DeepStream 5.1 In existing deepstream-test5-app only RTSP sources are enabled for smart record. Smart video recording (SVR) is an event-based recording that a portion of video is recorded in parallel to DeepStream pipeline based on objects of interests or specific rules for recording. NVIDIA introduced Python bindings to help you build high-performance AI applications using Python. The events are transmitted over Kafka to a streaming and batch analytics backbone. DeepStream is an optimized graph architecture built using the open source GStreamer framework. It returns the session id which later can be used in NvDsSRStop() to stop the corresponding recording. They are atomic bits of JSON data that can be manipulated and observed. There are deepstream-app sample codes to show how to implement smart recording with multiple streams.

What are different Memory transformations supported on Jetson and dGPU? London, awarded World book of records Here, start time of recording is the number of seconds earlier to the current time to start the recording. This function releases the resources previously allocated by NvDsSRCreate(). For unique names every source must be provided with a unique prefix. Does Gst-nvinferserver support Triton multiple instance groups? How to handle operations not supported by Triton Inference Server? smart-rec-interval= # Use this option if message has sensor name as id instead of index (0,1,2 etc.). Optimizing nvstreammux config for low-latency vs Compute, 6. Based on the event, these cached frames are encapsulated under the chosen container to generate the recorded video. This causes the duration of the generated video to be less than the value specified. How do I obtain individual sources after batched inferencing/processing? Why do I observe: A lot of buffers are being dropped. It returns the session id which later can be used in NvDsSRStop() to stop the corresponding recording. Smart video record is used for event (local or cloud) based recording of original data feed. This paper presents DeepStream, a novel data stream temporal clustering algorithm that dynamically detects sequential and overlapping clusters.

Why is a Gst-nvegltransform plugin required on a Jetson platform upstream from Gst-nveglglessink? How to handle operations not supported by Triton Inference Server? Smart Video Record DeepStream 5.1 Release documentation 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. This is a good reference application to start learning the capabilities of DeepStream. Gst-nvdewarper plugin can dewarp the image from a fisheye or 360 degree camera. 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. In case a Stop event is not generated. For sending metadata to the cloud, DeepStream uses Gst-nvmsgconv and Gst-nvmsgbroker plugin. There are two ways in which smart record events can be generated - either through local events or through cloud messages. MP4 and MKV containers are supported. Why am I getting ImportError: No module named google.protobuf.internal when running convert_to_uff.py on Jetson AGX Xavier? DeepStream ships with several out of the box security protocols such as SASL/Plain authentication using username/password and 2-way TLS authentication.
