📽️ A chatGPT prompt & response explaining how to use OBS software to read in an RTSP stream as a virtual camera device.

You:

I want to use OBS (Open Broadcaster Software) to create a virtual webcam device that receives realtime video from an RTSP stream on port 554. How do I go about doing this? Give a guide that includes information about both Mac & Windows steps -- that is, to add (mac only) and (windows only) sections in the guide, not provide separate guides for each OS.


ChatGPT:

To use OBS (Open Broadcaster Software) to create a virtual webcam device that receives real-time video from an RTSP stream on port 554, follow these steps. I have included specific steps for both macOS and Windows.

1. Install OBS Studio

  • (Mac & Windows) Download and install OBS Studio from the official OBS website. Ensure you select the version appropriate for your operating system.

2. Install OBS-VirtualCam (Windows Only)

  • (Windows Only) For Windows, you need to install the OBS-VirtualCam plugin. Download it from the OBS Project forum. Run the installer and follow the instructions to integrate it with OBS.

3. Set Up RTSP Stream Source in OBS

  • (Mac & Windows) Open OBS and create a new scene by clicking the "+" under the "Scenes" box.
  • Click the "+" button under the "Sources" box and select "Media Source." Click "OK."
  • Uncheck "Local File" and enter your RTSP stream URL in the "Input" field. Example: rtsp://username:password@IP_address:554/stream
  • Check "Use hardware decoding when available" for better performance and click "OK."

4. Start Virtual Camera

  • (Mac Only) As of recent updates, OBS on macOS includes built-in support for a virtual camera. After setting up your scene:
    • Go to "Tools" in the menu bar.
    • Select "Start Virtual Camera."
  • (Windows Only) After setting up your scene:
    • Click on "Start Virtual Camera" at the bottom right of the OBS interface under "Controls."

5. Use Virtual Camera in Other Applications

  • (Mac & Windows) Open any application where you want to use the virtual webcam (e.g., Zoom, Skype).
  • Go to the video settings of the application and select "OBS Virtual Camera" as the camera source.

6. Troubleshooting

  • (Mac & Windows) If the stream does not appear, ensure that your firewall is configured to allow traffic through port 554 and that OBS is allowed through your firewall.
  • (Mac & Windows) Double-check the RTSP URL and credentials for accuracy.

Important Note: Before performing these steps, ensure you have the proper permissions to access and distribute the video from the RTSP stream. If you encounter any issues that seem network-related, verify your network settings or contact your network administrator.

This setup allows you to bring an RTSP stream into OBS and use it as a virtual webcam across various applications. If there are any specific issues during the setup or if the virtual camera does not appear in other applications, we may need to gather more details to proceed to the next step.
