RE: Implementation Status [via Web Media Text Tracks Community Group]

Wrt the required header - I'll get that fixed up in our engine ASAP.

I'd love to see the test suite, if there is one...

Thanks
Frank

Nice. I'm a bit surprised IE implements the old "WEBVTT FILE" header.

Could you also test Opera 12 (Presto)? From memory, I think its support is something like:

Required Header WEBVTT
File MIME Type sniffing
Menu in video controls to select tracks 
JavaScript TextTrack API ✔
Rendering of text-only captions & subtitles ✔
Cue styling with ::cue and ::cue() ✔
Cue markup incl. Timestamps ✔ (<ruby> is rendered inline)
Vertical Cue setting 
Line, Align, Position, Size Cue settings ✔
Comments (NOTE) ✔
Regions 
Rendering of text descriptions 
Rendering of chapters 

It's not clear to me what it means for an implementation to support "Comments (NOTE)" since it falls out of the parsing requirements to discard them even before NOTE was in the spec.

How do you determine if a feature is "✔" or "✔ (buggy)" or ""? Are you running a testsuite?
