I'm not sure I understand the problem you are having. The
MediaSource.readyState being "ended" should not effect seekability. You
should be able to seek whether the readyState is "open" or "ended". Why do
you think there needs to be a transition from "ended" to "open"? I think
this transition should only happen if the application appends more data,
which is what the current spec says should happen.

Please provide more details so I can better understand the issue you are
having.
