Do two things: 1. add locking to struct osd_state 2. make struct osd_state opaque While 1. is somewhat simple, 2. is quite horrible. Lots of code accesses lots of osd_state (and osd_object) members. To make sure everything is accessed synchronously, I prefer making osd_state opaque, even if it means adding pretty dumb accessors. All of this is meant to allow running VO in their own threads. Eventually, VOs will request OSD on their own, which means osd_state will be accessed from foreign threads.
