DeepStream is a GStreamer-based SDK for creating vision AI applications with AI for image processing and object detection. DeepStream 6.3 introduces Graph eXecution Format (GXF), a framework that supports multiple clock domains and brings GPU-accelerated state machines.

Release Highlights

Release notes

DeepStream 6.3 Highlights:

  • New multi-arch containers, including both x86 and NVIDIA Jetson™
  • Four additional plug-ins now available in source-code format
  • Support for MQTT protocol (metadata out)
  • New REST-APIs to control DeepStream pipeline on-the-fly
  • New Google protobuf support
  • DeepStream tracker Re-ID embeddings now available as metadata
  • Multiple video decoder improvements
  • Preprocessing plug-in that adds NVIDIA Triton™ support

GXF and Graph Composer 3.0 Highlights:

  • New Python and C++ APIs
  • Event-triggered data-out support
  • New GXF distributed execution option with UCX support
  • New data formats supported by GXF (Bayer, RAW16, and 3D RGBD)
  • Support for multiple clock sources
  • Remote server for Graph Composer
  • Improvements to Graph Composer sub-graphs

For full details, check the new NGC Collection page and the DeepStream 6.3 Release notes.


Please note that with the DeepStream 6.3 release, the number and type of available containers has changed. There are three types of containers:

  • Triton: This is a new single container for both x86 and Jetson.
  • Samples: No changes from previous release. One container for X86 and one container for Jetson.
  • Development: This container is x86 only, including Graph Composer.

For full details, check the new NGC Collection page.

Product Advisory

If you’re planning to bring models that use an older version of NVIDIA® TensorRT™ (, make sure you regenerate the INT8 calibration cache before using them with DeepStream 6.3.

You can find details regarding regenerating the cache in the Read Me First section of the documentation. For new DeepStream developers or those not reusing old models, this step can be omitted.

Ethical AI
NVIDIA platforms and application frameworks enable developers to build a wide array of AI applications. Consider potential algorithmic bias when choosing or creating the models being deployed. Also, work with the model’s developer to ensure that it meets the requirements for the relevant industry and use case; that the necessary instruction and documentation are provided to understand error rates, confidence intervals, and results; and that the model is being used under the conditions and in the manner intended.
