Description

This presentation showcases pipelines with open sourced NVIDIA GStreamer plugins for GPU and NIC accelerated RTP transmit and receive (NvDsUdp) and NMOS integration (NvDsNmos) for uncompressed broadcast ST 2110 workflows with low CPU overhead and high throughput. It details technical advances such as direct GPU-to-NIC memory transfer, packet paced transmission, and kernel bypass for optimized networking, as well as dynamic endpoint registration and connection management via NMOS. Further, we introduce new SMPTE291 RTP payloader/depayloader for ancillary data streaming, which we demonstrate used in real-time AI enabled live workflows.
