AVEncCommonMeanBitRateInterval property
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
Specifies the time interval over which the average bit rate applies. This property is used in conjunction with the AVEncCommonMeanBitRate property.
This property is read/write.
Data type
UINT64 (VT_UI8)
Property GUID
CODECAPI_AVEncCommonMeanBitRateInterval
Property value
This property has a linear range of values. To get the supported range, call ICodecAPI::GetParameterRange.
Remarks
For two-pass variable bit rate (VBR) encoding, the value zero indicates that the time interval is the entire duration of the content. For single-pass constant bit rate (CBR) encoding, the value zero indicates that the encoder selects the interval (typically 0.5 seconds).
