is it support subtitles ?

[megasto]

hi, thank you @Lindsay-Needs-Sleep for handling this plugin
I'm just coming to ask if this plugin support subtitle??, trying a lot of tricks to make it work, but still nothing, the subtitle didn't show
my console log for [this.castMedia] :

"tracks":[
{
"trackId"=1,
"type":"VIDEO",
"trackContentType":null,
"trackContentId":"null",
"subtype":'null',
"name":'null',
"language":'null',
"customData":'null'
}
]

code using for

var videoUrl = 'https://cdn.plyr.io/static/demo/View_From_A_Blue_Moon_Trailer-576p.mp4';
var thesub = 'https://cdn.plyr.io/static/demo/View_From_A_Blue_Moon_Trailer-HD.en.vtt';


const englishSubtitle = new chrome.cast.media.Track(1,chrome.cast.media.TrackType.TEXT);
   englishSubtitle.trackContentId =thesub ;
   englishSubtitle.trackContentType = 'text/vtt';
   englishSubtitle.subtype = chrome.cast.media.TextTrackType.SUBTITLES;
   englishSubtitle.name = 'English';
   englishSubtitle.language = 'en-US';
   englishSubtitle.customData = null;
   var tracks = [englishSubtitle];

        var mediaInfo = new chrome.cast.media.MediaInfo(videoUrl);

         /**/ mediaInfo.tracks = tracks;
        mediaInfo.activeTrackIds = [1];
        
      
        this.isCasting = true;
        this.castSession.loadMedia(new chrome.cast.media.LoadRequest(mediaInfo), (media:any)=> {
            // You should see the video playing now!
            // Got media!
            
             this.castMedia = media;
            alert(JSON.stringify(this.castMedia, null, 2));
         
        }, function (err) {
            // Failed (check that the video works in your browser)
           // alert("Failed : check that the video works in your browser")
            alert(JSON.stringify(err, null, 2));
            this.isCasting = false;
           
        });

This was a feature I wanted to test, but I didn't have access to any subtitle tracks (and no general knowledge about how subtitles work / how to generate / etc).

We're probably missing a small piece of code that enables them.

Have you tried on android and ios? (there's a tiny chance that one of them already has the subtitle logic.)

If not, I think this shouldn't be too hard to add.

I don't have to time to get the project to build and test right now, but if you are interested in doing it, I can provide some guidance possibly.

The first step would be confirming that your javascript works on a regular desktop chrome browser. (I'm guessing you have done that already.)

at first, I have doubted this issue may be related to CORS but i think it's excluded now :)

I'm currently on android using ionic framework, did you have any other logic can help??

I'm really intersting to figure out this issue but i'm not have a large experience for something like that due to my limitation

anaway just let me know what do as possible as i can :)

@megasto If you are still looking for this feature (or for any other folks that may come along) I implemented this for Android builds in my forked version of this plugin. https://github.com/pdille/cordova-plugin-chromecast

While it could be refactored slightly, it works for my needs and anyone else is welcome to use it.

Thank you @pdille you are my hero,
I'm using your fork and its working fine for me on Android,
Can you implement the same fix for iOS please ?.
