1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsUse a system-level systemd service to start FFmpeg at boot and restart it when the process fails. First confirm that FFmpeg can read your playlist and YouTube accepts the stream; systemd supervises FFmpeg, but it cannot fix bad media, credentials, network access, or a YouTube event that is no longer live.
What systemd can—and cannot—keep running
A systemd service manages FFmpeg’s process lifecycle: it can launch the program at boot, restart it according to a policy, and send its output to the system journal. That is process supervision, not an end-to-end broadcast health check. A running FFmpeg process does not prove that YouTube is receiving video or that viewers can watch it. Check both the service logs and YouTube Live Control Room.

This guide uses an illustrative service setup. Validate the command and unit directives against the FFmpeg build and systemd version installed on your Ubuntu host before relying on it. Do not put a real stream key in a publicly readable unit file or publish it in logs.

Run FFmpeg as a dedicated, unprivileged Linux account rather than as root. Create an account and a directory for the videos using your normal Ubuntu administration process. Ensure the account can read every playlist file and any playlist text file, and can access the working directory. The account also needs network access to YouTube.
#1 Best Overall
Keep media paths simple and use absolute paths in the command. Spaces, misspelled filenames, unreadable directories, or files moved after playlist creation can prevent playback or cause FFmpeg to exit.
2. Check FFmpeg and its available protocols
Confirm the executable exists and inspect the protocols supported by that specific build:
ffmpeg -version
ffmpeg -protocolsFFmpeg has sequence-reading options such as the concat and concatf protocols for reading multiple resources in order. Available protocols depend on how FFmpeg was built, so do not assume a protocol listed in instructions for another Ubuntu release or package is available on your host. Consult the FFmpeg protocol documentation for the installed build: FFmpeg Protocols Documentation.

Before creating a service, run your exact FFmpeg command interactively as the dedicated account. Use the playlist input method supported by your FFmpeg build, then confirm that files advance in the intended order and that YouTube receives the stream. This is where to resolve missing files, unsupported protocols, incompatible media parameters, and output settings.
Use your own current YouTube stream URL and key from Live Control Room. Keep the key secret. The output settings must match the ingestion protocol selected for that YouTube event; an RTMP command and an HLS command are not interchangeable.
Choose the YouTube output protocol deliberately
YouTube Help’s HLS setup specifies an HTTPS URL and HLS stream key, TS segments, segment durations from 1 to 4 seconds, a rolling playlist with no more than five outstanding segments, and HTTPS POST/PUT requests. YouTube describes HLS as higher latency than continuous RTMP ingestion. These requirements apply to HLS, not to an RTMP command. See YouTube Help: Set up an HLS stream and follow the current settings shown for your event.
Do not substitute an HLS URL or key into an RTMP command, or assume your FFmpeg build can produce every required output format. Confirm protocol support locally and verify ingestion in YouTube Live Control Room.
4. Create a system-level service
Once the foreground command works, create a system service that runs as the dedicated account, starts from an explicit working directory, and uses the same command and arguments you validated. A unit should make its restart intent and delay explicit. The following is a structural example only; replace the illustrative values and validate the directives with the systemd manual available on your Ubuntu release. It deliberately contains no stream key.
[Unit]
Description=FFmpeg YouTube playlist stream
Wants=network-online.target
After=network-online.target
[Service]
Type=simple
User=streamer
Group=streamer
WorkingDirectory=/srv/youtube-playlist
ExecStart=/usr/bin/ffmpeg [your validated input and output arguments]
Restart=on-failure
RestartSec=5s
[Install]
WantedBy=multi-user.targetThe bracketed command text is explanatory, not valid FFmpeg syntax: replace it with the complete command that succeeded in the foreground. If the command needs secrets, do not paste a real key into a unit file that other users can read or into an argument likely to appear in logs or process listings. Protect credentials using a method appropriate to your host’s permissions and verify how your chosen method interacts with systemd.
Choose the restart policy for the intended behavior
Restart=on-failure expresses the intent to restart after an abnormal failure, rather than after every clean exit. A service configured to restart after every exit has different behavior: it may repeatedly relaunch a command that intentionally completed. Set a delay with RestartSec so a failing process does not immediately enter a tight restart loop. Check the installed systemd.service manual for exact directive semantics on your Ubuntu version.
5. Reload systemd, enable the service, and inspect it
After saving the unit under a system service location such as /etc/systemd/system/ with a descriptive .service filename, reload systemd’s unit definitions, enable the service at boot, start it now, and inspect its status and logs. Replace ffmpeg-youtube.service below with your actual unit name.
sudo systemctl daemon-reload
sudo systemctl enable --now ffmpeg-youtube.service
sudo systemctl status ffmpeg-youtube.service
sudo journalctl -u ffmpeg-youtube.service -fThe status command reports systemd’s view of the process. The journal helps identify startup errors, unreadable files, and FFmpeg failures. Neither is a substitute for checking YouTube Live Control Room to confirm that the event is receiving a live stream.
6. Test recovery and the viewer-facing stream
-
Confirm the service is active and the playlist is advancing in its logs.
-
While monitoring the journal, deliberately stop the FFmpeg process through the service manager—for example, with
sudo systemctl kill ffmpeg-youtube.service—and observe whether systemd starts it again under the selected restart policy. Do not use this test while a broadcast interruption would be harmful. -
Check YouTube Live Control Room independently. Confirm the event still shows the expected incoming video and remains live; a restarted local process does not itself guarantee that YouTube resumed the same event.

7. Account for Ubuntu updates and long-running service maintenance
Long-running services can be affected by maintenance. Ubuntu Server documentation says that beginning with Ubuntu 24.04 LTS, needrestart automatically restarts affected services by default after unattended upgrades. Administrators can change whether affected services restart automatically or are listed for manual action, and can exclude named critical services. This behavior is version-sensitive; check the documentation and configuration for the Ubuntu release you actually run: Ubuntu Server: Automatic updates.
Troubleshoot common failures
The service exits immediately
Read systemctl status and the unit’s journal output. Check that the executable path is correct, the command is the same one that worked interactively, the working directory exists, and the service account can read the media and playlist files.
FFmpeg reports an unavailable protocol
Inspect the installed build with ffmpeg -protocols. A sequence protocol documented elsewhere may not be enabled in your package. Adjust the input method to one supported by the local build and validate it in the foreground.
The playlist does not advance or a file is skipped
Check ordering and spelling in the playlist, use absolute paths, and verify read permissions for every file. Test the exact playlist input as the service account. Also check that the media files have compatible stream parameters for the way you are feeding them to FFmpeg.
Recommended Free Tools
FFmpeg runs, but YouTube shows no incoming stream
Confirm the event is live-ready in YouTube Live Control Room and that the current stream URL, key, and selected ingestion protocol match the FFmpeg output. For HLS, check the YouTube-specific HTTPS, TS segment, segment-duration, rolling-playlist, and request-method requirements; do not apply those HLS rules to RTMP.
Best Value
The service restarts repeatedly
A restart policy cannot repair a persistent command, media, credential, or network error. Inspect each failure in the journal, correct the underlying cause, and retain a deliberate restart delay. Avoid a policy that restarts after clean exits unless that is the behavior you intend.
The service is active but the broadcast is not healthy
Systemd reports process state, not viewer-facing delivery. Check the FFmpeg logs and YouTube Live Control Room separately. If Ubuntu maintenance restarted the service, confirm that FFmpeg reconnected and that YouTube is receiving the stream again.
