display-mode is a CSS media feature that selectively applies CSS based on the display mode of the application. This feature corresponds the Web app manifest's display member. Both apply to the top-level browsing context and any child browsing contexts. This query applies regardless of whether a web app manifest is present. Use this query to provide a consistant user experience between launching a site from an URL and lunching it from a desktop icon.
The MediaRecorder.requestData() method (part of the MediaRecorder API) is used to raise a dataavailable event containing a Blob object of the captured media as it was when the method was called. This can then be grabbed and manipulated as you wish.
Media Queries is a module of CSS that defines expressions allowing to tailor presentations to a specific range of output devices without changing the content itself.
The MediaStreamTrackinterface represents a single media track within a stream; typically, these are audio or video tracks, but other track types may exist as well.
The MediaTrackSettings dictionary is used to return the current values configured for each of a MediaStreamTrack's settings. These values will adhere as closely as possible to any constraints previously set using applyConstraints(), and will adhere to the default constraints for any properties whose constraints haven't been changed, or whose customized constraints couldn't be matched.
