DeinterlaceBuffer()

template<typename T >

CVD::DeinterlaceBuffer< T >::DeinterlaceBuffer	(	CVD::VideoBuffer< T > &	buf,
		Fields::Fields	fields = Fields::OddEven,
		bool	line_double = false
	)

Construct a DeinterlaceBuffer by wrapping it around another VideoBuffer.

Parameters

buf	The buffer that will provide the raw frames
fields	The fields to

Member Function Documentation

frame_pending()

template<typename T >

virtual bool CVD::DeinterlaceBuffer< T >::frame_pending ( )

inlinevirtual

Is there a frame waiting in the buffer? This function does not block.

See is_live and is_flushable.

Implements CVD::RawVideoBuffer.

frame_rate()

template<typename T >

virtual double CVD::DeinterlaceBuffer< T >::frame_rate ( )

inlinevirtual

What is the (expected) frame rate of this video buffer, in frames per second? If OddEven or EvenOdd are selected, this will be reported as twice the original buffer's rate.

Implements CVD::RawVideoBuffer.

put_frame()

template<typename T >

void CVD::DeinterlaceBuffer< T >::put_frame ( CVD::VideoFrame< T > *  f )

virtual

Tell the buffer that you are finished with this frame.

Typically the VideoBuffer then destroys the frame.

Parameters

f	The frame that you are finished with.

Implements CVD::VideoBuffer< T >.

seek_to()

template<typename T >

virtual void CVD::DeinterlaceBuffer< T >::seek_to ( double  )

inlinevirtual

Go to a particular point in the video buffer (only implemented in buffers of recorded video)

Parameters

t	The frame time in seconds

Reimplemented from CVD::RawVideoBuffer.

size()

template<typename T >

ImageRef CVD::DeinterlaceBuffer< T >::size ( )

virtual

The size of the VideoFrames returns by this buffer.

This will be half the height of the original frames.

Implements CVD::RawVideoBuffer.

source_buffer()

template<typename T >

virtual RawVideoBuffer* CVD::DeinterlaceBuffer< T >::source_buffer ( )

inlinevirtual

Which video grabber provides the source images for this video grabber.

Reimplemented from CVD::RawVideoBuffer.
