You can then take one caption and create a VTTCue to add to a TextTrack with Video.js APIs 1Ĭonst track = player.

Typed array containing video and caption dataĬonst timescales = mp4probe.timescale(data) Ĭonst videoTrackIds = TrackIds(data) Ĭalling captionParser.parse with data containing CEA-608 captions will result in an object with this structure: 1 Import mp4probe from 'mux.js/lib/mp4/probe'

For this reason, the video trackIds and timescales defined in the init segment should be passed into the CaptionParser. When working with HLS and MPEG-DASH with fmp4 segments, it’s likely that not all the information needed to parse out captions are included in the media segments themselves, and metadata from the init segment needs to be passed to the CaptionParser.

initalize the CaptionParser to ensure that it is ready for data Import from 'mux.js/lib/mp4' Ĭonst captionParser = new CaptionParser() Caption Parsing is handled by the mux.js library and interacts with VHS to feed parsed captions back to Video.js.
