All About RTSP Streaming 2025

Live videos are trending because everything happens in real-time these days. For this reason, a proper streaming experience is important, which brings us to RTSP streaming. It promises high-quality but low-latency video over a network.

It's a reliable solution for people who need to stream events, sports games, church services, and more. It's a good option if you have to manage the security systems because it gives flexibility and stability. So, we are sharing the guide to RTSP streaming and how you can set it up for great streaming!

Part 1: What is RTSP Streaming?

To begin with, RTSP is the Real Time Streaming Protocol. It is basically a network protocol that helps set up and control the video sessions between different endpoints. We don’t mind saying that it's a remote control for media servers. That's because you can play, pause, and stop the video streaming without downloading anything.

While HTTP-based streaming (like HLS or DASH) is more common for internet delivery, RTSP is still widely used for IP cameras, security feeds, and professional live production because of its low latency and real-time interaction capability.

RTSP Usage Scenarios：

• Live Streaming: Using RTSP to push real-time video from cameras or capture devices to a streaming server for multiple viewers.

• Local Network Video Surveillance: For example, surveillance cameras transmit live video streams to monitoring centers or recording devices via RTSP, offering low latency and high stability.

• Remote Video Viewing: Remote users access RTSP URLs over the internet to watch surveillance footage or live content in real time.

• Multi-Device Video Transmission: Distributing video streams via RTSP to multiple clients.

Part 2: How RTSP Works?

RTSP works using a client-server model:

• RTSP Server:  It can be the source providing the video feed (e.g., a camera or media server).
• RTSP Client: It can be the receiving application or device (e.g., VLC, OBS Studio).
• Transport Protocols: It typically uses RTP (Real-time Transport Protocol) over UDP or TCP to deliver the actual audio/video data.

The process usually follows this sequence:

• Client sends a request to the RTSP server to start streaming through RTSP software.
• Server responds with the details of the media stream.
• RTP packets carry the video/audio data.
• Client can send commands like PLAY, PAUSE, or TEARDOWN.

Part 2: How to Set Up RTSP Streaming

This guide is designed for illustrative purposes — actual steps may vary depending on your device model, network configuration, and streaming software.

RTSP is a versatile protocol that can be integrated into a wide variety of production environments, and this example shows how to connect OBSBOT Tail 2 over a local network using RTSP in OBS Studio.

Step 1: Enable RTSP Mode in OBSBOT Tail 2

1. Open OBSBOT Center on your computer or Obsbot Start on your smartphone. (These are official applications designed for managing and controlling the Tail 2 and are compatible.)
2. Connect your OBSBOT Tail 2 via USB, Wi-Fi, or Ethernet.
3. Go to Settings by clicking the "More Settings" or gear icon.
4. Find and turn on the RTSP mode. (Note: Once RTSP is enabled, other video output modes like UVC or NDI will be disabled.)
5. Navigate to General Settings > About Device to view the RTSP video stream address.
6. Based on your connection (wired or wireless), copy the RTSP URL, such as: rtsp://192.168.1.xxx:8554/live
   This URL will be used to fetch the video stream in OBS Studio.

Step 2: Connect OBSBOT Tail 2 to OBS Studio via RTSP

Make sure both OBSBOT Tail 2 and your computer are connected to the same local network.
There are two main ways to import the RTSP stream into OBS Studio:

Method 1: Using Media Source

1. Open OBS Studio
2. In the Sources panel, click the "+" button and select "Media Source"
3. Create a new source name (e.g., Tail2 RTSP) and click OK
4. In the settings window:
   • Uncheck "Local File"
   • In the Input field, paste the RTSP stream address copied earlier
   • Optionally, check "Use hardware decoding when available"
   • Set Buffering to minimal for low latency
5. Click OK. You should now see the live feed from OBSBOT Tail 2 inside OBS

Method 2: Using VLC Video Source

If you have VLC media player installed:

1. Open OBS Studio
2. In the Sources panel, click the "+" button and select "VLC Video Source"
3. Create a new source and click OK
4. In the VLC source settings:
• Click the "+" under the playlist area and choose "Add Path/URL"
• Paste your RTSP stream address and confirm with OK
• Your stream will now appear in the VLC source playlist
• Click OK again to finalize the setup
5. OBS will now begin receiving the RTSP feed from OBSBOT Tail 2

Step 3：Now Streaming via RTSP

At this point, the RTSP stream is successfully integrated into OBS Studio. From here, you can:

• Go live to platforms like YouTube, Twitch, or Facebook via OBS
• Record the incoming stream locally
• Switch between sources, apply filters, or mix multiple feeds for a more dynamic live production

Part 3: FAQs About RTSP Streaming

1. Which browsers support RTSP?

Most modern browsers do not support RTSP natively. You need a media player like VLC or an embedded player that transcodes the stream.

2. Is RTSP still being used?

Yes. It remains popular for IP cameras, local network streaming, and professional live production.

3. Do all IP cameras support RTSP?

No. Some consumer-grade cameras use proprietary protocols. Always check the manufacturer's specs.

4. What is the RTSP stream URL?

It's the address format used to fetch a live stream from an RTSP server, usually starting with rtsp:// followed by the IP address and port.

5. What's the difference between ONVIF and RTSP?

ONVIF is a standard for camera control and discovery. RTSP handles the actual media streaming. Many devices use both together.

Conclusion

RTSP streaming continues to be a go-to protocol for professionals who demand real-time, high-quality video delivery, especially in controlled network environments. It's low latency, compatibility with pro-grade hardware, and direct control over streaming make it indispensable. Paired with an advanced camera like the OBSBOT Tail 2, RTSP becomes not just a tool but a creative powerhouse for broadcasting, production, and live events.
