Why is the Gst-nvstreammux plugin required in DeepStream 4.0+? How does secondary GIE crop and resize objects? The first frame in the cache may not be an Iframe, so, some frames from the cache are dropped to fulfil this condition. 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. do you need to pass different session ids when recording from different sources? Records are created and retrieved using client.record.getRecord ('name') To learn more about how they are used, have a look at the Record Tutorial. Native TensorRT inference is performed using Gst-nvinfer plugin and inference using Triton is done using Gst-nvinferserver plugin. DeepStream provides building blocks in the form of GStreamer plugins that can be used to construct an efficient video analytic pipeline. When to start smart recording and when to stop smart recording depend on your design. 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. When executing a graph, the execution ends immediately with the warning No system specified. What is the GPU requirement for running the Composer?
