Running OBS Studio on a Raspberry Pi 5 for Live-Streaming Maker Builds

This site has a guide on turning a Pi camera into a UVC webcam or NDI source, and a separate one on product photography for sellers — but neither covers actually running a live broadcast production tool on the Pi itself. If you want to stream a CNC cut, a resin print finishing, or a soldering session to Twitch or YouTube without tying up your main desktop, or you want a dedicated low-power streaming box bolted to a shop camera, OBS Studio now runs natively and usably on a Raspberry Pi 5 — something that was painfully marginal on earlier Pi hardware.

Why the Pi 5 Specifically

OBS Studio is a genuinely heavy application: it's compositing multiple video sources, running scene transitions, and encoding video in real time, all at once. The Pi 5's faster CPU and, critically, its hardware video encode block make this workable where a Pi 4 struggled — software x264 encoding on a Pi 4 would frequently drop frames or max out the CPU with just one camera source. The Pi 5 can lean on hardware-accelerated H.264 encoding, which keeps CPU headroom free for OBS's own compositing and scene work.

Installation

OBS doesn't ship an official pre-built ARM64 package for Raspberry Pi OS the way it does for x86 Linux, so the realistic paths are:

• Build from source against Raspberry Pi OS (64-bit) or Ubuntu Server (ARM64): OBS's own build instructions work on aarch64 Linux with the right dependencies (Qt6, FFmpeg, libobs) installed first. Expect this to take a meaningful chunk of time on Pi-class hardware — plan for 30–60+ minutes of compile time depending on your Pi 5's RAM and whether you're building with all plugins.
• Use a community-maintained ARM64 build or Flatpak, where available — check current availability, since ARM Linux Flatpak support for OBS has improved over time but isn't guaranteed to include every plugin you'd get from source.

Either way, use the 64-bit version of Raspberry Pi OS (or a 64-bit Ubuntu Server image) — the 32-bit OS will not give you usable performance for this workload, and some dependencies won't build at all against it.

Capture Sources That Actually Work Well

SourceNotes Raspberry Pi Camera Module (via libcamera)Best native option; feed it into OBS through a V4L2 loopback device created from the libcamera pipeline, since OBS expects a standard V4L2 capture device USB webcamWorks directly as a V4L2 source with no extra setup — the simplest path if you already have a USB camera HDMI capture dongle (from a separate camera or your CNC/laser controller's screen)Cheap USB HDMI-to-UVC capture sticks work as a standard V4L2 source, letting you stream a controller's own display alongside a camera feed Browser source / overlay graphicsWorks but adds real CPU load — keep overlays simple on Pi hardware, this isn't the place for heavy animated browser-based overlays

Encoding Settings That Keep It Stable

Set OBS to use the Pi 5's hardware H.264 encoder (exposed through V4L2 M2M or VA-API depending on your build) rather than the software x264 encoder — this is the single biggest factor in whether streaming stays smooth. Keep your output resolution and framerate realistic for the hardware: 1080p30 is a comfortable target for a well-built Pi 5 setup; 1080p60 or multi-source scenes with picture-in-picture compositing will push you closer to the edge of what's comfortable. Test a local recording first, watch CPU and temperature with a tool like htop and vcgencmd measure_temp running alongside, and back off resolution or framerate if you see thermal throttling or dropped frames before committing to a live broadcast.

Keeping It Running Unattended

For a semi-permanent shop streaming setup, run the Pi headless and start OBS automatically on boot into a streaming scene via a systemd service or a simple autostart script, rather than needing a monitor and keyboard attached every time. Active cooling (a case fan or the official active cooler) is worth having for sustained streaming sessions — this workload runs the CPU far harder and for much longer than typical Pi server tasks like Pi-hole or Home Assistant.

A Note on Realistic Expectations

A Pi 5 running OBS is a genuinely usable single-camera streaming box for shop content — it is not a replacement for a proper desktop streaming rig if you need multiple high-resolution camera sources, heavy scene compositing, or game-capture-style workloads. Know that boundary going in and you'll get a reliable result; push well past it and you'll spend your time fighting dropped frames instead of streaming.

Paired with the camera-to-NDI guide already on this site, this gives you two complementary options: NDI if you're feeding a separate streaming PC on your network, and a self-contained OBS box on the Pi itself if you want one less piece of hardware in the chain.
