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. This function starts writing the cached audio/video data to a file. smart-rec-interval= DeepStream is only a SDK which provide HW accelerated APIs for video inferencing, video decoding, video processing, etc. What trackers are included in DeepStream and which one should I choose for my application?

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. mp4, mkv), DeepStream plugins failing to load without DISPLAY variable set when launching DS dockers, On Jetson, observing error : gstnvarguscamerasrc.cpp, execute:751 No cameras available. This recording happens in parallel to the inference pipeline running over the feed. In the deepstream-test5-app, to demonstrate the use case smart record Start / Stop events are generated every interval second. Can users set different model repos when running multiple Triton models in single process? Can I stop it before that duration ends? How to clean and restart? There is an option to configure a tracker. Only the data feed with events of importance is recorded instead of always saving the whole feed. This paper presents DeepStream, a novel data stream temporal clustering algorithm that dynamically detects sequential and overlapping clusters. My DeepStream performance is lower than expected. Does Gst-nvinferserver support Triton multiple instance groups? 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. 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.

It expects encoded frames which will be muxed and saved to the file. My component is getting registered as an abstract type. The deepstream-test3 shows how to add multiple video sources and then finally test4 will show how to IoT services using the message broker plugin. MP4 and MKV containers are supported. How can I know which extensions synchronized to registry cache correspond to a specific repository? Note that the formatted messages were sent to , lets rewrite our consumer.py to inspect the formatted messages from this topic. Do I need to add a callback function or something else? It comes pre-built with an inference plugin to do object detection cascaded by inference plugins to do image classification. If current time is t1, content from t1 - startTime to t1 + duration will be saved to file. Why do I see the below Error while processing H265 RTSP stream? In SafeFac a set of cameras installed on the assembly line are used to captu. Any data that is needed during callback function can be passed as userData. In case a Stop event is not generated. Why is a Gst-nvegltransform plugin required on a Jetson platform upstream from Gst-nveglglessink? For sending metadata to the cloud, DeepStream uses Gst-nvmsgconv and Gst-nvmsgbroker plugin. Why is the Gst-nvstreammux plugin required in DeepStream 4.0+?
