Data Type

UINT32 (VT_UI4)

Possible Values

This property has a linear range of values. To get the supported range, call ICodecAPI::GetParameterRange.

Remarks

This property is read/write.

The property is available only if the encoding duration is defined in advance, using the AVEncVideoNoOfFieldsToEncode property or AVEncAudioIntervalToEncode property.

For MPEG video, this property defines the video buffer verifier (VBV) fullness at the end of the encoding process. It supports the concatenation of streams during encoding.
