I have an `*.mp4` file which is duration of 2 min. Now it has audio track starting from `30 seconds upto 1.10 min`. The rest before `30s` and after `1.10min` is blank.

Now the problem is when I try to play it in `videoview` or `mediaplayer` then, it plays audio right from beginning of the video rather from its actual position. I tried this on multiple phones with same result.

When I play the same video in `MXPlayer` or in `Windows(VLC)`; it plays properly. 

What is the solution to this problem ?

**Edit**

I have used `-itsoffset` command of `Ffmpeg` for achieving above video.

```
ffmpeg -y -i a.mp4 -itsoffset 00:00:30 sng.m4a -map 0:0 -map 1:0 -c:v copy -preset ultrafast out.mp4

```

Thanks in advance.
