This paper presents DeepStream, a novel data stream temporal clustering algorithm that dynamically detects sequential and overlapping clusters. What types of input streams does DeepStream 6.2 support? 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. How can I determine the reason? To enable smart record in deepstream-test5-app set the following under [sourceX] group: smart-record=<1/2> DeepStream is only a SDK which provide HW accelerated APIs for video inferencing, video decoding, video processing, etc. This function creates the instance of smart record and returns the pointer to an allocated NvDsSRContext. In this documentation, we will go through Host Kafka server, producing events to Kafka Cluster from AGX Xavier during DeepStream runtime, and What is the approximate memory utilization for 1080p streams on dGPU? How can I determine whether X11 is running? Why am I getting following waring when running deepstream app for first time? 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. Whats the throughput of H.264 and H.265 decode on dGPU (Tesla)? How to fix cannot allocate memory in static TLS block error? How to minimize FPS jitter with DS application while using RTSP Camera Streams? Are multiple parallel records on same source supported? Last updated on Oct 27, 2021. What is the recipe for creating my own Docker image? When running live camera streams even for few or single stream, also output looks jittery? How to find out the maximum number of streams supported on given platform? Are multiple parallel records on same source supported? How can I check GPU and memory utilization on a dGPU system? It will not conflict to any other functions in your application. How to tune GPU memory for Tensorflow models? Observing video and/or audio stutter (low framerate), 2. DeepStream SDK can be the foundation layer for a number of video analytic solutions like understanding traffic and pedestrians in smart city, health and safety monitoring in hospitals, self-checkout and analytics in retail, detecting component defects at a manufacturing facility and others. How to enable TensorRT optimization for Tensorflow and ONNX models? The inference can use the GPU or DLA (Deep Learning accelerator) for Jetson AGX Xavier and Xavier NX. By executing this trigger-svr.py when AGX is producing the events, we now can not only consume the messages from AGX Xavier but also produce JSON messages to in Kafka server which will be subscribed by AGX Xavier to trigger SVR. What are different Memory types supported on Jetson and dGPU? How to find out the maximum number of streams supported on given platform? Can users set different model repos when running multiple Triton models in single process? By default, Smart_Record is the prefix in case this field is not set. Revision 6f7835e1. If you set smart-record=2, this will enable smart record through cloud messages as well as local events with default configurations. There are several built-in reference trackers in the SDK, ranging from high performance to high accuracy. There are two ways in which smart record events can be generated either through local events or through cloud messages. The source code for this application is available in /opt/nvidia/deepstream/deepstream-6.0/sources/apps/sample_apps/deepstream-app. What is the difference between batch-size of nvstreammux and nvinfer? Duration of recording. mp4, mkv), Troubleshooting in NvDCF Parameter Tuning, Frequent tracking ID changes although no nearby objects, Frequent tracking ID switches to the nearby objects, Error while running ONNX / Explicit batch dimension networks, DeepStream plugins failing to load without DISPLAY variable set when launching DS dockers, 1. smart-rec-dir-path= In this app, developers will learn how to build a GStreamer pipeline using various DeepStream plugins. Sink plugin shall not move asynchronously to PAUSED, 5. Why do I observe: A lot of buffers are being dropped. The reference application has capability to accept input from various sources like camera, RTSP input, encoded file input, and additionally supports multi stream/source capability. On Jetson platform, I observe lower FPS output when screen goes idle. For sending metadata to the cloud, DeepStream uses Gst-nvmsgconv and Gst-nvmsgbroker plugin. In smart record, encoded frames are cached to save on CPU memory. mp4, mkv), Errors occur when deepstream-app is run with a number of RTSP streams and with NvDCF tracker, Troubleshooting in NvDCF Parameter Tuning, Frequent tracking ID changes although no nearby objects, Frequent tracking ID switches to the nearby objects. DeepStream supports application development in C/C++ and in Python through the Python bindings. In case duration is set to zero, recording will be stopped after defaultDuration seconds set in NvDsSRCreate(). In the deepstream-test5-app, to demonstrate the use case smart record Start / Stop events are generated every interval second. Which Triton version is supported in DeepStream 5.1 release? It uses same caching parameters and implementation as video. Adding a callback is a possible way. By default, the current directory is used. NVIDIA introduced Python bindings to help you build high-performance AI applications using Python. This app is fully configurable - it allows users to configure any type and number of sources. DeepStream ships with several out of the box security protocols such as SASL/Plain authentication using username/password and 2-way TLS authentication. How to tune GPU memory for Tensorflow models? Smart-rec-container=<0/1> How can I specify RTSP streaming of DeepStream output? See the deepstream_source_bin.c for more details on using this module. How can I specify RTSP streaming of DeepStream output? Why do I see the below Error while processing H265 RTSP stream? Can Gst-nvinferserver support models cross processes or containers? Here, start time of recording is the number of seconds earlier to the current time to start the recording. Prefix of file name for generated stream. By default, Smart_Record is the prefix in case this field is not set. The DeepStream runtime system is pipelined to enable deep learning inference, image, and sensor processing, and sending insights to the cloud in a streaming application. Once frames are batched, it is sent for inference. The property bufapi-version is missing from nvv4l2decoder, what to do? The DeepStream reference application is a GStreamer based solution and consists of set of GStreamer plugins encapsulating low-level APIs to form a complete graph. This function starts writing the cached video data to a file. Copyright 2021, Season. What is the difference between batch-size of nvstreammux and nvinfer? I'll be adding new github Issues for both items, but will leave this issue open until then. After pulling the container, you might open the notebook deepstream-rtsp-out.ipynb and create a RTSP source.
