Permissible value range: [0,2].
Definition at line 2006 of file nvmedia_common.h.
| uint8_t NvMediaEncodeConfigH264::enableWeightedPrediction |
Holds enable weighted predition.
Definition at line 2056 of file nvmedia_common.h.
| NvMediaEncodeH264EntropyCodingMode NvMediaEncodeConfigH264::entropyCodingMode |
Holds the entropy coding mode.
Definition at line 2012 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::features |
Holds bit-wise OR`ed configuration feature flags.
See NvMediaEncodeH264Features enum
Definition at line 1990 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::gopLength |
Holds the number of pictures in one GOP.
Low latency application client can set goplength to NVMEDIA_ENCODE_INFINITE_GOPLENGTH so that keyframes are not inserted automatically.
Definition at line 1994 of file nvmedia_common.h.
| NvMediaEncodeConfigH264VUIParams* NvMediaEncodeConfigH264::h264VUIParameters |
Holds the H264 video usability info pamameters.
Set to NULL if VUI is not needed
Definition at line 2039 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::idrPeriod |
Holds the IDR interval.
If not set, this is made equal to gopLength in NvMediaEncodeConfigH264. Low latency application client can set IDR interval to NVMEDIA_ENCODE_INFINITE_GOPLENGTH so that IDR frames are not inserted automatically.
Definition at line 2002 of file nvmedia_common.h.
| NvMediaEncodeQP NvMediaEncodeConfigH264::initQP |
Holds Initial QP parameters.
Client must set NVMEDIA_ENCODE_CONFIG_H264_INIT_QP in features to use this. QP values should be within the range of 1 to 51
Definition at line 2049 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::intraRefreshCnt |
Holds the number of frames over which intra refresh will happen.
This value must be less than or equal to intraRefreshPeriod. Setting it to zero turns off the intra refresh functionality. Setting it to one essentially means that after every intraRefreshPeriod frames the encoded P frame contains only intra predicted macroblocks. This value is used only if the NVMEDIA_ENCODE_CONFIG_H264_ENABLE_INTRA_REFRESH is set in features.
Definition at line 2030 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::intraRefreshPeriod |
Holds the interval between frames that trigger a new intra refresh cycle and this cycle lasts for intraRefreshCnt frames.
This value is used only if the NVMEDIA_ENCODE_CONFIG_H264_ENABLE_INTRA_REFRESH is set in features. NVMEDIA_ENCODE_PIC_TYPE_P_INTRA_REFRESH picture type also triggers a new intra refresh cycle and resets the current intra refresh period. Setting it to zero results in that no automatic refresh cycles are triggered. In this case only NVMEDIA_ENCODE_PIC_TYPE_P_INTRA_REFRESH picture type can trigger a new refresh cycle.
Definition at line 2022 of file nvmedia_common.h.
| NvMediaEncodeQP NvMediaEncodeConfigH264::maxQP |
Holds maximum QP parameters.
Client must set NVMEDIA_ENCODE_CONFIG_H264_QP_MAX in features to use this. The maximum QP values must be within the range of 1 to 51 and must be greater than NvMediaEncodeRCParams::minQP.
Definition at line 2054 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::maxSliceSizeInBytes |
Holds the max slice size in bytes for dynamic slice mode.
Client must set NVMEDIA_ENCODE_CONFIG_H264_ENABLE_DYNAMIC_SLICE_MODE in features to use max slice size in bytes.
Definition at line 2034 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::motionPredictionExclusionFlags |
Holds bit-wise OR`ed exclusion flags.
See NvMediaEncodeH264MotionPredictionExclusionFlags enum.
Definition at line 2041 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::numMacroblocksPerSlice |
Number of macroblocks per slice.
Set to 0 if fix number of macroblocks not required or maxSliceSizeInBytes or numSliceCountMinus1 is set to non-zero value.
Definition at line 2037 of file nvmedia_common.h.
| uint16_t NvMediaEncodeConfigH264::numSliceCountMinus1 |
Holds a number that is 1 less than the number of slices desired per frame.
Definition at line 2004 of file nvmedia_common.h.
| NvMediaEncodeH264POCType NvMediaEncodeConfigH264::pocType |
Holds pic_ordec_cnt_type.
Definition at line 2046 of file nvmedia_common.h.
| NvMediaEncodeQuality NvMediaEncodeConfigH264::quality |
Holds encode quality pre-set.
See NvMediaEncodeQuality enum. Recommended pre-setting is NVMEDIA_ENCODE_QUALITY_L1.
Definition at line 2044 of file nvmedia_common.h.
| NvMediaEncodeRCParams NvMediaEncodeConfigH264::rcParams |
Holds the rate control parameters for the current encoding session.
Definition at line 1996 of file nvmedia_common.h.
| NvMediaEncodeH264SPSPPSRepeatMode NvMediaEncodeConfigH264::repeatSPSPPS |
Holds the frequency of the writing of Sequence and Picture parameters.
Definition at line 1998 of file nvmedia_common.h.
