    Hi,
    This is possible in JW Player 6.11 using ID3 Tags discussed here.
    You can insert such metadata initially into an rtmp stream using this guide.
    and then convert those into ID3 tags for use with iOS/HLS

    Hi,

    Daren has already sent you an article that provides some sample code for a module you can use. It's the "How to inject cue points or metadata" forum article.
    You also have an example there for a Flash Client/Live stream player with controls to inject the caption.

    Hello Kishor,

    To be able to better assist you with this Java API code implementation it would be best to have you log a ticket and include your code, and the following directories in a zip file: conf/ logs/ along with a link to this thread as a reference and log a support ticket through your account portal. After logging into your account here: https://www.wowza.com/portal/account you then click on the My Support tab and then click on the link to open a support ticket for Wowza Streaming Engine.

    Regards,
    Jason Hatchett
