[Feature Request/Enhancement] Screen Capture

[vickipedia]

While screenshots are already allowed, it would be good to record the screen output and download the video stream until the user stops the recording. If that brings some overhead, we can specify duration of screen capture to X seconds or have a configurable threshold in the control pane.

Right now, this is possible using third party or 1P solutions (in Mac), but its counter intuitive when it comes to cropping/resizing to match the exact feed dimensions.
