i'm developing an app that export audio file stored in the iPod library, but i should verify the file size before export and upload (server has a fixed max upload size):
- i know that after exporting file, the size will not be the same: is there any method to estimate the new size ?
- main question : can i know the original file size before export (using MPMediaItem or something else), so i can tell user that this file can't be uploaded (the export can take a while). thanks.
I have not tested but AVAssetExportSession can help you with this.
exporter.estimatedOutputFileLength will give you size in bytes.
