KODI cuts my movie

Hello,

I would like you to help me with the video player issue.

The issue is that when I play my video on KODI default player (hardware is Raspberry PI 3) the video starts after about 2 seconds from the beginning of the video and ends before about 2 seconds from the ending of my video.

My video is encoded in HD 1080p using H.264 codec (50 frames per seond). Video is playing fine and smooth but the issue is about cutted 4 seconds from my video.

Do you have any idea how to solve it?

Thanks in advance!
