Creating records Arvind Radhakrishnen auf LinkedIn: #bard #chatgpt #google #search # Last updated on Sep 10, 2021. There are two ways in which smart record events can be generated either through local events or through cloud messages. To enable audio, a GStreamer element producing encoded audio bitstream must be linked to the asink pad of the smart record bin. Here startTime specifies the seconds before the current time and duration specifies the seconds after the start of recording. When deepstream-app is run in loop on Jetson AGX Xavier using while true; do deepstream-app -c ; done;, after a few iterations I see low FPS for certain iterations. For example, if t0 is the current time and N is the start time in seconds that means recording will start from t0 N.

How to enable TensorRT optimization for Tensorflow and ONNX models? recordbin of NvDsSRContext is smart record bin which must be added to the pipeline. In smart record, encoded frames are cached to save on CPU memory. In case a Stop event is not generated. This is currently supported for Kafka. Smart video record is used for event (local or cloud) based recording of original data feed. Configure DeepStream application to produce events, 4. This function stops the previously started recording. After inference, the next step could involve tracking the object. If you set smart-record=2, this will enable smart record through cloud messages as well as local events with default configurations. 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. Below diagram shows the smart record architecture: This module provides the following APIs.
