How to add subtitle/caption tracks to media player?

Hi everyone,
I’m tryin’ to make a soft subtitle system for my game.
I’ve already used the Localization Dashbord to locate all Texts in my game but now I need to add subtitles to my videos.

I’ve already made a .srt file in the video’s folder and I can show subtitles using VLC media player. Anyway I can’t use them in Unreal.

I’m using the Unreal Media Player in which I see an option saying “caption” or “subtitles” under the playback options. Anyway the engine doesn’t find any track there.

So how can I add caption or subtitle tracks to my videos?

Thank you.

did you find a way to do this?
