Intelligent Audio and Video Analytics (IAVA)

A library of on-demand DeepStream Pipeline services. Written in C++ 17 with an extern "C" API, The DeepStream Services Library (DSL) can be called from both C/C++ and Python applications.

Examples

C++

#include <DslApi.h>

// New CSI Live Camera Source
uint retval = dsl_source_csi_new("csi-source", 1280, 720, 30, 1);

Python3

from dsl import *

# New CSI Live Camera Source
retval = dsl_source_csi_new('csi-source', 1280, 720, 30, 1)

DSL is built on the NVIDIA® DeepStream SDK, "A complete streaming analytics toolkit for AI-based video and image understanding, as well as multi-sensor processing.",

The DeepStream SDK and DSL use the open source GStreamer,  "An extremely powerful and versatile framework for creating streaming media applications".

DSL Branching Workflow

1. Master is always the latest release and is only updated once per release.
2. Develop is the next release currently in development. The branch will be named with the next release label.
3. Feature all work is done on feature branches, named for the feature under development.

All pull requests should be made against the current Develop branch.

Docker

The deepstream-services-library-docker repo contain a Dockerfile, utility scripts, and instructions to create and run a DSL-DeepStream container, built with the nvcr.io/nvidia/deepstream-l4t:6.0-triton base image (Jetson).
