Hi Andrew, How are you? hope doing well. I have one more question about the audio-description… Is it possible to automatically “stop” & “re-start” the video while the audio-description is playing? If yes, could you help me for the corresponding code to use? Moreover, can that interfere with the synchronized captions? Thanks for your help, Jackir _____ De : Andrew Kirkpatrick [mailto:akirkpat@adobe.com] Envoyé : mercredi 31 octobre 2007 03:21 À : jassanaly@ipedis.com Cc : w3c-wai-ig@w3.org Objet : RE: Flash player & audio-description Sure, it is pretty simple. Add this code to your FLA file (it assumes the instance name for your video playback component is my_FLVPlybk): import fl.video.*; my_FLVPlybk.addASCuePoint(8.35, "ASpt1"); //add AS cue point my_FLVPlybk.addASCuePoint(23.23, "ASpt2"); //add 2nd Aspt my_FLVPlybk.addEventListener(MetadataEvent.CUE_POINT, cp_listener); function cp_listener(eventObject:MetadataEvent):void { if (eventObject.info.name == "ASpt1") { var snd0:Sound = new Sound(new URLRequest("sphere.mp3")); snd0.play(); } else if (eventObject.info.name == "ASpt2") { var snd:Sound = new Sound(new URLRequest("transfrm.mp3")); snd.play(); } } This will play two audio descriptions, one at 8.35 seconds and another at 23.23 seconds. You would, of course, modify the times to match when your audio descriptions need to be played and modify the AD file names. You'd likely have more files for description too, but this example should get you started. You would also want to provide some UI to enable the AD user to turn the descriptions on and off. You could make the descriptions on by default when a screen reader is detected as an added feature... Hope this helps.

Other question: is it possible to add synchronised audio-description to videos (in .FLV format)? For Real Player or QuickTime videos, we have examples on: <http://www.pbs.org/wgbh/evolution/educators/teachstuds/tvideos.html> http://www.pbs.org/wgbh/evolution/educators/teachstuds/tvideos.html But for Flash videos, I do not have any examples. Thanks for your help Jackir
