Method Detail

getInputSurface

public android.view.Surface getInputSurface()

Retrieving this Surface can be done from any thread, but API calls on the Surface may not be thread safe.

Returns:

The input surface to be attached to some image producer such as a camera or opengl context

setSize

public void setSize(int width,
                    int height)

Set the size of the surface

Parameters:

width - width in pixels

height - height in pixels

getDescriptor

public Device.Descriptor getDescriptor()

Specified by:

getDescriptor in class Device

getPreviewView

public ImagePreviewView getPreviewView()

Description copied from class: ImageDevice

Gets a ImagePreviewView that will display a preview of this device's contents. Warning: Using many ImagePreviewViews at once may result in performance degradation.

Specified by:

getPreviewView in class ImageDevice

getPreviewView

public ImagePreviewView getPreviewView(BroadcastConfiguration.AspectMode aspectMode)

Specified by:

getPreviewView in class ImageDevice

isValid

public boolean isValid()

Specified by:

isValid in class Device

getTag

public java.lang.String getTag()

Specified by:

getTag in class Device

setRotation

public void setRotation(float rotation)

Description copied from class: ImageDevice

Sets the rotation of the ImageDevice.

Specified by:

setRotation in class ImageDevice

Parameters:

rotation - Rotation in radians

rotateOnConfigurationChanges

public void rotateOnConfigurationChanges(boolean enable)

Description copied from class: ImageDevice

Enables/disables rotations of this ImageDevice when the physical device is rotated. When this is enabled, the image source will be rotated to match configuration changes. This is often useful with camera devices, for example. When this is disabled, the image source will not be rotated to match configuration changes. This is often useful for custom image sources or if the camera ought to be locked to a particular orientation to match the application.

Specified by:

rotateOnConfigurationChanges in class ImageDevice

Parameters:

enable - Whether this device should rotate on configuration changes (e.g. when the physical device is rotated).

willRotateOnConfigurationChanges

public boolean willRotateOnConfigurationChanges()

Specified by:

willRotateOnConfigurationChanges in class ImageDevice

Returns:

Whether this ImageDevice will rotate on configuration changes.

getHandle

protected long getHandle()
