Which streaming formats are you currently using for ingest?Ĭontent distributors aren’t limited to one streaming RTMP encoders are still a go-to for many content producers, and a whopping 76.6% of respondents to our 2021 Video Streaming Latency Report currently use it for ingest. So, Is RTMP Dead?įlash’s end-of-life date was overdue. In Adobe’s own words, content distributors are encouraged “to migrate any existing Flash content to… new open formats.”Ĭheck out our blog on The History of Streaming Media for a more detailed look. With this move, adaptive bitrate streaming has become more common, allowing broadcasters to optimize content for viewers’ devices and connectivity.įewer devices support Flash (and by extension RTMP) than ever before. Using these technologies improves scalability and viewing experience by allowing local servers to cache streaming content. The industry now favors HTTP-based (Hypertext Transfer Protocol) protocols that use plain-old web servers. The writing on the wall came when Adobe announced the death of Flash - which occurred on December of 2020. And as a stateful protocol, RTMP also requires a dedicated streaming server, making it resource-heavy. Why? Although RTMP works well, it historically encountered issues getting past firewalls. But HTML5 video streaming, open standards, and adaptive bitrate delivery eventually edged RTMP streaming out when it came to last-mile delivery. When used together, these technologies support lightning-fast video delivery with around five seconds of latency. For this reason, RTMP is quite reliable.įlash Player and RTMP were the dominant delivery mechanisms for live streaming up until the early 2010s. The initiator (client) asks the accepter (server) to start a connection the accepter responds then the initiator acknowledges the response and maintains a session between either end. RTMP maintains a constant connection between the player client and server, allowing the protocol to act as a pipe and rapidly move video data through to the viewer.īecause RTMP sits on top of the Transmission Control Protocol (TCP), it uses a three-way handshake when transporting data. Macromedia (which is today Adobe Systems) developed the RTMP specification for high-performance transmission of audio and video data. Variant Formats: RTMPT (tunneled through HTTP), RTMPE (encrypted), RTMPTE (tunneled and encrypted), RTMPS (encrypted over SSL), RTMFP (layered over UDP instead of TCP).Drawbacks: No longer being updated or supported.

“Adobe’s Real Time Messaging Protocol (RTMP) provides a bidirectional message multiplex service over a reliable stream transport, such as TCP, intended to carry parallel streams of video, audio, and data messages, with associated timing information, between a pair of communicating peers.” RTMP Streaming: A Snapshot While once proprietary, RTMP is now an open specification. The RTMP specification is a streaming protocol initially designed for the transmission of audio, video, and other data between a dedicated streaming server and the Adobe Flash Player.
WOWZA RTMP SERVER HOW TO
In this article, we’ll look at the RTMP specification, the history behind RTMP streaming, how to start streaming with an RTMP encoder, and alternative protocols to consider. However, RTMP streams run into compatibility issues when it comes to playback on popular browsers and devices. Even big social media players like Facebook, YouTube, and Twitch accept it. The majority of encoders today can transmit RTMP, and most media servers can receive it. Because this popular Flash plugin powered 98% of internet browsers in its heyday, RTMP was used ubiquitously. The protocol started out as the secret sauce behind live and on-demand streaming with Adobe Flash Player. RTMP is a TCP-based protocol designed to maintain persistent, low-latency connections - and by extension, smooth streaming experiences. In the early days of streaming, the Real-Time Messaging Protocol (RTMP) was the de facto standard for transporting video over the internet (or in laymen’s terms, streaming).
