Why decode to then turn around and re-encode?

Reading their product page, it seems like Recall captures meetings on whatever platform their customers are using: Zoom, Teams, Google Meet, etc.

Since they don't have API access to all these platforms, the best they can do to capture the A/V streams is simply to join the meeting in a headless browser on a server, then capture the browser's output and re-encode it.

They‘re already hacking Chromium. If the compressed video data is unavailable in JS, they could change that instead.

They did what every other startup does: put the PoC in production.
