Field Documentation

uint32_t NvMediaEncodeInitializeParamsH264::enableAllIFrames

Encode all frames as I frames.

Definition at line 2134 of file nvmedia_common.h.

NvMediaBool NvMediaEncodeInitializeParamsH264::enableExternalMEHints

Set to NVMEDIA_TRUE to enable external ME hints.

Currently this feature is not supported if B frames are used

Definition at line 2103 of file nvmedia_common.h.

uint32_t NvMediaEncodeInitializeParamsH264::enableExternalPictureRC

enable external picture rate control

Definition at line 2132 of file nvmedia_common.h.

NvMediaBool NvMediaEncodeInitializeParamsH264::enableLimitedRGB

Set this to NVMEDIA_TRUE for limited-RGB (16-235) input.

Definition at line 2080 of file nvmedia_common.h.

NvMediaBool NvMediaEncodeInitializeParamsH264::enableMVC

If client want to do MVC encoding then this flag need to be set.

Definition at line 2117 of file nvmedia_common.h.

NvMediaBool NvMediaEncodeInitializeParamsH264::enableReconCRC

Enable support for recon CRC generation.

NVMEDIA will allocate extra surface for recon CRC calculation. This can be enabled at run time for any frame by enabling recon CRC and passing recon CRC rectangle.

Definition at line 2115 of file nvmedia_common.h.

NvMediaBool NvMediaEncodeInitializeParamsH264::enableROIEncode

Enable region of interest encoding.

Region of interest encoding parameters are passed with Input extra data parameters

Definition at line 2120 of file nvmedia_common.h.

NvMediaBool NvMediaEncodeInitializeParamsH264::enableSliceEncode

use slice encode to reduce latency in getting encoded buffers.

Definition at line 2122 of file nvmedia_common.h.

NvMediaBool NvMediaEncodeInitializeParamsH264::enableSourceHalfScaled

Enable 2 pass RC with quarter resolution first pass.

Definition at line 2128 of file nvmedia_common.h.

NvMediaBool NvMediaEncodeInitializeParamsH264::enableTwoPassRC

Enable 2 pass RC support.

First pass RC can be run on full or quarter resolution.

Definition at line 2126 of file nvmedia_common.h.

uint32_t NvMediaEncodeInitializeParamsH264::encodeHeight

Holds the encode height.

Definition at line 2078 of file nvmedia_common.h.

uint32_t NvMediaEncodeInitializeParamsH264::encodeWidth

Holds the encode width.

Definition at line 2076 of file nvmedia_common.h.

uint32_t NvMediaEncodeInitializeParamsH264::frameRateDen

Holds the denominator for frame rate used for encoding in frames per second ( Frame rate = frameRateNum / frameRateDen ).

Definition at line 2086 of file nvmedia_common.h.

uint32_t NvMediaEncodeInitializeParamsH264::frameRateNum

Holds the numerator for frame rate used for encoding in frames per second ( Frame rate = frameRateNum / frameRateDen ).

Definition at line 2083 of file nvmedia_common.h.

uint8_t NvMediaEncodeInitializeParamsH264::level

Holds the encoding level.

Client is recommended to set this to NVMEDIA_ENCODE_LEVEL_AUTOSELECT in order to enable the Encode interface to select the correct level.

Definition at line 2094 of file nvmedia_common.h.

NvMediaEncodeExternalMeHintCountsPerBlocktype NvMediaEncodeInitializeParamsH264::maxMEHintCountsPerBlock[2]

If Client wants to pass external motion vectors in NvMediaEncodePicParamsH264 meExternalHints buffer it must specify the maximum number of hint candidates per block per direction for the encode session.

The NvMediaEncodeInitializeParamsH264 maxMEHintCountsPerBlock[0] is for L0 predictors and NvMediaEncodeInitializeParamsH264 maxMEHintCountsPerBlock[1] is for L1 predictors. This client must also set NvMediaEncodeInitializeParamsH264 enableExternalMEHints to NVMEDIA_TRUE.

Definition at line 2110 of file nvmedia_common.h.

uint8_t NvMediaEncodeInitializeParamsH264::maxNumRefFrames

Holds the max reference numbers used for encoding.

Allowed range is [0, 2]. Values:

  • 0 allows only I frame encode
  • 1 allows I and IP encode
  • 2 allows I, IP and IBP encode

Definition at line 2100 of file nvmedia_common.h.

uint32_t NvMediaEncodeInitializeParamsH264::mvcNumViews

Number of views used for MVC.

Definition at line 2130 of file nvmedia_common.h.

uint8_t NvMediaEncodeInitializeParamsH264::profile

Holds the encoding profile.

Client is recommended to set this to NVMEDIA_ENCODE_PROFILE_AUTOSELECT in order to enable the Encode interface to select the correct profile.

Definition at line 2090 of file nvmedia_common.h.

uint32_t NvMediaEncodeInitializeParamsH264::reserved

Add padding.

Definition at line 2136 of file nvmedia_common.h.

uint32_t NvMediaEncodeInitializeParamsH264::useBFramesAsRef

Enables B frames to be used as refernces frames.

Definition at line 2124 of file nvmedia_common.h.
