Remarks

This DSP changes the frame rate by repeating or dropping frames.

By default, the DSP gets the frame rates from the media types. Optionally, you can specify the frame rates by setting the MFPKEY_CONV_INPUTFRAMERATE and MFPKEY_CONV_OUTPUTFRAMERATE properties. These values override the frame rate given in the media type. However, if you are using this DSP within the Media Foundation pipeline, you should not set these properties.

Requirements

Minimum supported client	Windows Vista
Minimum supported server	Windows Server 2008
Header	Wmcodecdsp.h
