Hardware Platform (Jetson / CPU) Observing video and/or audio stutter (low framerate), 2. The DeepStream 360d app can serve as the perception layer that accepts multiple streams of 360-degree video to generate metadata and parking-related events. Duration of recording. DeepStream is a streaming analytic toolkit to build AI-powered applications. smart-rec-cache= By performing all the compute heavy operations in a dedicated accelerator, DeepStream can achieve highest performance for video analytic applications. Why do some caffemodels fail to build after upgrading to DeepStream 6.0? For example, the record starts when theres an object being detected in the visual field. These 4 starter applications are available in both native C/C++ as well as in Python. The inference can be done using TensorRT, NVIDIAs inference accelerator runtime or can be done in the native framework such as TensorFlow or PyTorch using Triton inference server. In smart record, encoded frames are cached to save on CPU memory. The deepstream-test3 shows how to add multiple video sources and then finally test4 will show how to IoT services using the message broker plugin.

Users can also select the type of networks to run inference. Why does my image look distorted if I wrap my cudaMalloced memory into NvBufSurface and provide to NvBufSurfTransform? After decoding, there is an optional image pre-processing step where the input image can be pre-processed before inference. For sending metadata to the cloud, DeepStream uses Gst-nvmsgconv and Gst-nvmsgbroker plugin. This means, the recording cannot be started until we have an Iframe. Nothing to do, NvDsBatchMeta not found for input buffer error while running DeepStream pipeline, The DeepStream reference application fails to launch, or any plugin fails to load, Errors occur when deepstream-app is run with a number of streams greater than 100, After removing all the sources from the pipeline crash is seen if muxer and tiler are present in the pipeline, Some RGB video format pipelines worked before DeepStream 6.1 onwards on Jetson but dont work now, UYVP video format pipeline doesnt work on Jetson, Memory usage keeps on increasing when the source is a long duration containerized files(e.g. deepstream smart record. Finally to output the results, DeepStream presents various options: render the output with the bounding boxes on the screen, save the output to the local disk, stream out over RTSP or just send the metadata to the cloud. Records are the main building blocks of deepstream's data-sync capabilities. How can I check GPU and memory utilization on a dGPU system?

DeepStream is only a SDK which provide HW accelerated APIs for video inferencing, video decoding, video processing, etc. The inference can use the GPU or DLA (Deep Learning accelerator) for Jetson AGX Xavier and Xavier NX. Why do I encounter such error while running Deepstream pipeline memory type configured and i/p buffer mismatch ip_surf 0 muxer 3? Why do I see tracker_confidence value as -0.1.? A callback function can be setup to get the information of recorded video once recording stops. Here, start time of recording is the number of seconds earlier to the current time to start the recording. Please make sure you understand how to migrate your DeepStream 5.1 custom models to DeepStream 6.0 before you start. To activate this functionality, populate and enable the following block in the application configuration file: While the application is running, use a Kafka broker to publish the above JSON messages on topics in the subscribe-topic-list to start and stop recording. How to find out the maximum number of streams supported on given platform? The property bufapi-version is missing from nvv4l2decoder, what to do? Why is that? All the individual blocks are various plugins that are used. With DeepStream you can trial our platform for free for 14-days, no commitment required.
