 - [Element Capture API example](https://mdn.github.io/dom-examples/screen-capture-api/element-capture): The same example, but this time using the [Element Capture API](https://developer.mozilla.org/docs/Web/API/Screen_Capture_extensions/Element_Region_Capture#the_element_capture_api) to restrict the broadcast stream to one particular rendered element inside the same tab the app is running in.
 - [Region Capture API example](https://mdn.github.io/dom-examples/screen-capture-api/region-capture): The same example, but this time using the [Region Capture API](https://developer.mozilla.org/docs/Web/API/Screen_Capture_extensions/Element_Region_Capture#the_region_capture_api) to crop the broadcast stream to the screen area in which one particular element is rendered, inside the same tab the app is running in.
