Hi Silvia,

That's very interesting news...
Anything that brings a more consistent approach to implementation of subtitling support across browsers is great!

Thanks for sharing :-)

Hi David,

I don't know where the view that the spec will never reach interoperability comes from. Not all activities are taking place in the TTWG for WebVTT.

We just had our annual FOMS meeting and we have Gary on board as a new editor of the WebVTT spec. Gary gave a status update on the implementation of the WebVTT features and their interoperability based on the Web Platform Tests (WPT).

We discussed with browsers that an interoperable implementation is required. Implementers from Mozilla, Apple and Google were present and agreed to move forward with implementations. There were some committments made and there were many bugs registered.

I can't speak for Gary, but I believe it's Gary's goal to take the interoperability report forward.
Many test are already green: http://slides.com/gkatsev/wpt-webvtt#/2/4 .

At FOMS, video player vendors reconfirmed that they would like to see the WebVTT CR implemented by all browsers. They are already using the Apple implementation which is regarded as the "gold standard" of WebVTT implementation. The second best implementation is in VLC, though it's not included in the WPT list.

Is there any way that the W3C can send out an implementation call-to-action to browser vendors to support this effort? It's a matter of prioritisation of accessibility implementation by browsers that is now holding back progress. We're particularly concerned about those browser that were not present at FOMS.

Kind Regards,
