mediaDeviceInfo
The MediaDevicesInfo interface contains information that describes a single media input or output device.See MediaDeviceInfo on MDN
typemediaDeviceInfo= {deviceId:string,kind:mediaDeviceKind,label:string,groupId:string,}Record fields
Module
There are methods and helpers defined in MediaDeviceInfo.
mediaDeviceKind
typemediaDeviceKind=| @as("audioinput")Audioinput| @as("audiooutput")Audiooutput| @as("videoinput")VideoinputmediaDevices
Provides access to connected media input devices like cameras and microphones, as well as screen sharing. In essence, it lets you obtain access to any hardware source of media data.See MediaDevices on MDN
typemediaDevices= {}Module
There are methods and helpers defined in MediaDevices.
mediaStream
A stream of media content. A stream consists of several tracks such as video or audio tracks. Each track is specified as an instance of MediaStreamTrack.See MediaStream on MDN
typemediaStream= {id:string,active:bool}Record fields
Module
There are methods and helpers defined in MediaStream.

mediaStreamTrack
A single media track within a stream; typically, these are audio or video tracks, but other track types may exist as well.See MediaStreamTrack on MDN
typemediaStreamTrack= {kind:string,id:string,label:string,mutableenabled:bool,muted:bool,readyState:mediaStreamTrackState,mutablecontentHint:string,}Record fields
Module
There are methods and helpers defined in MediaStreamTrack.
