Detailed Description

VideoStreamInfo describes an elementary video stream.

Constructor & Destructor Documentation

~VideoStreamInfo ( )
protected

This object can be destroyed only by its implementation.

The caller must use Reference::release.

Member Function Documentation

virtual VideoStreamInfo* clone ( ) const
pure virtual

Creates a copy of this object.

Returns
A new VideoStreamInfo. The caller is responsible for releasing the new object when it is not needed anymore.
See Also
Object Management

Implements StreamInfo.

virtual ColorFormat::Enum colorFormat ( ) const
pure virtual

Returns the video color format.

Returns
A ColorFormat::Enum constant.
virtual bool_t copyTo ( VideoStreamInfo destination) const
pure virtual

Copies the state of the current object to a destination object of the same type.

The reference count of the source and the destination is not modified.

Parameters
destination[out] A pointer to the destination object
Returns
TRUE The object state is copied, FALSE otherwise.
virtual int32_t displayRatioHeight ( ) const
pure virtual

Returns the vertical dimension of the display aspect ratio.

Returns
vertical display ratio.
virtual int32_t displayRatioWidth ( ) const
pure virtual

Returns the horizontal dimension of the display aspect ratio.

Returns
horizontal display ratio.
virtual bool_t frameBottomUp ( ) const
pure virtual

Returns whether internally the video frame is stored upside down.

Returns
TRUE The frame is stored upside down (vertically flipped) but logically it should be displayed normally. This is typical for bitmaps. FALSE The frame is displayed as it is stored - top row is first in memory, bottom row is last.
virtual int32_t frameHeight ( ) const
pure virtual

Returns the video frame height.

Returns
video frame height in pixels.
virtual double frameRate ( ) const
pure virtual

Returns the video frame rate.

Returns
video frame rate in frames per second.
virtual int32_t frameWidth ( ) const
pure virtual

Returns the video frame width.

Returns
video frame width in pixels.
virtual ScanType::Enum scanType ( ) const
pure virtual

Returns the scan type of the video frame.

Returns
Scan type
virtual void setColorFormat ( ColorFormat::Enum  colorFormat)
pure virtual

Sets the video color format.

Parameters
colorFormatcolor format
virtual void setDisplayRatioHeight ( int32_t  displayHeight)
pure virtual

Sets the vertical dimension of the display aspect ratio.

Parameters
displayHeightThe value has no meaning on its own. It serves only to express the display aspect ratio.
Returns
vertical display ratio.
virtual void setDisplayRatioWidth ( int32_t  displayWidth)
pure virtual

Sets the horizontal dimension of the display aspect ratio.

Parameters
displayWidthThe value has no meaning on its own. It serves only to express the display aspect ratio.
Returns
horizontal display ratio.
virtual void setFrameBottomUp ( bool_t  bottomUp)
pure virtual

Sets whether internally the video frame is stored upside down.

Parameters
bottomUpTRUE the frame is stored upside down, FALSE the frame is stored normally
virtual void setFrameHeight ( int32_t  frameHeight)
pure virtual

Sets the video frame height.

Parameters
frameHeightin pixels
virtual void setFrameRate ( double  frameRate)
pure virtual

Sets the video frame rate.

Parameters
frameRatein frames per second.
virtual void setFrameWidth ( int32_t  frameWidth)
pure virtual

Sets the video frame width.

Parameters
frameWidthin pixels.
virtual void setScanType ( ScanType::Enum  scanType)
pure virtual

Sets the scan type of the video frame.

Parameters
scanType
Returns
TRUE The scan type is set, FALSE otherwise.
virtual void setStride ( int32_t  stride)
pure virtual

Sets the video image stride.

Parameters
strideImage stride in bytes.

Stride is the distance in bytes from the start of one row of pixels in memory to the start of the next row of pixels. It is also called a pitch.

virtual int32_t stride ( ) const
pure virtual

Returns the video image stride.

Returns
Image stride in bytes.

Stride is the distance in bytes from the start of one row of pixels in memory to the start of the next row of pixels. It is also called a pitch.
