AN RTMP encoder uses AMF to send the connection request to the server and indicate details like the connection URL, audio codec, and video codec. Connection: The client and server then negotiate a connection using Action Message Format (AMF) encoded messages.When the final (third) packet has been returned by the server, the handshake is complete. Having established two-way communication, the client sends one final packet, which is a copy of the timestamp.At this point, the server responds with echoes or copies of the two packets it’s just received, as well as a timestamp of when it received them. The second packet, which the client sends immediately without waiting for any response, includes a timestamp.The first packet sent by the client tells the server which version of RTMP is being streamed.

Handshake: The client, often taking the form of encoding software or hardware, initiates a connection with the server it wishes to stream to by exchanging three packets of data.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.Benefits: Low latency and minimal buffering.No longer accepted by iOS, Android, most browsers, and most embeddable players.Limited to Flash Player (which has been discontinued by Adobe), Adobe AIR, RTMP-compatible players.Playback Compatibility: Not widely supported.Video Codecs: H.264, VP8, VP6, Sorenson Spark ®, Screen Video v1 & v2.Audio Codecs: AAC, AAC-LC, HE-AAC+ v1 & v2, MP3, Speex.“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. Today, however, the protocol is most often used to deliver encoded content to social media platforms, streaming platforms, and media servers. RTMP was initially designed to transport audio and video data between a dedicated streaming server and the Adobe Flash Player. The Real-Time Messaging Protocol (RTMP) is a data transmission technology that supports live online video streaming.

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).
