Default video subtitle

[thumaman]

Hi, i was wondering what is the purpose of setting a subtitle value to default and what it should do.

I am dealing with devices with disabled input so i would like to play a certain subtitle at the start of the video without having to select it manually.

I tried setting an english subtitles to default value, hoping that it would display them at the start but no luck. Here is a snippet of my code where is set the default value to true if the subtitle is english:

            // add subtitles to the video

            foreach (var subtitle in subtitleFiles)
            {
                //print subtitle
                Console.WriteLine(subtitle);
                var subtitlePath = subtitle;
                var file = subtitlePath.Split('/').Last();
                var lang = file.Split('.').Skip(1).First();
                var label = lang.ToUpper();
                bool def = lang == "en";
                newVideoSource.Tracks.Add(new VideoTrack(subtitlePath)
                    {
                        Kind = "subtitles",
                        Label = file,
                        Source = subtitlePath,
                        Language = lang,
                        Default = def
                    });

Am I missing something, or what could be the issue?

Thank you for your help.

The purpose of default is to define the track that will show immediately when the video starts. See here https://www.vidstack.io/docs/player/core-concepts/loading#text-track-default

I found the issue on my part, but still when i change the video and set a different subtitle to default they are not displayed (so the default option only works on the first video). I have to look into it.

I also noticed that .srt subtitles do not work, is there an issue on my end? I tried several different files but no luck.

It should work. https://www.vidstack.io/docs/player/core-concepts/loading#text-track-formats

Did you define a track type?

My mistake, i though it would work without defining a type, like it does for .vtt files. It works now that I defined: Type = "srt",
