Xamarin ios Share Extension Crashes on try to get stream of an .mov file

Question

We currently are workiong on an share extension (xamarin ios) for mediafiles. Every thing working fine expecpt .mov files.

Every kind of attempt to load them in an stream or get any bit of the shared .mov files failed with an app crash.

Could anyone say why or has an solution for this kind of poblem?

We tried: NSData .AsSteam/.ToArray and foreach File.Load FileInfo.openRead AVAssets
