This is a updated post for a previous post, where we built ffmpeg 0.8 with Android NDK r5 and r6. This post will give instructions of how to build ffmpeg 2.0.1 with Android NDK r9.

0. Download Android NDK

The latest version of Android NDK can be downloaded at Android NDK website. At the time of writing, the newest version is NDK r9. Note that the website provides both current and legacy toolchains. We only need the current toolchain to compile ffmpeg.

After download NDK, simply decompress the archive. Note that we’ll use $NDK to represent the root path of the decompressed NDK.

1. Download ffmpeg source code

FFMPEG source code can be downloaded from the ffmpeg website. The latest stable release is 2.0.1. Download the source code and decompress it to $NDK/sources folder. We’ll discuss about the reason for doing this later.

2. Update configure file

Open ffmpeg-2.0.1/configure file with a text editor, and locate the following lines.





This cause ffmpeg shared libraries to be compiled to<version> (e.g., which is not compatible with Android build system. Therefore we’ll need to replace the above lines with the following lines.





3. Build ffmpeg

Copy the following text to a text editor and save it as





function build_one


./configure \

    --prefix=$PREFIX \

    --enable-shared \

    --disable-static \

    --disable-doc \

    --disable-ffmpeg \

    --disable-ffplay \

    --disable-ffprobe \

    --disable-ffserver \

    --disable-avdevice \

    --disable-doc \

    --disable-symver \

    --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \

    --target-os=linux \

    --arch=arm \

    --enable-cross-compile \

    --sysroot=$SYSROOT \

    --extra-cflags="-Os -fpic $ADDI_CFLAGS" \

    --extra-ldflags="$ADDI_LDFLAGS" \


make clean


make install






We disabled static library and enabled shared library. Note that the build script is not optimized for a particular CPU. One should refer to ffmpeg documentation for detailed information about available configure options.

Once the file is saved, make sure the script is executable by the command below,

sudo chmod +x

Then execute the script by the command,


4. Build Output

The build can take a while to finish depending on your computer speed. Once it’s done, you should be able to find a folder $NDK/sources/ffmpeg-2.0.1/android, which contains arm/lib and arm/include folders.

The arm/lib folder contains the shared libraries, while arm/include folder contains the header files for libavcodec, libavformat, libavfilter, libavutil, libswscale etc.

Note that the arm/lib folder contains both the library files (e.g.: and symbolic links (e.g.: to them. We can remove the symbolic links to avoid confusion.

5. Make ffmpeg Libraries available for Your Projects

Now we’ve compiled the ffmpeg libraries and ready to use them. Android NDK allows us to reuse a compiled module through the import-module build command.

The reason we built our ffmpeg source code under $NDK/sources folder is that NDK build system will search for directories under this path for external modules automatically. To declare the ffmpeg libraries as reusable modules, we’ll need to add a file named $NDK/sources/ffmpeg-2.0.1/android/arm/ with the following content,

LOCAL_PATH:= $(call my-dir)


include $(CLEAR_VARS)

LOCAL_MODULE:= libavcodec





include $(CLEAR_VARS)

LOCAL_MODULE:= libavformat





include $(CLEAR_VARS)

LOCAL_MODULE:= libswscale





include $(CLEAR_VARS)

LOCAL_MODULE:= libavutil





include $(CLEAR_VARS)

LOCAL_MODULE:= libavfilter





include $(CLEAR_VARS)

LOCAL_MODULE:= libwsresample




Below is an example of how we can use the libraries in a Android project’s jni/ file,

LOCAL_PATH := $(call my-dir)


include $(CLEAR_VARS)


LOCAL_MODULE    := tutorial03

LOCAL_SRC_FILES := tutorial03.c

LOCAL_LDLIBS := -llog -ljnigraphics -lz -landroid

LOCAL_SHARED_LIBRARIES := libavformat libavcodec libswscale libavutil



$(call import-module,ffmpeg-2.0.1/android/arm)

Note that we called import-module with the relative path to $NDK/sources for the build system to locate the reusable ffmpeg libraries.

    i am compiling on ubuntu 14.x

  2. Folinio says:

    Could you please do a tutorial on ‘NDK r10b’ and ‘ffmpeg 2.3.3′

    It’s not working following this tutorial..

    –prefix=/home/me/android-ndk-r10b/sources/ffmpeg-2.3.3/android/arm: No such file or directory

    and more errors


  3. klemenp says:

    There’s a typo in /ffmpeg-2.0.1/android/arm/ example: ‘libwsresample’ should be ‘libswresample’.

  4. Michael says:

    Great tutorial, but a little outdated with files format. My tools: Ubuntu 13.10 x64, NDK r10b x64, ffmpeg 2.4.1.
    Spent 2.5 days, finally found out that my shell script doesn’t support multiline params format – params for ./configure should not contain line wraps and “\”. Also, $SYSROOT should not end with “/” – otherwise system will look for “” directory inside $NDK/platforms/android-L/arch-arm. Last thing – it is better to run “sudo ./”. Non-root users may have troubles with make and mkdir utils.

  5. dcmber12 says:

    your in $NDK/sources/… has little mistyping.
    the LOCAL_MODULE:= lib(ws)resample for actual libswresample. i spend 4 hours for that mistyped module name, after just copy-and paste your but however, good tutorial. thanks roman10.

  6. Deepak says:

    Thank you for the build script. I was able to build the script and use it in my project but while testing on AVD running Google API 10 and armeabi architecture SIGILL signal is thrown.
    I tried to find the instruction at the fault address f1010200 using arm-linux-androideabi-objdump tool and the instruction is “setend be”. I then checked on the arm site and it lists it as available on arm-v6 and above,

    Extract from the site:

    This ARM instruction is available in ARMv6 and above.
    This 16-bit Thumb instruction is available in T variants of ARMv6 and above, except the ARMv6-M and ARMv7-M architectures.
    There is no 32-bit version of this instruction in Thumb.

    I might be looking at wrong arm documentation, Do you know what is causing this error?

    I build done on Mac OS :)

  8. Override says:

    Could please post the steps you followed to build ffmpeg for android on MacOS.
