It seems strange that we are not able to capture at VGA resolution.
I was not able to repro it locally.
Have you tried Safari Technology Preview?
Is there any MacOS console logging that you can share which points to some of these issues?

we can reproduce the issue 100% in two macbook air .
you can also reproduce the issue like this:
Click the VGA button first , you can get the video, then click the other button like QVGA button .

Can you give the exact Mac book air configuration?

So it seems that when you go VGA -> QVGA you loose the video.
Ditto for QVGA -> VGA, right?
We did a bunch of work in that area and I am wondering whether this might be already solved in Safari Technology Preview.
