That's correct, I use https://github.com/tensorflow/tfjs-models/tree/master/body-p...

It is indeed slow. The video signal first is drawn to a canvas and then from there streamed as a video again. Some browsers perform better than others. Probably due to WASM support, but I did not dig deeper here.

The "pro" though is it all happens on the client in the browser.
