Is there any way to get current caption's text from video tag using Video.js?

Question

I want to get current subtitles' text during playing a video (and than implement own subtitles block (ie to hide original) and also use the information in a few different ways). Currently I use videojs for my player. Is there any way to get current caption's string from it?

Answer 1

This code gets the current cue and put into the <span> element

(function(){

    var video = document.querySelector('video');
    var span = document.querySelector('span');

    if (!video.textTracks) return;

    var track = video.textTracks[0];
    track.mode = 'hidden';

    track.oncuechange = function(e) {

        var cue = this.activeCues[0];
        if (cue) {
            span.innerHTML = '';
            span.appendChild(cue.getCueAsHTML());
        }

    };
})()

Answer 2

Yes, you can add a cuechange event listener when your video loads. This can get you the current track's caption text. Here is my working example using videojs.

Answer 3

var videoElement = document.querySelector("video");
var textTracks = videoElement.textTracks; 
var textTrack = textTracks[0]; 
var kind = textTrack.kind // e.g. "subtitles"
var mode = textTrack.mode

Use the HTML5 Video API to get the current source, the split the src using / and . to get the name.

Solution:

    videojs("example_video_1").ready(function() {
        myvideo = this;

        var aTextTrack =  this.textTracks()[0];
        aTextTrack.on('loaded', function() {
            console.log('here it is');
            cues = aTextTrack.cues();   //subtitles content is here
            console.log('Ready State', aTextTrack.readyState()) 
            console.log('Cues', cues);
        });

        //this method call triggers the subtitles to be loaded and loaded trigger
        aTextTrack.show();
    });
