In NDK r3, when you use the <code>make</code> command, the NDK will simply use the name of the folder in the "apps" folder for the name of your project. This assumes that you have your FFmpeg source files and <code>android.mk</code> somewhere within <code>NDK/apps/ffmpeg-org/jni/</code>

In otherwords, ensure that your foldername is set to <code>ffmpeg-org</code>.

EDIT: You might find it worthwile to use NDK r4 which changes <code>make</code> to <code>ndk-build</code>. In this new NDK, you don't need to have your project set up in any particular way, as <code>ndk-build</code> simply searches your project for <code>Android.mk</code> files to tell it what to compile.

After looking around the net. The only working solution I found is supplied by Bambuser which ported ffmpeg to use in their android application.

Code is here: <a href="http://bambuser.com/opensource" rel="noreferrer">http://bambuser.com/opensource</a>

Basically you copy the .so files to your jni/lib directory, along with any .h files you might need, create a JNI wrapper through javah, and it works.

EDIT:

Since this post was written a few packaged ffmpeg projects for android surfaced, one of the easiest ones to compile and use is here: <a href="https://github.com/guardianproject/android-ffmpeg" rel="noreferrer">https://github.com/guardianproject/android-ffmpeg</a> . 

It takes the approach of statically compiling a binary (not a library) that is ran through shell command in run time. Search github for '<code>android ffmpeg</code>' for forks and related projects.

Did not find a well packaged method based JNI implementation, though.

I am trying to compile ffmpeg for a android. I have found several posts on this theme but non of these seems to work. If tried to build ffmpeg like it is posted on [1]. Did anybody successfully compile ffmpeg using theses tutorial?
I am not sure how to realize step 4 to 5.

<blockquote>
 STEP4: Configuring ...
 
 STEP5: cd to your NDK root dir, type make TARGET_ARCH=arm APP=ffmpeg-org
</blockquote>

It seems to me that building an application like it is explained in the tutorial in step 5 need some previous steps. Unfortunately I have no app in the folder to make. I am using the current android ndk release 3 and checked out the actual ffmpeg releases from [3] and [4]. I am thankful for every advice.
