video-dev/hls.js v0.14.0

on GitHub

Version 0.14 adds API features found in the feature/v1.0.0 branch. This is intended to make transitioning to v1.0.0 easier and also provide API parity for A/B testing the current release and next major update of hls.js.

In addition to these features and bug fixes, we've made changes to how our CI versions preview builds which are published to npm to account for pre-releases while maintaining semver precedence. To do this, we have replaced the canary channel with an alpha channel. Previously, if we cut a beta or release candidate like 0.14.0-rc.2 the next commit would generate a canary, using the last release patch+1 - so 0.13.3-canary.5704. That worked following 0.13.2, but after 0.14.0-beta.1, it ignores that we are already heading on to the next minor release. To fix this, we now generate an alpha, using the last tag. So in the case of a prerelease - 0.14.0-rc.2.0.alpha.5718. And for releases we still increment the patch - so following this release you will see CI builds versions like 0.14.1-0.alpha.5720.

Enhancements

• Add CEA-608 captions 4 channel support
  • Adds config options for additional channels captionsTextTrack3Label, captionsTextTrack3LanguageCode, captionsTextTrack4Label, captionsTextTrack4LanguageCode
• Add renderTextTracksNatively config option (defaults to true) which allows for disabling the addition of captions/subtitle TextTracks to the video element for 608/VTT tracks
  • When set to false rather than a new TextTrack being added for captions and subtitles, NON_NATIVE_TEXT_TRACKS_FOUND and CUES_PARSED events are emitted so that the application using hls.js can handle rendering of the track and its cue points.
