Specifies whether the encoder is constrained by a maximum decoder latency requirement.
Constant for IPropertyBag
Available only by using IPropertyStore.
If you leave this property at its default value of VARIANT_FALSE, the encoder enumerates a default set of modes that have about 1500 milliseconds of decoder latency. If you set this property to VARIANT_TRUE, you must also specify a maximum decoder latency by setting the MFPKEY_MAXDECLATENCYMS property. In that case, the encoder creates modes that satisfy the latency requirement and enumerates only those modes. The encoder ensures that the preroll requirements (decoder buffer size) are less than or equal to MFPKEY_MAXDECLATENCYMS.
