Class: Phaser.Video
Constructor
new Video(game, key, url)
A Video object that takes a previously loaded Video from the Phaser Cache and handles playback of it.
Alternatively it takes a getUserMedia feed from an active webcam and streams the contents of that to
the Video instead (see startMediaStream
method)
The video can then be applied to a Sprite as a texture. If multiple Sprites share the same Video texture and playback
changes (i.e. you pause the video, or seek to a new time) then this change will be seen across all Sprites simultaneously.
Due to a bug in IE11 you cannot play a video texture to a Sprite in WebGL. For IE11 force Canvas mode.
If you need each Sprite to be able to play a video fully independently then you will need one Video object per Sprite.
Please understand the obvious performance implications of doing this, and the memory required to hold videos in RAM.
On some mobile browsers such as iOS Safari, you cannot play a video until the user has explicitly touched the screen.
This works in the same way as audio unlocking. Phaser will handle the touch unlocking for you, however unlike with audio
it's worth noting that every single Video needs to be touch unlocked, not just the first one. You can use the changeSource
method to try and work around this limitation, but see the method help for details.
Small screen devices, especially iPod and iPhone will launch the video in its own native video player,
outside of the Safari browser. There is no way to avoid this, it's a device imposed limitation.
Note: On iOS if you need to detect when the user presses the 'Done' button (before the video ends)
then you need to add your own event listener

currentTime : number
The current time of the video in seconds. If set the video will attempt to seek to that point in time.
disableTextureUpload : boolean
If true this video will never send its image data to the GPU when its dirty flag is true. This only applies in WebGL.
[readonly] duration : number
The duration of the video in seconds.
game : Phaser.Game
A reference to the currently running game.
height : number
The height of the video in pixels.
isStreaming : boolean
Is there a streaming video source? I.e. from a webcam.
key : string
The key of the Video in the Cache, if stored there. Will be null
if this Video is using the webcam instead.
loop : boolean
Gets or sets if the Video is set to loop.
Please note that at present some browsers (i.e. Chrome) do not support seamless video looping.
If the video isn't yet set this will always return false.
mute : boolean
Gets or sets the muted state of the Video.
onAccess : Phaser.Signal
This signal is dispatched if the user allows access to their webcam.
onChangeSource : Phaser.Signal
This signal is dispatched if the Video source is changed. It sends 3 parameters: a reference to the Video object and the new width and height of the new video source.
onComplete : Phaser.Signal
This signal is dispatched when the Video completes playback, i.e. enters an 'ended' state. On iOS specifically it also fires if the user hits the 'Done' button at any point during playback. Videos set to loop will never dispatch this signal.
onError : Phaser.Signal
This signal is dispatched if an error occurs either getting permission to use the webcam (for a Video Stream) or when trying to play back a video file.
onPlay : Phaser.Signal
This signal is dispatched when the Video starts to play. It sends 3 parameters: a reference to the Video object, if the video is set to loop or not and the playback rate.
onTimeout : Phaser.Signal
This signal is dispatched if when asking for permission to use the webcam no response is given within a the Video.timeout limit.
This may be because the user has picked Not now
in the permissions window, or there is a delay in establishing the LocalMediaStream.
paused : boolean
Gets or sets the paused state of the Video.
If the video is still touch locked (such as on iOS devices) this call has no effect.
playbackRate : number
Gets or sets the playback rate of the Video. This is the speed at which the video is playing.
[readonly] playing : boolean
True if the video is currently playing (and not paused or ended), otherwise false.
[readonly] progress : number
The progress of this video. This is a value between 0 and 1, where 0 is the start and 1 is the end of the video.
retry : integer
The current retry attempt.
retryInterval : integer
The number of ms between each retry at monitoring the status of a downloading video.
retryLimit : integer
When starting playback of a video Phaser will monitor its readyState using a setTimeout call.
The setTimeout happens once every Video.retryInterval
ms. It will carry on monitoring the video
state in this manner until the retryLimit
is reached and then abort.
[readonly] snapshot : Phaser.BitmapData
A snapshot grabbed from the video. This is initially black. Populate it by calling Video.grab().
When called the BitmapData is updated with a grab taken from the current video playing or active video stream.
If Phaser has been compiled without BitmapData support this property will always be null
.
texture : PIXI.Texture
The PIXI.Texture.
textureFrame : Phaser.Frame
The Frame this video uses for rendering.
timeout : integer
The amount of ms allowed to elapsed before the Video.onTimeout signal is dispatched while waiting for webcam access.
touchLocked : boolean
true if this video is currently locked awaiting a touch event. This happens on some mobile devices, such as iOS.
type : number
The const type of this object.
video :HTMLVideoElement
The HTML Video Element that is added to the document.
videoStream :MediaStream
The Video Stream data. Only set if this Video is streaming from the webcam via startMediaStream
.
volume : number
Gets or sets the volume of the Video, a value between 0 and 1. The value given is clamped to the range 0 to 1.
width : number
The width of the video in pixels.

add(object) → {Phaser.Video}
Updates the given Display Objects so they use this Video as their texture.
This will replace any texture they will currently have set.
Parameters
Name | Type | Description |
---|---|---|
object | Phaser.Sprite | Array.<Phaser.Sprite> | Phaser.Image | Array.<Phaser.Image> | Either a single Sprite/Image or an Array of Sprites/Images. |
Returns
This Video object for method chaining.
addToWorld(x, y, anchorX, anchorY, scaleX, scaleY) → {Phaser.Image}
Creates a new Phaser.Image object, assigns this Video to be its texture, adds it to the world then returns it.
Parameters
Name | Type | Argument | Default | Description |
---|---|---|---|---|
x | number | <optional> | 0 | The x coordinate to place the Image at. |
y | number | <optional> | 0 | The y coordinate to place the Image at. |
anchorX | number | <optional> | 0 | Set the x anchor point of the Image. A value between 0 and 1, where 0 is the top-left and 1 is bottom-right. |
anchorY | number | <optional> | 0 | Set the y anchor point of the Image. A value between 0 and 1, where 0 is the top-left and 1 is bottom-right. |
scaleX | number | <optional> | 1 | The horizontal scale factor of the Image. A value of 1 means no scaling. 2 would be twice the size, and so on. |
scaleY | number | <optional> | 1 | The vertical scale factor of the Image. A value of 1 means no scaling. 2 would be twice the size, and so on. |
Returns
The newly added Image object.
changeSource(src, autoplay) → {Phaser.Video}
On some mobile browsers you cannot play a video until the user has explicitly touched the video to allow it.
Phaser handles this via the setTouchLock
method. However if you have 3 different videos, maybe an "Intro", "Start" and "Game Over"
split into three different Video objects, then you will need the user to touch-unlock every single one of them.
You can avoid this by using just one Video object and simply changing the video source. Once a Video element is unlocked it remains
unlocked, even if the source changes. So you can use this to your benefit to avoid forcing the user to 'touch' the video yet again.
As you'd expect there are limitations. So far we've found that the videos need to be in the same encoding format and bitrate.
This method will automatically handle a change in video dimensions, but if you try swapping to a different bitrate we've found it
cannot render the new video on iOS (desktop browsers cope better).
When the video source is changed the video file is requested over the network. Listen for the onChangeSource
signal to know
when the new video has downloaded enough content to be able to be played. Previous settings such as the volume and loop state
are adopted automatically by the new video.
Parameters
Name | Type | Argument | Default | Description |
---|---|---|---|---|
src | string | The new URL to change the video.src to. | ||
autoplay | boolean | <optional> | true | Should the video play automatically after the source has been updated? |
Returns
This Video object for method chaining.
complete()
Called when the video completes playback (reaches and ended state).
Dispatches the Video.onComplete signal.
connectToMediaStream(video, stream) → {Phaser.Video}
Connects to an external media stream for the webcam, rather than using a local one.
Parameters
Name | Type | Description |
---|---|---|
video | HTMLVideoElement | The HTML Video Element that the stream uses. |
stream | MediaStream | The Video Stream data. |
Returns
This Video object for method chaining.
createVideoFromBlob(blob) → {Phaser.Video}
Creates a new Video element from the given Blob. The Blob must contain the video data in the correct encoded format.
This method is typically called by the Phaser.Loader and Phaser.Cache for you, but is exposed publicly for convenience.
Parameters
Name | Type | Description |
---|---|---|
blob | Blob | The Blob containing the video data: |
Returns
This Video object for method chaining.
createVideoFromURL(url, autoplay) → {Phaser.Video}
Creates a new Video element from the given URL.
Parameters
Name | Type | Argument | Default | Description |
---|---|---|---|---|
url | string | The URL of the video. | ||
autoplay | boolean | <optional> | false | Automatically start the video? |
Returns
This Video object for method chaining.
destroy()
Destroys the Video object. This calls Video.stop
and then Video.removeVideoElement
.
If any Sprites are using this Video as their texture it is up to you to manage those.
grab(clear, alpha, blendMode) → {Phaser.BitmapData}
Grabs the current frame from the Video or Video Stream and renders it to the Video.snapshot BitmapData.
You can optionally set if the BitmapData should be cleared or not, the alpha and the blend mode of the draw.
If you need more advanced control over the grabbing them call Video.snapshot.copy
directly with the same parameters as BitmapData.copy.
Parameters
Name | Type | Argument | Default | Description |
---|---|---|---|---|
clear | boolean | <optional> | false | Should the BitmapData be cleared before the Video is grabbed? Unless you are using alpha or a blend mode you can usually leave this set to false. |
alpha | number | <optional> | 1 | The alpha that will be set on the video before drawing. A value between 0 (fully transparent) and 1, opaque. |
blendMode | string | <optional> | null | The composite blend mode that will be used when drawing. The default is no blend mode at all. This is a Canvas globalCompositeOperation value such as 'lighter' or 'xor'. |
Returns
A reference to the Video.snapshot BitmapData object for further method chaining.
play(loop, playbackRate) → {Phaser.Video}
Starts this video playing if it's not already doing so.
Parameters
Name | Type | Argument | Default | Description |
---|---|---|---|---|
loop | boolean | <optional> | false | Should the video loop automatically when it reaches the end? Please note that at present some browsers (i.e. Chrome) do not support seamless video looping. |
playbackRate | number | <optional> | 1 | The playback rate of the video. 1 is normal speed, 2 is x2 speed, and so on. You cannot set a negative playback rate. |
Returns
This Video object for method chaining.
removeVideoElement()
Removes the Video element from the DOM by calling parentNode.removeChild on itself.
Also removes the autoplay and src attributes and nulls the reference.
render()
If the game is running in WebGL this will push the texture up to the GPU if it's dirty.
This is called automatically if the Video is being used by a Sprite, otherwise you need to remember to call it in your render function.
If you wish to suppress this functionality set Video.disableTextureUpload to true
.
setTouchLock()
Sets the Input Manager touch callback to be Video.unlock.
Required for mobile video unlocking. Mostly just used internally.
startMediaStream(captureAudio, width, height) → {Phaser.Video}
Instead of playing a video file this method allows you to stream video data from an attached webcam.
As soon as this method is called the user will be prompted by their browser to "Allow" access to the webcam.
If they allow it the webcam feed is directed to this Video. Call Video.play
to start the stream.
If they block the webcam the onError signal will be dispatched containing the NavigatorUserMediaError
or MediaStreamError event.
You can optionally set a width and height for the stream. If set the input will be cropped to these dimensions.
If not given then as soon as the stream has enough data the video dimensions will be changed to match the webcam device.
You can listen for this with the onChangeSource signal.
Parameters
Name | Type | Argument | Default | Description |
---|---|---|---|---|
captureAudio | boolean | <optional> | false | Controls if audio should be captured along with video in the video stream. |
width | integer | <optional> | The width is used to create the video stream. If not provided the video width will be set to the width of the webcam input source. | |
height | integer | <optional> | The height is used to create the video stream. If not provided the video height will be set to the height of the webcam input source. |
Returns
This Video object for method chaining or false if the device doesn't support getUserMedia.
stop() → {Phaser.Video}
Stops the video playing.
This removes all locally set signals.
If you only wish to pause playback of the video, to resume at a later time, use Video.paused = true
instead.
If the video hasn't finished downloading calling Video.stop
will not abort the download. To do that you need to
call Video.destroy
instead.
If you are using a video stream from a webcam then calling Stop will disconnect the MediaStream session and disable the webcam.
Returns
This Video object for method chaining.
unlock()
Enables the video on mobile devices, usually after the first touch.
If the SoundManager hasn't been unlocked then this will automatically unlock that as well.
Only one video can be pending unlock at any one time.
updateTexture(event, width, height)
Called automatically if the video source changes and updates the internal texture dimensions.
Then dispatches the onChangeSource signal.
Parameters
Name | Type | Argument | Description |
---|---|---|---|
event | object | <optional> | The event which triggered the texture update. |
width | integer | <optional> | The new width of the video. If undefined |
height | integer | <optional> | The new height of the video. If undefined |
