stnishimura has just created a new issue for 
https://github.com/w3c/media-source:

== Needs event to notify when sourceBuffer needs more data ==
For a device like TV that has limited size of sourceBuffer and low 
processing power, it is important to be able to manage buffer with 
minimum resource consumed as possible, i.e. without using extra 
setTimeout or timeupdate event handling. "2.4.4 SourceBuffer 
Monitoring" specifies that ‘canplay’ event fires when readyState 
changes from HAVE_FUTURE_DATA to HAVE_ENOUGH_DATA but no event would 
fire when an opposite change occurs, while it is important for 
application (dash.js) to know when is the right time to put next 
segment.

This is one of the issues raised in the Web and TV IG meeting at TPAC 
2015 by Hybridcast group.
