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

- Source code: gameobjects/Video.js (Line 833)
-
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 thesetTouchLock
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.
- Source code: gameobjects/Video.js (Line 954)
-
complete()
-
Called when the video completes playback (reaches and ended state).
Dispatches the Video.onComplete signal.- Source code: gameobjects/Video.js (Line 623)
-
connectToMediaStream(video, stream) → {Phaser.Video}
-
Connects to an external media stream for the webcam, rather than using a local one.

MediaStream The Video Stream data.
Returns
This Video object for method chaining.
- Source code: gameobjects/Video.js (Line 311)
-
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:
Blob([new Uint8Array(data)])
Returns
This Video object for method chaining.
- Source code: gameobjects/Video.js (Line 507)

-
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.
- Source code: gameobjects/Video.js (Line 530)
-
destroy()
-
Destroys the Video object. This calls
Video.stop
and thenVideo.removeVideoElement
.
If any Sprites are using this Video as their texture it is up to you to manage those.- Source code: gameobjects/Video.js (Line 1141)
-
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.
- Source code: gameobjects/Video.js (Line 1075)
-
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.
- Source code: gameobjects/Video.js (Line 635)
-
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.- Source code: gameobjects/Video.js (Line 1111)
-
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 totrue
.- Source code: gameobjects/Video.js (Line 859)
-
setTouchLock()
-
Sets the Input Manager touch callback to be Video.unlock.
Required for mobile video unlocking. Mostly just used internally.- Source code: gameobjects/Video.js (Line 1033)
-
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. CallVideo.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.
- Source code: gameobjects/Video.js (Line 337)
-
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 callingVideo.stop
will not abort the download. To do that you need to
callVideo.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.
- Source code: gameobjects/Video.js (Line 723)
-
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.- Source code: gameobjects/Video.js (Line 1046)
-
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
video.videoWidth
