Parameters:
Name Type Description
time number The time in seconds.
Source:

(export) find(time) → (nullable) {number}

Finds the position of the segment for the given time, in seconds, relative to the start of a particular Period. Returns the position of the segment with the largest end time if more than one segment is known for the given time.
Parameters:
Name Type Description
time number

Returns:
The position of the segment, or null if the position of the segment could not be determined.
Type
number

fit(periodDurationnullable)

Expands the first SegmentReference so it begins at the start of its Period if it already begins close to the start of its Period. Also expands or contracts the last SegmentReference so it ends at the end of its Period. Do not call on the last period of a live presentation (unknown duration). It is okay to call on the other periods of a live presentation, where the duration is known and another period has been added.
Parameters:
Name Type Attributes Description
periodDuration number <nullable>
Source:

(export) get(position) → {shaka.media.SegmentReference}

Gets the SegmentReference for the segment at the given position.
Parameters:
Name Type Description
position number The position of the segment.
Source:
Returns:
The SegmentReference, or null if no such SegmentReference exists.
Type

Parameters:
Name Type Description
references Array.<!shaka.media.SegmentReference> The list of SegmentReferences, which must be sorted first by their start times (ascending) and second by their end times (ascending). They must have continuous, increasing positions.
Source:

(export) offset(offset)

Offset all segment references by a fixed amount.
Parameters:
Name Type Description
offset number The amount to add to each segment's start and end times.
