LibZL API

LibZL is a library used for interacting with ZeroLight content streams. LibZL allows you to more finely control what occurs in the stream by providing an API which allows you to augment the capabilities of the stream.

Usage​

LibZL itself consists of an API factory, allowing you to choose which API you wish to use. There are at this time two APIs - zlbolt and direct2D. The zlbolt API provides control over a 2D or 3D stream, while direct2D instead provides you with the capability to generate a series of images via a set of frame configurations.

This document has a few basic usage examples and explanations of the public APIs provided for working with the ZeroLight content streams.

LibZL can be invoked to produce the zlbolt API in the following way:

const libzl = new LibZL();
const zlbolt = libzl.zlbolt(projectName, mainDomain);

and similarly the direct2d API can be called with libzl.direct2D(mainDomain).

These return promises which you can resolve to get the API. Earlier workflows often involved overriding event functions after the API was defined in the browser. This method has been succeeded by the promises form and a newer event listener method to call multiple functions at the time of the event.

Using Zlbolt​

Created using libzl.zlbolt(projectName, mainDomain);, this exposes the zlbolt API. This is typically used via listening to event functions, such as onModeChange, to extend the stream's functionality. For a full list of events see the Events and Listeners section.

Note that some events may be overridden instead of adding a listener. This is a legacy feature and isn't recommended. Some events may not support that method of calling.

Minimal Usage Example​

This is a minimal example for a fictitious car manufacturer, Antarctic Motors, connecting to a stream of the 2019 Snowmobile.

const libzl = new LibZL();
const connectionParameters = {
	customer: 'antarctic',
	environment: 'live',
	protocol: 'https',
	region: 'eu-west-1'
};

const car = {
	manufacturer: 'antarctic',
	model: 'snowmobile',
	year: 2019
};

// the element ID of the container to put the stream in
const parent = 'myStreamContainer';
const options = {connectionParameters, parent, car};

const projectName = 'antarctic';
libzl.zlbolt(projectName, 'zlthunder.net')
	.then(function(api) {
		// Adding to the global namespace
		zlbolt = window.zlbolt = api;

		// Adding event listeners for things we're interested in
		zlbolt.addEventListener('error', function(error) {
			console.log('zlbolt had an error: ', error);
		});
		zlbolt.addEventListener('streamReady', function() {
			console.log('The stream is ready!');
		});

		//Connecting to the stream
		//    - options contains parent DOM element name to attach to
		zlbolt.connect(options);
	});

Events and Listeners​

To extend the stream's functionality there are a set of event functions which may be overridden, or listened to.

Events are hooked into via addEventListener instead. These include a larger range of events, and are intended to be used for page events. These can be either listened to or overridden entirely (not recommended). To override the event function entirely, capitalise the event name and prefix with on. Please note that this is a legacy feature and some event types may not support this.

Valid events, and their arguments provided, to listen for include:

  • onError - fired when zlbolt encounters an error
  • onReconnect - fired upon attempting to reconnect to a previous stream
  • onStreamReady - fired upon the stream being ready
  • onReadyToStream - fired upon the stream being primed for streaming
  • onStreamDisconnect - fired upon the stream disconnecting
  • streamReady
  • streamMetricsUpdated - single argument an object with streamMetrics in
  • streamDisconnect - single argument a string with the reason for disconnecting
  • streamConnectFailed - single argument, object - { outputType: string (e.g.'WebRTCStreamOutput'), error: Error }
  • allStreamAttemptsFailed - single argument, object - { instanceIp: string, ssl: boolean, errors: { [outputType: string]: Error } }
  • streamWillDowngrade
  • streamWillUpgrade
  • streamDidDowngrade

  • prcodesChanged - single argument object with the PR code differences
  • cameraChanged
  • cameraMoved - single argument object with duration and measurements
  • 2DODAvailable - a single argument returning the 2D api - not recommended to use directly
  • 2DFrameRequest - a pair of arguments representing any errors and the returned frame object
  • all2DFramesReady
  • 2DFrameTransition - a pair of arguments representing any errors and the returned frame object
  • 2DProgressBarChanges - a pair of arguments representing any errors, and a progress object
  • adoptionInformation - a single argument representing very rough adoption estimates
  • error - single argument an object representing the error
  • reconnect
  • maximumConnectionRetries
  • optionsReconcile
  • optionsChange
  • mouseDown - a single argument object representing the click position
  • mouseUp - a single argument object representing the mouse position
  • cameraSequenceStart - a single argument string with the name of the camera sequence
  • cameraSequenceEnd - a single argument string with the name of the camera sequence
  • modeChange - a pair of arguments with the mode and a string status (pending, success, or error)
  • ping - Raised when the 3D stream receives an instance ping result. ({ success: true, time: number} | { success: false, count: number })
  • streamElementsChanged - Raised when the stream containers elements are changed.
  • bandwidthAssessed - a single argument with the bandwidth results
  • connectionStatusChanged - a pair of arguments with the previous status and changed status in connection flow ({status, newStatus})
  • makeFrameConfig - a triple of arguments with the made frame config, the base config that was supplied, and the string context that it was called in
  • fetchFramesRequest - a triple of arguments with the frameConfigs, the generation options, and the string context that it was called in

There are a few extra that require richDataStreamConfig.enableCompletionEvents to be set in options

  • environmentChange - (status, [env name]) string arguments e.g. ("started", undefined) ("completed", "Antarctica")
  • animationChange - animationsObject object argument with key animation names and state value
  • cameraChange - cameraName string argument with the camera name
  • prcodesChange - prcodes string argument with the current prcodes once they change

Debugging and Profiling​

The libZL Profiler​

LibZL profiler could be enabled for a single session by the user or on a per-service basis in Central Config.

Single session

Use one of the below methods to enable profiler:

  • URL parameter - add zlLoggerTimer=1 to your URL parameters
  • Local storage - add zlLoggerTimer=1 to the browser's local storage

Central config Add to Central Config file property:

{
	"debug": {
		"profile": true
	}
}

Profile summary will be available using the libZL method:

LibZL.zlLoggerTimerSummary()

Using Direct2D​

Created using libzl.direct2D(mainDomain), this exposes the 2d API. This is slightly different as it needs an intermediate connection step handling the options. This API is used to obtain images of the cars by specifying frame configurations, which is useful for e.g. thumbnail images or preview shots.

A returned frame has a variety of promises as properties, which resolve at different times. See the direct2D class for more details.

Minimal Usage Example​

This is a minimal example for a fictitious car manufacturer, Antarctic Motors, connecting to a stream of the 2019 Snowmobile.

const libzl = new LibZL();

const connectionParameters = {
	customer: 'antarctic',
	environment: 'live',
	protocol: 'https',
	region: 'eu-west-1'
};

const car = {
	manufacturer: 'antarctic',
	model: 'snowmobile',
	year: 2019
};

const options = {connectionParameters, car};

libzl.direct2D('zlthunder.net')
	.then(api => api.connect(options))
	.then(api => {

		// Create a frame config from a partial one.
		let frame = api.makeFrameConfig({
			car: '{manufacturer} {model} {year}',
			environment: '{environment}',
			camera: {
				specification: 'named',
				name: '{camera}'
			},
			size: [800, 600]
		});

		// Request the frames. Pass larger array for more frames.
		let frameRequest = api.fetchFrames([frame]);

		// Add listener to the ready promise of each frame.
		Object.keys(frameRequest.frames).forEach(function(filename) {
			let frame = frameRequest.frames[filename];

			// When frame is ready, insert it into DOM.
			frame.readyPromise.then(function() {
					$('<img />').attr('src', frame.url).appendTo($('body'));
			});
		});
	});
