ffmpeg ndk multiple definition libavcodec.a(golomb.o) - c++

Question

I'm trying to link ffmpeg as static libraries with android NDK but I'm getting 'multiple definition' error' errors as below. I've also included my build script which runs through everything just fine but when I come to using the libraries in Eclipse with the ADT plugin, I can't get anywhere.
From this it looks like it wants something to do with VLC. I don't want anything to do with VLC, just ffmpeg for video streaming. Everything works fine with shared libraries, but I'm after a very tiny player because I'm restricted to space on the device.
EDIT: Also 'log2_tab_tab.o' has multiple definitions.

Using the latest branch of ffmpeg (2.4.3) my build script for Android (using toolchain 8 because it's old hardware I'm working with) and wanting the NEON hardware support:

And this is the Android.mk file which works fine.

include $(BUILD_SHARED_LIBRARY)
If anybody can spot what's wrong with this it would be so appreciated.

I figured it out by using a similar build method someone else used and just added my own options. This one also copies the folders "bin", "lib", "include" and the "share". All I needed then was to add the "lib" and "include" folders to my project. Phew!
