RTMP Server Hosting: What It Is and How to Access It
Table of Contents
RTMP has played an important part in the history of streaming video over the internet. As streaming technology has developed, RTMP has transitioned out of the original role that it served into a new one that works better with more modern live streaming setups.
In particular, RTMP server hosting has become much more important over the past couple of years. The importance stems from the fact that this technology makes it easy for broadcasters to stream with low latency which improves the viewer experience.
Today, we’re going to discuss everything broadcasters need to know about RTMP server hosting. We will discuss what RTMP server hosting is and how you can access an RTMP server host for your streaming needs. We’ll also cover the connection between RTMP and HLS, and how this is relevant to broadcasters.

What is RTMP?
Real-Time Messaging Protocol (RTMP) is a transport protocol that is used to move video files from one part of the live streaming workflow to the next. RTMP was designed by Macromedia, which is now owned by Adobe, to deliver video content to the Adobe Flash player.
RTMP is now most widely used for RTMP ingest rather than delivery since it is not compatible with HTML5 video players, which are the industry standard.
RTMP is known for its low latency streaming capabilities. It maintains a constant connection and splits streams into smaller chunks to transmit over the internet. RTMP uses the constant connection between the source and destination to determine the appropriate size of these chunks to send.
There are a few variations of RTMP that serve slightly different purposes. These include RTMPE, RTMPT, RTMFP, and RTMPS. The “regular” RTMP is referred to as “RTMP proper” when being compared or discussed in terms of these other variations. RTMPS is particularly valuable for streaming on mobile devices over public internet networks since it is encrypted with an extra layer of security.
RTMP and HLS: How Do They Work Together?
Before we dive into the ins and outs of RTMP streaming server hosting, there are few things that we need to clarify.
First, Flash is dead, but RTMP most certainly is not. HTML5 video players have become the standard in video streaming since they are compatible with just about any device and operating system. They are also very easily customizable, which is important for broadcasting at the professional level.
Streaming with an HTML5 video player requires HLS delivery. The HTML5 video player and HLS protocol were developed to meet the growing need for a set that is compatible with accessing online video content from a mobile device. HTML5 and HLS made up for gaps and deficiencies that were left in the Adobe Flash player.
Simply put, HLS is to HTML5 as RTMP was to Flash player.
RTMP is still used in setups that use HLS delivery to an HTML5 video player, but its role is a little different. In this situation, RTMP is used for ingesting. That means that it is used to feed video files from an encoder or another source to an online video player or even directly to a CDN.
The beauty of the HLS/RTMP duo is that it can produce streams with low latency, high compatibility, and reliable security. It is possible to stream with HLS delivery and HLS ingest, but this setup doesn’t support low latency as the alternative does.
RTSP, which is short for “Real-Time Streaming Protocol,” is another important protocol that is often throwing into this mix. Many confusing it as an RTMP alternative, but it typically plays a different role in the live streaming process, primarily when it has to do with video player commands.
However, RTSP can be used in encoding in some cases. Some platforms use a workflow that uses an RTSP to RTMP conversion to make ingest compatible with some sources, such as IP cameras.
What is an RTMP Server?
An RTMP server is the technical setup that is used to receive an RTMP data stream via RTMP ingest. Basically, an RTMP server is equipped with the necessary tools to receive and decode video files that are being transported from an encoder or other source.
RTMP servers are created based on standard server technology, and they are often built into your online video platform or the platform that you’ve created to self-host your video content.
By using an RTMP server and RTMP ingest, broadcasters can tap into the benefits of RTMP as a protocol even when they are using HLS streaming to deliver their content.
RTMP Server Uses
In general, RTMP servers are used to offer support for RTMP ingest. This comes in handy for several different use cases.
One of the most notable uses of an RTMP server is to connect with RTMP encoders. RTMP encoders are both cheap and accessible, which is not yet the case for HLS encoders. This gives you the flexibility to choose between quite a variety of software and hardware encoders with a wide range of functionality and price points.
With RTMP ingest, you can connect sources in advance so that everything is in place to go live at a scheduled time. This is something that comes in handy for new programs that do linear broadcasting. This setup also works well with IP camera streams and webcam streams.
RTMP servers are also used for uploading video content to create video on demand (VOD) libraries with dynamic content.
Again, it is important to reiterate that RTMP ingest via an RTMP server gives broadcasters the ability to stream with low latency. This is really important for certain types of events, like webinars, conferences, sporting events, church services, and other streams that could call for participation from an audience. Low latency streaming helps virtual events to feel more lifelike since it helps viewers to experience the happenings in real-time.
Some additional benefits of using RTMP as part of your streaming setup include reduced buffering and adaptive bitrate streaming. It also gives users the ability to fast forward and rewind some content on some video players.
How to Access RTMP Server Hosting
There are a couple of methods for accessing RTMP server hosting. Many broadcasters use an online video platform that is equipped with an RTMP server, and others build their own.
Let’s take a close look at each of these methods.
Via an Online Video Platform
An easy way to access RTMP server hosting is through a professional online video platform, like Dacast. You’ll want to specifically look for a professional streaming platform that supports RTMP ingest and has RTMP servers.
This approach is a favorable one because it doesn’t involve much technical know-how or support from an experienced developer. The RTMP server hosting happens behind the scenes, so connecting your RTMP-compatible sources is as simple as copying and pasting a URL.
Since everything is automatically handled by the online video platform’s developers, you don’t have to invest money and other resources in hiring a developer or purchasing the supporting software.
Aside from Dacast, some online video platforms that support RTMP ingest and have RTMP servers include Brightcove, Wowza, IBM Cloud Video, Panopto, and more. Kaltura uses RTSP to RTMP ingest, but it is not clear if the platform supports RTMP ingest independent of the RTSP conversion or with RTMP servers.

Create Your Own RTMP Server
If you are not using an online video platform, it is possible to host an RTMP server of your own. Some development experience will come in handy, so if you don’t have that experience yourself, it is wise to hire someone who does. Either way, there are a few tools you can lean on to go about this.
Developers first need to choose a server building tool to create their RTMP server. Adobe Media Server, Red 5, Wowza’s Live Streaming, and Nginx engine are four of the top offerings. These software options are paid, but you may be using one or more of them for other operations.
The process for creating an RTMP server will vary depending on the tools you use. We recommend checking out Doug Johnson’s RTMP server setup video tutorial for a technical walkthrough of this process with Nginx.
One benefit of creating your own RTMP server is that you have the power to adjust it to meet your specific needs. This comes into play when you are streaming different types of events that require different levels of latency.
For example, if you are concerned about a potential mishap (think wardrobe malfunction, foul language, or sharing of improper information), a little latency is helpful. However, if you’re focusing on peer-to-peer streaming, the lower the latency, the better.
Again, this approach is much more technical and will likely require support from a developer with relevant experience.
RTMP server hosting is important for broadcasters that want to use encoders, video sources, and other supporting software that requires RTMP ingest. As a broadcaster, you can opt to host the RTMP server through our OVP or build one of your own.
Accessing RTMP server hosting through an OVP is typically both convenient and affordable. It requires less technical know-how, which is definitely a plus.
