How do I configure the pipeline to get NTP timestamps? DeepStream applications can be deployed in containers using NVIDIA container Runtime. A video cache is maintained so that recorded video has frames both before and after the event is generated. In smart record, encoded frames are cached to save on CPU memory. After decoding, there is an optional image pre-processing step where the input image can be pre-processed before inference. Abubeker K.M, Assistant Professor Level 12, Electronics & Communication What are the recommended values for. At the bottom are the different hardware engines that are utilized throughout the application. There is an option to configure a tracker. How can I check GPU and memory utilization on a dGPU system?

What is the official DeepStream Docker image and where do I get it? . DeepStream is optimized for NVIDIA GPUs; the application can be deployed on an embedded edge device running Jetson platform or can be deployed on larger edge or datacenter GPUs like T4. By executing this consumer.py when AGX Xavier is producing the events, we now can read the events produced from AGX Xavier: Note that messages we received earlier is device-to-cloud messages produced from AGX Xavier. smart-rec-duration= What are the sample pipelines for nvstreamdemux? How to find out the maximum number of streams supported on given platform? Can I record the video with bounding boxes and other information overlaid? Surely it can. Why do I encounter such error while running Deepstream pipeline memory type configured and i/p buffer mismatch ip_surf 0 muxer 3? Custom broker adapters can be created. DeepStream builds on top of several NVIDIA libraries from the CUDA-X stack such as CUDA, TensorRT, NVIDIA Triton Inference server and multimedia libraries.
