It appears that advisory text against doing this will likely suffice - there does not appear to be any actual implementation of this today. In conversation with David Dorwin at TPAC, I will return to the accessibility Task force and we will supply draft author advisory text that can be added to the specification. David if you want to file a bug, I can respond to that, or I can respond via this bug - your call. > > > (In reply to David Dorwin from comment #5) > > > EME assumes encryption is on blocks within the media container. > > > > While this may be the assumption and what every implements in practice, is > > there actually something in the spec that prohibits the encryption being a > > wrapper around the media container?

A number of assumptions were not clearly documented, and we've > been trying to address those. I believe this is out of scope for accessibility concerns. I will leave it to others to file a bug and respond -- You are receiving this mail because: You are on the CC list for the bug.
