TRANSPORT_SAMPLE_STATISTICS Structure

[This documentation is preliminary and is subject to change.]

Contains statistics collected by the output pins of the MPEG-2 Demultiplexer.

Syntax

typedef struct _TransportSampleStatistics {
  DWORD dwWindowSize;
  DWORD dwNoOfRunningPackets;
  DWORD dwNoOfScrambledPackets;
  DWORD dwNoOfDiscontinuity;
  DWORD dwNoOfDroppedPackets;
  REFERENCE_TIME rtCurrentStreamTime;
  REFERENCE_TIME rtFirstPacketStreamTime;
  REFERENCE_TIME rtLastPacketStreamTime;
  REFERENCE_TIME rtLastDemuxInputSampleTime;
} TRANSPORT_SAMPLE_STATISTICS;

Members

• dwWindowSize
  The maximum number of packets for which the pin stores a running count of statistical data. Once this number is exceeded, the pin discards information using a first-in, first-out (FIFO) queue.

• dwNoOfRunningPackets
  The running count of packets.

• dwNoOfScrambledPackets
  The number of scrambled packets.

• dwNoOfDiscontinuity
  The number of discontinuities.

• dwNoOfDroppedPackets
  The number of dropped packets.

• rtCurrentStreamTime
  The current stream time.

• rtFirstPacketStreamTime
  The stream time of the earliest packet listed in the statistical data.

• rtLastPacketStreamTime
  The stream time of the latest packet listed in the statistical data.

• rtLastDemuxInputSampleTime
  The stream time of the most recent packet received by the MPEG-2 filter.
