To run an always-on YouTube radio stream on an Ubuntu VPS, use FFmpeg to combine your audio with a static or looping visual and send the output to the RTMPS address and stream key shown in YouTube Live Control Room. Run FFmpeg under a process supervisor such as systemd so it can start at boot and restart if it exits. That handles the encoder process—not every possible interruption: YouTube ingest, the VPS network, channel status, and your source files also matter.
What you need before you start
- An Ubuntu VPS with enough sustained outbound bandwidth for your stream and enough CPU for the encoder settings you choose. There is no universal VPS size established for this workflow; test the actual setup under load.
- FFmpeg installed with support for the output protocol and codecs you intend to use.
- A YouTube channel eligible to livestream, plus a stream configuration in Live Control Room.
- Audio and visual material you have the rights to use on YouTube.
Enable live streaming on the channel and check YouTube’s current eligibility requirements: channel verification, no live-stream restriction in the previous 90 days, and creator age of at least 16. See YouTube’s live-streaming eligibility guidance for current account requirements.
Get the YouTube RTMPS address and stream key
- Open YouTube Live Control Room and create or schedule a stream.
- Open the stream’s Stream settings.
- Reveal and copy the RTMPS URL and stream key shown for that stream configuration.
Use the URL and key from your own account; do not reuse sample credentials from a guide. Keep the key private: anyone who obtains it may be able to send video to your stream. YouTube recommends RTMPS, the encrypted extension to RTMP. Its ingest guidance requires the RTMPS protocol, a valid YouTube ingest endpoint and application path, and port 443. The RTMPS hostname is also needed for SNI authentication during the TLS handshake. See YouTube’s encoder settings guidance and the RTMPS ingestion guide.

Choose audio, video, and encoder settings
A radio stream still needs a video signal. Use a still image or looping video that you are entitled to use, and choose a resolution that suits the visual rather than assuming the feed needs to be 1080p. YouTube’s guidance supports RTMP/RTMPS, H.264, H.265 (HEVC), or AV1 video, AAC or MP3 audio, and up to 60 fps. It recommends constant bitrate (CBR), a 2-second keyframe interval (no more than 4 seconds), and stereo audio at 44.1 kHz and 128 kbps. Confirm that your installed FFmpeg build supports your chosen codec and output path.

| H.264 output | Minimum bitrate | Recommended bitrate |
|---|---|---|
| 720p30 | 3 Mbps | 8 Mbps |
| 1080p30 | 5 Mbps | 14 Mbps |
These are YouTube’s stated H.264 bitrate values; the page reviewed does not state a publication year. YouTube recommends about 20% upload-bandwidth headroom beyond the aggregate stream bitrate. Check sustained outbound capacity from the VPS, not just a provider’s advertised port speed. Encoding also consumes CPU; make a representative test with your chosen resolution, frame rate, and codecs before relying on the VPS for continuous operation. See YouTube’s encoder settings and bitrate recommendations and its network guidance.
Publish a test stream with FFmpeg
FFmpeg documents real-time file publishing with -re and FLV output to an RTMP server. Its documented example is ffmpeg -re -i myfile -f flv rtmp://myserver/live/mystream. This illustrates the protocol, not a complete, tested YouTube command: adapt the inputs, encoding options, output URL, and key for your media and account, and confirm that your FFmpeg build supports the selected protocols and codecs. See FFmpeg’s protocol documentation.

Do not put a real stream key in a public script, shared command history, or logs. Use a configuration approach with access restricted to the account that runs the encoder, and avoid printing secrets when diagnosing errors. Before switching to a public broadcast, run an unlisted or private test and check both the Live Control Room preview and stream health.
Run FFmpeg unattended with process supervision
On Ubuntu, systemd can start the encoder at boot, restart it after a process failure, and retain logs for diagnosis. Configure the service to run as a restricted user and to read its media and secret configuration only from appropriately permissioned locations. The correct unit and restart policy depend on your FFmpeg command and VPS; there is no provider-independent, ready-made unit established here.

Process supervision is not an end-to-end uptime guarantee. A successful restart does not prove YouTube is receiving valid video, that a reconnect will resume the same live event, or that the stream has not been stopped by channel or rights issues. Test VPS reboot, FFmpeg exit, source-file exhaustion, network loss, and YouTube-side errors with the real account before treating the station as unattended.

Check the Live Control Room preview and health indicators, confirm the watch page is accessible as intended, and monitor the FFmpeg process, logs, CPU, and outbound network. YouTube’s LiveStreams API defines stream states active, ready, inactive, and error, and health statuses including good, ok, bad, and noData.

| Symptom | What to check | Practical response |
|---|---|---|
| RTMPS SSL error or timeout | Confirm the copied URL starts with rtmps, uses the correct server and path, and connects on port 443; check that the FFmpeg build supports the protocol and TLS/SNI requirements. |
Copy the current URL again from Stream settings and verify VPS egress and DNS. Consult the RTMPS ingestion guide. |
| FFmpeg is running, but YouTube shows no data or poor health | Check the Live Control Room health status, encoder output, selected codecs, and whether the correct stream key is configured. | Use an unlisted test, inspect logs without exposing the key, and verify the stream’s video and audio settings against YouTube’s encoder recommendations. |
| Stream stops when media ends | Determine whether the input is a finite file or a playlist that actually advances or loops. | Configure and test source rotation or looping explicitly; a process supervisor cannot supply missing media. |
| Encoder exits or VPS reboots | Check systemd status and logs, permissions, available CPU, and whether the service is enabled for startup. | Correct the underlying error, then test restart and YouTube reconnection behavior. A process restart alone does not verify the live event recovered. |
| Stream is interrupted despite a valid music licence | Check YouTube’s copyright notification and whether the rights owner has allowlisted the channel in Content ID. | Resolve the rights issue with the relevant rights owner and YouTube; a licence does not necessarily prevent an interruption if the channel is not allowlisted. |
Plan for archives and long sessions
YouTube says streams shorter than 12 hours can be automatically archived, while streams longer than 12 hours may not be captured at all. It recommends keeping a local archive backup. If replays matter, plan shorter sessions with a deliberate transition, or record locally as a separate task and manage disk capacity and recording rotation. Do not assume a continuous 24/7 broadcast will produce one complete replay. See YouTube’s live-stream archive guidance.

YouTube’s live-stream terms require creators to have the necessary worldwide rights to exploit live content on Google services, including music licensing rights from artists, record labels, publishers (including public performance licences), and other royalty participants. See the YouTube Terms of Service.
YouTube scans live streams for third-party content. If it detects such content, it may warn you, replace the stream with a placeholder, interrupt it, or terminate it. Even when you hold a licence, YouTube says the stream may be interrupted if the channel has not been added to the rights owner’s Content ID allowlist. Clear both audio and visuals for the intended use before broadcasting. See YouTube’s copyright guidance for live streams.
