Question: How to use FFmpeg built by VPlayer (version 0.3.2 at the time I write this Gist) in Android Studio?

Answer This will take the FFmpeg built from here and use it as a library for our project in Android Stuio in Window 10.

1. Download NDK from here, uncompress it to anywhere you want (C:\Users\Viet\AppData\Local\Android\ndk\android-ndk-r11c in my case).
2. Copy the whole VPlayer_lib folder build from here into the root of your project.
3. In Android studio, click on app -> F4 -> SDK Location -> Android NDK location.
4. Edit/create gradle.properties file in the root folder of your project with android.useDeprecatedNdk=true.
