 > @elioxia I'm kind of debating which way to go for this at the
 moment...if we have a dedicated thread for an SDL device then it prohibits
 us from (for instance) calling SDL_Init in another thread if we want 2
 devices present at the same time, doesn't it?  I guess we could live with
 "at most 1" device (and don't use SDL for anything else in your app!) or
 is there another way?

 sdl1.2 requires the presence of a single window per application. So there
 is no way to create different SDL devices (I guess you could have video
 and audio in different devices, but that would be quite pointless, and

 Or use sdl2 which should support that (well at least different windows per
 application). Anyway this seems unrelated to this ticket.
