I'm requesting a TAG review of Conversion to RGB in VideoFrame.copyTo().
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 make it possible to asynchronously convert frames to RGB pixel format by calling VideoFrame.copyTo() without having to use an extra canvas.
