RUNTIME SOURCE ADDITION DELETION REFERENCE APP USING DEEPSTREAMSDK 4.0

Introduction

The project contains Runtime source addition/deletion application to show the capability of Deepstream SDK.

Prerequisites:

DeepStream SDK installed which is available at http://developer.nvidia.com/deepstream-sdk Please follow instructions in the apps/sample_apps/deepstream-app/README on how to install the prequisites for Deepstream SDK apps.

Getting Started

  • Export the environment variable: export DS_SDK_ROOT="your deepstream SDK root"

  • Preferably clone the app in $DS_SDK_ROOT/sources/apps/sample_apps/

  • Edit all the inference models config files according to the location of the models to be used

Compilation Steps and Execution

  $ make
  $ ./deepstream-test-rt-src-add-del <uri>
  $ ./deepstream-test-rt-src-add-del file://$DS_SDK_ROOT/samples/streams/sample_1080p_h265.mp4
  $ ./deepstream-test-rt-src-add-del rtsp://127.0.0.1/video

The application demonstrates following pipeline for single source

uridecodebin -> nvstreammux -> nvinfer -> nvtracker -> nvtiler -> nvvideoconvert -> nvdsosd -> displaysink

  • At runtime after a timeout a source will be added periodically. All the components are reconfigured during addition/deletion
  • After reaching of MAX_NUM_SOURCES, each source is deleted periodically till single source is present in the pipeline
  • The app exits, when final source End of Stream is reached or if the last source is deleted.
