So I'm doing some qimage analysis/manipulation. I think it would be really good

Never tried it. I don't know why it it wouldn't work. But in my system we had the server generate the pdf, which we had to use -platform offscreen or something like that.
The PDF stuff requires at least a QGuiApplication, which a mobile app is already.

I have no idea what I'm doing wrong. Can someone this and let me know?
The frames I'm getting are BGR32, so I have special code for that.
But I'm getting the message "QVideoFrame::unmap() was called more times then
QVideoFrame::map()"
Which is obviously not the case.
To restate the problems:

Your questions aren't really answerable. What are the concerns?
Define "isolation": thread, process, bus, other?
Why are you asking Qt? Websockets are not Qt. They are a RFC (6455). Are you
asking specifically about Qt's implementation? It sounds like you are asking a
more general question.
