Nobody has claimed this yet.

能，看到demo里面自定义压缩引擎只实现了图片的压缩方案！！！

希望大佬 能够拓展一下，支持视频的压缩，目前Android手机录2分钟的视频，大小已经超过500M！！！

## Describe the problem or provide an error log？
#### 描述问题或提供错误log？

```
com.luck.pictureselector I/PictureSelectorTag: 是否压缩:false
com.luck.pictureselector I/PictureSelectorTag: 压缩:null
com.luck.pictureselector I/PictureSelectorTag: 初始路径:content://media/external/video/media/46942
com.luck.pictureselector I/PictureSelectorTag: 绝对路径:/storage/emulated/0/Movies/VID_20221103205613257.mp4
```

Start by reviewing the demo's custom compression engine and the existing image-compression path, then trace how a selected video reaches the compression decision shown in the logs. Done means video selections can use a supported compression flow rather than reporting compression as null, with the demo reproducing the behavior.
