^ polyfill for JS. This would mean we could Direct Stream more often, and avoid the weird subtitle artifacts the transcoder sometimes gives. Also, easy switching on/off subs without restarting a transcode. No SSA support yet, but it's high on the TODO list.
There's a slight catch though. No currently shipping browser supports either of these features/standards.
Nevermind, at first I didn't understand that this in fact provides the support in javascript, while browsers don't implement it natively.
Very interesting then, it should definitely be considered.
