Live Streamr setup for community-driven streaming.

Inspired by other Ultimate livestream producers — and a wish for reliable live scores — I built and tested this setup as a practical way to share more of the game. It is a shareable framework, not a private or final system. You are welcome to borrow all of it, or only the parts that help your event.

An example field kit is a Sony a5100 camera, a Blackmagic Web Presenter HD and the necessary cables. On-site internet can come from ethernet or a phone connected through USB-C tethering. The aim is to share practical experience and improve the setup together.

Too much for one person

Filming, monitoring audio, managing overlays, keeping score and troubleshooting compete for the same person’s attention.

Missing graphics

Without a score and team names on screen, viewers lose important match context.

Remote commentary is awkward

Commentators need a practical way to contribute without being physically beside the camera or production computer.

Production runs in OBS Studio on a Linux VPS. I have tested this on Hetzner, but other providers are possible. The field crew handles video capture and internet; graphics, scenes, monitoring and the final output are handled remotely.

Reuse the OBS project between events by reconnecting sources and updating event graphics. The production structure can stay familiar even when the venue or field team changes.

Connect the camera to the Blackmagic Web Presenter HD through HDMI / SDI. The hardware encoder uses ethernet or USB-C phone tethering to reach the internet, then sends SRT video to remote OBS on the VPS. An internet connection is required on-site.

Choose the capture approach that fits the crew

Blackmagic

Dedicated hardware encoding with the Blackmagic Web Presenter HD.

Larix

A lightweight workflow using a phone as the camera and encoder.

VDO Ninja

Browser-based remote contributions and ad hoc audio or video.

A commentator can join from a phone or laptop anywhere with internet. Share a VDO Ninja invite link: it runs in the browser, with no install needed. Bring the contribution into OBS on the VPS through a Browser Source / audio input and include it in the final program audio mix.

A microphone, headphones and decent internet let volunteers contribute from home or the venue. The remote OBS operator controls the audio mix.

The scorekeeper uses Upsi without needing OBS access. Upsi sends goals, points and match-state changes to the PointTracker API — the single source of match state. Writes are protected with a claim code; reads are open for viewers and overlays.

The overlay reads the API and renders the current score. OBS only displays that webpage — it does not manage the match state.

Why keep scoring separate?

• No scene editing on each point; the score updates automatically.
• The same match data can be reused across overlays.
• A phone scorekeeper stays separate from stream production.
• The setup can be reused between matches and events.

Here is how the pieces fit together for one event, with a clear division between camera, scoring, commentary and production.

The field kit may use a Sony a5100 or another camera, a Blackmagic or another encoder, and ethernet or USB-C internet. Remotely, the OBS operator uses the VPS, the PointTracker backend, a Browser Source score overlay and VDO Ninja commentary to build the final YouTube program.

1. Connect the camera

   Camera into the Blackmagic Web Presenter HD, or another suitable encoder.

2. Send the video

   The encoder sends SRT over the on-site internet connection to remote OBS.

3. Keep score in Upsi

   The scorekeeper updates the match from the sideline, without OBS access.

4. Update PointTracker

   Upsi sends the match state to the PointTracker backend.

5. Read the live API

   The browser overlay reads current match data from PointTracker.

6. Layer the score

   OBS displays the overlay webpage on top of the incoming video.

7. Bring in commentary

   The commentator joins through VDO Ninja; the OBS operator controls the mix.

8. Publish the program

   OBS sends the final video, graphics and audio to YouTube.

This is not a single perfect solution. Borrow the setup or the parts that suit your event, share what works in practice and contribute improvements. Better community streams can grow from small, useful changes made together.

Both the PointTracker backend and the Upsi app are open source.
