Hi Silvia,

If <video poster> provided no content, <video poster> would not exist.
What this all boils down to is the ability to access content. Philip's
prevailing change proposal stated "we provide the possibility of
indicating an image which is more indicative of the content".  [1]

HTML5 should have a mechanism to provide that indication to people
with disabilities. Currently it does not. John offered the group a
proposal regarding how HTML could natively offer a mechanism to
equitably obtain the same content currently in <video poster> to
people with disabilities but it was rejected.

I hope that everyone in the HTML Working Group comprehends the big
picture here. Increasingly HTML5 is relying on ARIA to provide for
HTML5's accessibility failings.

As Everett Zufelt mentioned a while back on the HTML5 Doctor, "The
longer the broader development community, such as the HTMLWG, ignores
accessibility, or thinks that others like the PFWG / WAI will take
care of it for them, the longer we will need technologies like ARIA to
fill in the blanks." [2]

Numbers alone must not be the driving factor for technology decisions.
The 80/20 rule does not apply. What Al Gilman said a few years ago is
still true today. [3]

Best Regards,
