Detailed Description

Simple base class for acquiring video data.

Definition at line 27 of file mitkVideoSource.h.

Constructor & Destructor Documentation

VideoSource()

mitk::VideoSource::VideoSource ( )

protected

init member

~VideoSource()

mitk::VideoSource::~VideoSource ( )

overrideprotected

deletes m_CurrentVideoTexture (if not 0)

Member Function Documentation

FetchFrame()

virtual void mitk::VideoSource::FetchFrame ( )

virtual

assigns the grabbing devices for acquiring the next frame. in this base implementation it does nothing except incrementing m_FrameCount

GetCapturePaused()

virtual bool mitk::VideoSource::GetCapturePaused ( ) const

virtual

Returns

true, if capturing is currently paused, false otherwise

GetFrameCount()

virtual unsigned long mitk::VideoSource::GetFrameCount ( ) const

virtual

Returns

the current frame count

GetImageHeight()

virtual int mitk::VideoSource::GetImageHeight ( )

virtual

Returns

the current frame height (might be 0 if unknown)

GetImageWidth()

virtual int mitk::VideoSource::GetImageWidth ( )

virtual

Returns

the current frame width (might be 0 if unknown)

GetVideoTexture()

virtual unsigned char* mitk::VideoSource::GetVideoTexture ( )

pure virtual

Returns

a pointer to the image data array for opengl rendering.

IsCapturingEnabled()

virtual bool mitk::VideoSource::IsCapturingEnabled ( ) const

virtual

Returns

true if video capturing is active.

Smart pointer defs

PauseCapturing()

virtual void mitk::VideoSource::PauseCapturing ( )

virtual

toggles m_CapturePaused In Subclasses this function can be overwritten to take measurs to provide a pause image, BUT DO NOT FORGET TO TOGGLE m_CapturePaused

StartCapturing()

virtual void mitk::VideoSource::StartCapturing ( )

virtual

advices this class to start the video capturing. in this base implementation: toggles m_CapturingInProcess, resets m_FrameCount ATTENTION: this should be also done in subclasses overwriting this method

StopCapturing()

virtual void mitk::VideoSource::StopCapturing ( )

virtual

advices this class to stop the video capturing. in this base implementation: toggles m_CapturingInProcess, resets m_FrameCount ATTENTION: this should be also done in subclasses overwriting this method

Member Data Documentation

m_CaptureHeight

int mitk::VideoSource::m_CaptureHeight

protected

should be filled when the first frame is available default: 0

Definition at line 112 of file mitkVideoSource.h.

m_CapturePaused

bool mitk::VideoSource::m_CapturePaused

protected

Saves if the capturing is currently paused, i.e. this will not fetch any further frames but provide the current frame as long as m_CapturePaused is true default: false

Definition at line 133 of file mitkVideoSource.h.

m_CaptureWidth

int mitk::VideoSource::m_CaptureWidth

protected

should be filled when the first frame is available default: 0

Definition at line 106 of file mitkVideoSource.h.

m_CapturingInProcess

bool mitk::VideoSource::m_CapturingInProcess

protected

saves if capturing is in procress default: false

Definition at line 118 of file mitkVideoSource.h.

m_CurrentVideoTexture

unsigned char* mitk::VideoSource::m_CurrentVideoTexture

protected

finally this is what the video source must create: a video texture pointer default: 0

Definition at line 100 of file mitkVideoSource.h.

m_FrameCount

unsigned long mitk::VideoSource::m_FrameCount

protected

Saves the current frame count. Incremented in FetchFrame(). Reset to 0 when StartCapturing() or StopCapturing() is called. default: 0
