If you’ve ever set up a stream, you’ve likely come across terms like RTMP and SRT. These are two popular protocols that help send your video from your device to the internet for others to watch. But they work differently, and choosing the right one can make a big difference in your streaming experience.
In this article, we’ll explore RTMP vs SRT in a simple and friendly way. We’ll cover what each protocol does, their strengths and weaknesses, and how they fit into your streaming setup, especially if you’re using a platform like Omnistream. By the end, you’ll have a clear idea of which one to pick for your next stream.
We have already covered what RTMP is in an article and what SRT is in another video. This article is about bringing both together and understanding the differences.
Before we dive into the details, let’s talk about what a streaming protocol is. Think of it as a set of rules that tells your video how to travel from your computer or camera to your viewers. It’s like a road map for your stream. RTMP and SRT are two different maps, each with its own way of getting the job done. Knowing how they work can help you decide which one suits your needs, whether you’re streaming casually or aiming for a professional setup.
RTMP stands for Real-Time Messaging Protocol. It’s been around since the early 2000s, created by Macromedia, which Adobe later acquired. Back then, live streaming was just starting to take off, and RTMP became the standard way to deliver video and audio over the internet in real time. It’s widely used because it’s reliable and supported by almost every streaming tool and platform out there.
When you use RTMP, your video data gets broken into small packets and sent over the internet using something called TCP, or Transmission Control Protocol. TCP is great because it makes sure every packet arrives at its destination. If one gets lost, it’s sent again. This works well for most streams, but it can slow things down. If your internet connection for streaming isn’t perfect, you might notice delays or buffering. That delay between what you’re doing and what your viewers see is called latency, and with RTMP, it’s usually around 5 to 30 seconds.
RTMP is super easy to use, especially if you’re new to streaming. Tools like OBS (Open Broadcaster Software) and Omnistream have RTMP built in, so you just plug in a stream key from your platform, and you’re good to go. It’s also compatible with tons of services, from YouTube to Twitch. But as internet speeds and streaming demands have grown, RTMP’s limitations have become more noticeable, especially when it comes to handling tricky network conditions or keeping latency low.
SRT, or Secure Reliable Transport, is a newer protocol that came onto the scene in 2012, thanks to a company called Haivision. It was designed to tackle some of the challenges RTMP faces, like high latency and unreliable connections. SRT is built for today’s streaming world, where people expect fast, smooth video even on less-than-ideal networks.
Unlike RTMP, SRT uses UDP, or User Datagram Protocol, to send data. UDP is faster because it doesn’t wait around to resend lost packets. Instead, SRT has its own smart system to handle errors and keep the stream flowing. This means lower latency, often less than a second, which is a big deal if you’re doing something interactive like gaming or a live Q&A. Plus, SRT can adapt to shaky internet connections, so your viewers are less likely to see buffering or dropped frames.
Another cool thing about SRT is its security. It comes with built-in encryption, which keeps your stream safe from anyone who might try to peek in. This is handy if you’re streaming private events or just want extra peace of mind. And since SRT is open-source, it’s free for anyone to use and improve. That’s why it’s catching on fast with streamer, which value its flexibility and performance.
Now that we’ve got the basics, let’s compare RTMP vs SRT side by side. This will help you figure out which one matches your streaming goals.
Latency is all about speed, how quickly your viewers see what you’re doing. If you’re streaming something where timing matters, like playing a game or chatting live, you want low latency. RTMP’s latency is higher because of how TCP works. It prioritizes getting every packet delivered, even if it takes a little longer. That’s why you might see delays of 5 seconds or more.
SRT, with its UDP approach, cuts that delay way down. It can get your stream to viewers in under a second. That’s a huge advantage for real-time interaction. So, if you’re on Omnistream hosting a live event like a church streaming or a wedding, where every second counts, SRT might be your best bet.
Streaming isn’t always smooth sailing. Sometimes your internet drops or gets spotty. RTMP can struggle here. If packets get lost, TCP stops to resend them, which can lead to buffering or choppy video. It’s not ideal if you’re streaming from a coffee shop or a rural area with weak Wi-Fi.
SRT is built to handle these hiccups. Its error-correction system keeps the stream going even if some data goes missing. This makes it more reliable in tough conditions. For streamers on Omnistream who travel or stream from different locations, SRT could save the day.
Security might not be the first thing you think of, but it’s important. RTMP doesn’t have encryption built in, so your stream could be vulnerable unless you add extra protection. That’s not a huge deal for public streams, but it’s something to consider for private content.
SRT, on the other hand, encrypts your data right out of the box. That means your stream is secure without any extra steps. If you’re using Omnistream for a business meeting or a personal event, SRT’s security gives you one less thing to worry about.
RTMP has been around forever, so it works with pretty much every streaming platform and software. Whether you’re sending your stream to Facebook, YouTube, or Omnistream, RTMP is a safe choice. It’s the default for a reason, it’s everywhere.
SRT is newer, so it’s not as widely supported yet. But it’s gaining ground fast. Platforms like Omnistream already use it, and more are jumping on board. If your favorite service doesn’t support SRT, you might need to stick with RTMP for now. The good news? Omnistream gives you both options, so you’re covered either way.
Both RTMP and SRT are pretty straightforward, especially with the right tools. RTMP is the easier one for beginners because it’s so common. Most streaming software has RTMP ready to go—just enter your stream key, and you’re streaming.
SRT might take a tiny bit more setup, like adjusting a few settings. But it’s not hard, especially on Omnistream that’s designed to make it simple. If you’re comfortable tweaking things, SRT won’t slow you down. And once it’s set up, the performance boost might make it worth the effort.
RTMP is a tried-and-true option that still works great for lots of streamers. Here’s when it might be the right choice for you:
For casual streamers on Omnistream, RTMP is a dependable pick that gets the job done without any fuss.
SRT shines when you need top performance or face challenging conditions. Here’s when it’s the better option:
So, RTMP vs SRT, which should you use? It depends on what you’re after. RTMP is your go-to for simplicity and compatibility. It’s been around forever, and it works everywhere. SRT is the modern pick for speed, reliability, and security. It’s built for today’s streaming demands and handles tough situations like a champ.

RTMP is an older protocol that’s super common but can have higher latency and trouble with bad internet. SRT is newer, faster, and more reliable, with lower latency and built-in security. It’s a tougher choice for modern streaming needs.
Not by much. RTMP is often ready to go in most streaming tools, which makes it a bit simpler for beginners. SRT might need a few extra steps, but platforms like Omnistream make it easy to configure. Once you get the hang of it, it’s no big deal.
Not yet. RTMP works everywhere because it’s so established. SRT is still growing, but lots of platforms, including Omnistream, support it. Check your platform’s options—if SRT’s there, it’s worth a try for better performance.
SRT’s low latency is the key. In gaming, you want your viewers to see your moves as they happen, especially if they’re chatting or reacting live. RTMP’s delay can feel sluggish, while SRT keeps things snappy and real-time.
Omnistream supports both protocols, so you can switch between them easily in your settings. We also give you tools to monitor your stream’s performance, like latency and quality, so you can see what works best for you. Our support team is there to guide you, too!
