A free scan shows the junk files, broken settings and background clutter dragging Windows down - then fixes them in one click.Free scan · Windows 10 & 11To keep a prerecorded video streaming to YouTube from an Ubuntu host, run FFmpeg as the foreground process of a systemd service, configure the service to start at boot and restart after unexpected exits, and monitor both systemd and YouTube Live Control Room. This can recover from some local process failures; it cannot fix a bad stream key, missing media, an internet outage, or a YouTube broadcast that has ended. YouTube also says streams under 12 hours are automatically archived, so a genuinely continuous channel requires attention to YouTube’s broadcast lifecycle as well as the encoder.
What you need before setting up the service
- An Ubuntu host that can remain powered on, with reliable outbound internet and enough upload capacity for the chosen stream quality.
- FFmpeg installed from a trusted package source appropriate to your Ubuntu release. Confirm that your build can read the media and supports the required encoders and network protocol.
- A prerecorded video file accessible to the account that will run the service. Test that FFmpeg can read it before configuring systemd.
- A YouTube stream created or scheduled in YouTube Studio, with its server URL and stream key available from Live Control Room.
This setup is for prerecorded media sent to YouTube by FFmpeg. It is not a camera-ingest or live-production setup. The Ubuntu machine, its network connection, and the YouTube-side broadcast are separate parts of the chain; each needs its own checks.
Create the YouTube stream and protect its key
- In YouTube Studio, create or schedule a live stream and open Live Control Room.
- Copy the server URL and stream key shown for that stream into your encoder configuration. YouTube’s setup guidance says to enter both values into the encoder (Create a YouTube live stream with an encoder).
- Prefer the RTMPS server URL provided in Live Control Room. YouTube describes RTMPS as a secure extension of RTMP that carries the connection over TLS/SSL (Encrypt your stream using RTMPS). Do not assume that a URL displayed by default is RTMPS; verify the actual URL.
- Keep the stream key private: do not commit it to a public repository, include it in screenshots, or expose it through broadly readable logs. If it is compromised, reset it in Live Control Room and update the encoder configuration (YouTube encoder setup guidance).
For an SSL error or connection failure, first check that the URL and protocol match and that the FFmpeg build supports RTMPS. YouTube’s RTMPS guidance also discusses port 443; use it where the encoder URL or configuration allows. The exact URL shown in Live Control Room takes precedence over assumptions about a default endpoint.
Choose settings that fit the source and connection
Use the source’s actual resolution and frame rate where practical, and choose a bitrate your host can sustain consistently. YouTube’s current encoder guidance supports RTMP/RTMPS, H.264, H.265 (HEVC) or AV1 video, up to 60 fps, constant bitrate (CBR), and AAC or MP3 audio. It recommends a two-second keyframe interval and says not to exceed four seconds. Check YouTube’s current settings table for the exact codec, resolution and frame-rate combination you intend to use (YouTube live encoder settings).

| Example output | YouTube-recommended video bitrate |
|---|---|
| 1080p at 30 fps, H.264 | 14 Mbps |
| 1080p at 30 fps, AV1 or H.265 | 10 Mbps |
| 720p at 30 fps, H.264 | 8 Mbps |
| 720p at 30 fps, AV1 or H.265 | 6 Mbps |
These are YouTube recommendations, not a promise that a particular machine or connection can maintain them. YouTube recommends testing upload capacity and selecting a quality that is reliable for the connection. For audio, YouTube recommends 44.1 kHz and 128 Kbps for stereo, and 48 kHz and 384 Kbps for 5.1 audio; 5.1 over RTMP/RTMPS is supported only with AAC, according to its encoder guidance.
Test FFmpeg interactively before making it a service
First run a test using the intended file, output settings, server URL and stream key. Confirm the installed FFmpeg version can read the file and that the resulting audio and video are suitable. YouTube recommends testing with audio and movement representative of the planned broadcast, then monitoring stream health in Live Control Room.

- What You Get: Anker USB-C Hub (5-in-1, 4K HDMI), welcome guide, 18-month warranty, and our friendly customer service.
For a local file that should repeat, FFmpeg options such as -stream_loop -1 can be used to loop the input, and -re can pace file input in real time. These are FFmpeg command choices, not YouTube requirements. Validate the options against the FFmpeg version installed on your Ubuntu host and the specific media. A looping input does not by itself manage YouTube’s broadcast lifecycle.
Do not put a real stream key in a public command example or a shell history you share. Keep the final configuration accessible only to the service account and administrators who need it; choose a storage method and file permissions appropriate to the Ubuntu and systemd versions on the host.

Run FFmpeg under systemd and start it at boot
Create a system-level service unit that runs FFmpeg as its main foreground process. Configure it to start on boot, send output to the journal, and use a restart policy and delay suited to the workload. Keeping FFmpeg in the foreground lets systemd track the encoder process rather than a wrapper that backgrounds it. Exact unit directives and their semantics can vary with the systemd version shipped by an Ubuntu release, so check that version’s documentation before applying a unit file.
After saving the unit, reload systemd’s unit definitions, enable the service for boot, and start it. Then inspect the service state and journal using systemctl status and journalctl for the unit. Use the actual unit name in those commands. The journal can show why FFmpeg exited or failed to start; it cannot show by itself whether YouTube is receiving a healthy broadcast.

Choose restart behavior deliberately. A process restart may help after an unexpected local exit, but repeated restarts can create a failure loop if the input path is wrong, the key is invalid, or the network is unavailable. A restart policy does not repair those underlying problems, and a clean exit, an administrator stop, or YouTube ending the broadcast must be handled according to the service configuration and platform workflow.
Verify the stream at both ends
- Check systemd: confirm the unit is loaded and active with
systemctl status. If it is inactive or repeatedly restarting, read the corresponding journal entries. - Check FFmpeg and the source: look for input-read errors, unsupported formats or encoders, and output failures. Confirm the media contains the intended audio and video and that output settings match YouTube guidance.
- Check transport: verify the exact RTMPS server URL, key, protocol support, and network access. For SSL or timeout issues, revisit the URL/protocol and port 443 guidance.
- Check YouTube: open Live Control Room and confirm the incoming preview and stream health. An active local service does not prove that YouTube has a usable broadcast.
Plan for YouTube’s 12-hour archive behavior
YouTube says streams under 12 hours are automatically archived (YouTube encoder stream guidance). Do not assume that keeping FFmpeg alive, or restarting it, creates an indefinitely open YouTube event. Plan how the YouTube-side stream will be created, monitored and continued around that lifecycle. The cited guidance establishes the archive behavior; it does not establish that restarting the encoder alone is a solution for continuous platform-side broadcasting.

Troubleshoot by failure layer
| Symptom | Likely area | What to check or do |
|---|---|---|
| Unit fails immediately or keeps restarting | Service or process | Read the unit’s journal output; confirm the executable, configuration access and media path. Correct the underlying failure before relying on another restart. |
| FFmpeg cannot open or decode the file | Input or build | Check file permissions and path, and confirm the installed FFmpeg build supports the media’s demuxer and codecs. |
| YouTube does not receive the stream | Credentials or transport | Verify the stream key and the exact server URL from Live Control Room. Prefer its RTMPS URL and confirm RTMPS support and network access. |
| SSL error or connection timeout | Transport | Check protocol and server URL together; consult YouTube’s RTMPS guidance about port 443 where the encoder configuration permits it. |
| Video or audio is unstable or unhealthy | Encoding or upload | Compare codec, frame rate, bitrate, keyframe interval and audio format with YouTube’s current settings. Test upload capacity and reduce output quality if the connection cannot sustain the chosen rate. |
| systemd says active but no healthy preview appears | YouTube broadcast | Check Live Control Room separately. Local process state alone does not confirm YouTube ingest or broadcast health. |
| Key may have been exposed | Credential security | Reset the stream key in Live Control Room and replace it in the protected service configuration. |
| Stream stops around an archive or event end | YouTube lifecycle | Check the YouTube-side stream state and plan the next event or continuation. A local FFmpeg restart does not itself reopen an ended broadcast. |
