Dacast Editorial Team \u2014 reviewed by Dacast\u2019s streaming infrastructure specialists. Updated : March 2026<\/strong><\/em><\/p>\n RTMP ingest is the process of sending a live video feed from an encoder to an online video platform (OVP). The encoder connects to the platform using an RTMP URL and stream key, transmitting continuous video data that the platform then repackages, typically into HLS<\/a>, for delivery to viewers on any device.<\/span><\/p>\n In 2026, live streaming<\/a> is the standard for everything from global sports broadcasts to internal company town halls. However, one of the most important technical decisions behind the scenes remains the choice of live streaming ingest protocol, the way your video gets from the encoder to the streaming platform.<\/span><\/p>\n While newer protocols like SRT and WebRTC are gaining traction for ultra-low-latency and peer-to-peer use cases, RTMP ingest<\/a> is still the backbone of most professional live streams. Its combination of reliability, encoder compatibility, and affordability has kept it as the default ingest method across the industry.<\/span><\/p>\n RTMP<\/a> ingest plays a central role for broadcasters using Dacast. It pushes streams into the platform, which then automatically delivers them to viewers via adaptive bitrate (ABR) HLS. This RTMP-to-HLS workflow ensures smooth playback on any device \u2014 from mobile to smart TVs \u2014 while giving broadcasters the flexibility to reach large audiences without technical headaches.<\/span><\/p>\n Table of Contents:<\/b><\/p>\n RTMP, or Real-Time Messaging Protocol, has been a cornerstone of online video for over two decades. Originally developed by Macromedia, later acquired by Adobe, it was designed to deliver audio and video through Flash Player, powering much of the early internet\u2019s video ecosystem, from embedded clips to early live streams. Back then, \u201cRTMP streaming\u201d and \u201cFlash streaming\u201d were practically synonymous.<\/span><\/p>\n By the early 2020s, browsers fully dropped Flash support, making RTMP-based delivery to players obsolete. But RTMP itself evolved. Today, its primary role is RTMP ingest: sending a live feed from an encoder into a streaming platform. From there, the video is repackaged into modern delivery formats like HLS for playback on any device.<\/p>\n Key distinction:<\/strong> RTMP delivery (Flash era) is dead. RTMP ingest, sending video into a platform, is very much alive and is the default ingest method across the streaming industry today.<\/span><\/p>\n When comparing RTMP vs. SRT<\/a> vs. WebRTC<\/a>, even as emerging protocols gain ground for specialized use cases, most broadcasters still rely on RTMP as the simplest, most proven ingest solution. That said, the protocol landscape is shifting, and hybrid workflows are becoming more common (more on that in the Future section).<\/span><\/p>\n RTMP ingest is the entry point for your live stream, the step where raw video captured by your camera first enters the professional streaming workflow. An encoder<\/a> (software like OBS Studio, or hardware like a Teradek device) connects to the platform using an RTMP URL and stream key, then continuously sends video data to the online video platform (OVP).<\/span><\/p>\n The basic path a live stream follows:<\/span><\/p>\n Camera \u2192 Encoder \u2192 Online Video Platform (RTMP) \u2192 CDN Servers \u2192 Video Player (HLS)<\/b><\/p>\n The OVP ingests the video, repackages it \u2014 usually into HLS with adaptive bitrate (ABR) \u2014 and distributes it through a content delivery network<\/a> (CDN) for smooth playback across devices.<\/span><\/p>\n Standard RTMP transmits data without encryption. Broadcasters today almost universally use RTMPS (RTMP over TLS\/SSL), which works identically but adds the same encryption layer that secures HTTPS websites. This protects the video feed from interception between the encoder and the platform.<\/p>\n RTMPS is especially important for:<\/span><\/p>\n Platforms like Dacast support RTMPS by default, and can layer in additional protections like tokenized URLs (time-limited stream keys), password protection, and domain-level access restrictions.<\/span><\/p>\n At a protocol level, every RTMP connection follows three phases:<\/span><\/p>\n For a deeper look into what RTMP is and why it\u2019s essential for live streaming, check out Dacast\u2019s Technical Series video: What Is RTMP?<\/strong> RTMP\u2019s most durable advantage is universal support across software and hardware encoders. Whether you\u2019re using free tools or professional-grade equipment, RTMP setup is consistent:<\/span><\/p>\n This means you can switch encoders or upgrade equipment without reconfiguring your platform integration.<\/span><\/p>\n RTMP ingest works from virtually any location without fixed IP addresses \u2014 streaming from conference halls, sports arenas, or outdoor venues without reconfiguring CDN channels.<\/span><\/p>\n SRT and WebRTC offer compelling features, but come with higher setup complexity and infrastructure costs. RTMP ingest remains a budget-friendly baseline:<\/span><\/p>\n RTMP ingest itself is not a delivery protocol. Paired with HLS<\/a> on a platform like Dacast, it supports low-latency delivery paths:<\/span><\/p>\n RTMP Ingest vs. RTMP Streaming (Delivery)<\/b><\/b><\/p>\n These two terms describe very different things, and the confusion causes real setup errors.<\/span><\/p>\n\n
