Code Overview

The code imports the necessary packages and initializes a publisher using the OpenTok client library.

There are two main functionalities:

1. QR Code: The applyQrCode function generates a QR Code from the provided text input and applies it to the video stream.

2. Watermark: The applyWatermark function overlays an uploaded image onto the video stream.

The flipImage function is used to flip the image horizontally. This is necessary because the publisher's video stream is mirrored by default.
