AVEncVideoOutputFrameRate property

Specifies the frame rate on the encoder's output stream, in frames per second.

This property is read/write.

Data type

UINT64 (VT_UI8)

Property GUID

CODECAPI_AVEncVideoOutputFrameRate

Property value

The value of this property is a ratio that defines the frame rate. The upper 32 bits contain the numerator, and the lower 32 bits contain the denominator. The following table shows common frame rates, in frames per second.

Frame rateRatio
23.9724000/1001
2424/1
2525/1
29.9730000/1001
3030/1
5050/1
59.9460000/1001
6060/1

 

Remarks

Applications can set this property to specify the output frame rate. Encoders can also return this property as a capability. Depending on the encoder, the value might be restricted to the input frame rate. If not, the encoder is able to convert the frame rate internally. See AVEncVideoOutputFrameRateConversion Property.

This property is also used with H.264 UVC 1.5 camera encoders.
