Hi to all, 
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 compiled 
ffmpeg using theses tutorial? 

I am not sure how to realise 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 prevoius steps. Unfortunaly I have no 
app in the foulder 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. 

best regards Matthias

Actually, I think I have successfuly compiled FFMpeg (with an other 
process) but the generated ".a" files are really too heavy to be put 
in an app... 

If you know how to use such ".a" files, contact me in private, I will 
send you mine. (I really would like to understand how I can use such 
files)...

Those are archives, or more qualified in this case: They're static 
libraries. They contain each and every function. When you link 
applications agains them, the footprint may reduce drastically when only 
a subset of the libraries' functions is used.

@Hans-Werner Hilse : 
Thank you for your answer... But one more (stupid) question : How 
should I link the component I'm building (with the NDK) with those 
static libraries ? 

Thanks for you help.

Which method did you use to build ffmpeg successfully? (Or can you let 
me know what the problem was that you were having before when you 
couldn't build it?) 

Does anyone know of an ARM-optimised (free) implementation of an MPEG4/ 
HEAC decoder?
