VideoSource

A data source containing video. (See the Style Specification for detailed documentation of options.)

Example

// add to map
map.addSource('some id', {
   type: 'video',
   url: [
       'https://www.mapbox.com/blog/assets/baltimore-smoke.mp4',
       'https://www.mapbox.com/blog/assets/baltimore-smoke.webm'
   ],
   coordinates: [
       [-76.54, 39.18],
       [-76.52, 39.18],
       [-76.52, 39.17],
       [-76.54, 39.17]
   ]
});

// update
let mySource = map.getSource('some id');
mySource.setCoordinates([
    [-76.54335737228394, 39.18579907229748],
    [-76.52803659439087, 39.1838364847587],
    [-76.5295386314392, 39.17683392507606],
    [-76.54520273208618, 39.17876344106642]
]);

map.removeSource('some id');  // remove

Add a video

Note that when rendered as a raster layer, the layer's raster-fade-duration property will cause the video to fade in. This happens when playback is started, paused and resumed, or when the video's coordinates are updated. To avoid this behavior, set the layer's raster-fade-duration property to 0.

Methods

getVideo()

getVideo(): HTMLVideoElement

Defined in: source/video_source.ts:139

Returns the HTML video element.

Returns

HTMLVideoElement

The HTML video element.

listens()

listens(type: string): boolean

Defined in: util/evented.ts:180

Returns a true if this instance of Evented or any forwardeed instances of Evented have a listener for the specified type.

Parameters

Parameter	Type	Description
`type`	`string`	The event type

Returns

boolean

true if there is at least one registered listener for specified event type, false otherwise

Inherited from

ImageSource.listens

loaded()

loaded(): boolean

Defined in: source/image_source.ts:196

True if the source is loaded, false otherwise.

Returns

boolean

Inherited from

ImageSource.loaded

loadTile()

loadTile(tile: Tile): Promise<void>

Defined in: source/image_source.ts:324

This method does the heavy lifting of loading a tile. In most cases it will defer the work to the relevant worker source.

Parameters

Parameter	Type	Description
`tile`	`Tile`	The tile to load

Returns

Promise<void>

Inherited from

ImageSource.loadTile

off()

off<T>(type: T, listener: (event: SourceEventType[T]) => void): this

Defined in: util/evented.ts:95

Removes a previously registered event listener.

Type Parameters

Type Parameter
`T` extends keyof `SourceEventType`

Parameters

Parameter	Type	Description
`type`	`T`	The event type to remove listeners for.
`listener`	(`event`: `SourceEventType`[`T`]) => `void`	The listener function to remove.

Returns

this

Inherited from

ImageSource.off

on()

on<T>(type: T, listener: (event: SourceEventType[T]) => void): Subscription

Defined in: util/evented.ts:78

Adds a listener to a specified event type.

Type Parameters

Type Parameter
`T` extends keyof `SourceEventType`

Parameters

Parameter	Type	Description
`type`	`T`	The event type to add a listen for.
`listener`	(`event`: `SourceEventType`[`T`]) => `void`	The function to be called when the event is fired. The listener function is called with the data object passed to `fire`, extended with `target` and `type` properties.

Returns

Subscription

Inherited from

ImageSource.on

once()

Call Signature

once<T>(type: T): Promise<SourceEventType[T]>

Defined in: util/evented.ts:110

Adds a listener that will be called only once to a specified event type.

The listener will be called first time the event fires after the listener is registered.

Type Parameters

Type Parameter
`T` extends keyof `SourceEventType`

Parameters

Parameter	Type	Description
`type`	`T`	The event type to listen for.

Returns

Promise<SourceEventType[T]>

a promise that resolves with the event

Inherited from

ImageSource.once

Call Signature

once<T>(type: T, listener: (event: SourceEventType[T]) => void): this

Defined in: util/evented.ts:120

Adds a listener that will be called only once to a specified event type.

The listener will be called first time the event fires after the listener is registered.

Type Parameters

Type Parameter
`T` extends keyof `SourceEventType`

Parameters

Parameter	Type	Description
`type`	`T`	The event type to listen for.
`listener`	(`event`: `SourceEventType`[`T`]) => `void`	The function to be called when the event is fired the first time.

Returns

this

this when a listener is provided

Inherited from

ImageSource.once

pause()

pause(): void

Defined in: source/video_source.ts:107

Pauses the video.

Returns

this

Overrides

ImageSource.prepare

seek()

Sets playback to a timestamp, in seconds.

Parameters

Parameter	Type

void

setCoordinates()

setCoordinates(coordinates: Coordinates): this

Defined in: source/image_source.ts:264

Sets the image's coordinates and re-renders the map.

Parameters

Parameter	Type	Description
`coordinates`	`Coordinates`	Four geographical coordinates, represented as arrays of longitude and latitude numbers, which define the corners of the image. The coordinates start at the top left corner of the image and proceed in clockwise order. They do not have to represent a rectangle.

updateImage()

updateImage(options: UpdateImageOptions): this

Defined in: source/image_source.ts:210

Updates the image and, optionally, the coordinates. To avoid having the image flash after changing, set the raster-fade-duration paint property on the raster layer to 0.

Provide exactly one of url (to fetch a new image over the network) or image (an already-decoded HTMLImageElement, HTMLCanvasElement, ImageBitmap or ImageData to display directly, without a network request).

Parameters

Parameter	Type	Description
`options`	`UpdateImageOptions`	The options object.

Returns

this

Inherited from
