Okay, here’s a comprehensive article on streaming with MediaMTX, aiming for approximately 5000 words. This will cover a wide range of topics, from basic setup to advanced configurations and troubleshooting.

Streaming with MediaMTX: A Comprehensive Guide

MediaMTX (formerly known as rtsp-simple-server) is a powerful, versatile, and open-source media server that supports a wide array of streaming protocols, making it an excellent choice for various applications, from home surveillance to professional broadcasting. This guide will delve into the details of setting up and using MediaMTX for streaming, covering everything from basic configurations to advanced features and troubleshooting common issues.

1. Introduction to MediaMTX

  • What is MediaMTX? MediaMTX is a ready-to-use, zero-dependency media server and RTSP proxy. Its core strength lies in its ability to ingest, manage, and distribute media streams using various protocols, primarily focusing on RTSP (Real-Time Streaming Protocol) but also supporting RTMP (Real-Time Messaging Protocol), HLS (HTTP Live Streaming), WebRTC (Web Real-Time Communication), and SRT (Secure Reliable Transport).

  • Why Choose MediaMTX?

    • Open Source and Free: MediaMTX is completely free and open-source, meaning you have full access to the code, can contribute to its development, and are not bound by licensing fees.
    • Zero Dependencies: It’s designed to run without requiring external libraries or complex installations, making deployment incredibly simple. A single executable file is often all you need.
    • Cross-Platform Compatibility: MediaMTX runs smoothly on Linux, Windows, macOS, and even on embedded systems like Raspberry Pi, offering great flexibility in deployment environments.
    • Multiple Protocol Support: As mentioned above, its ability to handle RTSP, RTMP, HLS, WebRTC, and SRT makes it adaptable to different streaming needs and client devices.
    • RTSP Proxy Functionality: MediaMTX can act as an RTSP proxy, aggregating multiple RTSP streams and providing a single point of access, simplifying network configuration and reducing load on individual cameras.
    • Configuration Flexibility: A configuration file (usually mediamtx.yml) allows fine-grained control over every aspect of the server, from network settings to stream parameters.
    • API and Web UI: MediaMTX provides a REST API and a built-in web interface for monitoring and managing streams, making it easy to integrate with other systems or manage the server remotely.
    • Active Community and Development: The project has an active community and is continuously being developed, ensuring ongoing improvements and support.

  • Use Cases:

    • IP Camera Streaming: The most common use case is aggregating and redistributing streams from IP cameras, enabling features like recording, remote access, and integration with home automation systems.
    • Live Streaming: MediaMTX can be used for live streaming events, webinars, or gaming sessions using RTMP or SRT as input and HLS or WebRTC for output.
    • Media Distribution: It can serve as a central hub for distributing pre-recorded video content to multiple clients.
    • Low-Latency Streaming: With protocols like WebRTC and SRT, MediaMTX can be employed in scenarios requiring minimal latency, such as video conferencing or remote control applications.
    • Security and Surveillance: Used in conjunction with motion detection software, MediaMTX can form the backbone of a robust security and surveillance system.

2. Installation and Basic Setup

This section will guide you through the installation process on different platforms and the initial configuration.

  • Installation:

    • Linux (using pre-compiled binaries):

      1. Download: Go to the MediaMTX releases page on GitHub (https://github.com/bluenviron/mediamtx/releases) and download the appropriate archive for your system architecture (e.g., mediamtx_vX.Y.Z_linux_amd64.tar.gz for 64-bit Linux).
      2. Extract: Extract the archive: tar -xzf mediamtx_vX.Y.Z_linux_amd64.tar.gz
      3. Move (Optional): You can move the mediamtx executable to a location in your system’s PATH (e.g., /usr/local/bin) for easier access: sudo mv mediamtx /usr/local/bin/
      4. Create Configuration File: Create a mediamtx.yml file in a suitable location (e.g., /etc/mediamtx/, your home directory, or the same directory as the executable). We’ll populate this file later.

    • Linux (using Docker): Docker provides the easiest and most consistent way to run MediaMTX.

      1. Install Docker: If you don’t have Docker installed, follow the instructions for your distribution from the official Docker website.

      2. Run the Container:
        bash
        docker run --rm -it -p 8554:8554 -p 1935:1935 -p 8888:8888 -p 8889:8889 bluenviron/mediamtx
        This command runs a temporary container (removed when stopped with --rm), maps the necessary ports (8554 for RTSP, 1935 for RTMP, 8888 for HLS, 8889 for WebRTC), and uses the bluenviron/mediamtx image from Docker Hub. This doesn’t persist configuration changes.

      3. Persistent Configuration (Docker): For persistent configuration, you’ll need to mount a volume for the configuration file:
        bash
        docker run -d --name mediamtx -p 8554:8554 -p 1935:1935 -p 8888:8888 -p 8889:8889 -v /path/to/your/mediamtx.yml:/mediamtx.yml bluenviron/mediamtx
        Replace /path/to/your/mediamtx.yml with the actual path to your configuration file. The -d flag runs the container in detached mode (in the background).

    • Windows:

      1. Download: Download the Windows release from the GitHub releases page (e.g., mediamtx_vX.Y.Z_windows_amd64.zip).
      2. Extract: Extract the ZIP file to a directory of your choice.
      3. Create Configuration File: Create a mediamtx.yml file in the same directory as the mediamtx.exe executable.
      4. Run: Open a command prompt in the directory and run mediamtx.exe.

    • macOS: Similar to Linux, download the macOS release from GitHub, extract it, create a mediamtx.yml file, and run the mediamtx executable from the terminal.

  • Basic mediamtx.yml Configuration:

    Here’s a minimal mediamtx.yml configuration to get you started:

    “`yaml

    General settings

    logLevel: info # Log level (debug, info, warn, error)
    logDestinations: [stdout] # Log destinations (stdout, file, syslog)
    readTimeout: 10s # Read timeout
    writeTimeout: 10s # Write timeout

    RTSP server settings

    rtsp:
    protocols: [tcp] # Supported RTSP protocols (tcp, udp, multicast)
    encryption: no # Enable RTSP encryption (yes, no, optional)

    RTMP server settings (Optional, if you need RTMP)

    rtmp:
    enabled: no # Enable RTMP server (yes, no)

    HLS server settings (Optional, if you need HLS)

    hls:
    enabled: no # Enable HLS server (yes, no)

    WebRTC server settings (Optional, if you need WebRTC)

    webrtc:
    enabled: no # Enable WebRTC server (yes, no)

    Paths (streams) configuration

    paths:
    all: # This is a special path that acts as a proxy for all other defined paths
    source: publisher # Source type (publisher, rtsp://…, rtmp://…, etc.)
    sourceOnDemand: yes # Start the source only when a client connects
    “`

    • Explanation:
      • logLevel: Controls the verbosity of the logs. info is a good starting point.
      • logDestinations: Specifies where logs should be written. stdout directs logs to the console.
      • readTimeout and writeTimeout: Timeouts for network operations.
      • rtsp, rtmp, hls, webrtc: Sections to configure each protocol. Enable only what you need.
      • paths: This is where you define your individual streams. The all path is special; it acts as a catch-all proxy.
      • source: publisher: This means the server will wait for a source (like an IP camera or OBS Studio) to publish a stream to it.
      • sourceOnDemand: yes: This setting is crucial for efficiency. It means the source (e.g., your IP camera) will only be accessed when a client connects to view the stream, saving bandwidth and resources.

  • Running MediaMTX:

    • Linux/macOS (without Docker): From the terminal, navigate to the directory containing mediamtx and run: ./mediamtx (or just mediamtx if you moved it to your PATH).
    • Windows (without Docker): Open a command prompt in the directory containing mediamtx.exe and run: mediamtx.exe
    • Docker: Use the docker run commands provided earlier.

    After running MediaMTX, you should see some log output in the console indicating that the server is running. At this point, it’s waiting for a stream to be published to it.

3. Publishing Streams to MediaMTX

Now that MediaMTX is running, let’s look at how to send streams to it. We’ll cover common scenarios:

  • From an IP Camera (RTSP):

    1. Find the Camera’s RTSP URL: This is the most crucial step. The RTSP URL is specific to your camera model and often requires consulting the camera’s manual or manufacturer’s website. It typically looks like this:
      rtsp://[username]:[password]@[camera_ip_address]:[port]/[path]

      • [username] and [password]: The camera’s login credentials.
      • [camera_ip_address]: The local IP address of your camera.
      • [port]: The RTSP port (usually 554, the default).
      • [path]: A camera-specific path that identifies the stream (e.g., /live, /h264, /stream1). This is the part that varies the most between camera models. Examples:

    2. Configure MediaMTX (Method 1 – publisher): Using the publisher source type in the mediamtx.yml (as shown in the basic configuration), you don’t need to specify the camera’s RTSP URL in the configuration file itself. MediaMTX will wait for the camera to “announce” its stream. However, some cameras don’t automatically announce. For these, you’ll use Method 2.

    3. Configure MediaMTX (Method 2 – rtsp:// source): If your camera doesn’t announce, or you prefer to explicitly define the source, modify the mediamtx.yml like this:

      yaml
      paths:
      camera1: # Give your stream a descriptive name
      source: rtsp://admin:[email protected]:554/live # Replace with your camera's RTSP URL
      sourceOnDemand: yes
      Replace rtsp://admin:[email protected]:554/live with your camera’s actual RTSP URL. The camera1 is a path name that you’ll use to access the stream later.

    4. Restart MediaMTX: After making changes to mediamtx.yml, restart the MediaMTX server for the changes to take effect.

  • From OBS Studio (RTMP):

    OBS Studio is a popular open-source software for live streaming and recording. It can publish streams using RTMP.

    1. Enable RTMP in mediamtx.yml:
      yaml
      rtmp:
      enabled: yes
      # You can customize RTMP settings here, but the defaults are usually fine.

    2. Configure OBS Studio:

      • Open OBS Studio and go to Settings -> Stream.
      • Select Service: Custom....
      • For Server, enter: rtmp://[mediamtx_ip_address]:1935/live
        Replace [mediamtx_ip_address] with the IP address of the machine running MediaMTX. If it’s on the same machine, use localhost or 127.0.0.1.
      • For Stream Key, enter a name for your stream (e.g., obs_stream). This will be part of the path you use to access the stream.
      • Click OK and start streaming from OBS Studio.

    3. Configure MediaMTX Path (If Necessary):
      By default if you are publishing to /live/<stream_key>, the stream will be available at path <stream_key>. If, however you want a different path, you can use the runOnPublish directive, in order to start a shell script when a publisher connects:

      “`yaml
      paths:
      obs_stream:
      runOnPublish: |
      # This script is executed when a publisher connects to /live/obs_stream
      # You can use this to perform actions like starting a recording.
      echo “Publisher connected to /live/obs_stream”

        # Since we provided runOnPublish, we no longer need to define "source".
  sourceOnDemand: yes

      “`

  • From FFmpeg (RTSP, RTMP, etc.):

    FFmpeg is a powerful command-line tool for handling multimedia. You can use it to publish streams to MediaMTX from various sources, including files, webcams, and screen captures.

    • Example 1: Publish a video file as an RTSP stream:

      bash
      ffmpeg -re -i input.mp4 -c copy -f rtsp -rtsp_transport tcp rtsp://localhost:8554/file_stream
      * -re: Read input at the native frame rate (important for live streaming simulation).
      * -i input.mp4: Specify the input file.
      * -c copy: Copy the video and audio streams without re-encoding (fast and efficient).
      * -f rtsp: Specify the output format as RTSP.
      * -rtsp_transport tcp: Use TCP for RTSP transport (more reliable than UDP).
      * rtsp://localhost:8554/file_stream: The RTSP URL to publish to MediaMTX. file_stream is the path name.

    • Example 2: Publish a webcam as an RTMP stream:

      bash
      ffmpeg -f v4l2 -i /dev/video0 -c:v libx264 -preset veryfast -c:a aac -f flv rtmp://localhost:1935/live/webcam_stream
      * -f v4l2 -i /dev/video0 : Specifies a Linux webcam as a video source. On other platforms or with other capture devices adjust appropriately.
      * -c:v libx264: Specifies H.264 video encoding.
      * -preset veryfast: Use a fast encoding preset (balance between speed and quality).
      * -c:a aac: Specify AAC audio encoding.
      * -f flv: Specify the output format as FLV (required for RTMP).
      * rtmp://localhost:1935/live/webcam_stream: The RTMP URL to publish to MediaMTX.

    • Example 3: Publish a screen recording:
      “`bash
      # Linux (using x11grab)
      ffmpeg -f x11grab -framerate 30 -video_size 1920×1080 -i :0.0 -c:v libx264 -preset ultrafast -f rtsp rtsp://localhost:8554/screen

      Windows (using gdigrab)

      ffmpeg -f gdigrab -framerate 30 -i desktop -c:v libx264 -preset ultrafast -f rtsp rtsp://localhost:8554/screen

      macOS (using avfoundation)

      ffmpeg -f avfoundation -framerate 30 -i “1:0” -c:v libx264 -preset ultrafast -f rtsp rtsp://localhost:8554/screen
      “`

    These FFmpeg examples demonstrate the flexibility of publishing to MediaMTX. You can adapt these commands to various input sources and encoding settings.

4. Accessing Streams from MediaMTX

Once streams are being published to MediaMTX, you can access them using various client applications and protocols.

  • VLC Media Player (RTSP, RTMP, HLS):

    VLC is a versatile media player that supports various streaming protocols.

    1. Open Network Stream: In VLC, go to Media -> Open Network Stream... (or press Ctrl+N).
    2. Enter the URL:
      • RTSP: rtsp://[mediamtx_ip_address]:8554/[path_name]
        Example: rtsp://192.168.1.50:8554/camera1 (if you named your path camera1)
      • RTMP: rtmp://[mediamtx_ip_address]:1935/live/[path_name]
        Example: rtmp://192.168.1.50:1935/live/obs_stream
      • HLS: http://[mediamtx_ip_address]:8888/[path_name]/index.m3u8
        Example: http://192.168.1.50:8888/camera1/index.m3u8
    3. Click Play: VLC should connect to the stream and start playing.

  • FFplay (RTSP, RTMP, HLS):

    FFplay is a simple media player that comes with FFmpeg.

    • RTSP: ffplay rtsp://[mediamtx_ip_address]:8554/[path_name]
    • RTMP: ffplay rtmp://[mediamtx_ip_address]:1935/live/[path_name]
    • HLS: ffplay http://[mediamtx_ip_address]:8888/[path_name]/index.m3u8

  • Web Browsers (HLS, WebRTC):

    • HLS: Most modern web browsers support HLS playback natively. Simply enter the HLS URL (e.g., http://[mediamtx_ip_address]:8888/[path_name]/index.m3u8) into the browser’s address bar.
    • WebRTC: MediaMTX includes a simple web page for WebRTC playback. Access it through:
      http://[mediamtx_ip_address]:8889/[path_name]
      You’ll need to enable WebRTC in your mediamtx.yml file.

  • Other Clients: Many other applications and devices support RTSP, RTMP, or HLS, including:

    • Security camera viewing software (e.g., Blue Iris, iSpy).
    • Mobile apps (e.g., VLC for Android/iOS, IP Cam Viewer).
    • Smart TVs and streaming devices.

5. Advanced Configuration and Features

MediaMTX offers a wealth of configuration options to tailor its behavior to your specific needs. Here are some of the key advanced features:

  • Authentication:

    Protecting your streams with authentication is crucial for security. MediaMTX supports both basic and digest authentication for RTSP.

    yaml
    rtsp:
    authentication: yes
    user: myuser # Replace with your desired username
    pass: mypassword # Replace with your desired password
    When authentication is enabled, clients will need to provide the username and password to access the streams. Use strong, unique passwords.

  • Encryption (RTSPS):

    For even greater security, you can enable RTSPS (RTSP over TLS/SSL), which encrypts the communication between the server and clients.

    yaml
    rtsp:
    encryption: yes
    serverKey: /path/to/your/server.key # Path to your server's private key
    serverCert: /path/to/your/server.crt # Path to your server's certificate
    You’ll need to generate a TLS certificate and private key. You can use Let’s Encrypt for a free certificate, or create a self-signed certificate for testing.

  • Multicast:

Multicast is useful for efficiently distributing a single stream to multiple clients on the same network. With multicast, the server sends the stream data only once, and the network devices (switches and routers) handle replicating the data to the subscribed clients. This significantly reduces bandwidth usage compared to unicast, where the server sends a separate stream to each client.

```yaml
rtsp:
  protocols: [multicast]
paths:
    multicast_stream:
      source: publisher
      sourceOnDemand: yes
      multicastIP: 239.0.0.1  # Choose a multicast IP address
      multicastRTPPort: 8000    # Multicast port for RTP
      multicastRTCPPort: 8001   # Multicast port for RTCP

```
Client-side configuration for multicast involves specifying the multicast address and port. In VLC for example: `rtsp://239.0.0.1:8000`

  • runOnReady, runOnNotReady, runOnDemand:

    These powerful directives allow you to execute shell commands or scripts when a stream becomes ready, becomes not ready, or when a client requests an on-demand stream. This enables automation and integration with other systems.

    yaml
    paths:
    camera1:
    source: rtsp://...
    sourceOnDemand: yes
    runOnReady: |
    # This script is executed when the stream becomes ready (source is available)
    echo "Camera 1 is online!"
    # You could start recording here, send a notification, etc.
    runOnNotReady: |
    # This script is executed when the stream becomes not ready (source is unavailable)
    echo "Camera 1 is offline!"
    # You could send an alert, try to restart the camera, etc.
    runOnDemand: | # This script is executed *only* when a client requests to view an on-demand stream.
    echo "Camera 1 requested by client!"

  • Proxying Multiple Streams:

One of MediaMTX’s key strengths is its ability to act as an RTSP proxy. This allows you to combine multiple camera streams into a single point of access.

```yaml
paths:
  camera1:
    source: rtsp://...
    sourceOnDemand: yes
  camera2:
    source: rtsp://...
    sourceOnDemand: yes
  camera3:
    source: rtsp://...
    sourceOnDemand: yes
```

You can then access each camera stream individually:
*   `rtsp://[mediamtx_ip_address]:8554/camera1`
*   `rtsp://[mediamtx_ip_address]:8554/camera2`
*   `rtsp://[mediamtx_ip_address]:8554/camera3`

  • HLS Configuration:
    If you enable the HLS server, you can customize its behavior:
    yaml
    hls:
    enabled: yes
    variant: lowLatency # or normal. Low latency reduces the segment and part duration, but reduces compatibility with older players.
    segmentCount: 5 #Number of HLS segments to keep on disk
    segmentDuration: 2s # Duration of each HLS segment.
    partDuration: 200ms # Duration of each Low-Latency HLS part
    segmentMaxSize: 50MB # Maximum size of each segment.

  • WebRTC Configuration:
    yaml
    webrtc:
    enabled: yes
    candidates:
    - 192.168.1.1 #The public IP of your server, if you have one.
    # You can configure ICE servers for NAT traversal here.
    # Example using Google's public STUN server:
    iceServers:
    - urls: ["stun:stun.l.google.com:19302"]

  • API and Web UI:

    MediaMTX provides a REST API and a web interface for managing the server.

    • Web UI: Access the web UI by navigating to http://[mediamtx_ip_address]:9997 in your web browser. The web UI provides a user-friendly interface for monitoring streams, viewing logs, and managing configurations. The web UI is disabled by default. To enable it, you must set a username and password:
      yaml
      api:
      readTimeout: 10s
      writeTimeout: 10s
      username: myusername # Replace with your desired username
      password: mypassword # Replace with a strong password
    • REST API: The API allows you to interact with MediaMTX programmatically. You can use tools like curl or programming languages like Python to query the server status, add/remove paths, and control other aspects of the server. The API documentation is available on the MediaMTX GitHub page and can also be accessed via the Swagger UI at http://[mediamtx_ip_address]:9997/swagger/.

  • SRT Configuration:

Secure Reliable Transport (SRT) provides low-latency, reliable streaming over unreliable networks. MediaMTX supports both caller and listener modes for SRT.
“`yaml
paths:
srt_stream:
source: srt://localhost:9000?mode=caller # Example for SRT caller mode
sourceOnDemand: yes
# OR
srt_stream_listener:
source: srt://localhost:9000?mode=listener&latency=20 # Example for SRT listener mode. latency is in ms.
sourceOnDemand: yes

```
  • Caller Mode: The source (e.g., FFmpeg) initiates the connection to MediaMTX.
  • Listener Mode: MediaMTX waits for an incoming connection from the source.
  • Latency: The latency parameter controls the buffering time to compensate for network jitter.

6. Troubleshooting

This section addresses common problems and their solutions.

  • No Stream Output:

    • Check the RTSP URL: The most frequent issue is an incorrect RTSP URL. Double-check the URL with your camera’s documentation, and ensure the username, password, IP address, and path are correct.
    • Firewall Issues: Make sure your firewall (on the MediaMTX server and any network firewalls) allows traffic on the necessary ports (8554 for RTSP, 1935 for RTMP, 8888 for HLS, 8889 for WebRTC, and any custom ports you’ve configured).
    • Network Connectivity: Verify that the MediaMTX server can reach the IP camera or other source device. Use ping to test basic connectivity.
    • sourceOnDemand: If you’re using sourceOnDemand: yes, ensure that a client is actually trying to connect to the stream. The source won’t be activated until a client requests it.
    • MediaMTX Logs: Examine the MediaMTX logs (in the console or log file) for any error messages. Increase the logLevel to debug for more detailed information.
    • Camera Settings: Some cameras have settings that can interfere with streaming, such as requiring authentication, having specific codec settings, or being blocked by their own internal firewall.

  • Stream Lag or Buffering:

    • Network Congestion: High network traffic can cause buffering. Check your network usage and consider using a wired connection instead of Wi-Fi if possible.
    • Insufficient Bandwidth: Ensure your network has enough bandwidth to handle the stream’s bitrate. High-resolution, high-framerate streams require more bandwidth.
    • Encoding Settings: If you’re using FFmpeg or OBS Studio to publish the stream, try reducing the bitrate or using a faster encoding preset (e.g., veryfast or ultrafast in FFmpeg).
    • HLS Segment Duration: For HLS, try reducing the segmentDuration (but not too low, as this can impact compatibility).
    • Client Buffer: Some clients have their own buffering settings. Check the client application’s settings to see if you can adjust the buffer size.
    • readTimeout and writeTimeout: If these are too low for your network they can induce lag. If they are too high then long pauses may occur when network connectivity is poor.

  • VLC Connection Issues:

    • RTSP over UDP: VLC sometimes defaults to UDP for RTSP, which can be unreliable. Try forcing TCP:
      • In VLC, go to Tools -> Preferences -> Input / Codecs.
      • Under Network, change Live555 stream transport to RTP over RTSP (TCP).
    • Firewall (again): VLC can sometimes be blocked by firewalls even if other applications work.

  • WebRTC Not Working:

    • HTTPS: WebRTC often requires HTTPS for secure connections, especially in modern browsers. You might need to set up a reverse proxy (like Nginx or Caddy) with a valid TLS certificate to handle HTTPS for MediaMTX’s WebRTC endpoint.
    • ICE Servers: Properly configured ICE servers (STUN and TURN) are essential for WebRTC to work through NATs and firewalls. Make sure you have at least a STUN server configured in mediamtx.yml. For more complex network setups, you’ll likely need a TURN server.
    • Browser Permissions: Ensure you have given the browser necessary permissions to access your microphone and webcam.

  • FFmpeg Errors:

    • Incorrect Input: Double-check the input source for FFmpeg (e.g., /dev/video0 for a webcam, input.mp4 for a file).
    • Codec Issues: Ensure the codecs you’re using are supported by both FFmpeg and MediaMTX. H.264 video and AAC audio are generally good choices.
    • Missing Libraries: If FFmpeg reports missing libraries, you might need to install additional packages for your distribution (e.g., libx264-dev, libfdk-aac-dev).
    • Permissions (Linux): When accessing devices like webcams, ensure the user running FFmpeg has the necessary permissions.

  • Docker-Specific Issues:

    • Port Mapping: Double-check that you’ve correctly mapped the ports using the -p flag in your docker run command.
    • Volume Mounting: If you’re using a persistent configuration, make sure you’ve mounted the mediamtx.yml file correctly using the -v flag.
    • Network Mode: For some advanced setups (like multicast), you might need to use a different Docker network mode (e.g., host mode).

7. Security Best Practices

  • Use Strong Passwords: Always use strong, unique passwords for MediaMTX authentication and for any devices (like IP cameras) that you’re connecting to it.
  • Enable Authentication: Never expose your streams publicly without authentication.
  • Use Encryption (RTSPS): Encrypt your RTSP streams with TLS/SSL to protect them from eavesdropping.
  • Firewall: Use a firewall to restrict access to the MediaMTX server to only authorized IP addresses or networks.
  • Keep Software Updated: Regularly update MediaMTX and your IP cameras to the latest versions to patch security vulnerabilities.
  • Isolate Network: Consider placing your IP cameras and MediaMTX server on a separate VLAN (Virtual LAN) to isolate them from your main network. This enhances security and prevents potential compromise of your primary network.
  • Limit Access: Only grant access to the streams to the users and devices that need it.
  • Use a VPN: If accessing the streams remotely, use a VPN (Virtual Private Network).
  • Monitor Logs: Regularly check the MediaMTX logs for any suspicious activity.
  • Disable Unused Features: Disable any protocols or features that you’re not using (e.g., RTMP, HLS if you only need RTSP). This reduces the attack surface.
  • Reverse Proxy: Use a reverse proxy (like Nginx or Caddy) in front of MediaMTX to handle TLS termination, load balancing, and other security features. This also helps to obscure the internal workings of your MediaMTX setup.
