You can stream a folder of videos to YouTube Live from a headless Ubuntu VPS with FFmpeg: create an ordered playlist, send its output to the RTMPS ingest URL and stream key from YouTube Live Control Room, then check YouTube’s preview and stream health. A playlist-and-systemd setup is an implementation approach, not a YouTube-prescribed recipe; test your actual files and VPS before relying on it for a long broadcast.
How the setup works
FFmpeg reads video files on the VPS, produces a continuous output, and sends it to YouTube over RTMPS. You do not need a desktop or OBS for this pipeline. The VPS still needs enough upload capacity for the output bitrate, and enough CPU if you transcode instead of copying compatible streams.
A community Ubuntu example describes an FFmpeg-only playlist pipeline and running it as a systemd service. Its commands are examples, not a guarantee that arbitrary files or every Ubuntu FFmpeg build will work. The exact Ubuntu release, FFmpeg build, source files, network capacity, and desired broadcast duration all affect implementation.
Prepare and order the video files
Make the playlist deliberate
Decide the order explicitly. Do not assume a shell wildcard will sort files in the order you intend. Create an FFmpeg-compatible playlist that names each file in sequence, and verify every path from the directory where the service will run. FFmpeg concat-list syntax and quoting requirements depend on the file names and chosen workflow; check the installed FFmpeg documentation before using a particular list format.

Check compatibility before streaming
Compare the files’ video and audio codecs, dimensions, frame rates, and audio layouts. A playlist made from similar files is simpler to send consistently. If properties differ, test transitions between files; you may need to normalize them to a common output profile. Stream copying compatible encoded streams can reduce VPS CPU use. Re-encoding can give you control over bitrate, frame rate, and keyframes and can help normalize mixed inputs, but it requires more CPU. This is an engineering trade-off, not a guarantee that a given VPS can encode a particular profile.
Choose YouTube-compatible output settings
YouTube’s encoder guidance, accessed in 2026, lists RTMP/RTMPS as protocols; H.264, H.265/HEVC, and AV1 as video codecs; AAC or MP3 audio; and frame rates up to 60 fps. It recommends constant bitrate (CBR), a two-second keyframe interval, and says not to exceed four seconds. For SDR it recommends Rec. 709 color space and 8-bit depth. For stereo audio, its guidance lists 44.1 kHz and 128 Kbps; for 5.1 audio, 48 kHz and 384 Kbps. See YouTube’s live encoder settings for the current table and requirements.

Choose resolution and frame rate to suit the source material and the upload capacity you have measured from the VPS. YouTube’s table gives these examples for 30 fps: H.264 at 1080p has a 5 Mbps minimum and 14 Mbps recommended bitrate; AV1 or H.265 at 1080p has a 4 Mbps minimum and 10 Mbps recommended bitrate; H.264 at 720p has a 3 Mbps minimum and 8 Mbps recommended bitrate. These are YouTube ingest recommendations, not proof that your VPS or route can sustain the rate. Use the current YouTube table for your exact codec, resolution, and frame rate rather than treating one figure as universal.
For a basic SDR output, H.264 video with AAC audio is a conservative supported combination. Match the output profile to the files where practical, and test the VPS under the intended encoding load. Re-encoding mixed files may improve consistency, but a process that starts successfully does not establish that the stream is healthy.

Get the YouTube ingest URL and stream key
- Open YouTube Live Control Room and create or select the live stream you intend to use.
- In the stream settings, reveal and copy the RTMPS URL and stream key shown for that stream. YouTube recommends RTMPS, which protects the RTMP connection with TLS/SSL. Follow YouTube’s instructions for revealing the URL and retrieving the key: Stream using RTMPS.
- Configure FFmpeg with the exact endpoint details. YouTube’s API calls the primary ingest URL
ingestionAddressand the assigned stream namestreamName. Some encoders accept these separately; others use a combined form such asSTREAM_URL/STREAM_NAME. Follow the format your FFmpeg setup expects rather than assuming the two fields are interchangeable. See the YouTube Live Streams API documentation.
Treat the stream key as a password: do not commit it to a public repository or place it in a publicly readable script. Restrict access to any configuration file that contains it, and rotate the key if it is exposed. These are prudent security practices; YouTube’s documentation identifies the key as an encoder credential but does not prescribe a VPS-specific secret-storage method.
If RTMPS connection or certificate errors occur, verify that the URL begins with rtmps. YouTube also says to try port 443 where needed. Confirm that the VPS firewall and network allow the connection and that the installed FFmpeg build supports the TLS/RTMPS protocol; not every package build has identical capabilities.

Run the playlist through FFmpeg
The broad pattern is to point FFmpeg at the ordered playlist, choose either compatible stream copy or a deliberate transcode, and direct the output to the endpoint and key from Live Control Room. Exact command flags depend on the playlist format, whether you copy or encode, and how that FFmpeg build accepts the endpoint details. The available official YouTube documentation does not prescribe a universal FFmpeg concat command for an Ubuntu folder playlist, so do not assume one command will work unchanged for mixed files.
Before putting the command into unattended use, run it interactively and watch the FFmpeg output for input, mapping, encoding, and connection errors. Confirm that the output contains the intended video and audio streams. If the files have varying formats, test a transition between each kind of file you expect to include.

Keep an unattended process supervised
If the VPS should run without an operator logged in, use a process supervisor such as systemd to start FFmpeg and restart a process that exits unexpectedly. The community example uses systemd restart behavior. Configure the service for the correct working directory and playlist paths, keep secrets out of world-readable files, and inspect the service logs when it fails.
A systemd restart can restart a failed local process; it cannot ensure network continuity, manage every YouTube broadcast lifecycle state, or prove that a resumed stream is healthy. A restart loop can also hide a persistent configuration problem, so check logs and YouTube’s stream status rather than treating “service active” as success.
Preflight and monitor the broadcast
- Run a representative test with the same playlist, output settings, VPS, and network path you plan to use. YouTube explicitly advises testing before going live.
- Wait for the YouTube preview and check that motion, resolution, frame rate, and audio are present and correct.
- Review stream health messages in Live Control Room while the encoder is sending data. YouTube’s API health information can flag issues such as low or high video bitrate, missing audio, unsupported audio codec, audio sample-rate problems, keyframe interval problems, frame-rate mismatch, and unsuitable stream configuration.
- Only rely on the setup after checking file transitions and confirming the output remains stable under the VPS’s intended load.
YouTube’s Live Streams API documentation, last updated 2026-09-14 UTC, describes stream status and health diagnostics. A running FFmpeg process is not a substitute for checking those YouTube-side indicators.
Troubleshooting common failures
YouTube does not receive video
- Recheck the exact RTMPS URL and stream key in Live Control Room; make sure the key belongs to the selected stream.
- Check that the VPS can reach the endpoint, that firewall rules allow the connection, and that FFmpeg supports RTMPS/TLS. If a certificate or connection issue persists, verify the scheme and try port 443 where needed.
- Inspect FFmpeg and systemd logs for authentication, connection, or input-file errors.
The preview has no audio
- Confirm the source file actually contains audio and that the FFmpeg output includes and maps an audio stream.
- Use an audio codec supported by YouTube’s encoder guidance, and check the sample rate and channel layout against the output profile.
- Check YouTube’s health messages for missing audio, unsupported codec, or sample-rate warnings.
The stream buffers or YouTube flags bitrate, frame rate, or keyframes
- Compare the actual output bitrate with YouTube’s current recommendation for the codec, resolution, and frame rate you selected.
- Use CBR and set a two-second keyframe interval; do not exceed four seconds, per YouTube’s guidance.
- Reduce the output demands or select a profile the VPS upload path can sustain. A recommendation is not a measured capacity test for your host.
Playback breaks at playlist boundaries
- Compare codecs, dimensions, frame rates, and audio layouts across the files.
- Test boundaries before relying on the playlist. If inputs are inconsistent, normalize them to one output profile and retest; transcoding uses additional VPS CPU.
- Check for bad paths, unsupported media, or a playlist ordering problem if FFmpeg stops or skips a file.
The service keeps restarting
- Inspect systemd and FFmpeg logs to identify whether the cause is an invalid playlist, missing file, bad endpoint or key, or resource exhaustion.
- Correct the underlying error before relying on automatic restart; repeated restarts do not repair a configuration error or guarantee a healthy YouTube broadcast.
