Windows Media Encoder SDK banner art

The AverageSampleRate property retrieves the average number of media samples encoded per second since the encoding session was started.

Syntax

Long = IWMEncOutputStats.AverageSampleRate

Parameters

This property takes no parameters.

Property Value

A Long containing the average sample rate in samples per second.

Remarks

This property is read-only.

Example Code

' Create a WMEncoder object.
Dim Encoder As WMEncoder
Set Encoder = New WMEncoder

' Retrieve an IWMEncStatistics object.
Dim Stats As IWMEncStatistics
Set Stats = Encoder.Statistics

' You must manually configure the encoding session or load
' a configuration from a file. For an example, see the
' IWMEncFile object.

' Retrieve an IWMEncOutputStats object from the
' IWMEncStatistics object.
Dim OutputStats As IWMEncOutputStats
Set OutputStats = Stats.StreamOutputStats(WMENC_AUDIO, 0, 0)

' You can create a timer control to retrieve the statistics
' (as follows) after you start the encoding session.

Dim lExpectedBitRate As Long
Dim lExpectedSampleRate As Long
Dim lSampleCount As WMENC_LONGLONG
