title: How to use android ndk r9b to compile FFMPEG for Android
body: <p>I want to design an Android app which can play and edit video by FFMPEG commands.
  But I don't know how to use FFMPEG on Android. I have tried many methods searched from Google, but they are too old to implement.
  Now, the newest version of FFMPEG is 2.1.1 and the Android-NDK's version is r9b. My operating system is Linux mint 15.
  How can I use eclipse IDE on my OS to implement an Android app which has FFMPEG's newest decoder and encoder?</p>
