v1.5.0

Summary

HLS.js v1.5.0 includes playback and API enhancements that support HLS assets containing multiple codec variants, HDR video variants, and multi-channel audio renditions. Support for MediaCapabilities and ManagedMediaSource has also been adopted.

Media segment codec parsing is available for direct playback of media playlists as well as proper setup of MediaSource buffers for AV1, HEVC, HEVC with DolbyVision, AVC, AC3, EC3, Apple Lossless (ALAC), AAC, FLAC and Opus.

MediaCapabilities decodeInfo checks are performed after the initial start before switching to UHD, HDR, and Multi-channel audio options.

Note that auto-switching between codec families is not supported. HLS.js will attempt to start on the most efficient supported codec set available within the initial bandwidth estimate range (up to 500kbps). However, switching between variants with incompatible codecs requires manual intervention by the user or application. Constraining playback to compatible codecs maintains maximum compatibility and stable playback. changeType is used when necessary but avoided for auto-switching because it is not always stable or smooth between all combinations or on all platforms.

ManagedMediaSource support adds the ability to run HLS.js on iOS 17.1 and up. HLS.js in Safari on iOS, iPadOS, and MacOS leverages ManagedMediaSource to start and stop streaming for power-efficient use of wireless connections.

Changes Since The Last Release

v1.4.14...v1.5.0

API Enhancements

  • Named exports for all classes and enums are available in ESM output (#5930) @robwalch
  • Rendition selection enhancements (#5704)
    • HLS.js will no longer start on the first variant (hls.firstLevel) or any variant of a preferred codec if its BANDWIDTH exceeds abrEwmaDefaultEstimateMax
    • Added hls.firstAutoLevel getter, used internally to get the starting level index
      hls.levels are sorted on height, frame rate, preferred codec, and video-range to infer order by quality. Height-first sorting allows cap-level-lontroller to set a max quality index at the maximum allowed resolution
    • Added getters for all audio tracks and all subtitle tracks: hls.allAudioTracks and hls.allSubtitleTracks
  • API enhancements for audio and subtitle selection (#5978)
    • hls.setAudioOption() and config.audioPreference have been added to simplify audio selection based on user preferences and playback settings
    • hls.setSubtitleOption() and config.subtitlePreference have been added to simplify subtitle selection based on user preferences and playback settings. Only subtitle media options (hls.allSubtitleTracks) are subject to selection criteria. Captions are assigned a TextTrack or emitted through events when native rendering is disabled.
  • config.videoPreference.preferHDR and preferHDR have been added to override the default SDR/HDR selection behavior
  • Base initial bandwidth estimate on first level bitrate (#5649)
    • Added setter for bandwidthEstimate that resets estimator to a new starting value
  • Initial selection and level filtering based on preferred codecs and MediaCapabilities (#5704)
    • Added config.useMediaCapabilities (defaults to true)
    • Set config.useMediaCapabilities to false to disable the use of MediaCapabilities.decodingInfo
  • isSupported() has been expanded to test alternate baseline codecs (#6006)
    • Added isMSESupported(), a subroutine of isSupported(), checks for MediaSource API without isTypeSupported checks.
    • Added getMediaSource(), which returns the preferred MSE interface or undefined when unavailable
    • Added named exports for isSupported, isMSESupported, and getMediaSource
  • Fire STEERING_MANIFEST_LOADED event when loading a Content Steering Manifest (#5417) @guillemcabrera
  • Added config flag for maximum front buffer frontBufferFlushThreshold (#5761) @iamboorrito
  • Implement event for maxAutoLevel change (#5763) @robwalch
  • Specify custom shouldRetry predicate in retryConfig (#5658) @PavelFomin90 (completed in #5762)
  • Default estimate enhancements (#5649) @robwalch
    • Added config.abrEwmaDefaultEstimateMax option, which limits how high the initial default value may be adjusted
      Separate peak and average bitrates of Level objects
  • Level properties
    • Level.bitrate uses variant BANDWIDTH (required peak bitrate) before falling back to optional AVERAGE-BANDWIDTH.
    • Level.averageBitrate returns parsed AVERAGE-BANDWIDTH. Falls back to runtime average Level.realBitrate (which is only set when config.abrMaxWithRealBitrate is enabled) and finally Level.bitrate (BANDWIDTH).
    • Added Level.frameRate returns parsed FRAME-RATE number or 0.
    • Added Level.codecs returns parsed CODECS or empty string.
    • Added Level.score returns parsed SCORE number or 0.
  • Added config option preferManagedMediaSource. Set it to false to use MediaSource rather than ManagedMediaSource on platforms with both.
  • Extended cmcd config option with cmcd.includeKeys. Takes an array of CMCD keys to include in client requests. (#5903) @littlespex
