ffmpeg-android-maker

Here is a script that downloads the source code of FFmpeg library and assembles it for Android. The script produces shared libraries as well as header files. The output structure looks like this:

The actual content of all this directories depends on how the FFmpeg was configured before assembling. For my purpose I enabled only libavcodec, libavformat and libavutil, but you can set your own configuration to make the FFmpeg you need. The version of FFmpeg here is 4.1.3. And the script expects to use Android NDK r19 (b and c also work as well as r20-beta1). Starting with FFmpeg 4.1 and NDK r19 the whole process became much simpler.

Supported architectures

• armeabi-v7a
• arm64-v8a
• x86
• x86_64

Prerequisites

You have to define an environment variable ANDROID_NDK_HOME and set the correct path to your Android NDK.

How to use

Well, just execute the script :) Examine the output directory after.

Known issues:

The x86 binary doesn't have assembler optimizations, since they bring text relocations. So it may encounter certain performance issues. The x86_64 doesn't have this problem though.
