# App平台

App-Android平台video组件使用ijkplayer库实现:https://github.com/bilibili/ijkplayer

弹幕功能使用DanmakuFlameMaster库实现:https://github.com/bilibili/DanmakuFlameMaster

ijkplayer库的功能较多,video组件并非完全封装。有需要的开发者可以使用uts直接操作该库。

# Bug & Tips

  • 暂不支持横屏全屏后放置子组件
  • 标准运行基座默认不包含intel x86 cpu的兼容so库,所以video组件在标准基座运行时无法在x86 cpu的设备上运行(常见于模拟器)。如需支持x86 cpu,请在manifest里配置abiFilters,打包或自定义基座后生效 详见

# # 子组件

不可以嵌套组件

# # 参见

# 上下文对象API

video的操作api为uni.createVideoContext()

给video组件设一个id属性,将id的值传入uni.createVideoContext(),即可得到video组件的上下文对象,进一步可使用.play().stop()等方法。
