Can I record the video with bounding boxes and other information overlaid? 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. Freelancer What types of input streams does DeepStream 6.0 support? If you dont have any RTSP cameras, you may pull DeepStream demo container . You may use other devices (e.g. How to handle operations not supported by Triton Inference Server? In the deepstream-test5-app, to demonstrate the use case smart record Start / Stop events are generated every interval second. 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? How to extend this to work with multiple sources? Smart Video Record DeepStream 6.1.1 Release documentation, DeepStream Reference Application - deepstream-app DeepStream 6.1.1 Release documentation. The next step is to batch the frames for optimal inference performance. To enable smart record in deepstream-test5-app set the following under [sourceX] group: To enable smart record through only cloud messages, set smart-record=1 and configure [message-consumerX] group accordingly. DeepStream applications can be deployed in containers using NVIDIA container Runtime. This is a good reference application to start learning the capabilities of DeepStream. For creating visualization artifacts such as bounding boxes, segmentation masks, labels there is a visualization plugin called Gst-nvdsosd. There are several built-in broker protocols such as Kafka, MQTT, AMQP and Azure IoT. 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. Tensor data is the raw tensor output that comes out after inference. Optimizing nvstreammux config for low-latency vs Compute, 6. Does Gst-nvinferserver support Triton multiple instance groups? Where can I find the DeepStream sample applications? Abstract This work presents SafeFac, an intelligent camera-based system for managing the safety of factory environments. Recording also can be triggered by JSON messages received from the cloud. deepstream-test5 sample application will be used for demonstrating SVR. Whats the throughput of H.264 and H.265 decode on dGPU (Tesla)? The params structure must be filled with initialization parameters required to create the instance. Read more about DeepStream here. How to handle operations not supported by Triton Inference Server? Hardware Platform (Jetson / CPU) Once frames are batched, it is sent for inference. This means, the recording cannot be started until we have an Iframe. This function releases the resources previously allocated by NvDsSRCreate(). A Record is an arbitrary JSON data structure that can be created, retrieved, updated, deleted and listened to. The first frame in the cache may not be an Iframe, so, some frames from the cache are dropped to fulfil this condition. What are different Memory types supported on Jetson and dGPU? When deepstream-app is run in loop on Jetson AGX Xavier using while true; do deepstream-app -c ; done;, after a few iterations I see low FPS for certain iterations. 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. Smart Video Record DeepStream 6.1.1 Release documentation smart-rec-video-cache= Smart-rec-container=<0/1> Sample Helm chart to deploy DeepStream application is available on NGC. Smart video record is used for event (local or cloud) based recording of original data feed. How to find out the maximum number of streams supported on given platform? deepstream.io Record Records are one of deepstream's core features. Refer to this post for more details. What is the difference between DeepStream classification and Triton classification? For the output, users can select between rendering on screen, saving the output file, or streaming the video out over RTSP. How do I obtain individual sources after batched inferencing/processing? Why do I see the below Error while processing H265 RTSP stream? smart-rec-start-time= If current time is t1, content from t1 - startTime to t1 + duration will be saved to file. This function stops the previously started recording. The following minimum json message from the server is expected to trigger the Start/Stop of smart record. The SDK ships with several simple applications, where developers can learn about basic concepts of DeepStream, constructing a simple pipeline and then progressing to build more complex 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. Why am I getting following waring when running deepstream app for first time? What should I do if I want to set a self event to control the record? Does Gst-nvinferserver support Triton multiple instance groups? smart-rec-start-time= On Jetson platform, I observe lower FPS output when screen goes idle. What should I do if I want to set a self event to control the record? If you set smart-record=2, this will enable smart record through cloud messages as well as local events with default configurations. The pre-processing can be image dewarping or color space conversion. A video cache is maintained so that recorded video has frames both before and after the event is generated. because when I try deepstream-app with smart-recording configured for 1 source, the behaviour is perfect. Please see the Graph Composer Introduction for details. These plugins use GPU or VIC (vision image compositor). # default duration of recording in seconds. When executing a graph, the execution ends immediately with the warning No system specified. This function starts writing the cached video data to a file. Both audio and video will be recorded to the same containerized file. How can I determine the reason? Duration of recording. . Gst-nvdewarper plugin can dewarp the image from a fisheye or 360 degree camera. DeepStream is only a SDK which provide HW accelerated APIs for video inferencing, video decoding, video processing, etc. In existing deepstream-test5-app only RTSP sources are enabled for smart record. [When user expect to not use a Display window], My component is not visible in the composer even after registering the extension with registry. Please help to open a new topic if still an issue to support. When executing a graph, the execution ends immediately with the warning No system specified. For example, the record starts when theres an object being detected in the visual field. 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. What trackers are included in DeepStream and which one should I choose for my application? Note that the formatted messages were sent to , lets rewrite our consumer.py to inspect the formatted messages from this topic. In existing deepstream-test5-app only RTSP sources are enabled for smart record. Ive configured smart-record=2 as the document said, using local event to start or end video-recording. 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. 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 There are several built-in reference trackers in the SDK, ranging from high performance to high accuracy. Can Jetson platform support the same features as dGPU for Triton plugin? This function creates the instance of smart record and returns the pointer to an allocated NvDsSRContext. How can I display graphical output remotely over VNC? Why do I observe: A lot of buffers are being dropped. GstBin which is the recordbin of NvDsSRContext must be added to the pipeline. It returns the session id which later can be used in NvDsSRStop() to stop the corresponding recording. Smart-rec-container=<0/1> How to tune GPU memory for Tensorflow models? There are deepstream-app sample codes to show how to implement smart recording with multiple streams. #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), DeepStream Triton Inference Server Usage Guidelines, DeepStream Reference Application - deepstream-app, Expected Output for the DeepStream Reference Application (deepstream-app), DeepStream Reference Application - deepstream-test5 app, IoT Protocols supported and cloud configuration, DeepStream Reference Application - deepstream-audio app, ONNX Parser replace instructions (x86 only), DeepStream Reference Application on GitHub, Implementing a Custom GStreamer Plugin with OpenCV Integration Example, Description of the Sample Plugin: gst-dsexample, Enabling and configuring the sample plugin, Using the sample plugin in a custom application/pipeline, Implementing Custom Logic Within the Sample Plugin, Custom YOLO Model in the DeepStream YOLO App, IModelParser Interface for Custom Model Parsing, Configure TLS options in Kafka config file for DeepStream, Choosing Between 2-way TLS and SASL/Plain, Application Migration to DeepStream 5.0 from DeepStream 4.X, Major Application Differences with DeepStream 4.X, Running DeepStream 4.x compiled Apps in DeepStream 5.0, Compiling DeepStream 4.X Apps in DeepStream 5.0, User/Custom Metadata Addition inside NvDsBatchMeta, Adding Custom Meta in Gst Plugins Upstream from Gst-nvstreammux, Adding metadata to the plugin before Gst-nvstreammux, Gst-nvinfer File Configuration Specifications, To read or parse inference raw tensor data of output layers, Gst-nvinferserver File Configuration Specifications, Low-Level Tracker Library Comparisons and Tradeoffs, nvds_msgapi_connect(): Create a Connection, nvds_msgapi_send() and nvds_msgapi_send_async(): Send an event, nvds_msgapi_subscribe(): Consume data by subscribing to topics, nvds_msgapi_do_work(): Incremental Execution of Adapter Logic, nvds_msgapi_disconnect(): Terminate a Connection, nvds_msgapi_getversion(): Get Version Number, nvds_msgapi_get_protocol_name(): Get name of the protocol, nvds_msgapi_connection_signature(): Get Connection signature, Connection Details for the Device Client Adapter, Connection Details for the Module Client Adapter, nv_msgbroker_connect(): Create a Connection, nv_msgbroker_send_async(): Send an event asynchronously, nv_msgbroker_subscribe(): Consume data by subscribing to topics, nv_msgbroker_disconnect(): Terminate a Connection, nv_msgbroker_version(): Get Version Number, You are migrating from DeepStream 4.0+ to DeepStream 5.0, NvDsBatchMeta not found for input buffer error while running DeepStream pipeline, The DeepStream reference application fails to launch, or any plugin fails to load, Application fails to run when the neural network is changed, The DeepStream application is running slowly (Jetson only), The DeepStream application is running slowly, NVIDIA Jetson Nano, deepstream-segmentation-test starts as expected, but crashes after a few minutes rebooting the system, Errors occur when deepstream-app is run with a number of streams greater than 100, Errors occur when deepstream-app fails to load plugin Gst-nvinferserver on dGPU only, Tensorflow models are running into OOM (Out-Of-Memory) problem, Memory usage keeps on increasing when the source is a long duration containerized files(e.g. Why am I getting following waring when running deepstream app for first time? They will take video from a file, decode, batch and then do object detection and then finally render the boxes on the screen. Recording also can be triggered by JSON messages received from the cloud. My DeepStream performance is lower than expected. To enable audio, a GStreamer element producing encoded audio bitstream must be linked to the asink pad of the smart record bin. '/usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgstlibav.so': # Configure this group to enable cloud message consumer.
