In the deepstream-test5-app, to demonstrate the use case smart record Start / Stop events are generated every interval second. The increasing number of IoT devices in "smart" environments, such as homes, offices, and cities, produce seemingly endless data streams and drive many daily decisions. Any change to a record is instantly synced across all connected clients. Why does the deepstream-nvof-test application show the error message Device Does NOT support Optical Flow Functionality if run with NVIDIA Tesla P4 or NVIDIA Jetson Nano, Jetson TX2, or Jetson TX1? It returns the session id which later can be used in NvDsSRStop() to stop the corresponding recording. Issue Type( questions).

By executing this consumer.py when AGX Xavier is producing the events, we now can read the events produced from AGX Xavier: Note that messages we received earlier is device-to-cloud messages produced from AGX Xavier. This causes the duration of the generated video to be less than the value specified. When executing a graph, the execution ends immediately with the warning No system specified. DeepStream is a streaming analytic toolkit to build AI-powered applications. How can I display graphical output remotely over VNC? How to extend this to work with multiple sources? DeepStream abstracts these libraries in DeepStream plugins, making it easy for developers to build video analytic pipelines without having to learn all the individual libraries. What is the approximate memory utilization for 1080p streams on dGPU? This causes the duration of the generated video to be less than the value specified. Before SVR is being triggered, configure [source0 ] and [message-consumer0] groups in DeepStream config (test5_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt): Once the app config file is ready, run DeepStream: Finally, you are able to see recorded videos in your [smart-rec-dir-path] under [source0] group of the app config file. This function stops the previously started recording. Smart video record is used for event (local or cloud) based recording of original data feed. That means smart record Start/Stop events are generated every 10 seconds through local events. Why is that? And once it happens, container builder may return errors again and again.
