考虑到开发直播和视频播放的必要性，网上了解到b站开源播放器()好用，集成下试试。

运行后发现b站原生的只能播放没有其他选项，考虑到方便性，采用这个方案:

步骤

1.gradle集成(JCenter什么的别忘了)

//ijkplayer的封装    implementation 'com.shuyu:gsyVideoPlayer-java:6.0.3'    //是否需要ExoPlayer模式    implementation 'com.shuyu:GSYVideoPlayer-exo2:6.0.3'    //根据你的需求ijk模式的so    implementation 'com.shuyu:gsyVideoPlayer-armv5:6.0.3'    implementation 'com.shuyu:gsyVideoPlayer-armv7a:6.0.3'    implementation 'com.shuyu:gsyVideoPlayer-arm64:6.0.3'    implementation 'com.shuyu:gsyVideoPlayer-x64:6.0.3'    implementation 'com.shuyu:gsyVideoPlayer-x86:6.0.3'    //弹幕    implementation  'com.github.ctiao:DanmakuFlameMaster:0.9.16'    compile 'com.github.ctiao:ndkbitmap-armv7a:0.9.21'    compile 'com.github.ctiao:ndkbitmap-armv5:0.9.21'    compile 'com.github.ctiao:ndkbitmap-x86:0.9.21'

2.播放器的封装
