I am preparing my presentation with LaTeX, so my presentation file will be in Portable Document Format (PDF). I have access to Linux and Windows machines. An offline Linux solution is preferred.

With a Google Search, I find only solutions for Microsoft Powerpoint. Since I'm using other software to prepare my presentation, those solutions are not useful for me.

Answer 1

The Free and Open Source Software (FOSS) Open Broadcaster Software (OBS) Studio appears to have a rich selection of features that may allow doing exactly what you need. I haven't tried it yet, but it appears to let users select multiple sources (such as a webcam or an application window) for recording and arrange those on the screen. That should allow for a presenter video in a corner of the presentation. It also allows for filters to be applied to those sources; perhaps that allows for the outline/transparency visible in the dask video.
