A Record is an arbitrary JSON data structure that can be created, retrieved, updated, deleted and listened to. 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. Its lightning-fast realtime data platform helps developers of any background or skillset build apps, IoT platforms, and backends that always stay in sync - without having to worry about infrastructure or .

Below diagram shows the smart record architecture: From DeepStream 6.0, Smart Record also supports audio. To start with, lets prepare a RTSP stream using DeepStream. 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. 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. Last updated on Oct 27, 2021. See the deepstream_source_bin.c for more details on using this module. How to find the performance bottleneck in DeepStream?
