This is for setting the feature flag NVMEDIA_ENCODE_CONFIG_VP9_ENABLE_QUANTIZATION_PARAMS.
Definition at line 1253 of file nvmedia_common_encode.h.
◆ bmode_ref_lf_delta_enabled
| NvMediaBool NvMediaEncodeConfigVP9::bmode_ref_lf_delta_enabled |
Set it to true if MB-level loop filter adjustment is on.
Definition at line 1245 of file nvmedia_common_encode.h.
◆ bmode_ref_lf_delta_update
| NvMediaBool NvMediaEncodeConfigVP9::bmode_ref_lf_delta_update |
Set it to true if MB-level loop filter adjustment delta values are updated.
Definition at line 1247 of file nvmedia_common_encode.h.
◆ delta_uv_ac
| int32_t NvMediaEncodeConfigVP9::delta_uv_ac |
Specifies qindex adjustment for uv dccoefficient, -15...15.
This is for setting the feature flag NVMEDIA_ENCODE_CONFIG_VP9_ENABLE_QUANTIZATION_PARAMS.
Definition at line 1262 of file nvmedia_common_encode.h.
◆ delta_uv_dc
| int32_t NvMediaEncodeConfigVP9::delta_uv_dc |
Specifies qindex adjustment for uv accoefficient, -15...15.
This is for setting the feature flag NVMEDIA_ENCODE_CONFIG_VP9_ENABLE_QUANTIZATION_PARAMS.
Definition at line 1259 of file nvmedia_common_encode.h.
◆ delta_y_dc_q
| int32_t NvMediaEncodeConfigVP9::delta_y_dc_q |
Specifies explicit qindex adjustment for y dccoefficient, -15...15.
This is for setting the feature flag NVMEDIA_ENCODE_CONFIG_VP9_ENABLE_QUANTIZATION_PARAMS.
Definition at line 1256 of file nvmedia_common_encode.h.
◆ error_resilient
| NvMediaBool NvMediaEncodeConfigVP9::error_resilient |
Enable Error resiliency.
This is for setting the feature flag NVMEDIA_ENCODE_CONFIG_VP9_DISABLE_ERROR_RESILIENT.
Definition at line 1281 of file nvmedia_common_encode.h.
◆ features
| uint32_t NvMediaEncodeConfigVP9::features |
Holds bit-wise OR`ed configuration feature flags.
TBD
Definition at line 1218 of file nvmedia_common_encode.h.
◆ filter_level
| uint32_t NvMediaEncodeConfigVP9::filter_level |
Specifies the loop filter strength for each segment.
Definition at line 1236 of file nvmedia_common_encode.h.
◆ filter_type
| uint32_t NvMediaEncodeConfigVP9::filter_type |
Set the feature flag NVMEDIA_ENCODE_CONFIG_VP9_ENABLE_LOOP_FILTER_PARAMS to change the following parameters.
Specifies the type of the filter used. :0 eight-tap smooth, 1: eight-tap, 2: eight-tap sharp, 3: bilinear, 4: switchable
Definition at line 1234 of file nvmedia_common_encode.h.
◆ gopLength
| uint32_t NvMediaEncodeConfigVP9::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.

◆ idrPeriod
| uint32_t NvMediaEncodeConfigVP9::idrPeriod |
Holds the IDR interval.
If not set, this is made equal to gopLength in NvMediaEncodeConfigVP9. Low-latency application client can set IDR interval to NVMEDIA_ENCODE_INFINITE_GOPLENGTH so that IDR frames are not inserted automatically.
Definition at line 1228 of file nvmedia_common_encode.h.
◆ initQP
| NvMediaEncodeQP NvMediaEncodeConfigVP9::initQP |
Holds Initial QP parameters.
Client must set NVMEDIA_ENCODE_CONFIG_VP9_INIT_QP in features to use this. QP values should be within the range of 1 to 255
Definition at line 1285 of file nvmedia_common_encode.h.
◆ maxQP
| NvMediaEncodeQP NvMediaEncodeConfigVP9::maxQP |
Holds maximum QP parameters.
Client must set NVMEDIA_ENCODE_CONFIG_VP9_QP_MAX in features to use this. The maximum QP values must be within the range of 1 to 255 and must be set to a value greater than NvMediaEncodeRCParams::minQP.
Definition at line 1290 of file nvmedia_common_encode.h.
