## What it is
A collection of demo code accompanying a Chinese tutorial series on Android audio/video development. It covers hardware decoding with MediaCodec, software decoding with FFmpeg, rendering with OpenGL ES, audio playback with OpenSL ES, and muxing/demuxing into MP4.

## Use cases
- learn android audio video development
- decode video with mediacodec on android
- play video with ffmpeg and opengl es
- mux audio and video into an mp4 on android
- render video frames with opengl es
- decode audio with ffmpeg and opensl es
- get started with android multimedia programming

## When to choose
- you are learning Android audio/video development from scratch and want guided, step-by-step examples
- you want working sample code for MediaCodec, FFmpeg, OpenGL ES, and OpenSL ES in one project
- you prefer tutorial-style resources with accompanying blog articles

## When to avoid
- you need a production-ready media library or player to drop into your app
- you need up-to-date code or active maintenance (last release 2021)
- you need advanced or exhaustive coverage beyond an introductory series
- you cannot work with Chinese-language documentation

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: video-processing, audio-processing, graphics
- domain: mobile-development, tutorials, media
- platform: cpp, c
- tags: android, ffmpeg, mediacodec, opengl-es, opensl-es, audio-video, demo-code, chinese
