Client            ->  rialtoClient:     getBufferDelay(web_audio_session)
rialtoClient      ->  rialtoServer:     getBufferDelay(web_audio_session)
rialtoServer      ->  rialtoServer:     Calculate delay_frames
note right
Ideally this would be queried from the GStreamer pipeline, either by directly getting
Directly get the amount of buffered data or calculating it something like this:

  delay = gst_elementqueued_query_durationframes() -+ gstshm_elementqueued_query_positionframes();

This requires some experimentation to see what works. The existing implementation
relies on elapsed time vs position but this will become problemmatic when support
for pause() is required.

rialtoServer      --> rialtoClient:     delay_frames
rialtoClient      --> Client:           delay_frames
