If you are curious about the “popup” player from the new Samsung Galaxy SIII, you can get a similar app from the Play Store called Super Video that does the same and more. Super Video allows you to pop out a video in a floating window just like with the Galaxy S3.
Unlike with the Galaxy S3′s popup player, Super Video allows you to resize the floating window to make it bigger/smaller to fit your needs. Not only do you get a resizable window, but Super Video also supports YouTube videos. By clicking the share button in the default YouTube app, if you select Super Video, it will open in the floating window. Pretty cool in my opinion.
