| NvMediaEncodeH264BDirectMode NvMediaEncodeConfigH264::bdirectMode |
Holds the BDirect mode.
Definition at line 2021 of file nvmedia_common.h.
| uint8_t NvMediaEncodeConfigH264::disableDeblockingFilterIDC |
Holds the deblocking filter mode.
Permissible value range is [0,2].
Definition at line 2017 of file nvmedia_common.h.
| uint8_t NvMediaEncodeConfigH264::enableWeightedPrediction |
Holds enable weighted prediction.
Definition at line 2075 of file nvmedia_common.h.
| NvMediaEncodeH264EntropyCodingMode NvMediaEncodeConfigH264::entropyCodingMode |
Holds the entropy coding mode.
Definition at line 2023 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::features |
Holds bit-wise OR`ed configuration feature flags.
See enum NvMediaEncodeH264Features.
Definition at line 1999 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::gopLength |
Holds the number of pictures in one GOP.
A low-latency application client can set goplength to NVMEDIA_ENCODE_INFINITE_GOPLENGTH so that keyframes are not inserted automatically.
Definition at line 2003 of file nvmedia_common.h.
| NvMediaEncodeConfigH264VUIParams* NvMediaEncodeConfigH264::h264VUIParameters |
Holds the H.264 video usability information pamameters.
Set to NULL if VUI is not needed.
Definition at line 2056 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::idrPeriod |
Holds the IDR interval.
If not set, the interval is made equal to gopLength. A low-latency application client can set the IDR interval to NVMEDIA_ENCODE_INFINITE_GOPLENGTH so that IDR frames are not inserted automatically.
Definition at line 2012 of file nvmedia_common.h.
| NvMediaEncodeQP NvMediaEncodeConfigH264::initQP |
Holds the initial QP parameters.
The client must set NVMEDIA_ENCODE_CONFIG_H264_INIT_QP in features to use this. QP values must be in the range [1,51].
Definition at line 2068 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::intraRefreshCnt |
Holds the number of frames over which intra refresh happens.
This value must be less than or equal to intraRefreshPeriod. Set to zero to disable intra refresh functionality. If it is set to one, then after every intraRefreshPeriod frames the encoded P frame contains only intra predicted macroblocks. This value is used only if NVMEDIA_ENCODE_CONFIG_H264_ENABLE_INTRA_REFRESH is set in features.
Definition at line 2044 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::intraRefreshPeriod |
Holds the interval between frames that triggers a new intra refresh cycle.
This cycle lasts for intraRefreshCnt frames. This value is used only if 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. Set to zero to suppress triggering of automatic refresh cycles. In this case only NVMEDIA_ENCODE_PIC_TYPE_P_INTRA_REFRESH picture type can trigger a new refresh cycle.
Definition at line 2035 of file nvmedia_common.h.
| NvMediaEncodeQP NvMediaEncodeConfigH264::maxQP |
Holds the maximum QP parameters.
The client must set NVMEDIA_ENCODE_CONFIG_H264_QP_MAX in features to use this. The maximum QP values must be in the range [1,51], and must be greater than NvMediaEncodeRCParams::minQP.
Definition at line 2073 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::maxSliceSizeInBytes |
Holds the maximum slice size in bytes for dynamic slice mode.
The client must set NVMEDIA_ENCODE_CONFIG_H264_ENABLE_DYNAMIC_SLICE_MODE in features to use the maximum slice size in bytes.
Definition at line 2049 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::motionPredictionExclusionFlags |
Holds bitwise OR`ed exclusion flags.
See enum NvMediaEncodeH264MotionPredictionExclusionFlags.
Definition at line 2059 of file nvmedia_common.h.
| uint32_t NvMediaEncodeConfigH264::numMacroblocksPerSlice |
Holds the number of macroblocks per slice.
Set to 0 if a fixed number of macroblocks not required or if maxSliceSizeInBytes or numSliceCountMinus1 is set to a non-zero value.
Definition at line 2053 of file nvmedia_common.h.
| uint16_t NvMediaEncodeConfigH264::numSliceCountMinus1 |
Holds a number that is 1 less than the desire number of slices per frame.
Definition at line 2015 of file nvmedia_common.h.
| NvMediaEncodeH264POCType NvMediaEncodeConfigH264::pocType |
Holds pic_ordec_cnt_type.
Definition at line 2064 of file nvmedia_common.h.
| NvMediaEncodeQuality NvMediaEncodeConfigH264::quality |
Holds the encode quality pre-set.
See enum NvMediaEncodeQuality. Recommended pre-setting is NVMEDIA_ENCODE_QUALITY_L1.
Definition at line 2062 of file nvmedia_common.h.
| NvMediaEncodeRCParams NvMediaEncodeConfigH264::rcParams |
Holds the rate control parameters for the current encoding session.
Definition at line 2005 of file nvmedia_common.h.
| NvMediaEncodeH264SPSPPSRepeatMode NvMediaEncodeConfigH264::repeatSPSPPS |
Holds the frequency of the writing of Sequence and Picture parameters.
Definition at line 2008 of file nvmedia_common.h.
