I think it's better to try things out and measure than to make assumptions
about performance. The relative cost of those transitions will depend very
much on the implementation, and decisions about buffer sizing etc.

Also, devices have multiple CPU cores now. My ProcessedMediaStream
implementation spreads the processing for different streams across all
available cores. It's especially hard to predict performance in that kind
of configuration.
