Throw error: Unhandled Promise Rejection: DataCloneError on Safari for iOS

Describe the bug

When I use ffmpeg.wasm on Safari or Chrome on iOS, an error occurs during the execution of ffmpeg.load({coreURL}).

To Reproduce

1. Access [video.frmachao.top](https://video.frmachao.top/) using Safari on IOS.
2. Click on the upload button, and after successful upload, click on the compress button.
