This button displays the currently selected search type. Running with an X server by creating virtual display, 2 . What are the sample pipelines for nvstreamdemux? The pre-processing can be image dewarping or color space conversion. That means smart record Start/Stop events are generated every 10 seconds through local events. 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. Freelancer Records are created and retrieved using client.record.getRecord ('name') To learn more about how they are used, have a look at the Record Tutorial.
