I have tried to capture various video streams running in my browser using a plethora of screen capture and video recording tools. However, some streams prove hard to pin down. When I activate the recording tool – all of a sudden the video goes blank or black. And my recording is useless.

I am not sure whether this is an intended protection or a technical flaw. Anyway, it is hugely annoying. I have found a workaround: when the video stream is running inside a Windows Sandbox – and the capturing tool runs outside the sandbox – I now all of a sudden can take screen captures and make recordings as desired.
For details on how to get going with Windows Sandbox, check this article.
