class SimplePacketQueueProducerStage

Defined at line 29 of file ../../src/media/audio/services/mixer/mix/simple_packet_queue_producer_stage.h

A ProducerStage driven by a packet queue. This is a "simple" producer because it does not handle

Start or Stop commands. This is intended to be embedded within a ProducerStage, but can also be

used in isolation in tests.
