is as enjoyable an experience as possible. As a viewer, maximizing
enjoyment usually involves some tradeoffs: sure, you can watch a 1080p
high definition version of the newest movie trailer, but that might mean
choppy playback as your computer strains to keep up with the more
demanding processing required. We wanted to let you know about some
changes we’re making to help minimize those tradeoffs, so that you can
watch smoother, higher-quality video from your existing devices.
Adobe’s recently announced
Flash Player 10.2 beta release supports a new, more efficient video
display mechanism known as the Stage Video API. The full details of how
and why Stage Video speeds up video display can be found in Adobe’s technical documentation.
The Players Team will be gradually experimenting with Stage Video
playbacks on YouTube.com in the coming weeks, but as a developer using
the ActionScript 3 Player APIs, you can enable Stage Video playback for
your embedded video right away; simply add the wmode=direct parameter to the player URL that you’re using to reference the YouTube video. You’ll need the Flash Player 10.2 beta installed to take advantage of the accelerated playback, but playbacks will work for users with older Flash Player versions as well.
The Players Team knows that Stage Video for Flash playbacks is just one path to take toward improving video playback performance across the web.
