Constructor Detail

VideoViewLayer

public VideoViewLayer(java.lang.String id,
                      android.view.View v,
                      android.widget.RelativeLayout.LayoutParams rlp)

Create a video view layer as a set .

Parameters:

id - the unique identifier that describes the layer.

v - the view that is to be displayed

rlp - the layout parameters associated with the view.

VideoViewLayer

public VideoViewLayer(java.lang.String id,
                      android.view.View v,
                      android.widget.RelativeLayout.LayoutParams rlp,
                      boolean alwaysOn)

Construct a Video View Layer with a provided identifier and the view to be drawn over the top of the video being played.

Parameters:

id - the id of the video view

v - the view

rlp - the layout parameters for the view

alwaysOn - if the view needs to be explicitly defined in the layers intent string array extra (false) or if it is always going to be shown (true).

VideoViewLayer

public VideoViewLayer(java.lang.String id,
                      android.view.View v,
                      android.widget.RelativeLayout.LayoutParams rlp,
                      boolean alwaysOn,
                      boolean enableStockMetadata)

Construct a Video View Layer with a provided identifier and the view to be drawn over the top of the video being played.

Parameters:

id - the id of the video view

v - the view

rlp - the layout parameters for the view

alwaysOn - if the view needs to be explicitly defined in the layers intent string array extra (false) or if it is always going to be shown (true).

enableStockMetadata - if set to false, the stock metadata display for the frame center will not be rendered. It is up to this video view layer to render all desired metadata.

Method Detail

enableStructuredDecoding

public final void enableStructuredDecoding()

Enables more advanced structure decoding required by specifications such as VMTI. When a video is started, this is off by default.

start

public void start(ConnectionEntry connectionEntry,
                  boolean hasMetadata)

Called when video processing has started.

Parameters:

connectionEntry - the connection entry representing the video

stop

public void stop(ConnectionEntry connectionEntry)

Called when video processing has stopped.

Parameters:

connectionEntry - the connection entry representing the video

error

public void error(ConnectionEntry connectionEntry)

Called when video processing was unable to start due to an error.

Parameters:

connectionEntry - the connection entry representing the video

close

public final void close()

Call to close the drop down that is currently open. This can be used by implementations to close a drop down that is playing the video.

dispose

public void dispose()

Dispose the components that are set via the initialize

setPan

public void setPan(int x,
                   int y)

Called when the video is panned by the user.

Parameters:

x - the new center point x value

y - the new center point y value

setScale

public void setScale(double scale)

Called when the video is scaled by the user

Parameters:

scale - the new scale value

setViewMatrix

public void setViewMatrix(android.graphics.Matrix matrix)

Called when the video is panned or scaled by the user

Parameters:

matrix - Matrix used to transform a view so it matches the video Note: Any overlay view MUST match the size of the entire video surface. Drawing code should treat the video as if it's stretched to cover the entire surface, since this matrix includes aspect ratio scaling and centering.

videoSizeChanged

public void videoSizeChanged(int w,
                             int h)

Called when the video size has changed

Parameters:

w - New video width

h - New video height

metadataChanged

public void metadataChanged(KLVData rawData,
                            java.util.Map<DecodedMetadataItem.MetadataItemIDs,DecodedMetadataItem> items)

The metadata change listener. This supplies both decoded and raw data

Parameters:

rawData - The raw metadata wrapped in a KLVData object.

items - the decoded values as ids and items.

isAlwaysOn

public boolean isAlwaysOn()

Return true if the layer is always on . In the case that the layer is not always on, it will need to be explicity requested in order to be shown. See the intent used to launch the video with the extra intent.getStringArrayExtra("layers");

Returns:

true if the layer is always on or false if the layer needs to be explitly mentioned in the layers string array.

getEntry

public ConnectionEntry getEntry()

Get a copy of the connection entry

Returns:

onLongPress

public void onLongPress(android.view.MotionEvent e)
