What is RTMP?

Real-Time Messaging Protocol (RTMP) is a communication technology that enables live video streaming over the internet. It’s based on Transmission Control Protocol (TCP) technology and was originally developed by Macromedia for their Flash Player, which later became Adobe Flash Player after the company was acquired by Adobe.

Originally, RTMP was mostly used to transmit content between a hosting server and a video player. Today, its purpose is a bit different. In terms of the most modern live streaming setups, RTMP’s primary role on streaming servers is to deliver content from an encoder to an online video host. This is a process known as “ingestion”.

In the context of its new role in live streaming, RTMP is important but also somewhat reduced in scope from what it used to do. It’s capable of low-latency streaming, which is a major plus for broadcasters who are streaming major events in real time. It’s also known for its minimal buffering, which truly enhances the user experience. RTMP streaming is one of the best ways to deliver low latency streaming no-buffer streaming content.

RTMP technology also plays a role in adaptive bitrate streaming and some web conferencing tools. There are several variations of the RTMP protocol used for several different purposes, which we’ll discuss further along in this post.

Key Facts About RTMP

To better understand RTMP and its role in live streaming, here are some essential facts about the protocol and how it works:

• RTMP is a live streaming protocol that efficiently transmits video and audio from an encoder to an online video hosting platform in real time.
• RTMP operates over TCP and UDP but does not stream over HTTP, unlike modern standards such as HLS.
• RTMP supports multiple audio codecs, including AAC and MP3, making it versatile for live and recorded streaming.
• H.264 (x264) is the most common video codec used with RTMP, but the protocol also supports other compression formats.
• RTMP ingest is widely supported by low-cost and professional encoding tools, making it an accessible option for broadcasters.
• On platforms like Dacast, RTMP ingest automatically converts to HLS, ensuring compatibility with iOS, Android, and web browsers.
• RTMP has several variations, including RTMPS (secure streaming), though its use has declined.
• Adobe discontinued official support for RTMP, and it is no longer natively supported in web browsers due to the deprecation of Flash.

Is RTMP Still in Use?

While RTMP is no longer a go-to protocol for video playback, it remains a crucial part of many live streaming workflows. Broadcasters continue to use RTMP for ingesting streams into media servers, where it is transcoded and delivered via HLS or other modern streaming formats.

The Three Primary Components of RTMP

RTMP operates based on three primary components, each serving a specific purpose in the live-streaming workflow:

1. RTMP Server: The RTMP server acts as the central hub for handling incoming streams and distributing them to connected clients. It manages the media data flow, handles authentication, and ensures smooth transmission between the server and clients.
2. RTMP Client: The RTMP client is responsible for receiving the live video and audio streams from the server and presenting them to the end viewer. Clients can range from web browsers and mobile applications to dedicated streaming software.
3. RTMP Protocol: The RTMP protocol defines the rules and mechanisms for the delivery of media content over the network. It enables real-time communication, supports adaptive bitrate streaming, and facilitates the exchange of control messages between the server and client.

The Advantages of RTMP

RTMP offers several key advantages that have contributed to its widespread adoption in the live-streaming industry:

1. Low Latency: RTMP minimizes the delay between the time the content is captured and when it reaches the viewer’s screen. This low latency is crucial for live events, where real-time interaction and engagement are paramount.
2. Adaptive Bitrate Streaming: With RTMP, broadcasters can deliver live streams at different quality levels, adapting to the viewer’s internet connection and device capabilities. This ensures a seamless viewing experience, regardless of varying network conditions.
3. Wide Platform Compatibility: RTMP is supported by a wide range of platforms, including desktops, mobile devices, smart TVs, and set-top boxes. This compatibility allows broadcasters to reach a larger audience across multiple devices and operating systems.
4. Interactive Features: RTMP supports interactivity by enabling features such as live chat, real-time audience polling, and synchronized playback. These interactive elements enhance viewer engagement and foster a sense of community during live streams.

RTMP in Action: The Live Streaming Workflow

To fully grasp the significance of RTMP in the live streaming ecosystem, let’s walk through a typical live streaming workflow that incorporates RTMP technology:

1. Capture and Encoding: The live video and audio content are captured using cameras, microphones, or professional broadcasting equipment. These signals are then encoded into a digital format suitable for transmission.
2. RTMP Server Configuration: The broadcaster configures an RTMP server, specifying the necessary settings such as stream keys, access control, and streaming quality parameters.
3. Streaming Software Setup: Broadcasting software, such as OBS (Open Broadcaster Software) or Wirecast, is configured to establish a connection with the RTMP server. The software handles the encoding, packaging, and transmission of the live content.
4. Initiating the Live Stream: With the streaming software configured, the broadcaster initiates the live stream, which establishes a connection with the RTMP server. The server receives the encoded data and prepares it for distribution.
5. Viewer Engagement: Viewers access the live stream through various platforms, including websites, social media platforms, or dedicated streaming applications. The RTMP client on their end receives the video and audio streams from the server, allowing them to watch the live content in real time.
6. Real-Time Interactivity: During the live stream, viewers can actively engage with the content and other participants through features such as chat, comments, likes, and interactive overlays. These interactive elements foster a dynamic and immersive viewing experience.
7. Archiving and Storage: After the live stream concludes, broadcasters often have the option to archive the recorded stream for later playback. This feature enables on-demand access to previously streamed content, extending its reach beyond the live event.

RTMP Metrics to Monitor

Bitrate

Monitoring bitrate helps you understand the quality of your RTMP video stream. If the bitrate fluctuates too much or drops too low, viewers may experience buffering or poor video quality. A steady bitrate shows that your connection and encoder settings are working well.

Dropped frames

Dropped frames happen when your system or network can’t keep up with the stream. It’s a key sign that something may be off in your RTMP setup. Too many dropped frames can make your RTMP feed look choppy or unstable.

Ingest health

Ingest health shows how well your RTMP stream is being received by the server. This metric tells you if your RTMP live stream is reliable or needs adjustment.

RTMP in Hybrid Workflows

In today’s streaming setups, RTMP still plays a vital role—especially in hybrid workflows. While it’s no longer used for playback, it remains a reliable ingest option. A typical RTMP live streaming workflow starts with an RTMP encoder, such as OBS or Wirecast, sending a feed from an RTMP camera or RTMP source. The RTMP stream is then delivered to a media server, like Dacast, which repackages the content into HLS, DASH, or WebRTC for final delivery. This setup allows for smooth RTMP broadcasting while keeping the delivery protocol modern and secure.

This approach uses the strengths of the RTMP protocol—low-latency input and broad encoder support—while overcoming its limits with newer delivery tech. Below is a diagram showing this hybrid RTMP workflow:

Encoder → RTMP → Dacast Server → HLS/WebRTC to Viewers

Why RTMP Ingest is Still Relevant

1. Fast, stable transmission – RTMP provides low-latency and reliable delivery of video streams from encoders to media servers.
2. Broad industry support – Most streaming platforms, including Dacast, YouTube Live, and Facebook Live, still support RTMP ingest.
3. Seamless integration with HLS – RTMP streams are often ingested by media servers and converted to HLS for final playback on viewers’ devices.
4. Works with affordable encoding tools – Many low-cost and professional encoders continue to support RTMP ingest, making it accessible for broadcasters.

Should You Use RTMP in 2025?

RTMP has been around for years, but is it still the right choice for your live streaming needs in 2025? Here’s a simple way to decide.

Yes: You need low-cost ingest and widespread encoder compatibility.
If you want an easy way to get your stream online, RTMP is still a great option. It works with nearly every live video encoder and app. You can connect your camera to an RTMP-supported platform like Dacast and stream quickly without complex setup. RTMP’s meaning in today’s workflows is clear—it’s reliable, affordable, and widely supported.

No: You require ultra-low latency for auctions, real-time chat, or game streaming.
If your use case depends on real-time interactions, RTMP may not be fast enough. In these cases, consider alternatives like SRT or WebRTC, which are built for near-instant delivery. RTMP is still powerful, but its limits show in ultra-low-latency needs.

How Does RTMP Ingest Work?

Three distinct components make RTMP ingest work:

1. The handshake
2. The connection
3. The stream

This sequence of events can happen almost instantaneously. RTMP ingestion is a relatively simple process, but it’s complicated by the fact that the protocol is no longer supported by Adobe.

RTMP ingestion mostly takes place in professional broadcast environments these days. It can get complicated, but one of the reasons it sticks around is that it has long been a reliable and manageable tool for streaming video. It can still integrate easily with a professional video hosting platform.

Here’s a quick breakdown of the RTMP ingest process.

Step 1: The Handshake

The handshake phase involves a series of quick exchanges between the client and server. First, the client sends what’s commonly called a header. This is a cryptographic signature. Immediately after the header is sent, the client sends 1536 bytes of random data.

The server then responds in kind: it sends a header, then 1536 bytes of random data immediately following it. Finally, the client sends the server a copy of the server’s random data back to them, then the server sends the client a copy of the client’s random data back to them. This completes the handshake.

Step 2: The Connection

Once the handshake is complete, the connection phase is in effect. The connection phase involves an exchange of data using AMF (Action Message Format) encoding. This establishes a communication standard between the client and server, including general specifications for things like video playback, frame dimensions, and bandwidth.

Step 3: The Stream

Once the connection and communication standards are established, the stream is initiated. This phase allows for essential user commands like play and pause to be executed.

What is Action Message Format (AMF) and Its Role in RTMP?

Action Message Format (AMF) is a binary serialization format originally created to speed up data exchange between Adobe Flash applications and servers. Unlike text-based formats like XML or JSON, AMF uses a compact binary structure, which allows for faster and more efficient transmission of complex data.

In 2025, while Flash is long gone from modern web use, AMF still plays a role in legacy systems and some RTMP implementations. It continues to be used in server-side environments that handle RTMP streams, especially for encoding and decoding metadata or commands sent between the encoder and streaming server.

AMF’s Role in RTMP

In RTMP (Real-Time Messaging Protocol), AMF is still used to send commands between the encoder and the RTMP server. It helps the client tell the server what to do—like start or stop a stream—and the server responds. Even though Flash is no longer used, AMF remains part of how RTMP handles real-time communication behind the scenes.

Is AMF Still Relevant Today?

As of 2025, AMF is rarely used in modern streaming workflows. With Flash fully obsolete, most platforms now rely on formats like JSON for metadata exchange. Still, AMF can occasionally be found in legacy systems or media servers that support older RTMP setups for backward compatibility.

The Death of Adobe Flash

Adobe ended support for Flash Player in December 2020, and by early 2021, all major browsers had fully blocked Flash content. As of 2025, Flash is no longer used in modern web environments. While Flash was once central to delivering interactive content, animations, and especially RTMP video playback, its retirement shifted RTMP’s role to being primarily an ingest protocol rather than a playback solution.

Why Was Flash Discontinued?

Several factors led to the demise of Flash:

• Security vulnerabilities: Flash was notorious for frequent security exploits, making it a major cybersecurity risk.
• Poor performance: Flash consumed a significant amount of system resources, leading to laggy experiences on many devices.
• Rise of HTML5: HTML5 offered a more secure, lightweight, and universally compatible alternative for video streaming and interactive content.
• Mobile incompatibility: Flash never gained full support on mobile devices, especially after Apple refused to support it on iOS.

Where Does That Leave RTMP?

Although Flash is gone, RTMP is not completely dead. Instead, it has been repurposed. While RTMP delivery (playing video over RTMP) is no longer used, RTMP ingest (sending video from an encoder to a server) is still a critical part of many live streaming workflows.

What’s the Future of RTMP?

While RTMP ingest remains widely used, newer technologies like SRT (Secure Reliable Transport) and WebRTC are emerging as alternatives due to better security, lower latency, and improved reliability over unstable networks. Over time, RTMP’s role may decline, but for now, it remains a standard protocol for live streaming setups.

Flash is fully obsolete, but RTMP still plays a key role in live streaming workflows—at least for now. Broadcasters should keep an eye on newer, more efficient protocols, but RTMP will likely stick around for years to come as a reliable ingest format.

Comparing RTMP vs. SRT vs. WebRTC

Speaking of emerging alternatives such as WebRTC, here’s a handy comparison table that highlights the key differences between RTMP, SRT, and WebRTC. This will help you understand when to use each in your streaming workflow.

This comparison shows that RTMP is still an essential part of many workflows, especially for RTMP live streaming ingest, even as SRT and WebRTC gain traction for delivery and contribution.

Furthering the above, here’s a comparison table showing you the differences between the three in terms of metrics such as latency, security, and codec flexibility.

Use Cases for RTMP in 2025

Simulcasting

RTMP is still widely used in simulcasting, where a live stream is sent to multiple platforms at once. Thanks to its broad compatibility, an RTMP live stream can easily connect with services like Facebook Live, YouTube, and LinkedIn using a single RTMP encoder. This makes it ideal for broadcasters looking to maximize reach without juggling multiple setups. Even in 2025, the RTMP protocol remains a reliable way to manage feeds across different destinations quickly and efficiently.

Church

Many churches continue using RTMP for broadcasting sermons and events. RTMP live streaming offers a cost-effective way to reach remote members with stable, real-time delivery. Since most RTMP streaming software works with affordable hardware and cloud platforms like Dacast, it’s an easy setup for small media teams. RTMP cameras also help churches maintain consistent quality without needing advanced infrastructure.

Ecommerce

In ecommerce, RTMP is often used for live product launches and flash sales. Its low-latency performance supports real-time viewer interaction, making it easier to engage customers. Businesses use RTMP streams to connect from in-store setups or mobile devices to their streaming platform. While RTMP does not support playback directly, the stream can be ingested via RTMP and delivered in HLS or WebRTC formats for smooth delivery to customers.

Corporate

Corporate events like town halls and training sessions often rely on RTMP for internal and external broadcasting. With an RTMP client and encoder, companies can stream secure content from the office to a global audience. RTMP broadcasting simplifies workflows by pushing content to a media server, which can then transcode it for modern delivery. Even with newer options available, RTMP streaming protocol remains key for businesses looking to maintain flexible and proven live video solutions.

RTMP Protocol Variations

There are several variations of RTMP, including RTMP proper and RTMPS. These video protocols serve slightly different purposes from one another in the world of live streaming.

Let’s take a look at what exactly each of these streaming protocol variations has to offer.

1. RTMP

RTMP proper is the oldest version of the RTMP protocol. This is the streaming format developed by Macromedia (later Adobe) that formed the foundation for the other standards on this list.

2. RTMPS

RTMPS streaming uses SSL certification to generate a more secure stream. Large streaming platforms like YouTube still use this variation of RTMP to protect streamers who go live on public internet servers.

RTMP Encoding

As previously mentioned, RTMP technology is typically used these days for transmitting video content from a live stream encoder to a live streaming platform. To stream with a setup that uses the RTMP protocol in this fashion, you must use an RTMP encoder.

Luckily, many of the top software encoders on the market still support RTMP, so you shouldn’t have too much trouble finding one that works for you.

Which Encoders Support RTMP?

When it comes to RTMP encoding, broadcasters have options when it comes to software encoders and hardware encoders. There are solutions for almost every need and budget.

Here’s a list of a few of the top RTMP encoder options:

• OBS Studio is free, open-source encoding software program that’s perfect for broadcasters who are new to the game. OBS offers a custom version for Dacast users.
• Wirecast is a popular software encoder from Telestream. This software starts at $599, making it better suited for more advanced broadcasters.
• VidBlaster is a live streaming software program with editing, mixing, and encoding capabilities. It’s a great option for broadcasters who are looking to add a professional touch to their streams. The software starts at $9 per year.
• vMix is another live-streaming software program with encoding capabilities and plans for every budget. Plans currently range from free to $1200 for a lifetime license.
• TriCaster is a series of encoding devices from Vizrt. This series includes both portable and stationary options.
• Teradek is a hardware company that offers an assortment of encoding devices.

For more information on how to set up an RTMP encoder, please check out our Encoder Setup Guide. You’ll learn more about how to set up your RTMP encoders and what RTMP is.

RTMP Apps for iPhone

In addition to the encoding tools we mentioned above, there are iOS apps that support RTMP streaming from your iPhone. These apps are designed for live streaming on the go.

Here are some examples of the best live streaming apps that support iOS and RTMP:

• Larix Broadcaster
• Twitch.tv
• nanoStream
• Wirecast Go
• Airmix Solo
• Broadcast Me
• LinkedIn Live

We’d like to point out that although it’s possible to stream from an iPhone smartphone, streaming with professional-grade equipment is ideal. However, if you’re streaming on-site and don’t have mobile live-streaming equipment, an iPhone or iPad can still get the job done.

For more details of iOS apps such as Twitch, TikTok, and others not mentioned here that support RTMP streaming, please check out our iOS RTMP App Comparison.

RTMP vs. RTSP: What’s the Difference?

RTSP, which is short for Real-Time Streaming Protocol, is another protocol that’s used for online, audio, video and data streaming. It’s considerably less popular than RTMP but is still important.

The main difference between them is the part of the live-streaming process that they’re each responsible for. RTMP transmits the video from the encoder to the video player, whereas RTSP controls commands between the viewers, the streaming server, and the video player.

How to Live Stream with RTMP on Dacast

Dacast automatically uses the RTMP ingest and is compatible with any RTMP encoder. That means that RTMP is a Dacast video platform’s default rather than a choice. That is how important RTMP is to the process of streaming videos.

What Dacast doesn’t support is RTMP delivery or the Adobe Flash player. The reason for this is that it uses the HTML5 video player, which is a more modern alternative. The HTML5 video player is what makes all-device streaming a possibility.

RTMP and Beyond: The Evolution of Live Streaming Protocols

While RTMP has long been the go-to protocol for live streaming, the industry has witnessed the emergence of alternative protocols that aim to address specific challenges or offer additional capabilities. Two notable examples are HLS (HTTP Live Streaming) and DASH (Dynamic Adaptive Streaming over HTTP).

HLS (HTTP Live Streaming)

HLS is an adaptive streaming protocol developed by Apple Inc. that delivers live and on-demand content over standard HTTP connections. It breaks the video stream into small, manageable chunks and adjusts the quality dynamically based on the viewer’s network conditions. HLS has gained popularity due to its broad compatibility and native support across iOS devices.

DASH (Dynamic Adaptive Streaming over HTTP)

DASH is an adaptive streaming standard developed by the MPEG industry consortium. It offers similar adaptive bitrate streaming capabilities as HLS but with broader device compatibility, supporting a wide range of operating systems and devices. DASH utilizes media presentation descriptions (MPDs) to provide dynamic stream selection and switching.

RTMP Metrics and Monitoring Tools

RTMP Metrics That Matter

To get the best results from your RTMP stream, it’s important to track a few key metrics. Dropped frame rates can signal issues with your internet or encoder settings. Ingest buffer size helps you catch delays between your encoder and the server. Bitrate stability ensures a smooth experience for your viewers.

What metrics should I monitor with RTMP ingest?

For reliable streaming, monitor:

• Dropped frames
• Ingest buffer size
• Bitrate stability

These metrics show how well your RTMP feed is performing.

Recommended tools

Tools like OBS Studio, vMix, and Dacast Analytics help track RTMP performance and keep your real time media protocol setup running smoothly.

Futureproofing Your Streaming Strategy

To stay ahead in streaming, it’s important to build a flexible setup that works today and tomorrow. While newer options like SRT and WebRTC are gaining ground, the RTMP protocol still plays a key role—especially for ingesting live video. RTMP live streaming is supported by many encoders, cameras, and apps, making it easy to use across different setups. Choosing tools that support both RTMP and newer protocols helps you adapt as tech changes. When comparing options, look at your needs—speed, compatibility, and reach—to decide if an RTMP stream still fits into your future-proof plan.

Planning for the Future Beyond RTMP

As reliable as the RTMP protocol is, businesses should plan for a streaming future that includes more than just RTMP. While the RTMP meaning is still relevant for ingest, it no longer works well for delivery. Understanding how RTMP works helps you decide when to use it, but keeping an eye on newer protocols will ensure your video strategy stays flexible.

When to Start Testing SRT or WebRTC

If your audience demands ultra-low latency or improved security, now is a good time to start testing SRT or WebRTC. These protocols offer benefits that the traditional RTMP format lacks. Try running side-by-side tests with your RTMP stream to see how next-gen options compare.

Considerations for Global Distribution/CDNs

When streaming to a global audience, it is essential to look beyond just RTMP distribution. CDNs that support HLS, DASH, and even WebRTC ensure smoother playback across regions. RTMP still plays a key role at the ingest stage, but for scalable delivery, modern options are a must.

How Businesses Can Stay Compatible with Legacy Workflows While Experimenting with Next-Gen Ingest

Many streaming setups still rely on the RTMP default port and rtmp codec standards. To futureproof, keep RTMP servers in place for legacy feeds while gradually adding SRT or WebRTC to your workflows. This hybrid approach lets you stay compatible with existing RTMP video workflows and rtmp video players, while testing newer options in parallel.

By knowing what RTMP streaming is and how RTMP works today—especially in hybrid workflows—businesses can evolve without disruption.

FAQ
