HoloVideoObject
HoloVideoObjectThreeJS

HoloVideoObject

Kind: global class

new HoloVideoObject()

HoloVideoObject is the internal web player implementation that interacts directly with WebGL (independent of three.js). HoloVideoObjectThreeJS defines the public interface for three.js development.

HoloVideoObject.States : enum

HoloVideoObject States

Kind: static enum of HoloVideoObject
Read only: true
Properties

Name Type Default Description
Closed number -1 A previously loaded capture has been unloaded. A new capture may be opened by calling open
Empty number 0 Initial state of all HoloVideoObjectThreeJS instances
Opening number 1 A capture is in the process of opening and buffering data for playback.
Opened number 2 The capture loaded and ready for play to be called
Playing number 3 Capture playback is in progress
Paused number 4 Playback is paused and may be resumed by calling play

HoloVideoObject.ErrorStates : enum

HoloVideoObject ErrorStates

Kind: static enum of HoloVideoObject
Read only: true
Properties

Name Type Default
NetworkError number -1
VideoError number -2
PlaybackPrevented number -3

HoloVideoObject.StreamMode : enum

HoloVideoObject StreamMode - set as an option to HoloVideoObject.open() to force the StreamMode for the video element

Kind: static enum of HoloVideoObject
Properties

Name Type Default
Automatic number 0
MP4 number 1
HLS number 2
Dash number 3

HoloVideoObject.VideoStates : enum

HoloVideoObject VideoStates

Kind: static enum of HoloVideoObject

HoloVideoObject~errorCallback : function

Kind: inner typedef of HoloVideoObject

Param Type Description
error ErrorStates type - Value from HoloVideoObject#ErrorStates enum indicating the type of error encountered.
additional Object error information (see description of specific HoloVideoObject#ErrorStates value for more information).

HoloVideoObjectThreeJS

Kind: global class

new HoloVideoObjectThreeJS(renderer, callback, options)

Creates a new HoloVideoObjectThreeJS instance

Param Type Description
renderer THREE.WebGLRenderer WebGLRenderer that will be used to render the capture.
callback openCallback Callback invoked when initial loading is complete.
options Object Optional collection of options that permanently affect behavior of this HoloVideoObjectThreeJS instance.
options.disableAsyncDecode boolean Disables asynchronous video decoding path which may result in improved audio sync but incurs a performance penalty. This is the only decoding path available in WebGL1 environments.
options.numAsyncFrames boolean Controls how many asynchronous frames are buffered in WebGL2 async. decode path resulting in 'numAsyncFrames' - 1 frames of latency. The default value is 3.
function Callback invoked when currentFrame is updated
errorCallback Callback invoked when unexpected error condition is encountered, see HoloVideoObject#ErrorStates for list of possible conditions.

holoVideoObjectThreeJS.state : States

The current state of this HoloVideoObjectThreeJS instance.

Kind: instance property of HoloVideoObjectThreeJS

holoVideoObjectThreeJS.open(url, options)

Opens and capture and begins buffering data for playback

Kind: instance method of HoloVideoObjectThreeJS

Param Type Description
url string Capture URL, e.g. "http://127.0.0.1/mycapture.hcap"
options Object Optional collection of options related to capture loading and playback.
options.audioEnabled boolean Specifies whether audio playback is enabled initially
options.autoplay boolean Specifies whether capture should automatically begin playback when loaded. If enabled will disable audio as many browsers do not allow automatic audio playback without user input.
options.streamMode StreamMode Force the streamMode for the video object. Default is Automatic.
options.minBuffers number Minimum number of .bin segments that must be buffered before capture is considered preloaded. Default value is 2.
options.maxBuffers number Maximum number of .bin segments that can be buffered and kept in memory at one time.
options.keepAllMeshesInMemory boolean Overrides maxBuffers setting and keeps all mesh in memory to prevent further loading.
options.startTime boolean Time in seconds where playback should begin from. Defaults to 0 if not specified.

holoVideoObjectThreeJS.update()

Updates capture mesh and texture to latest playback frame. This should be called periodically from the application's animate/update loop.

Kind: instance method of HoloVideoObjectThreeJS

holoVideoObjectThreeJS.rewind()

Rewinds capture back to the first frame and pauses.

Kind: instance method of HoloVideoObjectThreeJS

holoVideoObjectThreeJS.seekToTime(seekTime, displayImmediately)

Seeks playback position to the specified time.

Kind: instance method of HoloVideoObjectThreeJS

Param Type Description
seekTime number Time (in seconds) to seek to.
displayImmediately boolean Specifies whether to update to and display target frame immediately.

holoVideoObjectThreeJS.play()

Starts capture playback if sufficient data has been buffered, or resumes paused playback.

Kind: instance method of HoloVideoObjectThreeJS

holoVideoObjectThreeJS.close()

Stops playback and releases capture-specific resources. A new capture can then be loaded by calling open

Kind: instance method of HoloVideoObjectThreeJS

holoVideoObjectThreeJS.pause()

Pauses playback.

Kind: instance method of HoloVideoObjectThreeJS

holoVideoObjectThreeJS.setLogLevel(level)

Sets verbosity level of log output

Kind: instance method of HoloVideoObjectThreeJS

Param Type Description
level number 0 = errors, 1 = warnings, 2 = info, 3 = debug. Default setting is = 0.

holoVideoObjectThreeJS.setAudioEnabled(enabled)

Enables or disables audio playback. May be called at any time.

Kind: instance method of HoloVideoObjectThreeJS

Param Type Description
enabled boolean Specifies whether audio should be enabled or disabled.

holoVideoObjectThreeJS.audioEnabled()

Returns whether audio playback is currently enabled.

Kind: instance method of HoloVideoObjectThreeJS

holoVideoObjectThreeJS.setAudioVolume(volume)

Sets audio volume.

Kind: instance method of HoloVideoObjectThreeJS

Param Type Description
volume number Value between 0 and 1 specifying volume level.

holoVideoObjectThreeJS.setAutoLooping(loop)

Specifies whether capture should loop automatically. May be called at any time.

Kind: instance method of HoloVideoObjectThreeJS

Param Type
loop boolean

HoloVideoObjectThreeJS~openCallback : function

Kind: inner typedef of HoloVideoObjectThreeJS

Param Type Description
mesh THREE.Mesh THREE.Mesh object that will be populated with capture geometry during playback.
