How can I check GPU and memory utilization on a dGPU system? It takes the streaming data as input - from USB/CSI camera, video from file or streams over RTSP, and uses AI and computer vision to generate insights from pixels for better understanding of the environment. Why do I encounter such error while running Deepstream pipeline memory type configured and i/p buffer mismatch ip_surf 0 muxer 3? What happens if unsupported fields are added into each section of the YAML file? During container builder installing graphs, sometimes there are unexpected errors happening while downloading manifests or extensions from registry. Does smart record module work with local video streams? It uses same caching parameters and implementation as video. Below diagram shows the smart record architecture: From DeepStream 6.0, Smart Record also supports audio. There are several built-in broker protocols such as Kafka, MQTT, AMQP and Azure IoT. Do I need to add a callback function or something else? Prefix of file name for generated video. Records are the main building blocks of deepstream's data-sync capabilities. # Use this option if message has sensor name as id instead of index (0,1,2 etc.). Here, start time of recording is the number of seconds earlier to the current time to start the recording. Why is that? The plugin for decode is called Gst-nvvideo4linux2. A Record is an arbitrary JSON data structure that can be created, retrieved, updated, deleted and listened to. Why is that? See the deepstream_source_bin.c for more details on using this module. Add this bin after the parser element in the pipeline. How to find out the maximum number of streams supported on given platform? Using records Records are requested using client.record.getRecord (name). By performing all the compute heavy operations in a dedicated accelerator, DeepStream can achieve highest performance for video analytic applications. Video and Audio muxing; file sources of different fps, 3.2 Video and Audio muxing; RTMP/RTSP sources, 4.1 GstAggregator plugin -> filesink does not write data into the file, 4.2 nvstreammux WARNING Lot of buffers are being dropped, 5. The DeepStream Python application uses the Gst-Python API action to construct the pipeline and use probe functions to access data at various points in the pipeline. By default, Smart_Record is the prefix in case this field is not set. Edge AI device (AGX Xavier) is used for this demonstration. Why does the deepstream-nvof-test application show the error message Device Does NOT support Optical Flow Functionality ? What are different Memory types supported on Jetson and dGPU? Where can I find the DeepStream sample applications? What are the sample pipelines for nvstreamdemux? 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. In case a Stop event is not generated. Only the data feed with events of importance is recorded instead of always saving the whole feed. DeepStream pipelines can be constructed using Gst-Python, the GStreamer frameworks Python bindings. How to enable TensorRT optimization for Tensorflow and ONNX models? What if I dont set video cache size for smart record? Issue Type( questions). Why am I getting ImportError: No module named google.protobuf.internal when running convert_to_uff.py on Jetson AGX Xavier? 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. NVIDIA introduced Python bindings to help you build high-performance AI applications using Python. The params structure must be filled with initialization parameters required to create the instance. 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? There are two ways in which smart record events can be generated - either through local events or through cloud messages. How to clean and restart? In existing deepstream-test5-app only RTSP sources are enabled for smart record. Read more about DeepStream here. How do I configure the pipeline to get NTP timestamps? Configure [source0] and [sink1] groups of DeepStream app config configs/test5_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt so that DeepStream is able to use RTSP source from step 1 and render events to your Kafka server: At this stage, our DeepStream application is ready to run and produce events containing bounding box coordinates to Kafka server: To consume the events, we write consumer.py. To enable smart record in deepstream-test5-app set the following under [sourceX] group: smart-record=<1/2> This means, the recording cannot be started until we have an Iframe. This is a good reference application to start learning the capabilities of DeepStream. How can I run the DeepStream sample application in debug mode? How to extend this to work with multiple sources? . What is the difference between batch-size of nvstreammux and nvinfer? Can I stop it before that duration ends? What are different Memory transformations supported on Jetson and dGPU? 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. See the gst-nvdssr.h header file for more details. Ive configured smart-record=2 as the document said, using local event to start or end video-recording. What is the difference between batch-size of nvstreammux and nvinfer? To read more about these apps and other sample apps in DeepStream, see the C/C++ Sample Apps Source Details and Python Sample Apps and Bindings Source Details. Uncategorized. If you are trying to detect an object, this tensor data needs to be post-processed by a parsing and clustering algorithm to create bounding boxes around the detected object. #sensor-list-file=dstest5_msgconv_sample_config.txt, Install librdkafka (to enable Kafka protocol adaptor for message broker), Run deepstream-app (the reference application), Remove all previous DeepStream installations, Run the deepstream-app (the reference application), dGPU Setup for RedHat Enterprise Linux (RHEL), How to visualize the output if the display is not attached to the system, 1 . What should I do if I want to set a self event to control the record? Yes, on both accounts. The params structure must be filled with initialization parameters required to create the instance. In case duration is set to zero, recording will be stopped after defaultDuration seconds set in NvDsSRCreate(). How can I change the location of the registry logs? What if I do not get expected 30 FPS from camera using v4l2src plugin in pipeline but instead get 15 FPS or less than 30 FPS? It expects encoded frames which will be muxed and saved to the file. They are atomic bits of JSON data that can be manipulated and observed. What is maximum duration of data I can cache as history for smart record? Size of video cache in seconds. See NVIDIA-AI-IOT Github page for some sample DeepStream reference apps. Why do I see the below Error while processing H265 RTSP stream? It returns the session id which later can be used in NvDsSRStop() to stop the corresponding recording. # Configure this group to enable cloud message consumer. Why is a Gst-nvegltransform plugin required on a Jetson platform upstream from Gst-nveglglessink? For unique names every source must be provided with a unique prefix. Native TensorRT inference is performed using Gst-nvinfer plugin and inference using Triton is done using Gst-nvinferserver plugin. How can I display graphical output remotely over VNC?
