Media Overlay is disabled

Hello, support for talking / read aloud EPUB3 books (aka Media Overlays) is
not implemented yet in Readium-Javascript. The developement team is working
on it.

I'm now trying to support SMIL book, unfortunately the Media Overlay is
disabled on javascript Readium. In Readium.js core I found the disabled
line:
var moObject = new EpubParser.MediaOverlay()
but I couldn't find the EpubParser.MediaOverlay anywhere, even from the
Github history.
I would like to know if there is any plan to re-implement MO in Readium?
Thank you.

Hello, we are evaluating Readium.js in order to include this library in a web application and very interested in MediaOverlay feature too.. Is there any update on this? Thank you,
Fabrizio

The Media Overlays "engine" (which has sophisticated features like skippability, escapability, linear time-based navigation, phrase-level navigation, playback rate, TTS, configurable highlighting, shared-SMIL support, etc.) is essentially written in Javascript, and is already used in native ReadiumSDK apps (OSX, iOS, Android, WinRT). However, the pure-Javascript ReadiumJS app currently lacks some SMIL parsing logic (XML to JSON data model), so the app cannot use the publication's Media Overlays. I think that the JS dev team is currently working on higher-priority tasks, but MO is still high on the todo list. Daniel

• update -
  Support for EPUB3 Media Overlays has been available since the first official release of the Readium Chrome extension, which has been updated a couple of days ago with even better support for advanced MO features. Closing the issue.
