Any advice ?

Thanks

Yes, you need to request a hole in the sandbox to access files.

Why does the MP3 play directly then ?

Posted: **18 Sep 2024 17:38**

I cannot tell without knowing your code. Probably you request access to the mp3 with something like

Code: Select all

[NSURL startAccessingSecurityScopedResource]

after finding the file with a system file picker? By doing that, your app will be granted access to that file but not to any further files mentioned in the m3u.

Im just using the VLC that I got from App Store for the iPad, trying to play an M3U list on a USB thumbdrive plugged into the iPad
No dev work, just usage problems

Sorry, misunderstood your request. Yes, VLC does not handle playlists with references outside the app container correctly at the moment. This is not overly complex but tiresome to do, so it wasn't done so far due to limited resources.
