Parameters:
Name Type Description
uri string
Source:

configure(config, isPreloadFnopt)

Called by the Player to provide an updated configuration any time the configuration changes. Will be called at least once before start().
Parameters:
Name Type Attributes Description
config shaka.extern.ManifestConfiguration
isPreloadFn function <optional>
Source:

onExpirationUpdated(sessionId, expiration)

Tells the parser that the expiration time of an EME session has changed. Implementing this is optional.
Parameters:
Name Type Description
sessionId string

variant shaka.extern.Variant
Source:

setMediaElement(mediaElement)

Set media element.
Parameters:
Name Type Description
mediaElement HTMLMediaElement
Source:

start(uri, playerInterface) → {Promise.<shaka.extern.Manifest>}

Initialize and start the parser. When |start| resolves, it should return the initial version of the manifest. |start| will only be called once. If |stop| is called while |start| is pending, |start| should reject.
Parameters:
Name Type Description
uri string The URI of the manifest.
playerInterface shaka.extern.ManifestParser.PlayerInterface The player interface contains the callbacks and members that the parser can use to communicate with the player and outside world.
Source:
Returns:
Type
Promise.<shaka.extern.Manifest>

stop() → {Promise}

Tell the parser that it must stop and free all internal resources as soon as possible. Only once all internal resources are stopped and freed will the promise resolve. Once stopped a parser will not be started again. The parser should support having |stop| called multiple times and the promise should always resolve.
Source:
Returns:
Type
Promise

update()

Tells the parser to do a manual manifest update. Implementing this is optional. This is only called when 'emsg' boxes are present.

Type Definitions

Factory

A factory for creating the manifest parser. This function is registered with shaka.media.ManifestParser to create parser instances.
Type:
  • function():!shaka.extern.ManifestParser
Source:

PlayerInterface

Defines the interface of the Player to the manifest parser. This defines fields and callback methods that the parser will use to interact with the Player. The callback methods do not need to be called as member functions (i.e. they can be called as "free" functions).
Type:
Properties:
Name Type Description
networkingEngine shaka.net.NetworkingEngine The networking engine to use for network requests.
filter function Should be called when new variants or text streams are added to the Manifest. Note that this operation is asynchronous.
makeTextStreamsForClosedCaptions function A callback that adds text streams to represent the closed captions of the video streams in the Manifest. Should be called whenever new video streams are added to the Manifest.
onTimelineRegionAdded function Should be called when a new timeline region is added.
onEvent function Should be called to raise events.
onError function Should be called when an error occurs.
isLowLatencyMode function Return true if low latency streaming mode is enabled.
isAutoLowLatencyMode function Return true if auto low latency streaming mode is enabled.
enableLowLatencyMode function Enable low latency streaming mode.
updateDuration function Update the presentation duration based on PresentationTimeline.
newDrmInfo function Inform the player of new DRM info that needs to be processed for the given stream.
onManifestUpdated function Should be called when the manifest is updated.
