These plugins use GPU or VIC (vision image compositor). What if I do not get expected 30 FPS from camera using v4l2src plugin in pipeline but instead get 15 FPS or less than 30 FPS? For unique names every source must be provided with a unique prefix. In case a Stop event is not generated. This means, the recording cannot be started until we have an Iframe. How can I specify RTSP streaming of DeepStream output? My DeepStream performance is lower than expected. To start with, lets prepare a RTSP stream using DeepStream. How can I get more information on why the operation failed? smart-rec-interval= If you set smart-record=2, this will enable smart record through cloud messages as well as local events with default configurations. In this documentation, we will go through Host Kafka server, producing events to Kafka Cluster from AGX Xavier during DeepStream runtime, and How can I interpret frames per second (FPS) display information on console? There are two ways in which smart record events can be generated - either through local events or through cloud messages. Do I need to add a callback function or something else? 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. The inference can use the GPU or DLA (Deep Learning accelerator) for Jetson AGX Xavier and Xavier NX. This is a good reference application to start learning the capabilities of DeepStream. There are several built-in broker protocols such as Kafka, MQTT, AMQP and Azure IoT. tensorflow python framework errors impl notfounderror no cpu devices are available in this process On Jetson platform, I get same output when multiple Jpeg images are fed to nvv4l2decoder using multifilesrc plugin. How do I configure the pipeline to get NTP timestamps? How can I determine the reason? To get started, developers can use the provided reference applications. 5.1 Adding GstMeta to buffers before nvstreammux. During container builder installing graphs, sometimes there are unexpected errors happening while downloading manifests or extensions from registry. The events are transmitted over Kafka to a streaming and batch analytics backbone. The following minimum json message from the server is expected to trigger the Start/Stop of smart record. My DeepStream performance is lower than expected. London, awarded World book of records Here, start time of recording is the number of seconds earlier to the current time to start the recording.
