Jetpack 4.4 [L4T 32.4.3] customize nvpmodel to make NVENC from 499.2MHz to 729.6MHz

For some reasons, we still need to use Jetpack 4.4 [L4T 32.4.3] for a while…

As mentioned in Release Notes :: NVIDIA JetPack Documentation, we can use 20W NVP mode in Jetson Xavier NX, which can achieve 729.6MHz NVENC following https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3261/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/power_management_jetson_xavier.html#wwpID0E0XO0HA.

How could I customize the nvpmodel that I can use 729.6MHz NVENC under such situation? Then I can check the time cost of nvv4l2h264enc related to How can I customize to use non-blocking mode nvv4l2h264enc

Hi,
Do you use Xavier NX developer kit or your own custom board? The table is for Xavier NX developer kit. For your own custom board, yo would need to use power estimator to customize a mode fitting the board.

We use one “custom board” from GEAC90L系列 - 智能网联 - 天准 _ 工业视觉 | 产业智能

The supplier is upgrading Jetpack to 4.6 from currently 4.4, thus can use the 20W mode, but still need 1-3 months. As a result, I want to see could I just configure the NVENC frequency based on Official NVP Model.

@DaneLLL Hi, any suggestion for our meet?

Hi,
For having 20W modes, we would suggest upgrade to latest release.

OK, thanks and we will have a try.

Maybe my topic is better to make as How to run NVENC in max clock??? following Nvvideoconvert issue, nvvideoconvert in DS4 is better than Ds5? - #3 by DaneLLL

Hi,
There is property in nvv4l2h264enc and nvv4l2h265enc plugins. If you enable it, hardware encoder will run in maximum frequency.

You mean “maxperf-enable=true”? We already configured, but jtop shows we only use it as 499MHz, but as mentioned above, NVENC can achieve 729.6MHz

Hi,
It is maximum clock in 15W modes. 20W modes are enabled and verified in later release. We would suggest upgrade the system.
