Details of Setup

  • Hardware Platform (Jetson / GPU): GPU
  • DeepStream Version: 7.1.0
  • TensorRT Version: 10.7.0.23-1+cuda12.6 amd64
  • NVIDIA GPU Driver Version (valid for GPU only): 560.35.03 (CUDA Version: 12.6)

Issue Type: Bug

Description of Issue:

During the startup of DeepStream, an error is observed in the loading of the libgstmsdk.so plugin located at /usr/lib/x86_64-linux-gnu/gstreamer-1.0/. The logs initially indicate that the plugin has been loaded successfully, but soon after, there are errors related to file descriptor (fd) operations and the plugin is subsequently blacklisted.

Have you installed the Intel Media SDK? If you don’t install the Intel Media SDK, the plugin will not work properly.

In addition, this problem is not related to DeepStream. You can get more support in the Gstreamer community.

Essentially, the problem was the wrong order of plugin and library paths. It loaded a plugin from a wrong location instead of from DeepStream.

These settings worked for me:

ENV DEBIAN_FRONTEND=noninteractive
NVIDIA_DRIVER_CAPABILITIES=${NVIDIA_DRIVER_CAPABILITIES},video
NVIDIA_VISIBLE_DEVICES=all
USE_NEW_NVSTREAMMUX=yes
GST_PLUGIN_PATH=/opt/nvidia/deepstream/deepstream-7.1/lib/gst-plugins:/opt/nvidia/deepstream/deepstream/lib/gst-plugins:/usr/lib/x86_64-linux-gnu/gstreamer-1.0/:/usr/lib/x86_64-linux-gnu/gstreamer1.0/
LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu:/opt/nvidia/deepstream/deepstream-7.1/lib:/opt/tritonserver/lib:/usr/lib/x86_64-linux-gnu:/usr/local/cuda/lib64:/opt/nvidia/deepstream/deepstream/lib:/usr/lib
PATH=“/usr/local/cuda/bin:${PATH}”
