Currently the method remotemediasourceproxy::buffered() isn't implemented (it was removed in bug 253560 as its implementation was completely broken). It is necessary for the MockMediaPlayerMediaSource to have access to the MediaSource buffered range so that it can control how time advances during playback. We need to add methods that will allow to keep the MediaSource and RemoteMediaSourceProxy buffered range in sync.
