Methods

checkSegmentIndexRangeSupport_(context, initSegmentReference)

Check if this type of segment index is supported. This allows for immediate errors during parsing, as opposed to an async error from createSegmentIndex(). Also checks for a valid byte range, which is not required for callers from SegmentTemplate.
Parameters:
Name Type Description
context shaka.dash.DashParser.Context
initSegmentReference shaka.media.InitSegmentReference
Source:

checkSegmentIndexSupport(context, initSegmentReference)

Check if this type of segment index is supported. This allows for immediate errors during parsing, as opposed to an async error from createSegmentIndex().
Parameters:
Name Type Description
context shaka.dash.DashParser.Context
initSegmentReference shaka.media.InitSegmentReference
Source:

computeIndexRange_(context) → {?{start: number, end: number}}

Compute the byte range of the segment index from the container.
Parameters:
Name Type Description
context shaka.dash.DashParser.Context
Source:
Returns:
Type
?{start: number, end: number}

computeIndexUris_(context) → {Array.<string>}

Compute the URIs of the segment index from the container.
Parameters:
Name Type Description
context shaka.dash.DashParser.Context
Source:
Returns:
Type
Array.<string>

createInitSegment(context, callback) → {shaka.media.InitSegmentReference}

Creates an init segment reference from a Context object.
Parameters:
Name Type Description
context shaka.dash.DashParser.Context
callback function(?shaka.dash.DashParser.InheritanceFrame):Element
Source:
Returns:
Type
shaka.media.InitSegmentReference

createQualityInfo(contextnon-null) → {shaka.extern.MediaQualityInfo}

Create a MediaQualityInfo object from a Context object.
Parameters:
Name Type Description
context shaka.dash.DashParser.Context
Source:
Returns:
Type
shaka.extern.MediaQualityInfo

createStreamInfo(context, requestSegment) → {shaka.dash.DashParser.StreamInfo}

Creates a new StreamInfo object.
Parameters:
Name Type Description
context shaka.dash.DashParser.Context
requestSegment shaka.dash.DashParser.RequestSegmentCallback
Source:
Returns:
Type
shaka.dash.DashParser.StreamInfo

fromInheritance_(framenullable) → {Element}

Parameters:
Name Type Attributes Description
frame shaka.dash.DashParser.InheritanceFrame <nullable>
Source:
Returns:
Type
Element

generateSegmentIndex_(context, requestSegment, initSegmentReference, scaledPresentationTimeOffset) → {Promise.<shaka.media.SegmentIndex>}

Generate a SegmentIndex from a Context object.
Parameters:

generateSegmentIndexFromUris(context, requestSegment, initSegmentReference, urisnon-null, startByte, endBytenullable, scaledPresentationTimeOffset) → {Promise.<shaka.media.SegmentIndex>}
