https://obsproject.com/ is win/linux/mac and really good for this because you have a lot of options for compositing what you want to record e.g. include front-facing camera and mic which can be very revealing about body-language, facial expression and erm.. muttered expletives.

If we were working with a friend and saw the extremes of body-language we sometimes display obliviously when things are not going well, we would instantly recognise them as a cry for help and step in. When alone, we are liable to just dig a deeper hole.
