Specifies whether the complexity of the audio encoding algorithm is constrained.
Constant for IPropertyBag
Available only by using IPropertyStore.
If you leave this property at its default value of VARIANT_FALSE, the audio encoder uses its default algorithm. The default algorithm depends on the output type and which version of Windows is running. The following table describes the default behavior for the different combinations.
|Operating system||Default behavior|
|Windows Vista||For all output types, the audio encoder uses the most complex algorithm by default.|
|Windows 7||For Standard and Professional output types, the audio encoder uses the most complex algorithm by default. For Lossless output types, the audio encoder uses the least complex algorithm by default.|
If you set this property to VARIANT_TRUE, you must also specify a complexity value by setting the MFPKEY_ENCCOMPLEXITY property.
