How do I use Android OpenCORE codecs using JNI?

I want to use the codecs in Android from my application. For now I just want to use the H.264 codec for testing, unless the mp3 or aac codecs provide functions for sending the audio to the device's speaker in which case I would prefer one of those.

I have the NDK installed along with Cygwin, GNU Make, and GNU Awk. I can't figure out what I need to do from here though. I'm downloading the entire OpenCORE tree right now but I don't even know how to build it or make Eclipse plugin know it needs to include the files.

An example or a tutorial would be much appreciated.

EDIT:

It looks like I can use JNI like P/Invoke which would mean I don't have to build the OpenCORE libraries myself. However, I can't find any documentation on the names of the libraries I need to load.

I'm also confused as to how to do it. I'm looking at http://www.koushikdutta.com/2009/01/jni-in-android-and-foreword-of-why-jni.html and I don't understand what the purpose of writing a library to access a library is. Couldn't you just use something like System.loadLibrary("opencore.so")?

You cannot build opencore seperately. It has to be built with whole source code. What are you trying to acheive. If you just want to play a video/audio, use VideoView or MediaPlayer object.

Build the Android source and use the headers and the static library from it. This will propel you straight to the zone of unsupported APIs.
