Playing a video with JavaCV and FFmpeg

Question

So, I'm developing a custom video player for Android but I need to play more than the android supported video files (mp4, 3gp...), like wmv, avi, flv.

At this time I do already convert any video type to .mp4 and I'm able to play them after recoding, but I have no idea how can I play those wmv, avi files without recoding them to mp4 video formats.

Is there any way I can play any video on Android without recoding them? JavaCV + FFmpeg library already working, just don't know how to do that.

By the way, heres the code that I'm using to recode videos:

public static void convert(File file) {

    FFmpegFrameGrabber frameGrabber =
            new FFmpegFrameGrabber(file.getAbsolutePath());

    IplImage captured_frame = null;

    FrameRecorder recorder = null;
    recorder = new FFmpegFrameRecorder("/mnt/sdcard/external_sd/videosteste/primeiroteste.mp4", 300, 300);
    recorder.setVideoCodec(13);
    recorder.setFrameRate(30);
    recorder.setFormat("mp4");
    try {
        recorder.start();
        frameGrabber.start();
        while (true) {
            try {
                captured_frame = frameGrabber.grab();

                if (captured_frame == null) {
                    System.out.println("!!! Failed cvQueryFrame");
                    break;
                }
                recorder.record(captured_frame);
            } catch (Exception e) {
            }
        }
        recorder.stop();
        recorder.release();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

first you create the CanvasFrame then use "canvas.showImage(captured_frame);" instead of "recorder.record(captured_frame);"

Here is the code:

public class GrabberShow implements Runnable 
{
    final static int INTERVAL=40;///you may use interval
    IplImage image;
    static CanvasFrame canvas = new CanvasFrame("JavaCV player");


    public GrabberShow() 
   {
        canvas.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);
   }


    public static void convert(File file) 
    {

    FFmpegFrameGrabber frameGrabber = new FFmpegFrameGrabber(file.getAbsolutePath());

    IplImage captured_frame = null;

    FrameRecorder recorder = null;
    //recorder = new FFmpegFrameRecorder("/mnt/sdcard/external_sd/videosteste/primeiroteste.mp4", 300, 300);
    recorder = new FFmpegFrameRecorder("D://temp.mp4", 300, 300);
    recorder.setVideoCodec(13);
    recorder.setFrameRate(30);
    recorder.setFormat("mp4");
    try {
        recorder.start();
        frameGrabber.start();
        while (true) {
            try {
                captured_frame = frameGrabber.grab();

                if (captured_frame == null) {
                    System.out.println("!!! Failed cvQueryFrame");
                    break;
                }
                //recorder.record(captured_frame);
                canvas.showImage(captured_frame);
                Thread.sleep(INTERVAL);
            } catch (Exception e) {
            }
        }
        recorder.stop();
        recorder.release();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
@Override
public void run() 
{
    convert(new File("D://aes.mp4")); 
}

public static void main(String[] args) {
    GrabberShow gs = new GrabberShow();
    Thread th = new Thread(gs);
    th.start();
}
}
