EncoderRetCode Config(const VmiEncoderConfig &config)

Parameter Description

Struct declarations of VmiEncoderConfig and VmiEncoderParams are as follows:

struct VmiEncoderParams {
    uint32_t bitRate = 3000000;
    uint32_t gopSize = 30;
    uint32_t profile = 1;
    uint32_t keyFrame = 0;
    uint32_t rcMode = 2;                        // Rate control mode
    uint32_t crf = 34;                          // CRF bit rate control level
    uint32_t maxCrfRate = 20000000;             // Maximum CRF bit rate
    int32_t vbvBufferSize = 1000;               // Size of the CRF bit rate buffer
};

struct VmiEncoderConfig {
    uint32_t width = 720;
    uint32_t height = 1280;
    uint32_t frameRate = 30;
    VmiEncoderParams encodeParams;
};

Return Value Description

Data type: EncoderRetCode

The value can be any of the following:

VIDEO_ENCODER_SUCCESS: The encoder is successfully configured.
