: Reserved and must be set to NULL More.Here is a rough guide to tuning the encoder: : Specifies the max temporal layer used for hierarchical coding. : Specifies the H264 video usability info pamameters More. : Specifies the parameter needed for sliceMode. : This parameter in conjunction with sliceModeData specifies the way in which the picture is divided into slices sliceMode = 0 MB based slices, sliceMode = 1 Byte based slices, sliceMode = 2 MB row based slices, sliceMode = 3, numSlices in Picture When forceIntraRefreshWithFrameCnt is set it will have priority over sliceMode setting When sliceMode = 0 and sliceModeData = 0 whole picture will be coded with one slice More. : Specifies the DPB size used for encoding. : Specifies the length of intra refresh in number of frames for periodic intra refresh. : Specifies the interval between successive intra refresh if enableIntrarefresh is set. : Specifies the stereo frame packing mode which is to be signalled in frame packing arrangement SEI More. : Specifies the PPS id of the picture header More. : Specifies the SPS id of the sequence header More. : Specifies max temporal layers to be used for hierarchical coding. : Set to 1 to enable 4:4:4 separate colour planes More. : Reserved bitfields and must be set to 0 More. : Set 1 to enable constrained intra prediction.
: To enable lossless encode set this to 1, set QP to 0 and RC_mode to NV_ENC_PARAMS_RC_CONSTQP and profile to HIGH_444_PREDICTIVE_PROFILE. : Set to 1 to enable LTR (Long Term Reference) frame support. : Set to 1 to enable variable frame rate. : Set to 1 to enable writing of Sequence and Picture parameter for every IDR frame More. : Set this to 1 to enable constrainedFrame encoding where each slice in the constarined picture is independent of other slices Check support for constrained encoding using NV_ENC_CAPS_SUPPORT_CONSTRAINED_ENCODING caps. : Set to 1 to enable gradual decoder refresh or intra refresh. : Set to 1 to enable writing of recovery point SEI message More.
: Set to 1 to enable writing of frame packing arrangement SEI messages to bitstream More. : Set to 1 to disable writing of Sequence and Picture parameter info in bitstream More. : Set to 1 to write access unit delimiter syntax in bitstream More. : Set to 1 to write SEI picture timing syntax in the bitstream. : Set to 1 to write SEI buffering period syntax in the bitstream More. : Set to 1 to enable hierarchical BFrames More. : Set to 1 to enable hierarchical PFrames More.
