Re: Evidence of 'Wide Review' needed for VTT

With JW Player, we implemented basic parsing of cues and rendering of
cues according to the draft spec. Especially in the area of rendering,
the spec is well defined and very helpful to implementors. With TTML
and SRT, we had to be much more creative in doing the rendering. Let
me know what exactly you'd like to see in terms of feedback on the
spec; our player engineers can put that together.

We have not yet implemented regions. It's a bit hard to comment on the
spec without doing the work; you always find the small details when
implementing. It reads very defined and focused to the use case though
(608 compatibility). If you require comments from people that have
implemented the spec, we could look into prioritizing this work for JW
Player.

The one item I'm missing from the spec is inline CSS, but that's
pushed to V2 right?
(https://www.w3.org/Bugs/Public/show_bug.cgi?id=15023) On platforms
like Flash or native Android, we'd like to have all cue styling inline
since there's no CSS. Publisher also need it when converting from
legacy formats (608, TTML) into VTT. In these formats, the styling
also "lives" inline.
