Constructor Detail
VideoDigitizer
public VideoDigitizer()
throws QTException
Opens the specified video component,'vidg', with any subType.
SGPanels should not be accessable by the public.
QuickTime::OpenADefaultComponent
VideoDigitizer
public VideoDigitizer(int subType)
throws QTException
Opens the specified video component,'vidg', with the given subType.
SGPanels should not be accessable by the public.
QuickTime::OpenADefaultComponent
Parameters:subType - The video component sub type
Method Detail
getNumberOfInputs
public int getNumberOfInputs()
throws StdQTException
Returns the number of input sources that a video digitizer component supports.
QuickTime::VDGetNumberOfInputs
Returns:the number of inputs
setInput
public void setInput(int input)
throws StdQTException
Allows applications to select an input video source for a video digitizer component.
This is a 0 based index.
QuickTime::VDSetInput
Parameters:input - the input video source.
getInput
public int getInput()
throws StdQTException
Returns the index that identifies the currently active input video source.
QuickTime::VDGetInput
Returns:the index for the current input device
setClipRgn
public void setClipRgn(Region clipRegion)
throws StdQTException
Allows you to define a clipping region.
QuickTime::VDSetClipRgn
Parameters:clipRegion - specifies the clip region
clearClipRgn
public void clearClipRgn(Region clipRegion)
throws StdQTException
Allows you to disable all or part of a clipping region that was previously set.
QuickTime::VDClearClipRgn
Parameters:clipRegion - specifies the clipping region to clear. This must correspond to all
or part of a previously set clip region.
setClipState
public void setClipState(boolean clipEnable)
throws StdQTException
Allows your application to control whether clipping is enabled or disabled.
QuickTime::VDSetClipState
Parameters:clipEnable - if true clipping is enabled, otherwise it is disabled.
getClipState
public boolean getClipState()
throws StdQTException
Allows your application to determine if clipping is enabled or not.
QuickTime::VDGetClipState
Returns:if true clipping is enabled otherwise it isn't.
getDigitizerInfo
public DigitizerInfo getDigitizerInfo()
throws StdQTException
Allows your application to determine the
capability and status information about a specified video digitizer component.
QuickTime::VDGetDigitizerInfo
Returns:if true clipping is enabled otherwise it isn't.
getInputFormat
public int getInputFormat(int input)
throws StdQTException
Determines the format of the video signal provided by a specified video input source.
Parameters:input - The input video source for this request. Video digitizer components number video sources sequentially, starting at 0. So, to request
information about the first video source, an application sets this parameter to 0. Applications can get the number of video sources supported by a
video digitizer component by calling getNumberOfInputs ().Returns:the video format of the specified input source.
setInputStandard
public void setInputStandard(int input)
throws StdQTException
Specifies the input signaling standard to digitize.
Parameters:input - the input signaling standard. (ntscIn, palIn, secamIn)
