Would it be better to check if max_duration == AV_NOPTS_VALUE instead of the
else on the format_context duration. At one point I think ogg files had a
duration on the streams but not on the format_context. 

   // Good to go: set the duration and notify we're done initializing.
   host()->SetDuration(max_duration);
   callback->Run();
