You can run a continuous YouTube playlist with FFmpeg sending video to an NGINX RTMP relay, which forwards it to YouTube Live. NGINX is optional: an encoder can also send directly to YouTube. The setup below uses the separate third-party arut/nginx-rtmp-module, not NGINX Plus’s packaged dynamic module. Your exact installation and playlist command depend on your operating system, NGINX build, FFmpeg version, and media files, so validate those parts on the machine you will run.
Choose how the stream will reach YouTube
The components have separate jobs: FFmpeg reads and sends the playlist; YouTube provides the ingest URL and stream key; NGINX can accept FFmpeg’s RTMP feed and relay it onward. You do not need NGINX just to stream to YouTube.
| Design | What happens | When it fits |
|---|---|---|
| FFmpeg directly to YouTube | FFmpeg reads the media and publishes to YouTube’s ingest URL with the stream key. | Use this when you do not need an intermediary. |
| FFmpeg → NGINX RTMP → YouTube | FFmpeg publishes to an RTMP application on your NGINX host; the RTMP module relays the feed to YouTube. | Use this when you specifically need an RTMP relay stage or want to separate the local encoder endpoint from the destination. |
The relay does not make a computer-based FFmpeg sender self-healing or eliminate the need to monitor it. If you need an always-on YouTube stream without keeping a computer or server running at home, see StreamNeo after the setup guide.
Pick the NGINX RTMP implementation
Third-party arut module used in this guide
arut/nginx-rtmp-module is a third-party project, separate from NGINX’s commercial module packaging. Confirm that its source, your NGINX version, operating system, and build method are compatible before installing. Its project README and directive reference describe the module and RTMP application directives.

NGINX Plus is a different installation path
NGINX’s RTMP dynamic-module guide documents the NGINX Plus route: install the package for the supported platform, load ngx_rtmp_module.so, test the configuration with nginx -t, and reload NGINX. Those package instructions are for NGINX Plus; do not assume they install the third-party arut module or apply to every NGINX build. Check the NGINX technical specifications for platform and version compatibility.
Install and configure the RTMP relay
Install a compatible build
- Choose the module implementation and confirm it supports your operating system and NGINX build.
- Install or build that implementation using its own documentation. Package names, build flags, and module paths vary; there is no universal installation command for all NGINX installations.
- For a dynamic module, load the module in the NGINX configuration using the path and syntax required by that build. For NGINX Plus, follow the official dynamic-module guide rather than copying its package steps to another edition.
- Restrict inbound RTMP access to the encoder host or trusted network with firewall rules. Do not expose an unauthenticated publishing endpoint to the public internet.
Add an RTMP application
For the arut module, a minimal relay application has the following shape. Place the rtmp block at the appropriate top level in the configuration for your build; do not paste it inside the HTTP server block. Replace the destination placeholder with the YouTube server URL and stream key from Live Control Room, and protect the resulting configuration because it contains a secret.

}This is an example of the third-party module’s RTMP application pattern, not a universal NGINX configuration for all module implementations. Verify directive support and syntax against the documentation for the exact module and build you installed. The example uses RTMP for the outbound push; prefer YouTube’s RTMPS ingest URL when the selected module and configuration support it.
- Save the configuration and run
nginx -tusing the configuration file and binary for the NGINX instance you intend to run. - If the test succeeds, reload that instance using its normal service manager or documented reload method. If it fails, inspect the reported file and line before reloading.
- Allow RTMP traffic to the relay only from the FFmpeg sender. Keep the relay’s publishing endpoint and YouTube key private.
Do not confuse this RTMP relay with NGINX’s separate HTTP HLS module. The NGINX HTTP HLS module serves HLS from MP4/MOV and is part of NGINX’s commercial subscription; it is not the RTMP module used in this guide.

Prepare the playlist and FFmpeg sender
There is no single playlist-loop command that is guaranteed to work for arbitrary media, FFmpeg builds, and timestamp or codec combinations. Validate the chosen loop or concat method with your installed FFmpeg version and representative files before relying on it for a long-running broadcast. Check file ordering, timestamps, codec compatibility, audio continuity, and how the sender behaves at the end of the playlist.
- Prepare the files in the intended order and test transitions, including the first-to-last loop boundary. Confirm that each file has the audio and video streams you expect.
- Decide whether the input can be stream-copied or must be transcoded. Copying avoids an encode step only when the inputs and output requirements are compatible; mixed codecs, frame rates, dimensions, timestamps, or audio formats may require normalization. CPU needs depend on the actual media and settings.
- Configure FFmpeg to publish to the NGINX host’s RTMP application, for example a destination shaped like
rtmp://NGINX_HOST/ingest/STREAM_NAME. That is the local relay endpoint, not the YouTube key. - Test the exact playlist command against the deployed FFmpeg build. Confirm the stream starts, loops in the right order, maintains continuous audio and video, and recovers as intended after an input or network interruption.
The module’s relay configuration sends the accepted feed to YouTube. In a direct-output design instead, configure FFmpeg’s output with YouTube’s ingest URL and key, not the local NGINX address.

Get YouTube’s ingest URL and key
- Open YouTube Studio and go to Live Control Room; create or select the live stream using YouTube’s encoder setup instructions.
- Copy the server URL and stream key shown for that stream. Enter them in the encoder or relay destination as appropriate. YouTube describes the key as a password/address that allows it to accept the feed; treat it as a secret, do not publish it, and reset it if it is exposed.
- Use YouTube’s RTMPS URL when your chosen encoder or relay supports it. YouTube recommends RTMPS, the encrypted extension of RTMP. If a component cannot connect over RTMPS, confirm its supported protocol and use an appropriate compatible configuration.
For the NGINX relay pattern above, the key appears in the NGINX push destination. Limit access to the configuration file and avoid placing the key in public logs, screenshots, shared scripts, or source control.

| Output | YouTube-recommended H.264 bitrate |
|---|---|
| 1080p at 30 fps | 5 Mbps |
| 720p at 60 fps | 8 Mbps |
These are YouTube’s recommendations, not a guarantee that a particular uplink can sustain the feed. Choose a bitrate and output your connection can maintain, and consult YouTube’s encoder settings and bitrate table for other resolutions and frame rates. For RTMPS details, see YouTube’s RTMPS guidance.
- Start with a representative section that includes moving video and audio; confirm the relay receives it and YouTube shows the expected preview.
- Use YouTube’s test workflow and check Live Control Room’s stream-health messages before making the stream public. YouTube’s live streaming tips recommend testing and monitoring stream quality.
- Watch for dropped frames, unstable bitrate, audio gaps, and errors at playlist transitions. Change one relevant setting at a time, then test again.
- Verify that the host can sustain the selected bitrate and that the FFmpeg process continues through the loop. Monitor both the local sender and the YouTube stream rather than assuming that a successful NGINX configuration means the full path is healthy.
Plan for failures and long-term operation
A 24/7 stream depends on the media sender, relay, network path, and YouTube ingest all remaining healthy. Decide how an operator will detect and restart a failed FFmpeg or NGINX process, and validate that recovery behavior on the chosen host and service manager. The exact supervision and restart implementation varies by deployment; a running NGINX process alone does not prove that FFmpeg is still sending or that YouTube is receiving a healthy feed.
- Monitor process status, logs, YouTube stream-health messages, and whether local recording files continue to grow if you are recording.
- Test recovery from a stopped sender, an interrupted network connection, and a restarted relay before treating the setup as unattended.
- Keep a tested copy of the configuration and document how to replace a compromised YouTube key.
- Monitor picture and sound quality over time, not only during initial setup. YouTube’s live tips advise testing and checking stream health and quality.
Choose an archive plan for a 24/7 stream
A continuous broadcast is not a dependable single YouTube archive. YouTube says streams under 12 hours can be automatically archived, but a stream exceeding 12 hours may not be captured at all. See YouTube’s archive guidance.
- If retaining the full programme matters, arrange independent local recording and check that the recording is actually growing and playable.
- Alternatively, divide programming into shorter live sessions and verify that each resulting archive is available and complete.
- Do not assume that a 24/7 stream will yield one complete replay, even if the live broadcast remains online.
