The skater punk’s guide to MediaRecorder

The article discusses the use of MediaRecorder, a set of browser APIs that can capture screen and computer audio and video to produce video recordings right in your browser. It explains how to define constraints, get a stream handle for webcam and microphone or device screen, pass the stream to the MediaRecorder, operate the MediaRecorder, finish up the recording, and send it. The author also provides an open-source production example: stream.new, which implements the MediaRecorder API to allow users to record their screen or webcam and upload the results to Mux for free hosting.
