1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesYou can run a pre-recorded YouTube stream continuously from an Ubuntu virtual machine in Azure by installing FFmpeg, sending a real-time output to the RTMPS URL and stream key YouTube gives you, and supervising FFmpeg with systemd. First test a short stream, then monitor both the service logs and YouTube’s stream health. A VM and automatic process restarts do not guarantee uninterrupted delivery: network, host, input-file, and YouTube ingest failures still need attention.
How the setup works
Azure supplies the Linux VM; FFmpeg reads your local media and sends it to YouTube Live. YouTube provides the destination URL and stream key for the stream in Live Control Room. The stream key is a credential: do not publish it, put it in a public repository, or expose it in logs.
This guide covers looping a file from an Ubuntu VM. It does not require a separate physical encoder or an inbound port open to the VM just to push video to YouTube. The VM does need working outbound connectivity to YouTube’s ingest endpoint.
1. Create an Ubuntu VM in Azure
- Follow Microsoft’s Linux VM quickstart to create a virtual machine in the Azure portal. Choose an Ubuntu image and region suitable for your deployment.
- Choose a VM size based on the video’s resolution and frame rate, the codecs you plan to use, and whether FFmpeg will encode on the CPU. There is no universal size recommendation for every source and output.
- Plan storage for your source media and confirm that the VM can make outbound connections to YouTube. A public inbound streaming port is not needed for this push workflow.
- Connect to the VM and verify that you can read the directory where the media will live.
Azure VM, disk, region, and data-transfer costs vary with the configuration and location. Check current Azure pricing for your intended deployment before committing; no single cost or SKU applies to every stream.

2. Install FFmpeg and check its build
Install FFmpeg from a trusted package source appropriate for your Ubuntu release. Then inspect the installed build:
ffmpeg -versionFFmpeg’s protocol documentation describes real-time file-to-server streaming with -re, an input file, FLV output, and an RTMP URL. It also documents RTMPS among the RTMP protocol variants, while noting that support can depend on how FFmpeg was built. An rtmps:// address alone does not establish that your installed binary can connect; verify the build and test the actual endpoint you receive from YouTube.
3. Prepare and validate your media
- Use video and audio that you have permission to stream. YouTube’s copyright and platform rules still apply to looping or prerecorded material.
- Check that the file exists, is readable by the account that will run FFmpeg, and contains the audio and video streams you expect. Use
ffprobe, if installed, to inspect a file’s streams and format. - Decide whether to pass through compatible streams or re-encode. If re-encoding, choose codecs, resolution, frame rate, and bitrate for your source and desired output, and compare them with YouTube’s current encoder guidance. The right settings depend on the media and target; there is no universally correct preset.
- Test the file locally before making the service unattended. A file that fails to decode or lacks expected audio will not become a healthy live stream just because systemd restarts FFmpeg.
4. Get the current YouTube RTMPS destination
- Open YouTube Live Control Room and open or schedule the stream.
- Reveal and copy the RTMPS server URL and the stream key shown for that stream. Use the current values from Live Control Room rather than relying on a hard-coded endpoint from an old guide.
- Check how your encoder expects the destination: some take a combined URL and key, while others accept the server URL and stream name separately. YouTube’s API distinguishes the RTMPS ingestion address and stream name fields.
YouTube describes RTMPS as RTMP over TLS/SSL. Its guidance says to use the RTMPS URL from Live Control Room and check the protocol and server if connection setup fails; for a persistent SSL error, it advises trying port 443. See YouTube’s RTMPS help page and the YouTube Live Streams API documentation.

5. Test a short FFmpeg session
Run FFmpeg in the foreground first so you can see errors directly. A looping file command has this general shape:
ffmpeg -re -stream_loop -1 -i /path/to/video.mp4 -c:v libx264 -c:a aac -f flv "$INGEST_URL"This is an illustrative command, not a tested universal recipe. Confirm the installed FFmpeg supports the chosen codecs and looping option. Set INGEST_URL securely to the exact current destination format required by your encoder and YouTube stream; do not substitute the placeholder with a real key in documentation or a shared command history. Adapt encoding settings to the source and YouTube’s current requirements.

For a finite smoke test, remove -stream_loop -1 so the file ends. Confirm that FFmpeg reports progress and that YouTube Live Control Room receives the feed. Check YouTube’s own stream-health indicator before treating the session as ready.
6. Loop media and supervise FFmpeg with systemd
For a single file, -stream_loop -1 requests indefinite looping, while -re reads the file at its native rate rather than sending it as fast as possible. If you need to rotate multiple files, use a playlist-based workflow and validate its syntax against the installed FFmpeg version before relying on it.
Run the process as a dedicated, unprivileged service account. Give that account read access to the media and only the configuration access it needs. A systemd unit can start FFmpeg at boot and restart it after an unexpected process exit. The unit should invoke your tested command and read protected configuration; do not put a real key in a broadly readable unit file. After creating or changing a unit, reload systemd and start it using the unit name you chose:

sudo systemctl daemon-reload
sudo systemctl enable --now youtube-stream.service
sudo systemctl status youtube-stream.serviceReplace youtube-stream.service with your unit’s actual name. A restart policy can recover from an FFmpeg process exit; it cannot fix a bad source file, invalid key, failed network route, VM outage, or stalled remote ingest. Test how the service behaves after a deliberate process stop and inspect the resulting logs before leaving it unattended.
7. Monitor both FFmpeg and YouTube
A running systemd unit only confirms that the process is running, not that viewers receive healthy video. Use both local and platform signals:
- Read recent service output with
sudo journalctl -u youtube-stream.service -n 100 --no-pager; follow new entries withsudo journalctl -u youtube-stream.service -f. - Check FFmpeg’s progress and errors, including whether it is continuing to read and send frames.
- Check YouTube Live Control Room’s stream-health view. YouTube’s API describes active/inactive status, health values such as good, ok, bad, and noData, and configuration issues. These platform-side signals can reveal problems a local process check cannot.
- When delivery fails, distinguish a crashed encoder from an upstream connection problem, VM failure, bad input, or remote ingest stall. Restarting the process is not a diagnosis for every failure.
A community tutorial demonstrates an FFmpeg and systemd watchdog workflow, but its reported freeze behavior and scheduled-restart approach are anecdotal, not a general reliability guarantee: “24/7 YouTube Stream — Setup & Ops Notes”.

Troubleshooting common failures
| Symptom | What to check | Practical next step |
|---|---|---|
| FFmpeg rejects the RTMPS URL or reports a TLS/protocol error | Whether this FFmpeg build supports the required RTMPS transport; whether the URL and protocol match the values in Live Control Room. | Inspect the build, use YouTube’s current RTMPS URL, and follow YouTube’s guidance to check the server/protocol. If an SSL error persists, try port 443 as YouTube advises. |
| YouTube does not receive the stream | The current stream URL and key, their expected combined or separate format, outbound connectivity, and FFmpeg output errors. | Copy the destination again from the active stream in Live Control Room, confirm the encoder’s required format, and review both FFmpeg logs and YouTube stream health. |
| Stream health reports a configuration problem or bad/no data | YouTube’s health details, the video/audio streams in the source, and the encoding choices used by FFmpeg. | Use YouTube’s reported issue to guide changes; validate the source and encoder configuration, then run another short test. |
| FFmpeg exits or systemd repeatedly restarts it | The journal for the first failure, file permissions, path correctness, decode errors, and whether the service account can read its configuration and media. | Fix the underlying error before relying on the restart policy. A restart loop can repeat the same failure without restoring a usable feed. |
| Service is active but viewers do not see a healthy stream | YouTube’s ingest health, not just systemctl status; also check for network loss or a stalled connection. |
Use platform health and FFmpeg progress together to identify whether the fault is local, in transit, or at the ingest side. |
