opencv4nodejs: Error: VideoCapture::New - failed to open capture

const cap = new cv.VideoCapture('./roadtest1.mp4');
// Error: VideoCapture::New - failed to open capture

I get the same results with an RTSP stream as well.

This is on version 4.5.1 (autobuilt) on a fresh Ubuntu install, the only things i’ve installed are Node 8.11.2 and cmake (following these instructions).

I have not installed OpenCV independently at all.

I can do things like this, no problem:

const img = new cv.Mat();

Any ideas?!
