I have been trying to read ID3 tags and other metadata from media files (like mp3 files) stored on the sd card on Android (ultimately iOS too ).
I can read files and load their content in memory with https://ionicframework.com/docs/native/file/
readAsArrayBuffer method for instance.
The big drawback of this method is I must load the entire file into memory when obviously the meta data is only a few hundred bytes at the begninning or end.
It takes about 10 seconds per file with the current method. This is not acceptable for a large collection or even a single album.
So I need to find a way to read only part a a file that is stored on the SD card, a.k.a.
Is there a cordova plugin for that? Is it even theoretically possible?
