New Features in Flash Player 10.2

 == Stage Video hardware acceleration ==

 A new method for video playback in Flash Player  allows developers to leverage complete hardware acceleration of the video rendering pipeline, enabling best-in-class high definition (HD) playback performance.  Stage Video dramatically decreases processor usage enabling higher frame rates and reduced memory usage to deliver HD quality video on a broad range of devices. 

 == Support for full screen mode with multiple monitors ==

Full screen content will remain in full-screen on secondary monitors, allowing users to watch full-screen content while working on another display.

== Internet Explorer 9 hardware accelerated rendering support ==

Flash Player takes advantage of hardware accelerated graphics in Internet Explorer 9, utilizing hardware rendering surfaces to improve graphics performance and enable seamless composition.

 == Native custom mouse cursors ==

Developers can define custom native mouse cursors, enabling user experience enhancements and improved performance.

 == Sub-pixel text rendering ==

 Improved readability of text in Flash Player, especially for complex character-based languages.

  • Adobe is aware of issues with specific GPU driver versions and has notified manufacturers of any issues discovered during testing. Adobe recommends updating to the latest GPU driver versions to take advantage of the new Stage Video capabilities and other accelerated rendering features.

  • H.264 Video Hardware acceleration is not available on some Macintosh platforms. Please Refer the Apple Developer Connection technote on which Macintosh configurations support Hardware decoding: (

  • H.264 Hardware decoding on Linux is available as an experimental feature and has been tested on NVidia GT 330 and Broadcom BCM70015 GPUs. Users may choose to enable hardware decoding by adding EnableLinuxHWVideoDecode=1 in an mms.cfg configuration file. Users may experiance instability and crashes while watching hardware accelerated video. Please report any issues to

  • H.264 Video Hardware acceleration is not available for DRM-protected content on Broadcom graphics chips. 

  • For all supported Intel GPUs, we recommend using an Aero windows theme. Performance is significantly improved for fullscreen playback with Aero-enabled windows environments.

To work around this issue, users can disable hardware acceleration or download and install the beta version of Flash Player 10.3 which resolves this issue. To disable hardware acceleration, please visit To install the Flash Player 10.3 beta, please visit

  • Mac users may run into rendering issues with certain live streams due to an incompatibility between the stream encoding and the hardware decoder. We are aware of this issue and are working with Apple to resolve it. Users may workaround the issue by pausing and then unpausing the live stream. Developers can work around this issue by forcing the video to be decoded in software - create two Video objects, attach the stream to the first, then stop it and attach the stream to the second Video object (2819870, 2818959, 2779420).

  • Windows users with systems using NVidia Optimus technology which has two GPUs that switch dynamically depending on the graphics operation would occasionally see a black or green screen when trying to view video in fullscreen. We are working with NVidia to resolve the issue (2745863, 2821031).
