🌐 What is RTMP Service?
RTMP, an acronym for Real-Time Messaging Protocol, is the most common and fundamental protocol for real-time streaming. It is applicable for both audio and video streaming and the exchange of data between a server and Flash player. Initially developed by Macromedia, now Adobe, RTMP remains the most commonly deployed protocol for live streaming.
Simply put,
- RTMP is a live streaming protocol that facilitates transmitting video files from an encoder to a streaming server
- AAC-LC is the best audio codec for RTMP streaming. However, AAC is also supported. H.264 is the best video codec for RTMP streaming. Most mp4 files are built using these codecs.
- OneStream uses RTMP to deliver a user’s content to the destination live streaming server.
- Broadcasters prefer RTMP streaming owing to its low latency. (HLS is another streaming protocol that is gaining popularity, but we leave that for another blog)

🔀 Benefits of RTMP Streaming
- Flexible – RTMP allows users to skip, rewind and forward the live stream or start watching it from anywhere they want. Users are not forced to watch the stream in one direction only or from one point only. RTMP can also be configured to use Adaptive bitrate streaming, although that requires the latest versions of flash player and some technical know-how.
- Low Latency – Capitalizing upon its ability to stream live content, whether audio or video, RTMP can stream with relatively low latency. This is a significant plus for broadcasters who regularly stream large-scale events in real-time.
- Minimal Buffering – RTMP is widely acknowledged for minimal buffering, which significantly enhances the user experience. Hence, RTMP also plays a lead role in some web conferencing tools.
- Secure Streaming – RTMPS, a secured version of RTMP, allows secure, encrypted transfer of streaming content from the encoder to the streaming destination. This prevents man-in-the-middle attacks or anyone eavesdropping on your feed.
- Reliable Live Streaming Experience – BY maintaining constant contact between the video player and the server, RTMP streaming allows an optimal streaming experience.
➡️ How Does RTMP Streaming Work?
RTMP was initially developed for high-performance transmission of data, both audio and video. Hence, RTMP maintains a continuous connection between the server and the player client, allowing the protocol to act as a transfer medium to transmit data to the viewer rapidly. Since RTMP sits on top of the Transmission Control Protocol (TCP), it uses a three-way handshake when transmitting data. The client (initiator) requests the server (accepter) to start a connection. The server responds, and the client acknowledges the response and maintains a session between either end.
