Hi
I met an error

Segmentation fault (core dumped)
npm ERR! code ELIFECYCLE
npm ERR! errno 139

I've debugged and confirmed that videoCap.read () worked fine,
const image = cv.imencode('. jpg', frame).toString('base64'); I noticed an error here.

My node version is v12.14.1 and npm version is 6.13.6.

help me plz..
