The pop-out works with these services if you click the button manually, so it's definitely an issue with the new feature. In my tests, the video pop-out only worked with YouTube, I tried it with Amazon Prime, Steam, Twitter, Dailymotion, but none of these videos triggered the option automatically. That's a little annoying, but not a dealbreaker. So you will have to either manually trigger the pop-out, or close the tab and open the same video in a new tab. In this particular scenario, the pop-out does not appear even when you reload the tab. The new feature isn't perfect, as the video pop-out seems to stop working if you close the panel or go back to the source page to pause/resume the media, and switch to a different tab. There are no controls to set the transparency level manually. Additionally, the page allows you to enable a transparent version of the pop-out player, which can be handy if you like to read the text on a page behind the panel. Users who don't like the automatic video pop-out option can toggle it from the Opera browser settings. Jump to a different tab and it pops-out again. the original YouTube page, will automatically toggle the normal video mode. Switching to the tab which contains the media, e.g.

It is a floating window that you can resize, or move around the screen per your requirements. The PiP window has some playback controls to pause/play, control the volume, close the panel. Let's say you're watching a video on YouTube, but switch to a different tab, the video will be displayed on top of the new tab in a mini-panel.
