Parses media manifests and handles manifest updates.
Given a URI where the initial manifest is found, a parser will request the
manifest, parse it, and return the resulting Manifest object.
If the manifest requires updates (e.g. for live media), the parser will use
background timers to update the same Manifest object.

Methods
(export) configure(config)
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 | Description |
---|---|---|
config |
shakaExtern.ManifestConfiguration |
- Source:
(export) 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 | |
expiration |
number |
- Source:
(export) start(uri, playerInterface) → (non-null) {Promise.<shakaExtern.Manifest>}
Parses the given manifest data into a Manifest object and starts any
background timers that are needed. This will only be called once.
Parameters:
Name | Type | Description |
---|---|---|
uri |
string | The URI of the manifest. |
playerInterface |
shakaExtern.ManifestParser.PlayerInterface | Contains the interface to the Player. |
- Source:
Returns:
- Type
- Promise.<shakaExtern.Manifest>
(export) stop() → (non-null) {Promise}
Stops any background timers and frees any objects held by this instance.
This will only be called after a successful call to start. This will only
be called once.
- Source:
Returns:
- Type
- Promise
(export) 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 will be called with 'new'.
This function is registered with shaka.media.ManifestParser to create parser
instances.
Type:
- function(new:shakaExtern.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:
- {networkingEngine: !shaka.net.NetworkingEngine, filterNewPeriod: function(shakaExtern.Period), filterAllPeriods: function(!Array.<!shakaExtern.Period>), onTimelineRegionAdded: function(shakaExtern.TimelineRegionInfo), onEvent: function(!Event), onError: function(!shaka.util.Error)}
Properties:
Name | Type | Description |
---|---|---|
networkingEngine |
shaka.net.NetworkingEngine | The networking engine to use for network requests. |
filterNewPeriod |
function | Should be called on a new Period so that it can be filtered. |
filterAllPeriods |
function | Should be called on all Periods so that they can be filtered. |
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. |
