Transcode/Convert Video to Mp4 on Android

Question

I've a requirement where I need to transcode small video clips shot from Native camera app to lower bitrate/resolution Mp4 which is shreable via email etc.

What is the best way to transcode/convert the video on device itself. FFMPEG or any other library?

p.s. I know this is an overkill for the device but client leaves me with no option. He doesn't care about battery or time it takes. I'm targeting this for quad-cores, where CPU is not a problem.

Your best bet would be to use something like ffmpeg which has been ported to Android (see this SO post: ffmpeg for a android (using tutorial: "ffmpeg and Android.mk") and the ffmpeg port for android which is here: http://bambuser.com/opensource). You'll have to use JNI etc, but that will save you the hassle of dealing with the byte stream yourself.
