A shared library of on-demand DeepStream Pipeline Services for Python and C/C++
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 V4L2 Source
uint retval = dsl_source_v4l2_new(L"my-web-cam-1", L"/dev/video0");
from dsl import *
# New V4L2 Source
retval = dsl_source_v4l2_new('my-web-cam-1', '/dev/video0')
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".
The latest releases (v0.28.alpha
and v0.29.alpha
) were developed to support DeepSteam 6.3 and 6.4. However, there are several critical NVIDIA bugs that affect DSL's behavior. We are currently waiting on an ETA for a new DeepStream release (hopefully for NVIDIA GTC 2024 | March 18–21). Issues include:
nvstreammux
and nvstreamdemux
fail to play correctly in DS 6.3
DSL is released under the MIT License. Contributions are welcome and greatly appreciated. Please review our code of conduct.
