## What it is
A comprehensive Android video player library that wraps IJKPlayer, Media3 (ExoPlayer), MediaPlayer, and AliPlayer behind a unified API. It adds rich features such as danmaku (bullet chat), external subtitles, filters, watermarks, GIF screenshots, ads, play-while-cache, and multi-instance playback.

## Use cases
- play videos in an android app with danmaku bullet chat overlay
- android video player with external srt and webvtt subtitles
- cache video while streaming on android
- add watermarks and filters to video playback
- show pre-roll and mid-roll ads before videos
- play multiple videos simultaneously in a list
- capture video frames as screenshots or gif
- switch between ijkplayer exoplayer and mediaplayer kernels

## When to choose
- you need a feature-rich Android video player with danmaku, subtitles, ads, and caching out of the box
- you want to switch playback kernels (IJK/ExoPlayer/MediaPlayer) without rewriting UI code
- you need list playback, small-window/floating playback, or multi-instance playback

## When to avoid
- you are building for iOS, desktop, or web rather than Android
- you only need simple one-off playback and prefer the lightweight platform MediaPlayer directly
- you need a cross-platform Flutter or React Native player
