The primary motivation for RTMP was to be a protocol for playing Flash video (Adobe Flash Player) maintaining persistent connections and allows low-latency communication, but in July 2017, Adobe announced that it would end support for Flash Player at the end of 2020, [1] and continued to encourage the use of open HTML5 standards in place of Flash.
Due to this RTMP streaming support is declining rapidly. But it is still very useful for broadcasting live, because of its low-latency. The Broadcaster ingest the stream through a RTMP server which then encodes and sends the resultant stream to a HLS [2] (HTTP Live Streaming) URL. Which then can use a number of players and devices from desktops to smartphones to social media sites.
Some full implementation RTMP servers are:
| Application | Platform | Description |
|---|---|---|
| Adobe Flash Player (web browser plug-in) | Windows, OS X, ChromeOS, Linux | The most widely adopted RTMP client, which supports playback of audio and video streamed from RTMP servers. |
| Gnash (web browser plug-in/media player) | Windows, Linux | An open source replacement for the Flash Player, intends to support RTMP streaming for Linux. [7] |
| VLC media player | Windows, OS X, Linux, iOS, Android | As of version 2.1+ Has partial support for playing RTMP streams (not RTMPE). |
| MPC-HC | Windows | As of version 1.7.8+ Can open rtmp streams if started from command prompt with the URL as argument, or with entering the URL into the "Open File..." dialog. |
| Kodi | Windows, OS X, Linux, iOS (jailbroken), Android | Has partial support for playing RTMP streams (not RTMPE). |
Flash Video is a container file format used to deliver digital video content over the Internet using Adobe Flash Player version 6 and newer. Flash Video content may also be embedded within SWF files. There are two different Flash Video file formats: FLV and F4V. The audio and video data within FLV files are encoded in the same way as SWF files. The F4V file format is based on the ISO base media file format, starting with Flash Player 9 update 3. Both formats are supported in Adobe Flash Player and developed by Adobe Systems. FLV was originally developed by Macromedia. In the early 2000s, Flash Video was the de facto standard for web-based streaming video. Users include Hulu, VEVO, Yahoo! Video, metacafe, Reuters.com, and many other news providers.
Real-Time Messaging Protocol (RTMP) is a communication protocol for streaming audio, video, and data over the Internet. Originally developed as a proprietary protocol by Macromedia for streaming between Flash Player and the Flash Communication Server, Adobe has released an incomplete version of the specification of the protocol for public use.
Adobe Media Server (AMS) is a proprietary data and media server from Adobe Systems. This server works with the Flash Player and HTML5 runtime to create media driven, multiuser RIAs. The server uses ActionScript 1, an ECMAScript based scripting language, for server-side logic. Prior to version 2, it was known as Flash Communication Server. Prior to version 5, it was known as Flash Media Server. In February 2019, Adobe Systems Incorporated granted Veriskope Inc rights to further develop, resell, and extend distribution of the software product.
Action Message Format (AMF) is a binary format used to serialize object graphs such as ActionScript objects and XML, or send messages between an Adobe Flash client and a remote service, usually a Flash Media Server or third party alternatives. The Actionscript 3 language provides classes for encoding and decoding from the AMF format.
Asao is a proprietary single-channel (mono) codec and compression format optimized for low-bitrate transmission of audio, developed by Nellymoser Inc.
The Secure Real-Time Media Flow Protocol (RTMFP) is a protocol suite developed by Adobe Systems for encrypted, efficient multimedia delivery through both client-server and peer-to-peer models over the Internet. The protocol was originally proprietary, but was later opened up and is now published as RFC 7016.
HTTP Live Streaming is an HTTP-based adaptive bitrate streaming communications protocol developed by Apple Inc. and released in 2009. Support for the protocol is widespread in media players, web browsers, mobile devices, and streaming media servers. As of 2019, an annual video industry survey has consistently found it to be the most popular streaming format.
Media Lovin' Toolkit (MLT) is an open source software multimedia framework, designed and developed for television broadcasting. It provides a toolkit for broadcasters, video editors, media players, transcoders, web streamers and many more types of applications. The functionality of the system is provided via an assortment of ready to use tools, XML authoring components, and an extensible plug-in based API.
Flash Media Live Encoder (FMLE) was a free live encoding software product from Adobe Systems. It was available for Microsoft Windows and Mac OS.
The Helix Universal Media Server was a product developed by RealNetworks and originates from the first streaming media server originally developed by Progressive Networks in 1994. It supported a variety of streaming media delivery transports including MPEG-DASH RTMP (flash), RTSP (standard), HTTP Live Streaming (HLS), Microsoft Silverlight and HTTP Progressive Download enabling mobile phone OS and PC OS media client delivery.
Sirannon is a free, open-source, media server and client. The goal is to aid in video research and experimental streaming. Sirannon allows the programmer to create a wide variety of media-handling components such as streaming, reading, writing, packetizing. By organizing these components in a workflow the programmer can create many applications such as a media server, media proxy or video tool. Sirannon was introduced at the ACM multimedia conference in October 2009 under its former name xStreamer.
Wowza Streaming Engine is a unified streaming media server software developed by Wowza. The server is used for streaming of live and on-demand video, audio, and rich Internet applications over IP networks to desktop, laptop, and tablet computers, mobile devices, IPTV set-top boxes, internet-connected TV sets, game consoles, and other network-connected devices. The server is a Java application deployable on most operating systems.
Intel Quick Sync Video is Intel's brand for its dedicated video encoding and decoding hardware core. Quick Sync was introduced with the Sandy Bridge CPU microarchitecture on 9 January 2011 and has been found on the die of Intel CPUs ever since.
Dynamic Adaptive Streaming over HTTP (DASH), also known as MPEG-DASH, is an adaptive bitrate streaming technique that enables high quality streaming of media content over the Internet delivered from conventional HTTP web servers. Similar to Apple's HTTP Live Streaming (HLS) solution, MPEG-DASH works by breaking the content into a sequence of small segments, which are served over HTTP. An early HTTP web server based streaming system called SProxy was developed and deployed in the Hewlett Packard Laboratories in 2006. It showed how to use HTTP range requests to break the content into small segments. SProxy shows the effectiveness of segment based streaming, gaining best Internet penetration due to the wide deployment of firewalls, and reducing the unnecessary traffic transmission if a user chooses to terminate the streaming session earlier before reaching the end. Each segment contains a short interval of playback time of content that is potentially many hours in duration, such as a movie or the live broadcast of a sport event. The content is made available at a variety of different bit rates, i.e., alternative segments encoded at different bit rates covering aligned short intervals of playback time. While the content is being played back by an MPEG-DASH client, the client uses a bit rate adaptation (ABR) algorithm to automatically select the segment with the highest bit rate possible that can be downloaded in time for playback without causing stalls or re-buffering events in the playback. The current MPEG-DASH reference client dash.js offers both buffer-based (BOLA) and hybrid (DYNAMIC) bit rate adaptation algorithms. Thus, an MPEG-DASH client can seamlessly adapt to changing network conditions and provide high quality playback with few stalls or re-buffering events.
Unreal Media Server is a streaming server software created by Unreal Streaming Technologies.
Red5 is a free software media streaming server implemented in Java, which provides services similar to those offered by the proprietary Adobe Flash Media Server and Wowza Streaming Engine including:
Media Source Extensions (MSE) is a W3C specification that allows JavaScript to send byte streams to media codecs within Web browsers that support HTML5 video and audio. Among other possible uses, this allows the implementation of client-side prefetching and buffering code for streaming media entirely in JavaScript. It is compatible with, but should not be confused with, the Encrypted Media Extensions (EME) specification, and neither requires the use of the other, although many EME implementations are only capable of decrypting media data provided via MSE.
