## What it is
DanmakuFlameMaster is Bilibili's open-source Android danmaku (bullet comment) engine that parses and renders scrolling comments over video. It supports multiple rendering approaches (View/SurfaceView/TextureView), Bilibili XML danmaku format, and efficient caching for smooth performance.

## Use cases
- add danmaku bullet comments to an android video player
- parse bilibili xml danmaku files
- render scrolling comments over video on android
- build a video app with live danmaku overlay
- customize danmaku fonts and display effects
- filter or block danmaku by rules in an android app

## When to choose
- you need battle-tested danmaku rendering on Android (it powers the Bilibili app)
- you need to parse Bilibili XML danmaku format
- you need high-performance rendering with SurfaceView/TextureView and caching

## When to avoid
- you need danmaku on iOS, web, or desktop platforms
- you need OpenGL ES rendering (still a TODO)
- you need an actively developed project - the latest release was in 2020
