   That is not true - you have either dual core CPU or 4-core without hyperthreading if you get only 1 thread for decoding. The idea here is to limit the number of OpenMP threads to the number of physical cores - 1, so that the scheduler is not starved for resources, even if preprocess_threads variable is higher than that. We could lift that restriction and rely on user to provide the option that makes sense.
