While you are waiting for a word from Google, I created a plugin to fix it. Download it here:
https://www.dev.powered-by-haiku.co.uk/solutions/getvideodata/code/getvideodata.js
(NOTE: You need to copy and paste the URL into the browser to get the code because hotlinking is not allowed)
Apply it just like any other JW plugin:
"plugins":{ "getvideodata.js":{} }
EDIT: Now this update has been updated to serve the autorun script: true. Please note that the latest versions of Chrome now block multimedia playback that does not start using user gestures, and since the JW Player does not process the received error state gracefully (when trying to autostart YouTube, for example), the player will get into a visible endless buffering state. This plugin resolves this by canceling the autorun request in Chrome and leaving it to the user to start playback.
