RTMP vs RTSP: Streaming Protocols Explained

Before going deeper into the RTMP vs RTSP comparison, it’s important to understand what streaming protocols are and how they work.

A streaming protocol is a set of rules that govern how audio and video data are transmitted over the Internet. These protocols break the media into smaller chunks, send them to the viewer’s device, and reassemble them for playback. They form the backbone of real-time and on-demand media delivery.

Here are some of the most common video streaming protocols used in 2025:

• HTTP Live Streaming (HLS)
• Real-Time Messaging Protocol (RTMP)
• WebRTC
• Secure Reliable Transport (SRT)
• Real-Time Streaming Protocol (RTSP)
• Dynamic Adaptive Streaming over HTTP (MPEG-DASH)

Both RTMP and RTSP streaming protocols are widely used for delivering live and on-demand content across a range of devices. Think of the video data as a vehicle and the streaming protocol as the road that guides it from the server to the viewer.

Although RTMP and RTSP serve similar purposes, the difference between RTSP and RTMP becomes clear when comparing performance, compatibility, and use cases.

What is RTMP?

RTMP allows users to view content in any web browser and on most mobile devices.

RTMP (Real-Time Messaging Protocol) is a legacy streaming protocol originally developed by Macromedia, now owned by Adobe. It was designed to efficiently transmit multimedia, especially live video, with minimal delay.

Developed by Macromedia (now owned by Adobe), RTMP streams low-latency, on-demand content efficiently. This data can be pre-recorded or live-streamed, but RTMP technology is most commonly used today for live-streamed content. Today, the RTMP protocol continues to be widely used for content ingestion (i.e., pushing the stream from an encoder to a server), even though most video playback has shifted to protocols like HLS for compatibility with HTML5 players.

How RTMP Works

RTMP is primarily used to transport audio and video data from a source (such as OBS Studio or Wirecast) to a video hosting server. From there, modern protocols like HLS deliver the content to end users across browsers and devices. Due to its simplicity and effectiveness in low-latency video streaming, the RTMP streaming protocol is still supported by most major streaming platforms, including Dacast, Wowza, and Brightcove.

Pros of using RTMP:

• Low Latency: RTMP is known for its fast delivery speeds. For businesses hosting live webinars or streaming events in real-time, low latency ensures smooth, responsive viewing experiences. This makes it ideal for RTMP vs RTSP for live streaming comparisons where latency is a key concern.
• Adaptability: RTMP supports features like DVR (pause/rewind live streams), enabling a flexible viewing experience. Viewers can join late or catch up without interruption.
• Multimedia Integration: RTMP supports various audio and video codecs and allows the blending of different media types. For example, it can simultaneously handle MP3 and AAC for audio, or MP4 and FLV for video.

Cons of Using RTMP:

• Not supported by HTML5: RTMP streams cannot be played directly in modern browsers without a conversion layer like HLS. Flash, which once enabled RTMP playback, is no longer supported in 2025, making direct browser playback a challenge.
• HTTP Incompatibility: RTMP doesn’t natively support HTTP delivery. To stream RTMP content online, you’ll need a specialized server like Adobe Media Server or a third-party RTMP server.
• Bandwidth Sensitivity: RTMP streams can suffer if internet connections are unstable or slow. Viewers may encounter interruptions or quality drops in such scenarios.

What is RTSP?

RTSP is common for CCTV and IP camera streams.

RTSP (Real-Time Streaming Protocol), is a lesser-known protocol for streaming video online. It’s widely used for IP camera and CCTV streaming, particularly in security, surveillance, and private network environments. Although it’s not as mainstream as other protocols like HLS or RTMP, RTSP plays a critical role in real-time video delivery, especially when latency and control are priorities.

The RTSP streaming protocol was designed to manage and control streaming media servers, enabling commands such as “play,” “pause,” and “record” during live broadcasts. It acts as a communication layer between the server and the viewer’s media player, helping coordinate how and when video content is delivered.

Unlike RTMP, which transmits data as part of the protocol, RTSP works by controlling the media stream; it doesn’t carry the video content itself. Instead, it relies on other protocols like RTP (Real-time Transport Protocol) to handle the actual transmission of audio and video.

RTSP is especially popular for RTSP IP camera protocol applications, allowing efficient streaming from security cameras, drones, and IoT devices in real-time.

Pros of using RTSP:

• Segmented, Real-Time Streaming: RTSP enables content to be played as it’s being downloaded, allowing viewers to watch in real-time without waiting for the full video to load. This is ideal for surveillance and monitoring scenarios.
• Custom Integration with Other Protocols: RTSP works alongside TCP and UDP, providing developers the flexibility to build custom video applications tailored to private networks or specialized environments like smart home systems.
• Low-Latency Delivery: Like RTMP, RTSP supports low-latency video streaming, making it a strong choice for time-sensitive use cases like live surveillance or remote device monitoring.

Cons of using RTSP:

• Limited Browser Support: A major drawback is RTSP browser compatibility. Most modern browsers don’t support RTSP natively. To stream RTSP content on the web, you’ll need third-party players or plugins, limiting its ease of deployment for public-facing content.
• Less Popular and Scalable: The RTSP protocol 2025 remains niche, with limited support among mainstream platforms and devices. It’s not ideal for high-traffic or commercial live events due to compatibility and scalability limitations.
• HTTP Incompatibility: RTSP, like RTMP, is not directly compatible with HTTP-based delivery, requiring special servers and custom integrations. This makes it less straightforward to implement than HLS or DASH for global distribution.

RTMP vs. RTSP: Which is Right for Your Needs?

Every broadcaster wants to ensure smooth, secure, and scalable video delivery. Whether broadcasting a live webinar or managing real-time security footage, it’s important to understand the strengths and limitations of RTMP vs RTSP. It can help you align your technology with your business goals.

While both protocols are capable of delivering real-time video content, they differ significantly in latency, browser support, scalability, and use case suitability. Below is a detailed side-by-side comparison and a practical mapping of each protocol to common business scenarios.

RTMP vs RTSP Use Case

Security Comparison: RTMP vs RTSP

Security is one of the main factors when making your decision of RTMP vs RTSP for live streaming. The RTMP streaming protocol does not include native encryption in its basic form. However, a secure version (RTMPS) encapsulates the RTMP stream within a TLS/SSL tunnel, adding encryption for better data protection. This means that while standard RTMP isn’t inherently secure, RTMPS can be used to ensure encrypted transmission and protect viewer data.

Similarly, the RTSP streaming protocol also lacks built-in encryption. By default, RTSP streams data in the clear, which poses potential security risks. To enhance security, RTSP streams can be tunneled through secure protocols (like HTTPS or VPN tunnels) to encrypt the media traffic and control signals. This approach is often used in RTSP IP camera protocol deployments, especially for surveillance or security-focused setups.

Based on this, the key differences are apparent. RTMPS is widely supported by major streaming platforms and CDNs, making it easier to implement secure live video broadcasts. In contrast, encrypting RTSP typically requires more configuration and infrastructure. We should also mention that RTSP browser compatibility is already limited. Adding encryption can further complicate streaming to web-based viewers, often necessitating specialized players.

Cloud Transcoding and RTMP

Simply put, video transcoding is the process of converting a video file from one format to another, like turning an MP4 into an FLV file to ensure wider compatibility. Using cloud transcoding instead of local encoding on your computer saves processing power, time, and money. Additionally, using cloud-based RTMP transcoding means your videos are automatically re-encoded into all necessary output formats without requiring you to handle the technical heavy lifting.

This approach ensures low-latency video streaming and seamless playback across all devices and platforms. Because RTMP allows your viewers to watch videos in multiple formats and on nearly any device, cloud transcoding ensures your content is ready for every playback scenario.

How to Convert RTMP to RTSP

Sometimes, you need to switch from one protocol to another for better compatibility. Converting RTMP to RTSP is essential when you’re working with different network conditions or devices, like surveillance systems or IP cameras. RTMP is known to excel at delivering content quickly from an encoder to a server. On the other hand, RTSP is often favored for real-time viewing on local networks, especially in RTSP IP camera protocol scenarios.

To handle the RTMP to RTSP conversion, you’ll typically need an open-source RTMP server that supports both protocols. Tools like Frigate RTMP, a popular choice for video surveillance, can simplify this process, particularly when managing multiple simultaneous streams.

The key difference between RTMP and RTSP lies in how they’re used. RTMP is optimized for live broadcasts, providing low-latency video streaming for real-time events. RTSP, meanwhile, is designed to control and deliver real-time video streams to viewers and devices, and it’s especially common in security and RTSP IP camera applications.

• HTTP Live Streaming (HLS): It is the most scalable and browser-friendly protocol, but it typically has higher latency (5–30 seconds). It’s an excellent choice for large-scale content delivery to a global audience.
• Open Network Video Interface Forum (ONVIF): This is a global standard for ensuring interoperability between IP-based security devices like cameras, recorders, and video management systems. It allows different devices from different manufacturers to work together seamlessly. While ONVIF itself is not a streaming protocol like RTMP or RTSP, it uses protocols like RTSP and HTTP within its framework. This standard is widely adopted in the security and surveillance industry for device compatibility and easy integration.

Now, let’s have a closer look at the key factors that make RTMP and RTSP different from their alternatives. 

Relevance of RTMP in 2025 and Beyond

Despite RTMP no longer being viable for direct browser playback, RTMP streaming protocol workflows remain essential for live video ingest. Modern broadcasters still use RTMP to send streams from encoders like OBS Studio or hardware encoders to platforms such as Dacast. It then converts RTMP to HLS or MPEG-DASH for reliable and adaptive playback across all devices.

RTMP’s enduring popularity lies in its simplicity, low latency (around 3–5 seconds for most workflows), and robust ecosystem of encoders and media servers. While alternatives like WebRTC and SRT are gaining traction for low-latency video streaming and advanced security, RTMP is still the default for ingest.

For IoT and security deployments, the difference between RTSP vs RTMP comes into play.
