Jetson NVENC Spatial AQ

[henrik.engstrom]

Hi, is it possible to enable Spatial AQ for Jetson/NVENC?

For the desktop API can use:
NV_ENC_INITIALIZE_PARAMS::encodeconfig->rcParams. enableAQ
NV_ENC_INITIALIZE_PARAMS::encodeconfig->rcParams.aqStrength

Hi,
The parameters are not supported on Jetson platforms. The paramters of external rate control is different. For further information, please check populate_ext_rate_ctrl_Param() in the sample:

/usr/src/jetson_multimedia_api/samples/01_video_encode

Hi, thanks for the quick response. I found this topic where it is mentioned that you are working on unifying dGPU and Jetson interfaces. Will Spatial AQ be available later on? If so, do you have an estimation of when?

How does Jetson NVENC compare with Desktop NVENC?

Hi, The design of hardware codec was different between dGPU and Jetson chips, so we have individual software stacks for each platform. Now hardware design is identical and we are unifying the interface. It is underway and this would take some time. So as of now, please follow the jetson_multimedia_api samples to develop your use-cases. The document for jetson_multimedia_api is Jetson Linux API Reference: Main Page | NVIDIA Docs For setting preset level, please refer to the function in NvVide…

I’m also interested in the follow-up question by Henrik; is there a time frame for when the NVENC APIs will be the single software stack for both desktop and Jetson? And will the feature set be the same, like e.g. Spatial AQ?

Hi,
For Jetson Orin series, we will not have new parameters. We will evaluate it for Jetson Thor.
