Seekbar doesn't work with Trimtype.MIN_MAX_DURATION

[hsinha76]

                        TrimVideo.activity(String.valueOf(data.getData()))
                                .setTrimType(TrimType.MIN_MAX_DURATION)
                                .setMinToMax(0, 30)
                                .start(this, videoTrimResultLauncher);

Using the above code but in this case I'm not able to move the seekbar. Suppose the video is of 50 seconds the seekbar covers the whole video.
