Orin nano cannot support hardware encoder. You can try to use the software decoder.

1. Run the script I attached
2. Modify the config file enc: 1 to use software encoder.

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks
