An open-source protocol called Real-Time Messaging Protocol (RTMP), which Adobe owns is made for streaming audio and video while preserving low-latency connections. The RTMP protocol broadcasts data, audio, and video across the internet. A server that uses the RTMP protocol to control the streaming of audio and video content from a source to one or more clients is known as an RTMP server.

A video encoder or camera may be the source of the data an RTMP server receives and transmits to one or more connected clients. Web browsers, mobile devices, or other programs receiving RTMP streams can be the clients.

Live video streaming frequently employs RTMP servers, particularly for occasions like sporting events, concerts, and conferences. They are also utilized for video-on-demand (VOD) services, where users can access previously recorded videos as needed.

Adobe Media Server, Wowza Streaming Engine, and Red5 are well-known RTMP servers.


Using an RTMP server for video-on-demand and live-streaming services has various benefits:

1. Low latency: Low latency allows your live video stream to maintain a stable connection and video feed for the viewer, even if the internet connection is unreliable. This gives your viewers fewer “lags” when watching your videos with a shaky internet connection, allowing them to quickly resume the stream once their internet connection stabilizes. RTMP allows for a better viewing experience.

2. High-quality streaming: High-quality streaming with little demand on bandwidth is made possible by RTMP servers’ use of cutting-edge codecs like H.264 for video and AAC for music. By doing this, customers can enjoy pixelated or buffering-free high-quality video and audio.

3. Adaptive bitrate streaming: With adaptive bitrate streaming, the video quality can be automatically adjusted by RTMP servers based on the user’s internet connection speed. Customers can stream uninterrupted, even with a slow internet connection.

4. Scalability: RTMP servers may easily scale up or down to support multiple concurrent users, depending on the demand for streaming services.


The control of audio and video content streaming from a source to one or more clients is the responsibility of an RTMP server. Here is how an RTMP server functions:

  1. A stream of audio and video data is sent to the RTMP server by a video source, such as a camera or a video encoder. Both the H.264 video and AAC audio codecs are used in the encoding of this stream.
  1. The RTMP server receives the data stream and is kept in a buffer. The data is then divided into smaller portions and sent to the clients by the server.
  1. The clients request the audio and video stream by connecting to the RTMP server. Clients can be other apps, mobile devices, or web browsers. The server sends the split data online to the clients.
  1. After receiving the segmented data, the clients decode it with the H.264 video and AAC audio codecs. The user is then given a real-time playback of the audio and video.

Large amounts of streaming data can be handled using RTMP servers, which offer dependable and steady streaming. They employ sophisticated algorithms to maintain audio and video quality and optimize internet data delivery throughout the streaming process.

In general, an RTMP server is a crucial part of any live streaming or video-on-demand service since it enables the effective delivery of audio and video material to users via the internet.
