Dear Thierry, All: The HTML-A11Y Task Force has reviewed the WebVTT FPWD specification during our face to face meeting this past Friday 17 April. Minutes of this session are available at: http://www.w3.org/2015/04/17-html-a11y-minutes.html#item01 Our reference document for accessibility requirements is the note track "Media Accessibility User Requirements (MAUR)" available at: http://w3c.github.io/pfwg/media-accessibility-reqs/ Please note that several people took follow up actions to provide additional details in the next week or so. Meanwhile, these are the concerns we identified: Concern: Users of Magnification We have concerns regarding the impact on users of magnification with respect to several WebVTT specifications. Has the group considered its specification's impact on users of magnification? Items raising this concern included: * Snap to flag * Sizing of the captions rendering area * Visibility of captions when text is zoomed Concern: The spec should include feature explanations in plain language We are concerned that too often in this document a feature's function can only be understood by parsing the provided algorithms. We would prefer plain language explanations be included. A specific case in point would be Sec. 6.1. Concern: Captions on the audio element We believe this section misrepresents the situation. It is incorrect to tell the user "There is nothing to render." When captions are provided for audio content there is indeed something to render, even if the available user agent is incapable of rendering it. Concern: CSS We did not identify specific items of concern, but are committed to follow up and may request a joint meeting to better understand the implementation of CSS in this specification.
