tagBDA_TRANSPORT_INFO structure

Description

The BDA_TRANSPORT_INFO structure describes formatting for a stream connection.

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.
