+# Prebuilt FFmpeg Android
+This repo contains build scripts to build FFmpeg executable binary for Android and also [publish prebuilt files here](https://github.com/Khang-NT/ffmpeg-binary-android/releases).
+There are two build flavors: _FULL_ and _LITE_
+  * **LITE** is a version that optimized binrary size, so it only includes small set features to work with most commom formats and codecs.
+    + ABI and android version supported:
+      - `armeabi` (Android 16+)
+      - `armeabi-v7a`, `armeabi-v7a-neon`, (Android 16+)
+      - `x86`  (Android 16+)
+      - `arm64-v8a`  (Android 21+)
+      - `x86_64` (Android 21+)
+      - ~~`mips`  (Android 16+)~~ (No longer support)
+      - ~~`mips64` (Android 21+)~~ (No longer support)
+    + Addition libraries: `libmp3lame`, `libshine`, `libopus`, `libvorbis`
+  * **FULL** is a version compiled full FFmpeg feature, include **https** support protocol.
+    + ABI and android version supported:
+      - `armeabi` (Android **21+**)
+      - `armeabi-v7a`, `armeabi-v7a-neon`, (Android **21+**)
+      - `x86`  (Android **21+**)
+      - `arm64-v8a`  (Android 21+)
+      - `x86_64` (Android 21+)
+    + Include libraries in `LITE` version, plus with: `libfdk-aac` (**non-free**), `libx264`, **`openssl`** (thanks to [leenjewel/openssl_for_ios_and_android](https://github.com/leenjewel/openssl_for_ios_and_android))

+## Download
+Latest build: [![Latest build](https://img.shields.io/github/release/Khang-NT/ffmpeg-binary-android.svg?style=for-the-badge)](https://github.com/Khang-NT/ffmpeg-binary-android/releases)
 
 ## Build  
-You can build it and customize as you want using build scripts in [build_scripts](build_scripts) folder. (Recommended using Android NDK r15).
-```
-export NDK="path/to/ndk-r15"
-./build_all.sh
+
+Prerequisites:
+  * Android NDK r15
+  * `export NDK=path/to/android-ndk`
+
+Build:
+```bash
+export NDK=path/to/android-ndk
+cd build_scripts
+
+FLAVOR=full       # or "lite"
+TARGET=armv7-a    # Support targets: "arm", "armv7-a", "arm-v7n", "arm64-v8a", "i686", "x86_64"
+BUILD_DIR=$(pwd)/build_dir
+FINAL_DIR=$(pwd)/final/$TARGET
+
+./build_ffmpeg.sh $TARGET $FLAVOR $BUILD_DIR $FINAL_DIR
 ```
 
-## Referent
+The `ffmpeg` binary should in folder `$FINAL_DIR/$TARGET/$FLAVOR/ffmpeg` after build succeed.
