MIRACAST_DATARATE_STATS structure (netdispumdddi.h)

Contains info used in the wireless display (Miracast) pfnDataRateNotify function about the audio/video encoder bit rate and failed or retried Wi-Fi frames.

Syntax

typedef struct {
  UINT64 EncoderBitRate;
  UINT64 CurrentMaxTxDataRate;
  UINT64 TransmittedFrameCount;
  UINT64 FailedFrameCount;
  UINT64 RetriedFrameCount;
  UINT64 MultipleRetryFrameCount;
} MIRACAST_DATARATE_STATS;

Members

EncoderBitRate

The bit rate, in bits per second, that the operating system recommends that the audio/video encoder uses.

CurrentMaxTxDataRate

The theoretical maximum speed, in bits per second, reported by the Wi-Fi driver.

TransmittedFrameCount

The total number of Wi-Fi frames that were sent with zero retries since the previous time step.

FailedFrameCount

The total number of Wi-Fi frames that exhausted the maximum number of retries since the previous time step.

RetriedFrameCount

The total number of Wi-Fi frames that succeeded after a single retry since the previous time step.

MultipleRetryFrameCount

The total number of Wi-Fi frames that succeeded after more than one retry since the previous time step.
