Definition at line 1577 of file nvmedia_common_encode.h.
◆ error_resilient
| NvMediaBool NvMediaEncodeConfigVP9::error_resilient |
Set the feature flag NVMEDIA_ENCODE_CONFIG_VP9_DISABLE_ERROR_RESILIENT to set the following parameter.
Enable Error resiliency. This is for setting the feature flag NVMEDIA_ENCODE_CONFIG_VP9_DISABLE_ERROR_RESILIENT.
Definition at line 1608 of file nvmedia_common_encode.h.
◆ features
| uint32_t NvMediaEncodeConfigVP9::features |
Holds bit-wise OR`ed configuration feature flags.
