How can we stop the camera after read the QR code?

[satyapratap-dev]

Hi Team,
Can we stop the camera/video once QR code scans completed? Let's say I am trying to capturing specific type format QR codes(like emails/mobile number) only. so, if any one of the QR format matches then it should quit/close the QR code scanning(close the camera). Please advise.

You can use video.srcObject.stop(); using the example of https://cozmo.github.io/jsQR/. You're going to need to append to stream this object.

stream.stop = function () { this.getAudioTracks().forEach(function (track) { track.stop(); }); };

I also recommend you to clean up video references and detach them from the DOM when you are no longer using them (for the sake of ram usage).
