Part of desktop a webcam source
I would like to have the possibility so select a part of the desktop as source for the webcam.
I use a Canon DSLR as webcam. Via a Canon utility, the image is shown on the desktop. Currently I need to use a third party application that allows me to select a part of the desktop and offer that as a "virtual webcam". Then I select that virtual webcam as the webcam source in screencast-o-matic.
Would be nice if this could be done in screencast-o-matic directly
