This property is read/write.

Property value

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


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.
