We introduce a performant and robust API for cropping a self-capture video track. (Recall that applications may *already* video-capture the tab in which the application is run using getDisplayMedia(). Using our new Region Capture, such an application may now *crop* that track and remove some content from it; typically before sharing it remotely.)


Applications need a performant and robust way to crop video tracks. For example, applications that combine video-conferencing and productivity-suite may wish to capture themselves, but only send the productivity-suite portion of themselves to remote participants, thereby avoiding a hall-of-mirrors effect.
