Yeah, though IMHO the whole option printing stuff is ugly.
If some application had only warning level messages enabled it wouldn't get any printout.
And those printouts are associated with a NULL context, so ffplay does such hacks as redirecting the av_log callback.
Probably the functions should have been designed to take a print callback function pointer instead, and ffplay would just pass printf in directly for example (though something more flexible might make more sense, at least a user defined pointer. Or maybe it should just return a malloc'd pointer with the string...).
