Properties

Property Type Description

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

level?

NvidiaH264Level

(Optional) The target level of this H264 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

number

(Optional) This is somewhat related to the gop structure and again, care should be taken when overriding this from the preset

boolean

(Optional) Output Access Unit Delimiters

preset?

NvidiaPreset

(Optional) The preset to use for this encode

profile?

NvidiaH264Profile

(Optional) The target profile of this H264 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
