# Record screen and microphone audio
# Stefan Siegert 2020, adapted from code by Steven Gordon
#
# Example usage:
#    screencast intro-to-datacomms
# The audio and screen will be recorded. Press 'z' to stop.
# Two files will be created: intro-to-datacomms-audio.flac, intro-to-datacomms-screen.mp4

To create a screencast using Linux command line tools I have used the methods outlined on this page:

https://sandilands.info/sgordon/multimedia-on-linux-command-line

(Ctrl-F screencast)

This might not be the easiest method, but it was simple enough for me and uses only tools that I had installed already.
