[Live-devel] problems moving to asynchronous rtsp interface

You need to abandon this line of thinking.  The asynchronous "RTSPClient" interface has been in place - and in use by lots of people - for a year and a half now.  It's not going to change (at least, not significantly).

Each response handler callback routine gets a pointer (as its first parameter).  It's not a "void*"; instead, it's a "RTSPClient*".  But this one pointer is enough to give you all the state you need.  Having a second (or third) extra "void*" pointer would be extraneous and unnecessary.  If you want to carry around a pointer to some extra state, then you can just do so using a field in your "RTSPClient" subclass.
