Method Detail

getHandler

public static PrismMediaFrameHandler getHandler(java.lang.Object provider)

getTexture

public Texture getTexture(Graphics g,
                          VideoDataBuffer currentFrame)

This should only ever be called during a render cycle. Any other time it will return null. Note that a returned texture should be unlocked when the caller no longer needs it.

Parameters:

g - the Graphics context about to be rendered into

Returns:

the current media texture valid for rendering into g or null if called outside a render cycle

updateTexture

private void updateTexture(Graphics g,
                           VideoDataBuffer vdb,
                           PrismMediaFrameHandler.TextureMapEntry tme)

releaseData

private void releaseData()

releaseTextures

public void releaseTextures()

Call this when you no longer need to render movie frames, for example when playback stops.

factoryReset

public void factoryReset()

Description copied from interface: ResourceFactoryListener

Called when the factory is lost and about to be reset. This may result in some of the vram based resources becoming invalid. The listeners can chose which resources to let go of depending on whether they're based in vram.

Specified by:

factoryReset in interface ResourceFactoryListener

factoryReleased

public void factoryReleased()

Description copied from interface: ResourceFactoryListener

Called when the factory is released. This may result in all resources becoming invalid. The listeners should let go of all resources created from this factory.

Specified by:

factoryReleased in interface ResourceFactoryListener
