Version 12.17

System Windows 7

of Opera.

Thank you for posting the suggestion as it worked in my case.

I can play the vp9 version in Chrome just fine but Opera plays in the the video in flash player.
YouTube wasn't/isn't serving HTML5 video formats properly to Opera (one issue involving the codec and another involving the resolutions available). Then Opera added a browser.js patch to force YouTube pages to deliver the Flash version of the player as a workaround while YouTube team would fix their site. That's why you're receiving the Flash version. If you disable Flash in opera:plugins you might be able to play the video in the HTML5 version.
