Nagare Media Ingest: A Server for Live CMAF Ingest Workflows
Neugebauer, Matthias
Abstract
New media ingest protocols have been presented recently. SRT and RIST compete with old protocols such as RTMP while the DASH-IF specified an HTTP-based ingest protocol for CMAF formatted media that lends itself towards delivery protocols such as DASH and HLS. Additionally, use cases of media ingest workflows can vary widely. This makes implementing generic and flexible tools for ingest workflows a hard challenge. A monolithic approach limits adoption if the implementation does not fit the use case completely. We propose a new design for ingest servers that splits responsibilities into multiple components running concurrently. This design enables flexible ingest deployments as is discussed for various use cases. We have implemented this design in the open source software Nagare Media Ingest for the new DASH-IF ingest protocol.
