video accessibility work

Silvia Pfeiffer
Hi all,

I just wanted to introduce myself briefly and the new work-item I'm doing.

My name is Silvia Pfeiffer, I am from Sydney, Australia, and Mozilla
is supporting me to do some video accessibility work for the upcoming
HTML5 <video> and <audio> elements - so we can all better use these
multimedia files. I have not previously worked with Mozilla and am
very happy about this challenge. I have however, worked with Xiph and
timed text codecs for almost 10 years and have previously done some
work on automated captioning using speech recognition.

Since I'd like to get as much active contribution from the Xiph
community as possible and not spam any other mailing lists, I have set
up a separate video accessibility mailing list at Xiph: .

If you feel strongly about audio/video accessibility and can
contribute technical help - in particular from a disabled person's
viewpoint - I would really like you to join!
