Hi,

Currently Iā€™m using NvVideoEncoder based on V4L2 on Orin, and Iā€™m trying to understand how to implement a-relatively-similar encoding pipeline on Drive-AGX-Orin, but finding it hard to find any documentation explaining how to encode video using NvMedia API

Thanks.

Please take a look at Image Encode Processing (IEP) and
NvMedia IEP ā€“ Encode Processing (nvm_iep_sci).

Thanks,

Iā€™ve already seen these guides, but what is not clear to me is that I donā€™t see the ā€œnvm_iep_sciā€ application nor its source code anywhere on the Orin.

Moreover, it does seem to have some of the example applications.
Under: ā€˜/opt/nvidia/drive-linux/NVIDIA_CUDA-11.4_Samplesā€™
Thereā€™re:

1_Utilities
2_Graphics
3_Imaging
4_Finance
5_Simulations
6_Advanced
7_CUDALibraries
EULA.txt
Makefile
common
libnvmedia_iep_sci.so

Which DRIVE OS version are you using?

5

DriveOS 6.0.5
(with DriveWorks 5.8)

6

Please read through Building and Running the NvMedia Samples | NVIDIA Docs. The source is on your host system.

Since Iā€™m using a different host, I downloaded DriveOS 6.0.5 (host: ubuntu 20.04) and ran the installation - still, I have the folder DRIVE_OS_6.0.5_SDK_Linux_DRIVE_AGX_ORIN_DEVKITS, but the expected video encoder and decoder are nowhere to be found.
Can you specify the exact process of getting these samples from the SDK?
There are several other samples sources, but none of them are video related.

I wonā€™t lie - this really feels like Nvidia just doesnā€™t want developers to use DriveOS for video encodingā€¦

You should be able to find them under the directory.

~/nvidia/nvidia_sdk/DRIVE_OS_6.0.5_SDK_Linux_DRIVE_AGX_ORIN_DEVKITS/DRIVEOS/drive-linux/samples/nvmedia_6x/

9

This might be the problem - under ā€œ~/nvidia/nvidia_sdk/DRIVE_OS_6.0.5_SDK_Linux_DRIVE_AGX_ORIN_DEVKITS/DRIVEOS/drive-linux/samples/ā€, thereā€™s only vulkan-sc-samples/

10

How did you install DRIVE OS 6.0.5? followed DRIVE OS 6.0.5 Installation Guide for NVIDIA Developers? with SDK Manager or Docker?

11

I used SDK manager installed on ubuntu 20.04.
Installed DRIVE with Host Machine marked and Target Hardware = Drive AGX Orix DevKit.
Selected Operating System = DRIVEU OS 6.0.5 SDK

12

Dear @yoav10,
Is it possible to reinstall DRIVE OS 6.0.5 on host and target? We expect the samples to be under the direcory Vick mentioned.
