I am planning to build a system to broadcast public events (trials, meetings, conferences).
A key request will be the insertion of live subtitles to the A/V stream.
The subtitles will be "live" since they will be produced by an operator while the event will happen.
I suppose the HTML5 "track" element is not yet implemented by any of the major browsers, but: can I expect to eventually use it for live subtitles? Will I be able to inject the subtitle to the page while the stream is playing?
Please Look at the following links. Looking at the link i am having to believe it should be possible as they are using Js to show subtitles

You may also consider http://mozillapopcorn.org/ which is to show content on timing of the video. So technically u can use this with ajax to show/stream subtitles
