I’ve documented the process of how I’m trying to perform DIY screencast recording, for the needs of a MOOC.
I’m working on my Debian or Ubuntu desktop, using an external graphic tablet with integrated display for annotating slides.
The main software used for the process are xournal for annotating PDFs and vokoscreen for the screen and video recording.
Here is the documentation : http://www-public.telecom-sudparis.eu/~berger_o/screencast-linux.html
And here’s the companion video : https://youtu.be/YxcUNqXPYZE
I hope this is useful to some.
