Website unable to read the frames when I change the Camera.

Hi,

@arturaugusto first of all I really like your work, it is amazing the amount of effort you have put in this great project.

The Issue
There is an issue the however needs to be fixed quickly on your part, and that is if you have another camera that you want to use on
https://arturaugusto.github.io/7seg-ocr when you change your camera it doesn't pick it up in the window below for thresholding.

That is quite a big issue and renders the website unuseable for many people that includes me.

Other Issues
One other issue I found was that I was unable to get it running on a Phone when I opened the website particulary on Safari.
