I brought this up with Robin, and we tried it in a couple of browsers using the debugger. It appears to be supported by at least two. I wrote a demo that I use in my documentation, and I've posted it on the sample server. It appears to work fine in IE11 and Chrome. Firefox seems not to like the TextTrack info, but I didn't debug it. Here's the url: http://samples.msdn.microsoft.com/Workshop/samples/media/addtexttracktest.html Sample's pretty simple: <!DOCTYPE html > <html > <head> <title>Add Text Tracks example</title> </head> <body> <video id="video1" controls="controls" muted="muted"> <!-- change to your own mp4 video file --> <source src="http://ie.microsoft.com/testdrive/Videos/BehindIE9ModernWebStandards/Video.mp4" /> HTML5 Video not supported </video> <script> var video = document.getElementById("video1"); var startTime, endTime, message; var newTextTrack = video.addTextTrack("captions", "sample"); newTextTrack.mode = newTextTrack.SHOWING; // set track to display // create some cues and add them to the new track for(var i=0;i<30;i++){ startTime = i * 5 ; endTime = ( (i * 5) + 5); message = "This is number " + i; newTextTrack.addCue(new TextTrackCue(startTime, endTime, message)); } video.play(); </script> </body> </html> -----Original Message----- From: Silvia Pfeiffer [mailto:silviapfeiffer1@gmail.com] Sent: Saturday, April 12, 2014 9:37 PM To: Sam Ruby Cc: public-html Subject: Re: HTML5 CR "at risk" features On Sat, Apr 12, 2014 at 8:31 PM, Sam Ruby <rubys@intertwingly.net> wrote: > On 04/11/2014 09:41 PM, Silvia Pfeiffer wrote: >> >>> HTMLMediaElement.addTextTrack - Discussed at F2F meeting >> >> >> I tried to find out from the minutes why addTextTrack is at risk, but >> it was only mentioned without reasons. > > > From http://www.w3.org/2014/04/09-html-wg-minutes.html : > > ... lots of failures on HTMLMediaElement.addTextTrack ... mostly > failing at the moment That's what I saw. I dug around a bit and assume it's based on this test: http://w3c.github.io/html/test-results/less-than-2.html#test-file-62 At first sight, I think the test might expect the wrong kinds of errors. Will investigate. Cheers, Silvia.
