The initCallback for the Twitch player embed, which is described in the documentation here (player.md) doesn’t work anymore. It also seems to make the player not work at all.
I snooped Twitch’s source and found the new callback call.
Flash var:
eventsCallback=playerCallback
Example function:
function playerCallback(data) {
data.forEach(function(event) {
// event.event is the event's name
// event.data holds (from what I've seen) video data for the event
}
}
