Properties

Property Type Description

enableIntraRefresh?

boolean

(Optional) Enable Gradual Decoder Refresh (intra-refresh): refresh the picture with a moving wave of intra blocks instead of periodic IDR frames.

frameIntervalP?

number

(Optional) This is the gop structure to be used, and again it’s best to look this up in the Nvidia documentation

gopInterval?

number

(Optional) The gopInterval to use for this encode Note: This is different from the idrPeriod but usually you want them set to the same value regardless

idrPeriod?

number

(Optional) The IDR period

intraRefreshCnt?

number

(Optional) Number of frames over which a single intra-refresh wave completes.

intraRefreshPeriod?

number

(Optional) Period in frames between the start of successive intra-refresh waves.

level?

NvidiaHevcLevel

(Optional) The target level of this HEVC encode Note: The behaviour of Nvidia is to error out if this is incompatible with the other settings this differs from other codecs which just silently change the outgoing level/profile for example

outputAud?

boolean

(Optional) Output Access Unit Delimiters

preset?

NvidiaPreset

(Optional) The preset to use for this encode

profile?

NvidiaHevcProfile

(Optional) The target profile of this HEVC encode Note: The behaviour of Nvidia is to error out if this is incompatible with the other settings this differs from other codecs which just silently change the outgoing level/profile for example

rateControl?

NvidiaRateControl

(Optional) Rate Control Settings

tier?

NvidiaHevcTier

(Optional) The target tier of this HEVC encode Note: The behaviour of Nvidia is to error out if this is incompatible with the other settings this differs from other codecs which just silently change the outgoing level/profile for example
