Efficient and fast way to encode images to Video/GIF in Android

Question

I'm trying to make a video out of viewshots in an app. I have succeeeded to get the images as Bitmaps using this code.

    public Bitmap getScreenShot() {
    View screenView = findViewById(R.id.button);
    screenView.setDrawingCacheEnabled(true);
    Bitmap bitmap = Bitmap.createBitmap(screenView.getDrawingCache());
    screenView.setDrawingCacheEnabled(false);

    return bitmap;
    }

I have encode images using SequenceEncoder like this :

for(Bitmap bitmap : bitmaps)
    sequenceEncoder.encodeImage(bitmap);

I have got it working and got the file but it takes a lot of time. I have also tried to use MediaMuxer(I used EncodeDecode) but failed to even get a video, I have tried to make a GIF(using AnimatedGifEncoder) but a lot of time too. I want a way to make this video in a very short time.
