Multimedia API
Computer Vision
Graphics

The Jetson Multimedia API package provides low level APIs for flexible application development.Camera application API: libargus offers a low-level frame-synchronous API for camera applications, with per frame camera parameter control, multiple (including synchronized) camera support, and EGL stream outputs. RAW output CSI cameras needing ISP can be used with either libargus or GStreamer plugin. In either case, the V4L2 mediacontroller sensor driver API is used.Sensor driver API: V4L2 API enables video decode, encode, format conversion and scaling functionality. V4L2 for encode opens up many features like bit rate control, quality presets, low latency encode, temporal tradeoff, motion vector maps, and more.JetPack 5.1.1 Camera highlights include: Support for Multi Point Lens Shading Correction (LSC) on Orin. Enhanced resilience of Argus SyncStereo app to maintain synchronization between stereo camera pairs.JetPack 5.1.1 Multimedia highlights include:Support for dynamic frame rate in AV1 encoding New argus_camera_sw_encode sample for demonstrating software encoding on CPU cores Updated nvgstcapture-1.0 with option of software encoding on CPU cores
VPI (Vision Programing Interface) is a software library that provides Computer Vision / Image Processing algorithms implemented on multiple hardware accelerators found on Jetson such as PVA (Programmable Vision Accelerator), GPU, NVDEC(NVIDIA Decoder), NVENC (NVIDIA Encoder), VIC (Video Image Compositor) and so on.OpenCV is an open source library for computer vision, image processing and machine learning.JetPack 5.1.1 includes a minor update to VPI 2.2 with bug fixes JetPack 5.1.1 includes OpenCV 4.5.4
JetPack 5.1.1 includes the following graphics libraries:Vulkan® 1.3 (including the Roadmap 2022 Profile).Vulkan 1.3 Announcement Vulkan® SC 1.0 Vulkan SC is a low-level, deterministic, robust API that is based on Vulkan 1.2. This API enables state-of-the-art GPU-accelerated graphics and computation that can be deployed in safety-critical systems and that are certified to meet industry functional safety standards. Refer to https://www.khronos.org/vulka nsc/ for more information. Vulkan SC can also be invaluable for real-time non safety critical embedded applications. Vulkan SC increases determinism and reduces application size by shifting preparation of the run-time application environment either offline, or into application setup, as much as possible. This includes offline compilation of graphics pipelines that define how the GPU processes data, together with static memory allocation, that together enable detailed GPU control that can be rigorously specified and tested. Vulkan SC 1.0 is evolved from Vulkan 1.2 and includes: the removal of runtime functionality that is not needed in safety-critical markets, an updated design to provide predictable execution times and results, and clarifications to remove potential ambiguity in its operation. For more details see https://www.khronos.org/blog/vulkan-sc-overview Note: Jetson support for Vulkan SC is not safety certified. OpenWFTM Display 1.0 OpenWF Display is a Khronos API for low overhead interaction with the native display driver on Jetson and allows interaction with Vulkan SC to display images. Note: Jetson support for OpenWF Display is not safety certified.

Triton Inference Server is open source and supports deployment of trained AI models from NVIDIA TensorRT, TensorFlow and ONNX Runtime on Jetson. On Jetson, Triton Inference Server is provided as a shared library for direct integration with C API. PowerEstimator is a webapp that simplifies creation of custom power mode profiles and estimates Jetson module power consumption. etPack 5.1.1 supports PowerEstimator for Jetson AGX Orin and Jetson Xavier NX modules NVIDIA IsaacTM ROS is a collection of hardware- accelerated packages that make it easier for ROS developers to build high- performance solutions on NVIDIA hardware including NVIDIA Jetson. Isaac ROS DP3 release supports JetPack 5.1.1
Jetson brings Cloud-Native to the edge and enables technologies like containers and container orchestration. NVIDIA JetPack includes NVIDIA Container Runtime with Docker integration, enabling GPU accelerated containerized applications on Jetson platform. NVIDIA hosts several container images for Jetson on NVIDIA NGC. Some are suitable for software development with samples and documentation and others are suitable for production software deployment, containing only runtime components. Find more information and a list of all container images at the Cloud-Native on Jetson page.
NVIDIA Jetson modules include various security features including Hardware Root of Trust, Secure Boot, Hardware Cryptographic Acceleration, Trusted Execution Environment, Disk and Memory Encryption, Physical Attack Protection and more. Learn about the security features by jumping to the security section of the Jetson Linux Developer guide.
