The MediaCapabilities interface of the Media Capabilities API
information about the decoding abilities of the device, system
browser. The API can be used to query the browser about the decoding
of the device based on codecs, profile, resolution, and bitrates.
information can be used to serve optimal media streams to the
and determine if playback should be smooth and power efficient.

The MediaDevicesInfo interface contains information that describes
single media input or output device.

The MediaDevices interface provides access to connected media
devices like cameras and microphones, as well as screen sharing.
essence, it lets you obtain access to any hardware source of
data.

The MediaError interface represents an error which occurred while
media in an HTML media element based on `html.HTMLMediaElement`,
as `web.<audio>` or `web.<video>`.

The MediaKeyMessageEvent interface of the EncryptedMediaExtensions
contains the content and related data when the content decryption
generates a message for the session.

The MediaKeys interface of EncryptedMediaExtensions API represents
set of keys that an associated `html.HTMLMediaElement` can use
decryption of media data during playback.

The MediaKeySession interface of the EncryptedMediaExtensions
represents a context for message exchange with a content decryption
(CDM).

The MediaKeyStatusMap interface of the EncryptedMediaExtensions
is a read-only map of media key statuses by key IDs.

The MediaKeySystemAccess interface of the EncryptedMediaExtensions
provides access to a Key System for decryption and/or a content
provider. You can request an instance of this object using the
method.

The MediaKeySystemConfiguration interface Encrypted Media Extensions
provides configuration information about the media key system.

The MediaMetadata interface of the the Media Session API provides
a web page to provide rich media metadata for display in a platform

A MediaQueryList object stores information on a media query applied
a document, with support for both immediate and event-driven
against the state of the document.

The MediaQueryListEvent object stores information on the changes
have happened to a `media.MediaQueryList` object — instances
available as the event object on a function referenced by a `media.MediaQueryList.onchange`
or `media.MediaQueryList.addListener()` call.

The MediaRecorder interface of the MediaStream Recording API
functionality to easily record media. It is created using the
constructor.

MediaRecorder Events.

The MediaRecorderErrorEvent interface represents errors returned
the MediaStream Recording API. It is an `web.Event` object that
a reference to a `dom.DOMException` describing the error that

The MediaSession interface of the Media Session API allows a
page to provide custom behaviors for standard media playback

The MediaSettingsRange interface of the the MediaStream Image
API provides the possible range and value size of `web.PhotoCapabilities.imageHeight`
`web.PhotoCapabilities.imageWidth`. A `web.PhotoCapabilities`
can be retrieved by calling `web.ImageCapture.PhotoCapabilities()`.

The MediaSource interface of the Media Source Extensions API
a source of media data for an `html.HTMLMediaElement` object.
MediaSource object can be attached to a `html.HTMLMediaElement`
be played in the user agent.

The MediaStream interface represents a stream of media content.
stream consists of several tracks such as video or audio tracks.
track is specified as an instance of `media.MediaStreamTrack`.

MediaStream Events.

Inherits properties from its parent, `audio.AudioNode`.

The MediaStreamAudioSourceNode interface is a type of `audio.AudioNode`
operates as an audio source whose media is received from a `media.MediaStream`
using the WebRTC or Media Capture and Streams APIs.

The MediaStreamAudioSourceOptions dictionary provides configuration
used when creating a `media.MediaStreamAudioSourceNode` using
constructor.

The MediaStreamConstraints dictionary is used when calling `web.getUserMedia()`
specify what kinds of tracks should be included in the returned
and, optionally, to establish constraints for those tracks' settings.

The MediaStreamEvent interface represents events that occurs
relation to a `media.MediaStream`. Two events of this type can
thrown: addstream and removestream.

The MediaStreamTrack interface represents a single media track
a stream; typically, these are audio or video tracks, but other
types may exist as well.

MediaStreamTrack Events.

The MediaStreamTrackAudioSourceOptions dictionary is used when
options to the `media.MediaStreamTrackAudioSourceNode()` constructor.

The MediaTrackConstraints dictionary is used to describe a set
capabilities and the value or values each can take on. A constraints
is passed into `web.applyConstraints()` to allow a script to
a set of exact (required) values or ranges and/or preferred values
ranges of values for the track, and the most recently-requested
of custom constraints can be retrieved by calling `web.getConstraints()`.

The MediaTrackSettings dictionary is used to return the current
configured for each of a `media.MediaStreamTrack`'s settings.
values will adhere as closely as possible to any constraints
described using a `media.MediaTrackConstraints` object and set
`web.applyConstraints()`, and will adhere to the default constraints
any properties whose constraints haven't been changed, or whose
constraints couldn't be matched.

The MediaTrackSupportedConstraints dictionary establishes the
of constrainable properties recognized by the user agent or browser
its implementation of the `media.MediaStreamTrack` object. An
conforming to MediaTrackSupportedConstraints is returned by `media.MediaDevices.getSupportedConstraints()`.
