Start the printer feed
From the Bambu Studio video panel, open Camera Setting and toggle Go Live for the selected printer.
Watch the printer live when a print run is active.
Bambu Studio's Go Live feed can be relayed straight into Cloudflare Stream. This page is the public viewing page, so when the relay is publishing the print feed appears here automatically without asking visitors to install anything.

Current constraint

Live feed
The stream panel stays simple: live when a public broadcast exists, clean placeholder when it does not.
The raw Bambu virtual camera is local only. This page is set up around one Cloudflare live input so the site can switch to the live print automatically when the local relay sees Bambu Go Live.
Cloudflare live input needed.
The page is ready to show the live print, but it still needs the fixed Cloudflare Stream customer code and live input ID for the built-in player.
This page is designed to use Cloudflare Stream as the primary public player. If you want YouTube later, the clean path is to add it as a Cloudflare simulcast output instead of changing the viewer page.
Workflow
The stream path is built around what Bambu Studio actually exposes.
The local relay detects the Bambu source
Bambu's virtual camera tool exposes the feed locally through ffmpeg.sdp. A local relay watches for that feed and publishes it to the fixed Cloudflare live input.
The website shows the public output
Cloudflare Stream handles playback on the site. If you want YouTube later, Cloudflare can simulcast the same live input there without changing the Bambu side.
Only one virtual camera stream at a time.
If you switch printers and start another stream, the first Bambu virtual camera stream stops. The page is intentionally designed around that one-live-feed behavior.
The operator path stays separate from the viewer page.
Closing Bambu Studio does not stop the virtual camera tool by itself, and the relay plus Cloudflare player are independent of the website layout. OBS is optional, not required, unless you want overlays or manual production control.
Operator notes
The public page stays clean, but the setup details are here when you need them.
How do I start the Bambu Studio camera stream?
Select the printer, open the Camera Setting icon in the video panel, and toggle Go Live. Bambu Studio only supports one virtual camera stream at a time. With the local relay watcher running, that is enough to publish the feed to the site.
Do I need OBS for the website stream?
No. The default setup is Bambu Go Live into the local relay and then into Cloudflare Stream. Use OBS only if you want overlays, scene switching, or a manual production workflow.
If I do want OBS later, how do I add the Bambu feed?
Use a Media Source in OBS, uncheck Local File, and point the input to the Bambu Studio ffmpeg.sdp file URL. Then set the FFmpeg options exactly as shown below.
Input:
file:C:/Users/[username]/AppData/Roaming/BambuStudio/cameratools/ffmpeg.sdp
FFmpeg options:
protocol_whitelist=file,udp,rtp
What is the cleanest way to make this page go live publicly?
Use one fixed Cloudflare Stream live input for the site. That keeps the viewer page stable, lets the page detect whether the input is live, and makes YouTube later a Cloudflare-side simulcast instead of a separate local workflow.
Ask about a print, a live run, or a custom setup.
Use this when you want to ask about a live print session, a print-related question, or the stream setup itself.
- What you want printed or shown live
- Whether the question is about the print or the stream
- Any timing details that matter
