    Hello srikanth,

    There are many approaches you can take for this scenario. One of them is to add an invisible(Opacity=0) MediaElement and play the audio description with it. For example, before playing the actual media item with RadMediaPlayer, you can play the audio description. When the audio description finishes, you can then play the media item from RadMediaPlayer.
    I am attaching a sample project that might get you in the right direction. Have a look at it and let me know how it works for you.

    Hi Srikanth,

    Sorry for the misunderstanding. Probably I did not get what you mean by "so when media file is playing the audio description should be added". Could you please walk me through a sample scenario you want to achieve?
    I have few questions. When the user plays the media file, where do you want to add the audio description? Do you want the audio description to play while the media file is playing as well?  Or do you want the user, before playing the media file to hear the audio description and as soon as the audio description finishes, then to start the media file again.
    It would be great if you can give me more information on your scenario so I can assist you better.

    Hi thanks for ur reply. I am implementing a web application for visually challenged where I use a video to be displayed on one of my pages. I would like to make the video completely accessible to the user. So, I would like to add audio descriptions for the video. Generally audio descriptions are separate audio files attached to the video. But in my case, in order to reduce the bandwidth, I am gonna make use of the screen reader to read the text descriptions to the user.

    Thus I need to include the text description for the video in the media player and this text description should be read by the screen reader as the media plays. The purpose is, to help the user understand what is going on when there is no audio in the video.

    Thanks.

    Hi Srikanth,

    Now I understand. The scenario you describe is currently not supported. I did a little research using Windows' Narrator and RadMediaPlayer, with the presumption that the narrator will read the text set by the AutomationPeer. Even though I did set such text and focused the respective media item, the narrator did not read the help text. This calls for further research. We would definitely support this scenario in RadMediaPlayer's future versions, but currently I cannot bind to a specific date. Let me know what's your opinion on the matter.

    All the best,
