## What it is
A free open-source tutorial series and companion codebase for learning FFmpeg-based audio and video development on Android. It covers building players, recorders, filters, audio visualization, and hardware decoding through 15 serialized blog articles with working C++/NDK sample code.

## Use cases
- learn how to integrate and compile FFmpeg for Android
- build a video player with FFmpeg and ANativeWindow
- implement audio playback with OpenSLES
- add video filters with OpenGL ES rendering
- sync audio and video in a custom media player
- record video with filters and encode with x264 and fdk-aac
- use MediaCodec for hardware video decoding
- build a 3D panoramic VR video player

## When to choose
- you are an Android developer learning multimedia development with FFmpeg and NDK
- you want step-by-step tutorials with runnable sample code for players and recorders
- you need examples combining FFmpeg with OpenGL ES, OpenSLES, or MediaCodec

## When to avoid
- you need a production-ready media player library rather than educational code
- you target iOS, desktop, or server platforms instead of Android
- you require a formally licensed dependency - the repository has no explicit license file
