Smart-rec-container=<0/1> 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. 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. It expects encoded frames which will be muxed and saved to the file. Why am I getting following warning when running deepstream app for first time? For unique names every source must be provided with a unique prefix. Sample Helm chart to deploy DeepStream application is available on NGC. On Jetson platform, I get same output when multiple Jpeg images are fed to nvv4l2decoder using multifilesrc plugin. How can I get more information on why the operation failed? Here, start time of recording is the number of seconds earlier to the current time to start the recording. When running live camera streams even for few or single stream, also output looks jittery? This function stops the previously started recording. How can I determine whether X11 is running? Configure Kafka server (kafka_2.13-2.8.0/config/server.properties): To host Kafka server, we open first terminal: Open a third terminal, and create a topic (You may think of a topic as a YouTube Channel which others people can subscribe to): You might check topic list of a Kafka server: Now, Kafka server is ready for AGX Xavier to produce events. That means smart record Start/Stop events are generated every 10 seconds through local events. DeepStream ships with several out of the box security protocols such as SASL/Plain authentication using username/password and 2-way TLS authentication. See the gst-nvdssr.h header file for more details. Can I stop it before that duration ends?

The params structure must be filled with initialization parameters required to create the instance. The registry failed to perform an operation and reported an error message. Can I record the video with bounding boxes and other information overlaid? Note that the formatted messages were sent to , lets rewrite our consumer.py to inspect the formatted messages from this topic. It returns the session id which later can be used in NvDsSRStop() to stop the corresponding recording. However, when configuring smart-record for multiple sources the duration of the videos are no longer consistent (different duration for each video). In existing deepstream-test5-app only RTSP sources are enabled for smart record. Gst-nvdewarper plugin can dewarp the image from a fisheye or 360 degree camera. # default duration of recording in seconds. This is a good reference application to start learning the capabilities of DeepStream. In the deepstream-test5-app, to demonstrate the use case smart record Start / Stop events are generated every interval second. In existing deepstream-test5-app only RTSP sources are enabled for smart record. Prefix of file name for generated video. After inference, the next step could involve tracking the object.

The DeepStream runtime system is pipelined to enable deep learning inference, image, and sensor processing, and sending insights to the cloud in a streaming application. Today, Deepstream has become the silent force behind some of the world's largest banks, communication, and entertainment companies. Gst-nvvideoconvert plugin can perform color format conversion on the frame. because recording might be started while the same session is actively recording for another source. 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 can I construct the DeepStream GStreamer pipeline? Building Intelligent Video Analytics Apps Using NVIDIA DeepStream 5.0 How do I obtain individual sources after batched inferencing/processing? In case duration is set to zero, recording will be stopped after defaultDuration seconds set in NvDsSRCreate(). Copyright 2020-2021, NVIDIA. Refer to this post for more details. It comes pre-built with an inference plugin to do object detection cascaded by inference plugins to do image classification. There are two ways in which smart record events can be generated either through local events or through cloud messages. How can I specify RTSP streaming of DeepStream output?
