MFPKEY_COMPLEXITYEX Property
Specifies the encoder algorithm complexity.
Constant for IPropertyBag
g_wszWMVCComplexityEx
Data Type
VT_I4
Default Value
The default value depends on the version of the video encoder, as shown in the following table.
| Encoder version | Default value |
|---|---|
| Windows Media Video 9 encoder | 3 |
| Windows Media Video 7/8 encoder | 1 |
Possible Values
The possible values depend on the version of the video encoder, as shown in the following table.
| Encoder version | Possible values |
|---|---|
| Windows Media Video 9 encoder | 0, 1, 2, 3, 4, 5 |
| Windows Media Video 7/8 encoder | 0, 1 |
Remarks
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.
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.
