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.

#include <DslApi.h>

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

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 is released under the MIT License. Contributions are welcome and greatly appreciated. Please review our code of conduct.
