Everyone, Your input on this is requested. Issue-152 is asking for change proposals for a solution for media resources that have more than just one audio and one video track associated with them. The spec addresses this need for text tracks such as captions and subtitles only [1]. But we haven't solved this problem for additional audio and video tracks such as audio descriptions, sign language video, and dubbed audio tracks. In the accessibility task force we have discussed different options over the last months. However, the number of people that provide technical input on issues related to media in the TF is fairly limited, so we have decided to use the available time until a change proposal for issue-152 is due (21st February [2]) to open the discussion to the larger HTML working group with the hope of hearing more opinions. Past accessibility task force discussions [3][4] have exposed a number of possible markup/API solutions. The different approaches are listed at http://www.w3.org/WAI/PF/HTML/wiki/Media_Multitrack_Media_API . This may be an incomplete list, but it's a start. If you have any better ideas, do speak up. Which approach do people favor and why? Cheers, Silvia.
