Support for meeting recording, either on the client or in the server.

> It works by launching a Chrome instance rendered in a virtual framebuffer and capturing and encoding the output with ffmpeg. — [Jibri, JItsi BRoadcasting Infrastructure](https://github.com/jitsi/jibri#readme)

Similarly,

- [plugNmeet Recorder](https://github.com/mynaparrot/plugNmeet-recorder#readme) uses Chromium and FFmpeg.
- [Nextcloud Talk Recording](https://github.com/nextcloud/nextcloud-talk-recording/blob/main/docs/installation.md) uses Firefox and FFmpeg

Start by reviewing the Jibri, plugNmeet Recorder, and Nextcloud Talk Recording references linked in the issue. The issue does not name repository files, tests, or an entry point, and completion criteria for local versus server-side recording still need to be defined.
