I need to record a presentation and would like to include a video of my face in a corner, such as in this example:

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.

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.
