ffmpeg for a android (using tutorial: "ffmpeg and Android.mk")

Question

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.

STEP4: Configuring ...

STEP5: cd to your NDK root dir, type make TARGET_ARCH=arm APP=ffmpeg-org

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.

Answer 1

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: http://bambuser.com/opensource

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: https://github.com/guardianproject/android-ffmpeg .

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

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

I found a guide on ffmpeg on android here: http://rxwen.blogspot.com/2010/05/use-ffmpeg-to-setup-streaming-server-on.html

He explains in another post how he got to do native programming on android to install ffmpeg. Hope it helps.
