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.

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

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.
I found a guide on ffmpeg on android here:

He explains in another post how he got to do native programming on android to install ffmpeg. Hope it helps.
In NDK r3, when you use the make 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 android.mk somewhere within NDK/apps/ffmpeg-org/jni/
ReplyDeleteIn otherwords, ensure that your foldername is set to ffmpeg-org.
EDIT: You might find it worthwile to use NDK r4 which changes make to ndk-build. In this new NDK, you don't need to have your project set up in any particular way, as ndk-build simply searches your project for Android.mk files to tell it what to compile.
