## Health v2 (maintenance only)
Score: 77/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 99, release rhythm 35, longevity 100
- inputs: {"age_days": 2058, "days_push": 8, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A curated learning resource (blog/GitBook) for audio/video development, covering YUV, PCM, H.264/H.265, AAC, RTMP, FFmpeg, OpenGL, and related tools, books, tutorials, interview questions, and open-source projects. It includes guided practice projects such as an RTMP streaming pipeline and a simple player built with FFmpeg, MediaCodec, OpenSL ES, and OpenGL ES.

## Use cases
- learn audio and video development from scratch
- understand YUV, PCM, H.264, and AAC fundamentals
- find FFmpeg and OpenGL learning resources and tutorials
- build an RTMP live streaming push project
- build a simple media player with FFmpeg and MediaCodec
- prepare for audio/video developer interviews
- find recommended books and open-source projects for multimedia development

## When to choose
- you are starting or advancing a career in audio/video development
- you need a structured roadmap of multimedia concepts, tools, and practice projects
- you want curated Chinese-language tutorials and book recommendations for codecs and streaming

## When to avoid
- you need production-ready streaming or playback code rather than learning material
- you need English-language documentation only
- you need a maintained software library with an API rather than a resource collection
