FORMAT_TYPE dwFlags;
DWORD dwInputPin;
PIPELINE_TIME prerollTime;
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
-
