[question] would be possible to add a subtitle feature

[SDUBZ]

would you be able to add a caption feature or do you know of a addon for the player?

I have thought about it, but I don't have a good way to seamlessly supports it yet.

The main problem is how to load it, since we can't dynamically create a URL to load from outside and the only way may be bundle the subtitles with the world, hardcoded URLs or user manually input the (direct link) URL, these ways all not very ideal I think.
And the second problem is what format should it supports. If the format too complex, it will make the parser heavy.

You might give my project a try. I do have some changes on the dev branch that disconnect it from USharpVideo as a dependency that is yet to be released...

Right now I'm focusing on completely rewriting it into a separate project that will be way easier to integrate with all video players through stable API.
