Access to media data streams--webcam video, microphone audio--from browser Javascript. Abbreviated gUM

getUserMedia provides access to data streams from media devices such as webcams and microphones. It is used from Javascript running in a user's web browser. It supports the development of front-end web application code for capturing media.

Support varies from browser to browser and device to device. See CanIUse.com for up-to-date information.

getUserMedia forms part of browser-resident WebRTC support (see ). It can be used by itself without establishing WebRTC connections.

getUserMedia is often abbreviated gUM. It's often used in conjunction with MediaRecorder; see .
