BDA_TRANSPORT_INFO structure (bdamedia.h)

  • Article

The BDA_TRANSPORT_INFO structure describes formatting for a stream connection.

Syntax

typedef struct tagBDA_TRANSPORT_INFO {
  ULONG          ulcbPhyiscalPacket;
  ULONG          ulcbPhyiscalFrame;
  ULONG          ulcbPhyiscalFrameAlignment;
  REFERENCE_TIME AvgTimePerFrame;
} BDA_TRANSPORT_INFO, *PBDA_TRANSPORT_INFO;

Members

ulcbPhyiscalPacket

Size, in bytes, of a physical packet (for example, the size of a satellite link payload).

ulcbPhyiscalFrame

Size, in bytes, of each physical frame (0 indicates no hardware requirement).

ulcbPhyiscalFrameAlignment

Capture buffer alignment in bytes (0 and 1 indicate no alignment requirements).

AvgTimePerFrame

REFERENCE TIME value that indicates the video frame's average display time, in 100-nanosecond units.

Remarks

A BDA_TRANSPORT_INFO structure in conjunction with a KSDATARANGE structure makes up a KS_DATARANGE_BDA_TRANSPORT data range. A data range describes a range of data formats.

Pins of filters specify the data ranges they support to enable stream connections to pins of other filters that also support those data ranges.
