BufferFormat

  • Article

The BufferFormat structure describes the format of a buffer.

Syntax

typedef struct stcBufferFormat
{
  FORMAT_TYPE  dwFlags;
  DWORD  dwInputPin;
  PIPELINE_TIME  prerollTime;
  struct VideoFormatInfo
  {
    double  dblWidthRatio;
    double  dblHeightRatio;
  }  
}  BufferFormat;

Members

dwFlags

One or more values from the FORMAT_TYPE enumeration, combined with a bitwise OR, that describe the format of the data in the buffer and how it should be treated.

dwInputPin

A DWORD that specifies the one-based input stream on the node.

prerollTime

A PIPELINE_TIME structure that specifies the preroll time. This value gives the transform extra time to initialize. Microsoft advises against specifying this value.

dblWidthRatio

A double that specifies the width ratio of video objects.

dblHeightRatio

A double that specifies the height ratio of video objects.
