I was able to install the screen capture recorder and still no joy. How do the commercial vendors do it?

As already mentioned, the hardware acceleration of your browser can apparently not be captured.

You're using gdigrab for video. Have you tried adding the dshow capture device?
If you install it, your "ffmpeg -list_devices true -f dshow -i dummy"
should show a new video device "screen-capture-recorder". Perhaps that works for you. (I have no experience with it - it may suffer the same limitation. Please do report.)
