public

alignPDT(details: LevelDetails, lastDetails: LevelDetails)

Computes the PTS of a new level's fragments using the difference in Program Date Time from the last level.
public

alignStream(lastFrag: undefined, lastLevel: undefined, details: LevelDetails)

Using the parameters of the last level, this function computes PTS' of the new fragments so that they form a contiguous stream with the last fragments. The PTS of a fragment lets Hls.js know where it fits into a stream - by knowing every PTS, we know which fragment to download at any given time. PTS is normally computed when the fragment is demuxed, so taking this step saves us time and an extra download.

public alignMediaPlaylistByPDT(details: LevelDetails, refDetails: LevelDetails) source 

import {alignMediaPlaylistByPDT} from 'hls.js/src/utils/discontinuities.ts'

Ensures appropriate time-alignment between renditions based on PDT. Unlike alignPDT, which adjusts the timeline based on the delta between PDTs of the 0th fragment of two playlists/LevelDetails, this function assumes the timelines represented in refDetails are accurate, including the PDTs, and uses the "wallclock"/PDT timeline as a cross-reference to details, adjusting the presentation times/timelines of details accordingly. Given the asynchronous nature of fetches and initial loads of live main and audio/subtitle tracks, the primary purpose of this function is to ensure the "local timelines" of audio/subtitle tracks are aligned to the main/video timeline, using PDT as the cross-reference/"anchor" that should be consistent across playlists, per the HLS spec.

NameTypeAttributeDescription
details LevelDetails
refDetails LevelDetails
