Hi Nvidia，

  1. I did not call the setHWPresetType function in my code to set the encoder preset. How does the encoder balance encoding speed and video quality in this case?

  2. What is the difference between V4L2_ENC_HW_PRESET_DISABLE and V4L2_ENC_HW_PRESET_DEFAULT?

  3. What is the difference between v4l2_enc_hw_preset_type and v4l2_enc_hw_tuning_info_type?

Hi,
Please always configure hardware preset as suggested in
What is the default value of HW preset - #4 by DaneLLL

v4l2_enc_hw_tuning_info_type is not supported on Orin series. Please always set v4l2_enc_hw_preset_type
