Nvv4l2av1enc questions preset-level + Region Of Interest

Hi,

I have a 2 questions regarding the nvv4l2av1enc:

  • Are there any plans to add support for MediumPreset and LowPreset as preset-level? Our use case only requires 15fps and sometimes only even 7fps. Which mean we basically have 66ms and 142ms of encoding time respectively. The UltraFast and Fast seem to always output for 60fps (<16.6ms). Meaning we are leaving a lot of processing power unused at the moment. Would be nice if we could somehow use this to further improve compression.
  • From what I see there is no support for Region Of Interest (ROI) in the driver of the nvv4l2av1enc? Any plans for this?

Hi,
You are correct about AV1 encoding:

  1. Support ultrafast and fast. Other preset levels are not supported
  2. ROI is not supported

As of now we don’t have plan to add new functions to AV1 encoding on Orin. Please use existing functions.
