1、安装
    	yarn add react-native-video
    
    2、导入
    	import Video from 'react-native-video';
    
    3、使用
    	<Video 
              ref='video'
              source={
       {uri:'https://video.699pic.com/videos/73/92/43/b_mPEcRsUxTkE91597739243.mp4'}} //url或本地文件
              volume={5} //放大声音倍数
              paused={false}  //是否暂停
              rate={this.state.rate}  //0/1,0暂停,1正常
              muted={false}  //静音
              resizeMode='contain' //视频适应方式
              repeat={true} //是否重复播放
              controls={true} //显示控制按钮
              
              onLoadStart={this.onLoadStart}
              onLoad={this.onLoad}
              	参数:currentPosition 	当前播放时间
    				duration	视频总时间
              onProgress={this.onProgress}  //视频播放每隔250毫秒触发,并携带当前已播放时间
              	参数:currentTime  当前播放时间
    			    playableDuration 	视频总时间
              onEnd={this.onEnd}
              onError={this.onError}
              style={styles.video}
         />
         
         4、方法
         ref对象.seek(n秒); 跳转到视频多少秒

代码示例:  
自定义进度条、播放结束暂停、点击视频暂停/播放:
