And I forgot to add that when using GstAudioAggregator you should not
override GstAggregator::aggregate() but instead GstAudioAggregator::cre
ate_output_buffer() and GstAudioAggregator::aggregate_one_buffer().

If you override the former then all the processing logic of GstAudioAgg
regator is disabled.
