At the bottom are the different hardware engines that are utilized throughout the application. They will take video from a file, decode, batch and then do object detection and then finally render the boxes on the screen. Powered by Discourse, best viewed with JavaScript enabled. In existing deepstream-test5-app only RTSP sources are enabled for smart record. A video cache is maintained so that recorded video has frames both before and after the event is generated. Why is the Gst-nvstreammux plugin required in DeepStream 4.0+? Object tracking is performed using the Gst-nvtracker plugin. It will not conflict to any other functions in your application. 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. The following minimum json message from the server is expected to trigger the Start/Stop of smart record.
