Why do I observe a lot of buffers being dropped when running deepstream-nvdsanalytics-test application on Jetson Nano ? How to use the OSS version of the TensorRT plugins in DeepStream? You can design your own application functions. Records are the main building blocks of deepstream's data-sync capabilities. A Record is an arbitrary JSON data structure that can be created, retrieved, updated, deleted and listened to. Unable to start the composer in deepstream development docker. How to find out the maximum number of streams supported on given platform? because recording might be started while the same session is actively recording for another source. This is a good reference application to start learning the capabilities of DeepStream. 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 do I configure the pipeline to get NTP timestamps? In this documentation, we will go through, producing events to Kafka Cluster from AGX Xavier during DeepStream runtime, and. How can I display graphical output remotely over VNC? 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. By default, Smart_Record is the prefix in case this field is not set. Does Gst-nvinferserver support Triton multiple instance groups? This function starts writing the cached video data to a file.
