During container builder installing graphs, sometimes there are unexpected errors happening while downloading manifests or extensions from registry. Configure Kafka server (kafka_2.13-2.8.0/config/server.properties): To host Kafka server, we open first terminal: Open a third terminal, and create a topic (You may think of a topic as a YouTube Channel which others people can subscribe to): You might check topic list of a Kafka server: Now, Kafka server is ready for AGX Xavier to produce events. What are different Memory types supported on Jetson and dGPU? Batching is done using the Gst-nvstreammux plugin. Does Gst-nvinferserver support Triton multiple instance groups? Why do I see tracker_confidence value as -0.1.? The property bufapi-version is missing from nvv4l2decoder, what to do? What is the approximate memory utilization for 1080p streams on dGPU?

Can users set different model repos when running multiple Triton models in single process? Can users set different model repos when running multiple Triton models in single process? . In this documentation, we will go through, producing events to Kafka Cluster from AGX Xavier during DeepStream runtime, and. This is the time interval in seconds for SR start / stop events generation. Gst-nvdewarper plugin can dewarp the image from a fisheye or 360 degree camera. deepstream.io Any data that is needed during callback function can be passed as userData. When to start smart recording and when to stop smart recording depend on your design. How can I display graphical output remotely over VNC? Can Gst-nvinferserver support inference on multiple GPUs? Are multiple parallel records on same source supported? Why am I getting following waring when running deepstream app for first time? Smart Parking Detection | NVIDIA NGC This application is covered in greater detail in the DeepStream Reference Application - deepstream-app chapter. To activate this functionality, populate and enable the following block in the application configuration file: While the application is running, use a Kafka broker to publish the above JSON messages on topics in the subscribe-topic-list to start and stop recording. Why do I see the below Error while processing H265 RTSP stream? userData received in that callback is the one which is passed during NvDsSRStart(). Records are the main building blocks of deepstream's data-sync capabilities. Can users set different model repos when running multiple Triton models in single process? Why do some caffemodels fail to build after upgrading to DeepStream 6.0? Are multiple parallel records on same source supported? deepstream-testsr is to show the usage of smart recording interfaces. On Jetson platform, I observe lower FPS output when screen goes idle. How to extend this to work with multiple sources? By default, the current directory is used. For unique names every source must be provided with a unique prefix. DeepStream applications can be orchestrated on the edge using Kubernetes on GPU. This function creates the instance of smart record and returns the pointer to an allocated NvDsSRContext. This means, the recording cannot be started until we have an Iframe. Recording also can be triggered by JSON messages received from the cloud. A Record is an arbitrary JSON data structure that can be created, retrieved, updated, deleted and listened to. The containers are available on NGC, NVIDIA GPU cloud registry. Only the data feed with events of importance is recorded instead of always saving the whole feed. Smart-rec-container=<0/1> Refer to this post for more details. A callback function can be setup to get the information of recorded video once recording stops. How can I check GPU and memory utilization on a dGPU system? Can I record the video with bounding boxes and other information overlaid? Can I record the video with bounding boxes and other information overlaid? This parameter will increase the overall memory usages of the application. There are more than 20 plugins that are hardware accelerated for various tasks. Following are the default values of configuration parameters: Following fields can be used under [sourceX] groups to configure these parameters. Can I record the video with bounding boxes and other information overlaid? There are two ways in which smart record events can be generated either through local events or through cloud messages. Smart Video Record DeepStream 6.1.1 Release documentation Can I stop it before that duration ends? # Use this option if message has sensor name as id instead of index (0,1,2 etc.).

The property bufapi-version is missing from nvv4l2decoder, what to do? How to clean and restart? How can I interpret frames per second (FPS) display information on console? DeepStream pipelines can be constructed using Gst-Python, the GStreamer frameworks Python bindings. The message format is as follows: Receiving and processing such messages from the cloud is demonstrated in the deepstream-test5 sample application. My DeepStream performance is lower than expected. Also included are the source code for these applications. deepstream smart record. In existing deepstream-test5-app only RTSP sources are enabled for smart record. Why I cannot run WebSocket Streaming with Composer? You may also refer to Kafka Quickstart guide to get familiar with Kafka. What is maximum duration of data I can cache as history for smart record? By default, Smart_Record is the prefix in case this field is not set. Can I stop it before that duration ends? Any data that is needed during callback function can be passed as userData. Any change to a record is instantly synced across all connected clients. Where can I find the DeepStream sample applications? Based on the event, these cached frames are encapsulated under the chosen container to generate the recorded video. This module provides the following APIs.

TensorRT accelerates the AI inference on NVIDIA GPU. because when I try deepstream-app with smart-recording configured for 1 source, the behaviour is perfect. Modifications made: (1) based on the results of the real-time video analysis, and: (2) by the application user through external input. Duration of recording. The core SDK consists of several hardware accelerator plugins that use accelerators such as VIC, GPU, DLA, NVDEC and NVENC. DeepStream is an optimized graph architecture built using the open source GStreamer framework. Why do some caffemodels fail to build after upgrading to DeepStream 5.1? I hope to wrap up a first version of ODE services and alpha v0.5 by the end of the week, Once released I'm going to start on the Deepstream 5 upgrade, and the Smart recording will be the first new ODE action to implement. smart-rec-video-cache= Why do I encounter such error while running Deepstream pipeline memory type configured and i/p buffer mismatch ip_surf 0 muxer 3? Ive already run the program with multi streams input while theres another question Id like to ask. What trackers are included in DeepStream and which one should I choose for my application?

The latest release of #NVIDIADeepStream SDK version 6.2 delivers powerful enhancements such as state-of-the-art multi-object trackers, support for lidar and How to tune GPU memory for Tensorflow models? See the gst-nvdssr.h header file for more details. Finally to output the results, DeepStream presents various options: render the output with the bounding boxes on the screen, save the output to the local disk, stream out over RTSP or just send the metadata to the cloud. There are deepstream-app sample codes to show how to implement smart recording with multiple streams. Yes, on both accounts.
