How slow does the video stream goes on your platform? #106

I'm testing the solution on 2 laptops with average specs (i5 with at least 8GB RAM, both on Debian). On one it works very smooth but on the other one the stream goes with at least 2-3 seconds delay. On the slow one I use : Chromium Version 71.0.3578.80 (Developer Build) built on Debian 9.6, running on Debian 9.6 (64-bit)

The slow line is actually the getImageData call.

Any ideas why? Thanks!

Changing to Chrome everything works smoothly.
