So, how to select video file by FilePicker (result is StorageFile) and use the result to set source and play video file by VideoLAN.LibVLC.UWP. The problem is following: I can get path but not permission to the folder. Only solution is pick the folder by FolderPicker, add the folder to the FutureAccessList and after that pick video file individually. So , hoping to find some other way to do this.
