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.
