== Current Design and Behavior of non-adaptive streams ==

With current native video, Necko buffers the data until it is safe to start playing. nsMediaChannelStream downloads data via HTTP and puts that data in an nsMediaCache. nsMediaCache intrun makes this data available to decoder threads via read() and seek() APIs. The decoders then read the dtaa and enqueue it in A/V queues.

Two initial ideas were suggested by Rob O'Callahan:

# One nsMediaDASHStream class is created which manages the monitoring of local capabilities/load and adapts download by switching streams as necessary. Then one nsMediaCache provides data to a single nsWebMDecoder.

# One nsMediaDASHStream as before, but with multiple nsWebMDecoders, one for each encoded stream available on the server. Only one nsWebMDecoder would be used at a time.
