视频压缩是怎么用的?

是这样吗？
```
 NativeModules.AssetExport.exportVideo('file:///storage/6185-09EC/DCIM/Camera/VID_20180120_143753.mp4', {width: 500, height: 500} ,uri => {
          if(uri.startsWith('file://'))
              uri = uri.substring(7);
          console.log(uri);// the uri is the compressed video path
`});`  
```
