iOS plugin : send video to unity

I need to find recent video file and play on unity video texture

On iOS plugin i use ALAsset to get recent video file but ALAsset’s file url is not ‘file://’ but ‘assets-library://’
And when check System.IO.File.Exists(“assets-library://~~~”) return false on Unity C#

there is no way to get video list and file path without UIImagePickerController?

Ex) noon vr
