What should the track selection algorithm be? Do you still want to keep the enabled *property* so that scripts can switch between different tracks of a group, just like the browser context menu? I am not very optimistic about UA track selection being very useful being applying the 'media' attribute. I also have a feeling we haven't completely thought through what kind of selection belong on the <trackgroup><track> level and what belongs in <track><source> (assuming we'll go with that, just like for <audio> and <video>). -- Philip Jägenstedt Core Developer Opera SoftwareReceived on Friday, 5 March 2010 03:39:30 UTC
