On devices that support GPU (hardware) acceleration, you can use a flash.media.StageVideo object to process video directly on the device hardware.
A combination of different factors determine when and how you can use
StageVideo. The following table presents a snapshot of some of the requirements and restrictions that are associated with using StageVideo. These requirements and restrictions are subject to change.
|Platform||Windows and Mac OS|
|Browsers and wmode settings||
On Flash 15, set wmode=opaque so you can use HTML overlays.
The following browsers currently do not support hardware acceleration:
On Flash 14 and earlier, if the browser does not support hardware acceleration, the Flash player can render directly to the GPU, but set wmode=direct to enable this rendering.
Tip: GPU drivers that are older than 2009 might need to be updated as these drivers might lack support for hardware acceleration.
|NetStream object||The StageVideoEvent.RENDER_STATE event is not dispatched unless you attach a NetStream object to the StageVideo object.|
