YouTube and Hetzner do not guarantee uninterrupted uptime, so plan to monitor the stream and test recovery before relying on it.
What you need before you start
- A Hetzner Cloud server with an internet-reachable public network interface and enough CPU, memory, and outbound traffic allowance for your stream.
- A compatible video file stored on the VPS or otherwise available to it. This method loops a file; it does not stream live camera input.
- A YouTube channel eligible to create a live broadcast, plus the matching YouTube ingest URL and stream key.
- FFmpeg installed on the server, SSH access, and a plan for process supervision, monitoring, and recovery.
Check YouTube’s current live encoder settings and live streaming setup guidance before configuring the encoder. The steps and command below are an implementation pattern, not a tested, universally working recipe for every FFmpeg build, input file, or account.
Choose the stream settings
Match resolution and bitrate
YouTube’s current H.264 guidance recommends 10 Mbps for 1080p at 30 fps and 4 Mbps for 240p–720p at 30 fps. These are YouTube recommendations, not a guarantee that a particular server or source will remain stable. Choose a resolution and frame rate your source can support, then check that the VPS can sustain the required outbound traffic.
For a straightforward SDR stream, 720p30 or 1080p30, constant bitrate (CBR), AAC audio, and a two-second keyframe interval are sensible starting points. Do not apply one bitrate to every resolution, frame rate, or codec. YouTube documents H.264, H.265, and AV1 video, AAC or MP3 audio, and up to 60 fps; available combinations and appropriate bitrates depend on the chosen format.

Use RTMPS and a two-second keyframe interval
YouTube recommends RTMPS, the secure extension of RTMP, and recommends a keyframe every two seconds, with four seconds as the maximum recommended interval. RTMPS protects the encoder-to-ingest connection in transit; it does not make a publicly exposed stream key safe.
Create the YouTube broadcast and protect its stream key
- Open YouTube Live Control Room and create or select the intended broadcast. You can also create a broadcast through YouTube’s Live Streaming API; API configuration includes ingestion type and stream URL fields.
- Copy the ingest URL and stream key associated with that broadcast. Use the exact values YouTube displays—do not substitute a generic endpoint or a key from another broadcast.
- Keep the stream key secret. Treat it as a publishing credential: do not put it in source control, share it, or expose it in a public log. Store it in a restricted configuration file or another protected secret store. Regenerate it if it is exposed.
- After connecting FFmpeg, check the broadcast preview and YouTube’s stream-health diagnostics before making the broadcast public.
Prepare the Hetzner VPS
Check network access and firewall policy
The VPS needs outbound internet connectivity to reach YouTube’s ingest service. Hetzner’s Cloud server overview explains server networking and public Primary IP options. If you have restricted egress with a Cloud Firewall, confirm its rules allow the needed outgoing connection.

Check traffic allowance and estimate egress
Outbound video to YouTube counts as traffic from Hetzner. Hetzner’s Cloud traffic documentation lists 20 TB of included monthly traffic for EU CX, CPX, and CAX Cloud Servers; allowances vary by product and region, including in the US and Singapore. The documentation says excess traffic is charged in 100 MB blocks. Check the current allowance and overage terms for your exact account, plan, and server location before choosing a bitrate.
Estimate data use by multiplying the stream’s total bitrate by the number of broadcast hours, then allow for protocol overhead, retries, audio, software updates, and other server traffic. As arithmetic, a continuous 1 Mbps stream for 30 days is about 324 GB in decimal units before overhead; actual usage depends on the bitrate and runtime.

Understand the network and CPU limits
Hetzner says Cloud bandwidth is not guaranteed; its FAQ says customers can expect about 300–500 Mbit/s while Cloud instances share the host’s 10 Gbit connection. Treat that as expected host networking, not a per-instance speed guarantee. Hetzner distinguishes shared-resource from dedicated-resource plans; if you transcode under heavy CPU load, check the plan’s resource model and measure CPU and network behavior on the actual server.
Install FFmpeg and run a looping stream
Install FFmpeg using the package manager for your VPS operating system, then verify that the installed build includes the input and output support you need. Put the source file in a stable location, such as /srv/stream/video.mp4, and make sure the account that runs FFmpeg can read it.

Keep the real key out of shell history and visible logs; the example uses a literal URL only to show where the endpoint goes, not to recommend storing credentials in a script. The command is not verified for every FFmpeg build or input. Test the source file, output settings, and reconnect behavior on your actual server. A file with incompatible codecs, damaged timestamps, or an unexpected audio layout may need different input or encoding options.

Run it as a supervised service
Do not rely on an interactive SSH session to keep FFmpeg alive. Run it as a dedicated unprivileged user under a process supervisor such as systemd, configured to restart the process on failure. Restrict access to the service configuration and any file containing the stream key. A supervisor can restart a process; it cannot repair a missing source file, exhausted traffic allowance, invalid key, or YouTube-side issue.
There is no universal systemd unit or seamless reconnect behavior established for this setup. Choose restart behavior for your particular command, then test what happens when the input disappears, the network drops, FFmpeg exits, and the server reboots.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Verify the stream and keep it healthy
- Start FFmpeg and check its service status and logs for input, encoding, and connection errors.
- In YouTube Live Control Room, confirm that the preview appears and review stream-health diagnostics. Resolve warnings before making the broadcast public.
- Observe CPU, memory, network throughput, source-file availability, and egress usage. A process that is running does not by itself prove that YouTube is receiving a healthy stream.
- Test recovery by stopping FFmpeg, interrupting its network access, and restarting the VPS during a controlled session. Confirm what the supervisor does and whether YouTube resumes receiving the stream.
- Recheck the broadcast and logs after any change to the media, FFmpeg build, server plan, firewall, or stream key.
Troubleshooting common failures
| Symptom | Likely cause | What to check or do |
|---|---|---|
| YouTube shows no incoming stream | Wrong ingest URL or stream key, blocked outbound connection, or FFmpeg output failure. | Compare the endpoint and key with the selected broadcast, check FFmpeg logs and egress firewall rules, then reconnect and inspect the preview. |
| Stream health is poor or unstable | Bitrate exceeds stable outbound capacity, encoding load is too high, or the source and output settings do not match well. | Check CPU and network behavior on the VPS, reduce resolution or bitrate if needed, use CBR, and keep the keyframe interval within YouTube’s guidance. |
| FFmpeg exits when the SSH session ends | The process was launched in the interactive session rather than a supervisor. | Run it under systemd or another process supervisor, and check the service status and logs after disconnecting. |
| FFmpeg restarts but the stream does not recover | The source is unavailable, the key or endpoint is invalid, or the connection failure requires different handling. | Inspect the restart logs and YouTube stream health; test the recovery path on the actual media and server rather than assuming restart guarantees reconnection. |
| Traffic use or charges are higher than expected | Continuous outbound bitrate, retries, other server traffic, or a plan/location allowance smaller than assumed. | Compare measured traffic with the exact Hetzner plan’s current regional allowance and overage terms. |
Rights and YouTube policy still apply
A VPS and an RTMPS connection do not give you rights to broadcast the video, music, artwork, or other material in the stream. Confirm that you have the necessary rights and review YouTube’s current rules for the content and monetization approach you plan to use. Whether a particular channel or continuous stream meets YouTube’s eligibility and policy requirements depends on its circumstances.
Or let it run in the cloud
If you would rather not operate a VPS, FFmpeg process, supervisor, and recovery checks, StreamNeo is a cloud service for keeping a YouTube channel live from uploaded videos. Upload a recording or build a playlist, add your YouTube stream key, and go live. It loops the uploaded video from the cloud; it does not stream from a camera or to other platforms.
- Nothing needs to stay on at home; the stream runs from the cloud.
- Any quality up to 4K 60fps at one flat price per slot, with no re-encode or quality tiers.
- Automatic recovery if YouTube drops the stream.
- The first day is free, with no card required.
Monthly: $9.99 per month. For this setup, StreamNeo is the managed alternative to a self-managed VPS; the VPS gives you control over the server and FFmpeg, while StreamNeo avoids keeping that streaming process running on your own infrastructure. Start the free day on StreamNeo.
