The real-time messaging protocol is one of the most popular protocols for streaming service providers around the world. In simple terms, this protocol is widely famous for its diverse nature and set of principles for formatting purposes.

In the initial stages of development, Macromedia is the creator of this protocol and has been in service for a long time. The protocol is also famous for enhancing low-latency connections for smoother streaming without any buffers.

This blog will tell you about the role of this protocol in boosting the productivity of live streaming events. In addition to this, we’ll also describe the workings of this protocol with live streaming platforms.

What Is RTMP: Everything You Need To Know 

It was in the year 2002 that this protocol came into the picture for playing audio and video files over the internet. Furthermore, the primary function of this platform evolved into the smooth transmission of large amounts of data for playback in the users’ video players.

In the current scenario, the protocol finds its use as an open-source protocol for the delivery of data to the host. In addition to this, it also takes help from the encoder during the transfer process. The huge demand for this protocol is due to the smart balancing of TCP between video players and the server.


RTMP supports low latency streaming for events, which makes the streaming better than ever for the audience. In addition to this, users with lower bandwidths can also view the live-streaming session without any buffer. So, let’s have a quick recap on some of its features – 

  • RTMPS :The version is sent over TLS/SSL and RTMPS is used to create secure connections.
  • RTMPE: is commonly used for real-time protection of content and is defined as an encrypted version of RTMP.
  • RTMFP:  this version stands for real-time message flow protocol. It is a common form of secure UDP-based protocol for network communication.


Here are a few quick points about how the RTMP live stream functions that will aid you in understanding how the protocol operates:  

  • The live video feed, which is thus recorded by the camera and sent to the server with the aid of an encoder, constitutes the first step. The whole process is also known as the “first mile”
  • The scaled video is then distributed over the internet and then delivered to the user’s device using a content delivery network (CDN). This process is known as the “last mile”
  • Nowadays, RTMP is not used frequently for the last-mile process.
  • Leading low latency video streaming providers use it as their preferred method for the first process. because large amounts of data were divided into smaller pieces and sent separately via different virtual channels during the segmentation process.
  • For the last-mile delivery at the user end, RTMP is not used in the current scenario. However, below are some famous alternatives for RTMP streaming – 

Alternatives To RTMP For Last Mile Contribution 

Here are some of the popular alternatives for the last-mile contribution. In the case of last-mile delivery, an RTMP live stream transmits data between dedicated servers and video devices that use Flash Player.


HLS is one of the most famous streaming protocols and finds its use in mobile devices, web browsers, and other computing devices as well. Scaling is very easy on this platform, which is a great advantage to this protocol. In addition to hosting live streaming sessions, HTTP uses ABS functionality. This has a very crucial role to play in events as it automatically adjusts the video quality based on the viewer’s bandwidth availability. In addition to this, most of the live streaming platforms are using this protocol for last-mile delivery purposes.


MPEG is famous under the name “Moving Pictures Expert Group.” In addition to this, the MPEG protocol has also set up new standards for audio and video for the industry. It is a codec-agnostic protocol that is open source. The major highlights of this protocol include higher latency, ranging from 6 seconds to 30 seconds.

Benefits Of RTMP Streaming 

  • There are many inexpensive software-based encoders available, and frequently low-cost hardware solutions are also available. Encoders are simple to set up.
  • As opposed to many chunks, it is delivered as a single file, which is simpler to manage and process.
  • Since RTMP has been the industry standard for such a long time, there are numerous tools and resources available to support it, making it less expensive to set up and simpler to maintain.
  • It remains one of the fastest options available in the industry so far for every backstage operation during the ongoing live event.

RTMP For First Mile Delivery 

There are mostly two types of use cases for RTMP streaming. For the live streaming of events, most of the live streaming platforms prefer RTMP for the first mile of delivery. Additionally, the second case is “last mile delivery.” RTMP does not support modern codecs, which is why alternatives to this protocol exist.

Coming back to the first-mile delivery, it happens after you transfer the footage from the source to the encoder, and then the encoder will convert to RTMP eventually. Wherever the encoder is sending the RTMP content it is “fcontent,irst-mile delivery.” It is simple to use, affordable, famous around the world, and trustworthy. But last-mile delivery is not possible with this platform. You need a protocol for last-mile delivery that will be quick, high-quality, and adaptable to any environment, including mobile browsers. Everyone eventually transcodes to HLS because of this.

Let’s Conclude 

RTMP is a technical mechanism for streaming video material at its core. The biggest benefit is that streamers may broadcast everywhere and anywhere. Because it is universal across various platforms, including social ones like Facebook, Youtube, and Linkedin. You also have a safe option for cloud-based streaming at your disposal with RTMPS.

Many online event platforms are preferring this out-of-date protocol over modern-day codes for first-mile delivery purposes. It has been cost-efficient and trustworthy for many years.
