Using a linked file for the 3D Video resource instead of an upload

[Aouellets]

Hi all, 

Rather than using a file loaded via the uploads folder in editor, I would like to direct the 3D Video widget resource to a web hosted link. 

There's a variety of videos I'd like to be able to load programmatically rather than uploading each individual video. 

Note: Intended use is on 3D Eyewear i.e. the HoloLens

External link works with Mobile Project and 2D Other Widget Video.

But with 3D Eyewear 3D Video Widget, errors as below.

Error: [$interpolate:interr]

Uncaught DOMException: Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported.
