That would work, but would make it a bit uglier at the call site.

I'm planning to move these functions to rtspenc/dec.c later, and then they 
will have proper declarations in rtsp.h. I fixed the issue for now by 
adding a stub declaration in an #else branch, but all of that uglyness 
will be removed once I move them.
