Usage

    new Mp4Composer(srcMp4Path, destMp4Path)
            .rotation(Rotation.ROTATION_90)
            .size((width) 540, (height) 960)
            .fillMode(FillMode.PRESERVE_ASPECT_FIT)
            .filter(new GlSepiaFilter())
            .listener(new Mp4Composer.Listener() {
                @Override
                public void onProgress(double progress) {
                    Log.d(TAG, "onProgress = " + progress);
                }

                @Override
                public void onCompleted() {
                    Log.d(TAG, "onCompleted()");
                    runOnUiThread(() -> {
                        Toast.makeText(context, "codec complete path =" + destPath, Toast.LENGTH_SHORT).show();
                    });
                }

                @Override
