MFPKEY_COMPLEXITY Property

Specifies the encoder algorithm complexity.

Constant for IPropertyBag

g_wszWMVCComplexityMode

Data Type

VT_I4

Default Value

2

Remarks

This integer value ranges from 0 to 3. 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This property is superseded by MFPKEY_COMPLEXITYEX, which should be used for new content. However, not all encoding tools use the new property yet.

Applies To

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

• Windows Media Video 9
• Windows Media Video 9 Advanced Profile

Requirements

Client: Requires Windows Vista or Windows XP.

Header: Include wmcodecdsp.h.
