Methods

Name	Description
AddTextTrack(TextTrackKind, string, string)	Creates a text track and adds it to the list of text tracks of the media element (https://html.spec.whatwg.org/multipage/media.html#dom-media-addtexttrack): the track is loaded, its mode is `TextTrackMode.Hidden` and its list of cues is empty. An `addtrack` event is fired at the list.
CanPlayType(string)	https://html.spec.whatwg.org/multipage/media.html#dom-navigator-canplaytype: the answer of the media backend (`MediaBackend.CanPlayType`) for a valid MIME type other than `application/octet-stream`, else the empty string. Without a media backend, no media type can be played.
FastSeek(double)	Seeks to near the given time, in seconds, as fast as possible (https://html.spec.whatwg.org/multipage/media.html#dom-media-fastseek).
GetStartDate()	Returns the date and time of the zero time of the media timeline (https://html.spec.whatwg.org/multipage/media.html#dom-media-getstartdate), or null when the media resource has none (the timeline offset is NaN: the scripts get a `Date` object whose time value is NaN, an "Invalid Date").
Load()	https://html.spec.whatwg.org/multipage/media.html#dom-media-load
Pause()	https://html.spec.whatwg.org/multipage/media.html#dom-media-pause
Play()	https://html.spec.whatwg.org/multipage/media.html#dom-media-play: returns a task that completes when the playback starts, or fails with a `NotAllowedError` (the autoplay policy), a `NotSupportedError` (the media resource is not suitable, or there is no media backend) or an `AbortError` (the element was paused or loaded another resource).

AddTextTrack(TextTrackKind, string, string)

Creates a text track and adds it to the list of text tracks of the media element (https://html.spec.whatwg.org/multipage/media.html#dom-media-addtexttrack): the track is loaded, its mode is TextTrackMode.Hidden and its list of cues is empty. An addtrack event is fired at the list.

public TextTrack AddTextTrack(TextTrackKind kind, string label = "", string language = "")

Parameters

kind TextTrackKind: The kind of the track.
label string: The label of the track.
language string: The language of the track (a BCP 47 language tag).

Returns

TextTrack The new track.

CanPlayType(string)

https://html.spec.whatwg.org/multipage/media.html#dom-navigator-canplaytype: the answer of the media backend (MediaBackend.CanPlayType) for a valid MIME type other than application/octet-stream, else the empty string. Without a media backend, no media type can be played.

public string CanPlayType(string type)

Seeks to near the given time, in seconds, as fast as possible (https://html.spec.whatwg.org/multipage/media.html#dom-media-fastseek).

public void FastSeek(double time)

Parameters

time double

GetStartDate()

Returns the date and time of the zero time of the media timeline (https://html.spec.whatwg.org/multipage/media.html#dom-media-getstartdate), or null when the media resource has none (the timeline offset is NaN: the scripts get a Date object whose time value is NaN, an "Invalid Date").

public DateTime? GetStartDate()
