What is FTC Stream Scorer?

FTC Stream Scorer is a free, open-source scoring application designed specifically for FIRST Tech Challenge (FTC) competitions. It provides a professional-grade scoring system that teams can use during practice matches, scrimmages, or live streams.

The software features a dual-window system: a Control Panel for easy scoring input and a Stream Output window that can be captured by streaming software like OBS for professional-looking broadcasts.

Webcam Compatibility

FTC Stream Scorer works with any webcam that your computer recognizes, including:

  • Physical webcams - Any USB or built-in webcam
  • Virtual webcams - Software-based webcam sources
  • DroidCam - Use your phone as a webcam
  • ManyCam - Virtual webcam with video mixing
  • Other virtual webcam software - Any software that creates a virtual webcam device

Note: OBS Virtual Camera is not currently supported. If you need to use pre-recorded footage or OBS sources, we recommend using ManyCam as a bridge (see ManyCam Setup section below).

ManyCam Setup for Virtual Webcam

ManyCam is a free virtual webcam software that allows you to add the FTC Stream Scorer overlay to pre-existing footage, video files, or other video sources. This is perfect for post-production scoring or when you want to overlay scores on recorded match footage.

Getting Started with ManyCam

  1. Download ManyCam - Visit manycam.com/download and install the free version
  2. Add your video source - In ManyCam, click the "+" button to add a video source:
    • Select "Video File" for pre-recorded footage
    • Select "YouTube URL" for online videos
    • Select "Screen" to capture your desktop
  3. Enable ManyCam Virtual Webcam - ManyCam automatically creates a virtual webcam device on your system
  4. Launch FTC Stream Scorer - Open the application
  5. Select ManyCam as your webcam - In the FTC Stream Scorer Control Panel, select "ManyCam Virtual Webcam" from the webcam dropdown
  6. Start scoring! - The scoring overlay will now appear on top of your ManyCam video source

Tip: This setup is great for reviewing and scoring practice matches after they've been recorded, or for adding professional overlays to existing FTC match footage.

Windows Defender Notice

Important: It is likely that Windows Defender will alert you that this application is a virus or potentially unwanted software.

This is a false positive. This occurs because we have not signed the software package. Code signing certificates cost hundreds of dollars per year, which is not feasible for a free, open-source project.

Install the software at your own discretion. To bypass Windows Defender, click "More info", then click "Run anyway".
