Detailed Description#

Different parameters for CUDA video encoder.

Constructor & Destructor Documentation#

EncoderParams()#

cv::cudacodec::EncoderParams::EncoderParams()

Member Data Documentation#

averageBitRate#

int cv::cudacodec::EncoderParams::averageBitRate

target bitrate for ENC_PARAMS_RC_VBR and ENC_PARAMS_RC_CBR.

constQp#

EncodeQp cv::cudacodec::EncoderParams::constQp

QP’s for ENC_PARAMS_RC_CONSTQP.

encodingProfile#

EncodeProfile cv::cudacodec::EncoderParams::encodingProfile

gopLength#

int cv::cudacodec::EncoderParams::gopLength

the number of pictures in one GOP, ensuring idrPeriod >= gopLength.

idrPeriod#

int cv::cudacodec::EncoderParams::idrPeriod

IDR interval, ensuring idrPeriod >= gopLength.

maxBitRate#

int cv::cudacodec::EncoderParams::maxBitRate

upper bound on bitrate for ENC_PARAMS_RC_VBR and ENC_PARAMS_RC_CONSTQP.

multiPassEncoding#

EncodeMultiPass cv::cudacodec::EncoderParams::multiPassEncoding

nvPreset#

EncodePreset cv::cudacodec::EncoderParams::nvPreset

rateControlMode#

EncodeParamsRcMode cv::cudacodec::EncoderParams::rateControlMode

targetQuality#

uint8_t cv::cudacodec::EncoderParams::targetQuality

value 0 - 51 where video quality decreases as targetQuality increases, used with ENC_PARAMS_RC_VBR.

tuningInfo#

EncodeTuningInfo cv::cudacodec::EncoderParams::tuningInfo

videoFullRangeFlag#

bool cv::cudacodec::EncoderParams::videoFullRangeFlag

Indicates if the black level, luma and chroma of the source are represented using the full or limited range (AKA TV or “analogue” range) of values as defined in Annex E of the ITU-T Specification.
