Hi Milo:
Unfortunately, not.
It is based on the HTML5 video tag, and it doesn't really support
captioning (yet?). I know that Mozilla has some proposal for it, but
nothing real (if there is something already working, I would really
like to take a look at it).
http://www.w3.org/TR/html5/video.html does indeed state the following:
"In particular, this content is not fallback content intended to
address accessibility concerns. To make video content accessible to
the blind, deaf, and those with other physical or cognitive
disabilities, authors are expected to provide alternative media streams
and/or to embed accessibility aids (such as caption or subtitle
tracks) into their media streams."
Like you, however, I recall Mozilla working on a proposal to improve
this situation. I'm CC'ing David Bolter on this e-mail -- he's with
Mozilla and can hopefully tell us more about the Mozilla proposal.
Willie, do you think the absence of CC or subtitles is a real blocker
to the introduction of small video in the help?
With my accessibility hat on - all developers need to design for
accessibility. Just as i18n is a consideration you make every day, you
need to do the same for a11y. Planning to retrofit it in as an
afterthought results in one of two things: 1) it never gets done or 2)
it tends to be more costly than if you did it right from the beginning.
And, by all means, documentation is one of the most crucial aspects to
learning. By creating inaccessible documentation, you immediately
create a barrier to entry.
