How to play video from a specific position?

I'm wanting to create a program that you can play an AVI file startin开发者_开发问答g at a specific position, and to play for a specified amount of time. I can't figure out how to start at a specific position. Anybody know what I should do? Thanks.

I assume that you are using MediaPlayer class to play the movie. You can start movie from a specific position by setting current position property. Here is the documentation of "position" property,
