* VoEBase contains only stub methods (until downstream code is updated). * voe::Channel and ChannelProxy classes remain, but are now created internally to the streams. As a result, internal::Audio[Receive|Send]Stream can have a ChannelProxy injected for testing. * Stream classes share Call::module_process_thread_ for their RtpRtcp modules, rather than using a separate thread shared only among audio streams. * voe::Channel instances use Call::worker_queue_ for encoding packets, rather than having a separate queue for audio (send) streams.
