Answer 1

I have no such idea about ffmpeg but i can tell you about jCodec lib which is easy to use.

visit jcodec.org.

if you want to crop the video you will have to do below step in android or java. 1. get the frame from utility method from jcodec. 2. crop using Bitmap helper class. 3. pack in the mp4 format using jcodec utilty function.

if you are not able to do this kindly write a mail to me [email protected]

I will help to make the crop video application for you in android.

Thank you
