The Mediastream returned from a canvas captureStream call can not be used to be rendered into another canvas using drawImage (2d context) or createImageBitmap/transferFromImageBitmap (bitmaprenderer context) The following CodePen shows the problem in a short example. https://codepen.io/sleb91/pen/bGQdPxq I have tested on Safari on Mac (Version 16.5 (18615.2.9.11.4)) and latest IOS Safari (16.5)
