CODECAPI_AVEncVideoForceKeyFrame property
Forces the encoder to code the next frame as a key frame.
Data type
ULONG (VT_UI4)
Property GUID
CODECAPI_AVEncVideoForceKeyFrame
Property value
If the value is nonzero, the encoder will code the next frame as a key frame. If the value is zero, the encoder selects whether to encode the next frame as a key frame.
This property applies to the next frame that the encoder receives as input. For a Media Foundation transform (MFT), this is the next frame that is passed to the IMFTransform::ProcessInput method. The setting resets to zero after the next frame.
Remarks
This property is also used with H.264 UVC 1.5 camera encoders.
