Do you need to do it in Android? Why?

This is too broad topic. There are many ways to encode/transcode video and a good number of different formats/containers, compression algorithms and codecs.

I would highly recommend one of the most lean a capable products, opens-source ffmpeg:
http://en.wikipedia.org/wiki/Ffmpeg[^],
http://ffmpeg.org/[^].

See also related libavcodec:

http://libav.org/[^].

The product in both flavors is multiplatform and certainly available for Android as well. Please see:
http://sourceforge.net/projects/ffmpeg4android/[^].

Thank you.
(By the way, these days I'm transcoding some of my videos purchased years ago just to save them: the codecs are phased out from all bundles as obsolete, so I had to bite a bullet: installed a virtual PC, found very old codes and transcoded the video. Nothing worked better for me than ffmpeg. VideoLAN (also based on ffmpeg) can be used, too, but for pure transcoding ffmpeg is much better.)
