Crashes, No Sound, or Screen Glitches?
Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteWindows Errors? Fix Them Before They Spread
Repair common Windows errors and clear accumulated junk for a smoother, more stable PC - no reinstall needed.Free scan · no reinstallTo run an always-on YouTube radio stream on an Ubuntu VPS, use FFmpeg to combine your audio with a static image or looping visual, then publish it 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 after a process failure. That helps keep the encoder running; it does not guarantee uninterrupted playback, because YouTube ingest, VPS networking, source files, and channel status also matter.
What you need before you start
- An Ubuntu VPS with sustained outbound bandwidth and enough CPU for the encoding settings you choose. There is no universal VPS plan size established here; test the actual machine with your intended audio, visual, resolution, and codec.
- FFmpeg installed with support for your chosen codecs and RTMPS/RTMP output. Confirm the installed build supports the protocols and encoders you intend to use.
- A YouTube channel eligible to go live. YouTube’s current help guidance requires channel verification, no live-stream restriction within the preceding 90 days, and a creator who is at least 16 years old: YouTube live-streaming eligibility.
- Audio and visual material you are entitled to stream, plus a YouTube Live event and its current RTMPS URL and stream key.
For radio, the audio is the main content; the video track can be a still image or a looping visual. Make the visual part of the FFmpeg input pipeline rather than assuming an audio-only feed will satisfy your intended YouTube presentation.

- Open YouTube Live Control Room, create or schedule a live stream, then open Stream settings.
- Reveal and copy the RTMPS server URL and stream key for that stream configuration. Obtain credentials from your own account; never use a key copied from an example or another person’s guide.
- Prefer the RTMPS URL. YouTube recommends RTMPS for encrypted transport, and its developer guidance specifies the RTMPS protocol, valid ingest endpoint and application path, and port 443: YouTube encoder settings and ingest guidance and RTMPS ingestion protocol.
Treat the key like a password. Avoid putting it in public scripts, screenshots, shell history, or logs. Keep it in a private configuration file with access limited to the account that runs FFmpeg. If you rotate or replace the key in Live Control Room, update the VPS configuration too.
Choose compatible encoder settings
YouTube’s encoder guidance supports RTMP/RTMPS; H.264, H.265 (HEVC), or AV1 video; AAC or MP3 audio; up to 60 fps; and constant bitrate. It recommends a 2-second keyframe interval and says not to exceed 4 seconds. For stereo audio, its guidance is 44.1 kHz at 128 kbps. These are YouTube configuration recommendations, not a guarantee that a particular VPS can encode them smoothly.

| Video setting | H.264 bitrate guidance from YouTube | When it may fit a radio stream |
|---|---|---|
| 720p at 30 fps | 3 Mbps minimum; 8 Mbps recommended | A simple station image or modest visual where 720p is adequate. |
| 1080p at 30 fps | 5 Mbps minimum; 14 Mbps recommended | A sharper visual or audience preference that warrants the additional bitrate. |
The figures above are YouTube Help recommendations; the page reviewed does not state a publication year. A radio station with a static or low-motion visual may not need 1080p. Select a resolution for the actual artwork and audience rather than increasing it by default. YouTube’s guidance: encoder settings, bitrates, and resolutions.
Check that the VPS can sustain the total outbound bitrate with margin. YouTube recommends approximately 20% bandwidth headroom beyond the stream’s aggregate bitrate: YouTube network guidance. Verify sustained upload from the VPS itself, and test CPU load using a representative stream. A provider’s advertised network or CPU specification is not proof that the selected encode will remain stable.

Build and test the FFmpeg publishing command
FFmpeg documents the general real-time file publishing pattern as ffmpeg -re -i myfile -f flv rtmp://myserver/live/mystream. This is a protocol example, not a complete YouTube-ready command: it has no radio-specific audio/video inputs, codec settings, or actual YouTube credentials. Adapt the input and output options for your media, installed FFmpeg build, and YouTube stream settings. FFmpeg protocol documentation: RTMP protocol.

For a radio feed, decide how the audio and picture enter the pipeline before publishing: the audio may be a file or a playlist, while the visual may be a still image or a looping video. Ensure that the inputs continue producing data for the full intended session, and that the output uses the chosen video and audio codecs, constant bitrate, frame rate, resolution, and keyframe interval. Check the command locally with a short test before connecting it to a public event.
- Run a short, unlisted or private test stream from the VPS before relying on the setup.
- Check the Live Control Room preview and stream health while the test is running; listen to the watch-page output if accessible.
- Confirm the FFmpeg process is alive, its logs do not show input exhaustion or encoder errors, CPU use is sustainable, and outbound network capacity remains adequate.
- Test what happens when FFmpeg exits, the VPS reboots, or its network briefly drops. Do not assume a restarted encoder automatically resumes the intended YouTube live event.
Keep FFmpeg running after reboot or failure
On Ubuntu, use a service manager such as systemd to start the encoder at boot, restart it after an unexpected process exit, and make logs available for diagnosis. Store the command and sensitive stream key in a private configuration arrangement rather than embedding credentials in a publicly readable script. The exact unit file depends on the VPS, user, media paths, and chosen FFmpeg pipeline; there is no provider-neutral unit configuration established here, so verify the service against your own machine and account.
Process supervision is not end-to-end stream monitoring. A service manager can relaunch a crashed FFmpeg process, but it cannot establish that YouTube is accepting the new connection, that the live event is still valid, that a source file has not ended, or that viewers see and hear the intended output. Monitor both the service and Live Control Room.

Monitor stream health and troubleshoot failures
YouTube’s LiveStreams API distinguishes stream states such as active, ready, inactive, and error, and health values including good, ok, bad, and noData. These signals can help separate an encoder process that is running from an ingest or stream-health problem: LiveStreams API reference. YouTube also recommends test runs and ongoing stream-quality monitoring.
| Symptom | Likely cause to check | What to do |
|---|---|---|
| FFmpeg exits or the stream stops when the VPS restarts | The encoder is not managed as a boot-time service, or it exits on a source or encoding error. | Check service status and logs, configure process supervision, then test reboot and restart behavior with a non-public test event. |
| FFmpeg runs but Live Control Room reports no data or poor health | The process may not be sending valid output, the source may be exhausted, or ingest may reject the stream. | Check the preview and health status, inspect FFmpeg logs, confirm inputs are still producing data, and verify the codecs and output settings. |
| RTMPS connection fails with an SSL error or timeout | Wrong URL or path, non-RTMPS address, blocked port 443, or a client/build without needed protocol support. | Copy the current RTMPS URL from Stream settings; confirm the hostname, application path, port 443, and protocol support. YouTube’s RTMPS guide notes that the hostname is needed for SNI authentication during the TLS handshake: RTMPS ingestion details. |
| Output freezes, drops frames, or becomes unstable | Insufficient sustained outbound capacity, inadequate headroom, CPU overload, or an input that stops advancing. | Measure outbound capacity from the VPS, preserve YouTube’s recommended 20% bandwidth headroom, inspect CPU and FFmpeg logs, and test a lower resolution or bitrate if needed. |
| Music stream is interrupted or replaced | Third-party content detection, missing rights, or a rights-owner Content ID allowlist issue. | Use cleared content and check YouTube’s live-copyright guidance and any required allowlisting before going live. |
A restart policy addresses only one failure class: an exited process. Plan separately for exhausted media, a VPS reboot, network interruptions, YouTube-side errors, and the behavior of the specific live event after reconnection.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Plan replays and archives for a continuous station
YouTube says streams shorter than 12 hours can be automatically archived, while streams exceeding 12 hours may not be captured at all. That means a 24/7 station should not promise viewers one complete YouTube replay. If replays matter, use planned shorter sessions with deliberate transitions or record a separate local archive, and verify disk capacity and recording rotation. YouTube recommends keeping a local archive backup: YouTube live-stream archives.

Clear music and visual rights before broadcasting
YouTube’s live-stream terms place responsibility on the creator to hold the necessary worldwide rights for live content, including music licensing rights from artists, labels, publishers, public-performance licensing, and other royalty participants: YouTube Terms of Service. A subscription to a music service or possession of an audio file does not by itself establish that you have the rights needed for a public live broadcast; confirm the relevant permissions for your use and territory.
YouTube scans live streams for third-party content. Detected material can trigger a warning, replacement with a placeholder, interruption, or termination. YouTube also says a stream can be interrupted even when the creator has a license if the channel has not been added to the rights owner’s Content ID allowlist: YouTube live-stream copyright guidance. Check rights for the visual as well as the music.
