    Seeking a Parallel Element


      Hi all,


      I'm currently working on a multilingual AlR project with video playback that supports multiple audio tracks. Each flv video file is accompanied by a seperate mp3 audio track for each language that the app supports. I need to sync the playback of the video with the appropriate audio track for the selected language.


      I have been able to get this to work by using a ParallelElement and adding the video/audio.


      However when I try to seek the playback to a specific time i get a 'The specified capability is not currently supported' error.


      If i add a listener for Media Player Capability Change:


      mediaPlayer.addEventListener(MediaPlayerCapabilityChangeEvent.CAN_SEEK_CHANGE, doSeek);


      In the event hander, when I call seek on the media player, I do not get an error. However the video/audio does not seek.


      Does anyone have any advice on how I could get the seek behavior to work for a Parallel Element ? Do I need to manually add a trait the element? Or maybe to each media element individually?





      My code.....



      mediaContainer = new MediaContainer();
      mediaPlayer = new MediaPlayer();
      mediaPlayer.addEventListener(MediaPlayerCapabilityChangeEvent.CAN_SEEK_CHANGE, doSeek);
      var mediaFactory:DefaultMediaFactory = new DefaultMediaFactory();
      var videoElement:MediaElement = mediaFactory.createMediaElement(new URLResource('assets/video/part1.flv'));
      var audioElement:MediaElement = mediaFactory.createMediaElement(new URLResource('assets/video/part1_aud_eng.mp3'));


      var parallel:ParallelElement = new ParallelElement();
      mediaPlayer.media = parallel;
      // mediaPlayer.seek(10); // Throws error
