Compress video with ffmpeg4android library

I tried to follow ffmpeg4android library, and I get the problem when compressing the video, as the Log image below.

I use intent to transfer to Compressing Media class,

Intent intent = new Intent(this, CompressingMedia.class);
intent.putExtra("file_path", mLlItems.get(0).getPath());
startActivity(intent);

This is the class was transfered to :

public class CompressingMedia extends BaseWizard {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Intent intent = getIntent();

    Log.d(Prefs.TAG, "path " + intent.getExtras().getString("file_path"));
    // /storage/emulated/0/DCIM/Camera/VID_20140312_090612.mp4

    String command = "ffmpeg -y -i " + intent.getExtras().getString("file_path") + 
            " -strict experimental -s 320x240 -r 15 -aspect 3:4 -ab 12288 -vcodec mpeg4 -b 2097152 -sample_fmt s16 /sdcard/out.mp4";

    // if you want to change the default work location (/sdcard/videokit/) use the uncomment the below method.
    // It must be defined before calling the copyLicenseAndDemoFilesFromAssetsToSDIfNeeded method,
    // in order for this method to copy the assets to the correct location.
            //      setWorkingFolder("/sdcard/videokit/");

    // this will copy the license file and the demo video file.
    // to the videokit work folder location.
    // without the license file the library will not work.
    copyLicenseAndDemoFilesFromAssetsToSDIfNeeded();

    commandStr = command;
    setCommand(commandStr);

    runTranscoing();
    }
}

Although I received the notification Transcoding Successfully, but it looks like the capacity of file after compressing is always be 0. (the log in the bottom of images)

I don't know the result as image below is good or not, I can not get the expected result - The video was compressed totally successfully.

Someone know why after compressing the file is always be 0, please tell me. Thanks.

According to your log, the command you used is not correct. Its possible your video file does not correspond to the size, and aspect parameters you used.

See your log line here: 03-13 14:49:48.645: I/line(6065): _rate, rate, width or height

The best way is to post a link to the input video file so I can check it.

You may also consider using the real (and free!) FFmpeg for Android from the original source: http://trac.ffmpeg.org/wiki/How%20to%20compile%20FFmpeg%20for%20Android instead of using some third-party compilation from a guy who seems to violate FFmpeg LGPL license.
