WebVTT Implementation Status

The discussion was build on top of the following aspects:

webkit/blink/presto - started implementing at the same time (one and half year ago) - basic support for the spec is everywhere - ships in various versions

firefox - doesn't ship in the default

ie - ?

Some other preliminary notes (before the discussion on the document):

  • rendering is generally lagging in behind and maybe not interoperable
  • vttregions aren't shipped anywhere in the end so far
  • how to test the very latest features?
  • how to find out the lowest common denominator (the common features implemented) ?
  • do we want to think about version numbers for the spec? that's what the recommendation track means: fixed feature set
  • for the webvtt files? versioning on the web hasn't been a great success
  • browsers don't care about version number
