I got an error when using the webcam.
It seems that createObjectURL() is deprecated:
sourcey/libsourcey#264
It worked when I changed the file atom\packages\veda\node_modules\vedajs\lib\camera-loader.js
from this.video.src = window.URL.createObjectURL(stream);
to this.video.srcObject = stream;
I don't really know how to fix this with a fork and a pull request, because it seems to be a nested package, so I'm opening an issue to acknowledge the problem.
