Member Function Documentation

Close()

void Close ( )

abstract

Closes the Block.

When closed it can neither accept, nor deliver data.

EndOfStream()

bool EndOfStream ( int inputIndex )

abstract

Tells the Block that there's no more data for the specified input socket.

Parameters

inputIndex

Specifies the index of the input socket for which there's no more data.

Returns

true if the operation is sucessfull; otherwise false.

Flush()

bool Flush ( )

abstract

Flushes the data buffered in the Block to the output.

Returns

true if the buffered data is sucessfully flushed; otherwise false.

Open()

bool Open ( )

abstract

Initializes the Block based on the specified input and desired output.

Returns

true if the Block is sucessfully initialized and is ready to process data; otherwise false.

Pull()

bool Pull ( out int outputIndex, MediaSample outputSample )

abstract

Pulls output data from the Block.

Parameters

outputIndex	Returns the index of the output socket to which the data belongs.
outputSample	The MediaSample object receives the output data in the MediaBuffer property.

Returns

true if the Block has successfully generated output, otherwise false.

PullUnmanaged()

bool PullUnmanaged ( out int outputIndex, MediaSample outputSample )

abstract

Pulls output data from the Block.

Parameters

outputIndex	Returns the index of the output socket to which the data belongs.
outputSample	The MediaSample object receives the output data in the UnmanagedMediaBuffer property.

Returns

true if the Block has successfully generated output, otherwise false.

Push()

bool Push ( int inputIndex, MediaSample inputSample )

abstract

Pushes input data to the Blocks.

Parameters

inputIndex	Specifies the index of the input socket whose data is pushed to the Block.
inputSample	A MediaSample object that contains the input data in the MediaBuffer property.

Returns

true when the Block has successfully processed the input data, otherwise false.

PushUnmanaged()

bool PushUnmanaged ( int inputIndex, MediaSample inputSample )

abstract

Pushes input data to the Block.

Parameters

inputIndex	Specifies the index of the input socket whose data is pushed to the Block.
inputSample	A MediaSample object that contains the input data in the UnmanagedMediaBuffer property.

Returns

true when the Block has successfully processed the input data, otherwise false.
