To keep a prerecorded music stream running around the clock, run FFmpeg in the foreground on an always-on Ubuntu machine and let systemd start it at boot and restart it after failures. YouTube Studio supplies the ingest URL and stream key; FFmpeg sends the media to YouTube Live. This setup can recover from some process exits, but it cannot guarantee a healthy connection or bypass YouTube’s copyright checks.
How the setup works
YouTube Studio creates the live stream and provides its ingest URL and stream key. FFmpeg reads and loops a media file, then sends it to YouTube. A systemd service starts FFmpeg when Ubuntu boots and can restart it after an unexpected exit. Keep FFmpeg in the foreground so systemd can track its actual process.
You need an Ubuntu computer or server that stays powered on, a stable internet connection, FFmpeg, and a video or audio source you have the rights to stream. This guide uses a prerecorded video file with audio; if you have audio-only material, create or choose a compatible video container and visual rather than assuming YouTube will accept an audio-only input.
Prepare YouTube Live and your media
Enable live streaming and create the stream
- In YouTube Studio, enable live streaming for your channel and complete any requested verification. YouTube says a channel must be verified and have no live-streaming restrictions in the previous 90 days. First-time enablement can take up to 24 hours. See YouTube’s live-streaming setup guidance.
- Create or schedule a live stream in YouTube Studio using an encoder workflow. Copy the ingest URL and stream key privately; the key is a credential, not a public identifier. YouTube documents RTMP and RTMPS ingest in its encoder stream settings.
- Use the ingest URL and key format YouTube provides for your stream. Do not assume every account or stream uses the same URL or key.
Check rights and the input file
Use music, artwork, and any video for which you have the necessary rights to stream worldwide on YouTube. YouTube scans live streams for third-party material and may replace the picture, interrupt, or terminate a stream. Licensed material can still be interrupted unless the rights holder allowlists the channel. YouTube’s Livestream terms make the creator responsible for the necessary rights, including music licensing rights.

Before building the service, confirm that FFmpeg can read the chosen file and that its video and audio streams are suitable for the intended broadcast. The example below copies the input’s existing codecs without re-encoding; it is appropriate only when the file’s codecs and stream parameters are accepted by YouTube and the input can be played reliably. If not, choose compatible encoding options and test them before relying on an all-day service.
Install FFmpeg and create a service account
Install FFmpeg using the package source for your Ubuntu release. The exact package availability can vary by release and configured repositories; verify the installed binary with ffmpeg -version. Create a dedicated, unprivileged account and a directory for the media, for example:
sudo useradd --system --create-home --home-dir /srv/youtube-music --shell /usr/sbin/nologin stream
sudo install -d -o stream -g stream /srv/youtube-music
Put your test media at /srv/youtube-music/loop.mp4, owned by the service account or otherwise readable by it. The account should have no broader permissions than the job needs.

Store the stream key safely
Use a protected environment file instead of putting the key in a shared script or publishing it in a unit file. Create /etc/youtube-music.env as root and set its contents to:
YOUTUBE_STREAM_KEY=replace_with_your_private_stream_keyThen restrict access to the file:
sudo chown root:root /etc/youtube-music.env
sudo chmod 600 /etc/youtube-music.env
Do not paste a real key into a public log or support post. If it is exposed, reset it in YouTube Studio and update the local configuration.
Create the FFmpeg wrapper and systemd unit
Use a wrapper so the key reaches FFmpeg safely
Systemd does not run ExecStart= through a shell, so shell-style variable expansion in the command line is not a safe way to interpolate the key. Create an executable wrapper that reads the environment variable and replaces itself with FFmpeg:

This example assumes the standard RTMP ingest base URL shown; prefer the exact ingest details supplied for the stream in YouTube Studio. The key is passed as part of FFmpeg’s destination argument, so limit access to the machine and avoid exposing process details to other users where practical. If your security requirements do not allow the key to appear in process arguments, use an ingest method and credential handling approach appropriate to your environment.
Define the systemd service
Create /etc/systemd/system/youtube-music.service:
[Unit]
Description=YouTube music stream
Wants=network-online.target
After=network-online.target
[Service]
Type=simple
User=stream
WorkingDirectory=/srv/youtube-music
EnvironmentFile=/etc/youtube-music.env
ExecStart=/usr/local/bin/youtube-music-start
Restart=on-failure
RestartSec=15
[Install]
WantedBy=multi-user.targetRestart=on-failure retries after an abnormal exit, and RestartSec=15 waits before the next attempt. Restart attempts remain subject to systemd’s unit start-rate limiting; repeated rapid failures can leave the unit failed instead of retrying indefinitely. These are practical starting values, not a universal reliability guarantee. See the Ubuntu Noble systemd.service manual.

Enable the service and verify the broadcast
- Reload systemd’s unit files and enable the service at boot while starting it now:
sudo systemctl daemon-reloadsudo systemctl enable --now youtube-music.service - Check the service state:
systemctl status youtube-music.service - Follow its logs while it connects and begins playback:
journalctl -u youtube-music.service -f - In YouTube Studio’s Live Control Room, check the preview and stream health. Confirm that viewers can hear the audio from a separate device, and keep monitoring after the first successful connection.
A service marked active only tells you that its process is running; it does not prove that YouTube is receiving a healthy stream. YouTube recommends testing with representative audio and motion, monitoring health, and keeping about 20% upload-bandwidth headroom beyond the stream bitrate. Its encoder guidance lists RTMP/RTMPS; H.264, H.265, or AV1 video; AAC or MP3 audio; constant bitrate (CBR); and a recommended two-second keyframe interval that should not exceed four seconds. For 1080p30 H.264, YouTube lists 5 Mbps as the minimum and 14 Mbps as the recommended video bitrate. These are platform recommendations, not a promise that a given host can encode or upload reliably. See the YouTube encoder settings and stream health guidance.

What looping and automatic restart do—and do not do
FFmpeg’s -stream_loop -1 loops the input indefinitely. It does not make a failed process, disconnected network, invalid file, or rejected YouTube ingest healthy. If FFmpeg restarts, playback may begin at the start of the input rather than resuming from the point where it stopped. The FFmpeg documentation describes input looping options; systemd’s restart controls are documented in the Ubuntu Noble service manual.
Troubleshoot common failures
- The unit fails immediately: Run
systemctl status youtube-music.serviceandjournalctl -u youtube-music.service -n 100 --no-pager. Check the wrapper path, file permissions, FFmpeg path, environment file syntax, and that the service account can read the media. - The log says the key is missing or authentication fails: Confirm the variable name is exactly
YOUTUBE_STREAM_KEY, the environment file is readable by systemd, and the key belongs to the intended YouTube stream. If the key may have been exposed, reset it in Studio. - FFmpeg runs but YouTube shows no healthy input: Check the exact ingest URL and key, outgoing network access, and YouTube’s Live Control Room health panel. Verify the source codecs and output settings against YouTube’s encoder guidance.
- Audio or video is missing, unsupported, or unstable: Test the file locally with FFmpeg, inspect its streams, and use compatible output encoding instead of blindly copying codecs. Re-test using representative media before enabling the unattended service.
- The service keeps restarting or stops retrying: Inspect the journal for the original error rather than increasing restart frequency. Repeated failures can hit systemd start-rate limits; fix the underlying media, credential, or connectivity problem, then reset the failed unit with
sudo systemctl reset-failed youtube-music.servicebefore starting it again. - The stream drops despite an active unit: Check host connectivity, available upload capacity, and YouTube ingest health. A restart policy only reacts to the tracked process; it cannot repair a sustained outage or guarantee that YouTube remains connected.
- YouTube interrupts or terminates the live stream: Review the rights for every audio and visual element. A process restart cannot resolve a copyright claim or replace the required permissions.
Or let it run in the cloud
If maintaining an Ubuntu host and FFmpeg service is not the part you want to manage, StreamNeo keeps an uploaded-video YouTube stream running from the cloud:
- Upload your recording or build a playlist.
- Add your YouTube stream key once.
- Go live; StreamNeo loops the uploaded material from the cloud.
Your computer and home connection do not have to stay on. Every slot supports the uploaded quality up to 4K 60fps at one flat price per slot, and StreamNeo automatically recovers if YouTube drops the stream. The first day is free with no card. The monthly option is $9.99 per month. StreamNeo streams to YouTube and plays uploaded videos; it does not broadcast a live camera feed. Start your free day with StreamNeo.

With the systemd approach, the recurring costs depend on the Ubuntu machine or server, electricity if it is on-site, and internet service. You remain responsible for operating system updates, storage, process monitoring, network reliability, and recovery from host failure. No universal hardware sizing or VPS price follows from the stream settings alone; verify that your chosen machine can sustain the selected media and upload rate.
A managed cloud workflow shifts responsibility for keeping the local computer and connection online, but it is a different operating model: you upload prerecorded videos and supply the YouTube key rather than maintaining your own FFmpeg service. Compare based on who maintains the host, how source media is stored, what happens after a failure, and whether the workflow fits your rights and broadcast needs.
