overlay=10:main_h overlay_h-10' /storage/extSdCard/DCIM/Camera/watermarked.avi"; 

btn.setOnClickListener(new View.OnClickListener() { 
@Override 
public void onClick(View view) { 

doFfmpeg(str.split(" ")); 

    } 
    }); 
} 
} 

public void doFfmpeg(String[] loc){ 

FFmpeg ffmpeg = FFmpeg.getInstance(context); 

try { 
// to execute "ffmpeg -version" command you just need to pass "-version" 
ffmpeg.execute(loc, new ExecuteBinaryResponseHandler() { 

@Override 
public void onStart() { 
} 

@Override 
public void onProgress(String message) { 
} 

@Override 
public void onFailure(String message) { 
} 

@Override 
public void onSuccess(String message) { 

Toast.makeText(getApplicationContext(), "Success !", Toast.LENGTH_LONG).show(); 

} 

@Override 
public void onFinish() { 
    } 
}); 
} catch (FFmpegCommandAlreadyRunningException e) { 
// Handle if FFmpeg is already running 
} catch (Exception e){ 

} 

} 
}
