MFPKEY_BMAX Property
Specifies the buffer window, in milliseconds, of a constrained variable-bit-rate (VBR) stream at its peak bit rate (specified by MFPKEY_RMAX).
Constant for IPropertyBag
g_wszWMVCBMax
Data Type
VT_I4
Default Value
No default.
Remarks
You must set this value for peak-constrained VBR encoding. After you begin processing samples, you must not query for this value until you are finished encoding the stream. 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.
