This can restart the local encoder; it cannot guarantee YouTube will keep one live event open indefinitely. Use the RTMPS URL and protected stream key from YouTube Live Control Room, and monitor both the service and the live event.
What systemd can—and cannot—keep running
A systemd service can start your encoder when the server boots and retry it after a failure. The relevant settings are Restart=on-failure and RestartSec=. Automatic attempts are subject to systemd start-rate limits, and restarting FFmpeg does not repair a bad stream key, broken input, unavailable network, or failed host.
There are two separate goals: keeping the encoder process alive and keeping a YouTube live event available to viewers. YouTube says encoder streams under 12 hours are automatically archived; that is an archive behavior, not a promise of an indefinitely open event. Plan the event workflow separately and verify it in Live Control Room.
Prepare the YouTube stream and encoding settings
Copy the RTMPS address and protect the key
In YouTube Live Control Room, copy the stream URL and stream key into your encoder configuration. Prefer the RTMPS URL: YouTube recommends RTMPS, an encrypted extension of RTMP, and notes that the control room may show an RTMP address by default. Follow YouTube’s instructions there to reveal the RTMPS address. YouTube describes stream keys as “like your YouTube stream’s password and address.” Keep the key out of publicly readable scripts, logs, and shell-history commands. If it is exposed, reset it in YouTube and update the encoder. YouTube: Manage live stream settings

Choose settings for your resolution and frame rate
YouTube’s current encoder guidance lists RTMP/RTMPS ingest; H.264, H.265, and AV1 video; frame rates up to 60 fps; constant bitrate (CBR); and a recommended two-second keyframe interval that should not exceed four seconds. Its recommended bitrate depends on codec, resolution, and frame rate, so consult the live table for your chosen combination instead of using one universal number. As examples from YouTube’s table, H.264 at 1080p/30 fps is listed at 10 Mbps recommended, while H.264 at 720p/30 fps is listed at 6 Mbps recommended. These are encoder recommendations, not measurements of your server’s available upload capacity. YouTube recommends AAC or MP3 audio and lists further audio settings. YouTube encoder settings
- Match the output resolution and frame rate to the media and the event you intend to run.
- Use the bitrate listed by YouTube for that codec and video mode, then verify that the server’s sustained outbound capacity can carry it.
- Check that the installed FFmpeg build supports the selected codec and that the input can be read by the service account.
Create a systemd service for FFmpeg
The unit below is a template, not a tested universal FFmpeg command. Replace the placeholders with your input, supported encoding options, and RTMPS destination. Store credentials in a root-controlled configuration file with restrictive permissions; do not put a real key in a shared unit file or published command. Confirm that your chosen credential mechanism does not expose the key through logs or process inspection. The exact executable path, user, paths, arguments, and shutdown behavior depend on your Ubuntu release, installed FFmpeg build, media, and account setup.

WantedBy=multi-user.targetFor this illustrative unit, create the directories and credential file with appropriate ownership and permissions before starting the service. Check the absolute path to FFmpeg and ensure the stream user can read the media and configuration. The example uses a ten-second retry delay as a starting configuration, not a universally ideal value; choose a delay appropriate to your failure mode and monitoring plan.
Reload, enable, start, and inspect the service
- Create the unit at
/etc/systemd/system/youtube-stream.serviceand adapt its paths, user, credentials, and FFmpeg arguments. - Reload systemd’s unit definitions, then enable the service for boot and start it now:
sudo systemctl daemon-reload sudo systemctl enable --now youtube-stream.service - Check whether systemd considers the service active:
systemctl status youtube-stream.service - Inspect recent service output for FFmpeg errors:
journalctl -u youtube-stream.service -n 100 --no-pager - Reboot during a planned test window and verify the service starts again. Also check the YouTube preview and event status; an active local service alone does not prove that viewers are receiving a usable stream.
Ubuntu Noble’s systemd manual documents Restart=on-failure and RestartSec=. That restart policy responds to process failure, not an operator-requested stop, and repeated rapid failures can hit systemd’s start-rate limit. If retries stop, inspect the logs and correct the underlying problem before clearing or adjusting the limit. Ubuntu Noble systemd.service manual

Plan YouTube event duration and handoffs
A continuously running server process does not create a continuous YouTube event by itself. YouTube says encoder streams under 12 hours are automatically archived, but does not thereby promise indefinite single-event duration or specify one universal event-handoff design. Decide whether you need one scheduled event, repeated events, or a presentation that returns viewers to a new event. In Live Control Room, confirm the scheduled stream and the auto-start and auto-stop choices. YouTube documents those as encoder-controlled options when enabled. YouTube: Set up live streaming
Before relying on a 24/7 presentation, test the event workflow you intend to use and check the preview, live status, and archive behavior. The service can keep retrying FFmpeg while the YouTube event itself needs attention or a new event.

Monitor the full stream path
Systemd supervises a local process, not the entire path from media file to viewer. Check each layer independently:
- Service: Is
youtube-stream.serviceactive, and do the journal logs show repeated failures or restarts? - Input and encoding: Can FFmpeg read the source and produce the intended video and audio? Does the service account have access?
- Network: Is the server connected, and can its outbound link sustain the configured stream bitrate?
- YouTube ingest: Does Live Control Room show a preview and the expected connection status for the correct event?
- Viewer-facing event: Is the intended event actually live, and is its schedule or handoff configured as planned?

Troubleshoot common failures
| Symptom | Likely area to check | What to do |
|---|---|---|
| Service fails immediately or repeatedly restarts | Unit syntax, executable path, permissions, input, or FFmpeg arguments | Read systemctl status and the recent journalctl output. Run a controlled test of the adapted FFmpeg command as the service user, without exposing the key. Correct the error before relying on systemd retries. |
| Service is active, but YouTube shows no preview or an error | RTMPS URL, stream key, codec settings, or network path | Re-copy the RTMPS URL and key from the intended event, confirm the selected encoder settings against YouTube’s guidance, and check the server’s connection. Reset and replace a compromised key. |
| Retries stop after rapid failures | systemd start-rate limit | Use the logs to identify why FFmpeg is failing. Fix the cause, then review the service’s retry delay and systemd start-rate settings rather than repeatedly restarting a broken command. |
| FFmpeg runs, but video or audio is unusable | Input readability, chosen codec, bitrate, resolution, frame rate, or audio configuration | Verify the media and output options, then compare the actual combination with YouTube’s current encoder table. Do not assume a running process means a valid stream. |
| Stream drops when the server or network becomes unavailable | Host or connectivity outage | systemd can restart a failed process only when the host and required services are available. Restore the host or network, then verify the encoder and YouTube event separately. |
| Encoder remains up but the event ends or must be replaced | YouTube event/session workflow | Check the event schedule, archive expectations, and auto-start/auto-stop settings in Live Control Room; systemd does not create or hand off YouTube events. |

Frequently Asked Questions
Will systemd restart FFmpeg if I stop the service manually?
No. The example uses Restart=on-failure, which is for failures rather than an operator-requested stop.
Does an active systemd service prove the YouTube stream is live?
No. Confirm the preview and event status in YouTube Live Control Room as well as checking the local service.
