| uint32_t NvMediaEncodePicParamsH265::frameRateDen |
Holds the numerator for frame rate used for encoding in frames per second ( Frame rate = frameRateNum / frameRateDen ).
Definition at line 2491 of file nvmedia_common.h.
| uint32_t NvMediaEncodePicParamsH265::frameRateNum |
Holds the numerator for frame rate used for encoding in frames per second ( Frame rate = frameRateNum / frameRateDen ).
Definition at line 2488 of file nvmedia_common.h.
| NvMediaEncodeExternalMEHint* NvMediaEncodePicParamsH265::meExternalHints |
Holds the pointer to ME external hints for the current frame.
The size of ME hint buffer must be equal to number of macroblocks multiplied by the total number of candidates per macroblock. The total number of candidates per MB per direction =
1*meHintCountsPerBlock[Lx].numCandsPerBlk16x16 + 2*meHintCountsPerBlock[Lx].numCandsPerBlk16x8 + 2*meHintCountsPerBlock[Lx].numCandsPerBlk8x16 + 4*meHintCountsPerBlock[Lx].numCandsPerBlk8x8
For frames using bidirectional ME, the total number of candidates for a single macroblock is the sum of the total number of candidates per MB for each direction (L0 and L1).
If no external ME hints are needed, set this field to NULL.
Definition at line 2485 of file nvmedia_common.h.
| NvMediaEncodeExternalMeHintCountsPerBlocktype NvMediaEncodePicParamsH265::meHintCountsPerBlock[2] |
Holds the number of hint candidates per block per direction for the current frame.
meHintCountsPerBlock[0] is for L0 predictors and meHintCountsPerBlock[1] is for L1 predictors. The candidate count in NvMediaEncodePicParamsH265 meHintCountsPerBlock[lx] must never exceed NvMediaEncodeInitializeParamsH265 maxMEHintCountsPerBlock[lx] provided during encoder intialization.
Definition at line 2469 of file nvmedia_common.h.
| uint32_t NvMediaEncodePicParamsH265::nextBFrames |
Secifies the number of B-frames that follow the current frame.
This number can be set only for reference frames and the frames that follow the current frame must be nextBFrames count of B-frames. B-frames are supported only if the profile is greater than NVMEDIA_ENCODE_PROFILE_BASELINE and the maxNumRefFrames is set to 2. Set to zero if no B-frames are needed.
Definition at line 2453 of file nvmedia_common.h.
| NvMediaEncodePicType NvMediaEncodePicParamsH265::pictureType |
Holds input picture type.
Definition at line 2444 of file nvmedia_common.h.
| NvMediaEncodeRCParams NvMediaEncodePicParamsH265::rcParams |
Holds the rate control parameters from the current frame onward if the NVMEDIA_ENCODE_PIC_FLAG_RATECONTROL_CHANGE is set in the encodePicFlags.
Please note that the rateControlMode cannot be changed on a per frame basis only the associated rate control parameters.
