"Hidden" gems of VLC

Today I found out the power of the "Devices" items in the VLC application.
With that I mean the option to record:
  • a videocast with the computer's camera [Video capture]
    Video effects, although can be seen on screen, are not recorded.
  • the usage of some application through its window (or the whole desktop, if you like) [Screen capture]
Audio capture didn't worked for me; maybe it's a configuration thing or a conflict, since video recordings had also no audio at all.
