http://www.w3.org/Bugs/Public/show_bug.cgi?id=12544 Summary: MEDIA CONTROLLER requires track kind for in-band tracks Product: HTML WG Version: unspecified Platform: PC OS/Version: Windows XP Status: NEW Severity: normal Priority: P3 Component: HTML5 spec (editor: Ian Hickson) AssignedTo: ian@hixie.ch ReportedBy: jfoliot@stanford.edu QAContact: public-html-bugzilla@w3.org CC: mike@w3.org, public-html-wg-issue-tracking@w3.org, public-html@w3.org At this point, it is also not possible to discover the functionality that a in-band track provides through script. A similar problem was solved for the TextTrack object by introduction of a kind attribute. This is also necessary for the TrackList object, in particular to introduce a standard naming scheme across different media container formats for exposing the kind of data that their tracks provide. Therefore, we request addition of a getKind(in unsigned long index) function to the TrackList object, or something of equivalent functionality. The proposed list of values that kind should understand are: for video: * sign language video (in different sign languages as provided through getLanguage()) * captions (as in: burnt-in video that may just be overlays) * different camera angles * video mosaic for audio: * audio descriptions * language dub * commentary (such as director's commentary) * clear audio (see http://www.w3.org/WAI/PF/HTML/wiki/Media_Accessibility_Requirements#Clear_audio) -- Configure bugmail: http://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
