CODECAPI_AVEncVideoEncodeQP property
Specifies the quantization parameter (QP) for video encoding.
Data type
ULONGLONG (VT_UI8)
Property GUID
CODECAPI_AVEncVideoEncodeQP
Property value
A set of four 16-bit fields used to specify the frame QPs in fixed-QP encoding.
The fields are:
- Bits 0-15: Default QP
- Bits 16-31: QP used for I frames
- Bits 32-47: QP used for P frames
- Bits 48-63: QP used for B frames
Remarks
This property is also used with H.264 UVC 1.5 camera encoders.
To insure consistent usage across different encoders, you should assume encoders will only look at the default QP and can ignore QP values for I/P/B pictures.
