cache mp4 video file not played by VideoPlayer package on ios

## 🐛 Bug Report

I use flutter cache manager last version to cache images and videos it works well on android also on ios it cache and shows image files perfectly, but cached mp4 or .ts video files can not be played by the Video player package on ios,
is it required any extra configuration or permission on ios?

**Platform:**
- [x] :iphone: iOS

The issue names no repository files or tests. Start by reproducing cached mp4 and .ts playback on iOS, comparing cached and uncached files, then inspect the cache manager and VideoPlayer integration to identify whether the failure is caused by caching or iOS configuration; done means cached videos play successfully on iOS or the required limitation is documented.
