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 |
---|---|
Flash player |
|
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. |
