NotSupportedErrorsometimes gets thrown and in debugging why I noticed that Quagga is causing an unhandled rejection error here because it doesn't catch and propagate theNotSupportedErrorwhenvideo.play()is called on a video element that doesn't have a supported source (the cause of thatNotSupportedErroris completely unrelated to this PR).This is a small PR that fixes that, and wraps the
reject('Unable to play video stream. Is webcam working?')near the top of the file in an error object so it works better with our application logging and gives us a full stack-trace when it happens.
