MFPKEY_COMPLEXITYEX Property

  • Article

Specifies the encoder algorithm complexity.

Constant for IPropertyBag

g_wszWMVCComplexityEx

Data Type

VT_I4

Default Value

No default value; if no value is set, the codec will use the default for MFPKEY_COMPLEXITY.

Remarks

This integer value ranges from 0 to a maximum value defined by codec. Lower values cause the codec to use less complicated encoding algorithms. Although the simpler algorithms produce lower-quality output, the encoding process is faster and requires less processing power.

This can be important when encoding content from a live source because the encoder must process inputs fast enough to keep up with the source.

Note   Any value assigned to this property will be ignored if the MFPKEY_COMPRESSIONOPTIMIZATIONTYPE property is set to 1. In that case, MFPKEY_COMPLEXITYEX is automatically set to 3.

Applies To

This write-only property is available on the encoder of the following codecs:
