MFPKEY_BAVG Property
Specifies the buffer window, in milliseconds, of a constrained variable-bit-rate (VBR) stream at its average bit rate (specified by MFPKEY_RAVG).
Constant for IPropertyBag
g_wszWMVCBAvg
Data Type
VT_I4
Default Value
No default value, but the codec will compute an appropriate value based on the other constrained VBR settings.
Remarks
This value is computed by the codec after the final encoding pass. You should not query for this value until after encoding is complete. The codec interprets a request for this value as a signal that the encoding session is over; the next sample that you process is treated as the beginning of a new session.
