Click on subtitle and go to associated url

[pivoo]

Hi everyone!
I am sorry, I don't know if I post in correct forum.

I need to develop such module, which will open http link in browser when user click on subtitle.
Subtitles are in .ass format, and the link will be in "name" attribute of subtitle.

With some changes to VLC code I can process mouse actions within my subtitle filter module, but I can't understand how can I pass custom information from libass codec module to my filter.
I need to pass some array of structures which will contain coordinates of subtitle region, it's showing time and associated http link.
But I can see that it is only subpicture_t structures returns from libass, in which I don't know how to put needed information.

Could you advise me something?

You can use variables and callbacks for this.
