Specification
https://www.w3.org/TR/webcodecs/#dom-videoframe-copyto
Summary
VideoFrame.copyTo() can convert pixel data to RGB pixel format
Converting YUV video frames to RGB is often required for processing
them in libraries like TensorFlow.js and OpenCV.js. Previously the
only possible way to achieve this was rendering the frame on a canvas.
Specifying VideoFrameCopyToOptions.format and
VideoFrameCopyToOptions.colorSpace makes it possible to convert frames
to RGB pixel formats by calling VideoFrame.copyTo() without having to
use an extra canvas.
