Video Player Unity2017

Hi everybody, :slight_smile:
I want to play a video (.mp4) on a UI object with Video Player Component but i don’t succeed.
I use this to recover the url video:
3240530--249113--upload_2017-10-2_11-54-39.png

And its my object on Unity Editor:

I found.
Now, i don’t arrive to launch a video, who saved in the VideoLibrary of Hololens Headset, with Video Player Component but i arrive to launch a video who was in the asset folder when i compiled the project.
Can i do a copy of the file in the VideoLibrary ?
