See discussion on whatwg: http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2011-April/thread.html#31315
Per WebKit contributor meeting discussion:
Ready states:
- error
- unknown
- buffering
Runtime states:
- playing
Media characteristics:
- has-closed-captioning
- has-audio
- has-video
- has-duration
Example of how to use for default UA stylesheets:
- Browser A always wants to display a closed captioning button, but have it disabled when there are no closed captioning. Default style for video:has-closed-captioning is disabled.
- Browser B only wants to display a closed captioning button when present. Default style for video:has-closed-captioning is display:none

Looks like this will be a good addition. If no one is working on this I will try to submit a patch.
Is this a final list of media pseudo classes that we have planned to add? Also one more thing, what does this "unknown" state mean?

Eric, do you remember what "unknown" meant? I lost track of this :)

I don't recall exactly, maybe for an element with preload=none?

Maybe. Arun, I would recommend starting with a small set of pseudo-classes and iterating on that.

Ok, Thanks. I will start with small set. May be, media characteristics pseudo classes in first patch in separate bug.

:volume-locked
These are in addition to these ones which already existed:
:playing
:paused
