The loop can repeat the file, but it cannot guarantee an uninterrupted broadcast: you still need adequate upload capacity, a tested stream, monitoring, and a plan for failures.
Before you start
- An Ubuntu machine or server that can stay online, with access to the video file and a stable internet connection.
- FFmpeg installed for your Ubuntu release. Installation commands and option availability vary by Ubuntu release and FFmpeg build, so check the package and build you actually use rather than relying on an unverified version-specific command.
- A YouTube channel eligible to stream live. YouTube requires channel verification and no live-stream restriction in the previous 90 days. First-time live activation may take up to 24 hours. YouTube Help: Get started with live streaming.
- A video file with usable video and audio streams, if audio is intended.
Enable YouTube Live and get the ingest details
- Sign in to YouTube Studio and open Live Control Room.
- Create a stream or select the stream setup you intend to use. Copy the ingest URL and its matching stream key from the current setup.
- Keep the stream key private. Treat it like a password: do not put it in a public script, repository, screenshot, or article, and reset it in YouTube Studio if it is exposed. See YouTube Help: Manage your stream key.
- If this is the channel’s first live stream, allow up to 24 hours for activation before troubleshooting FFmpeg.
Choose a format and bitrate your connection can sustain
YouTube’s encoder guidance lists H.264 video, CBR, AAC or MP3 audio, and a recommended keyframe interval of 2 seconds, not exceeding 4 seconds. YouTube recommends RTMPS for encrypted delivery to its servers. Use the ingest URL shown for your stream and verify that your FFmpeg build supports the chosen protocol. Current encoder settings are documented in YouTube Help: Encoder settings for live streaming.
| H.264 format | YouTube recommended video bitrate |
|---|---|
| 480p at 30 fps | 5 Mbps |
| 1080p at 30 fps | 10 Mbps |
| 1080p at 60 fps | 17 Mbps |
These are YouTube recommendations, not a promise that the source or your connection will produce a particular result. Other supported codec recommendations differ; consult YouTube’s current settings table for your selected codec and format. YouTube also recommends 20% upload headroom. That margin is important because other devices and applications may share the connection; YouTube cautions that the total stream bitrate cannot exceed available upload bandwidth. Test sustained upload under representative conditions and account for other traffic before choosing a bitrate. See encoder settings and YouTube Help: Streaming tips.
Publish a looping file with FFmpeg
The following is an illustrative command, not a tested recipe. It combines FFmpeg’s real-time input pacing and input looping with RTMP-style publishing. It assumes a 30 fps output, making a 60-frame GOP approximately two seconds. Adjust the GOP to match the actual output frame rate, and choose a bitrate appropriate for the selected resolution and measured upload capacity.

- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
ffmpeg -re -stream_loop -1 -i video.mp4
-c:v libx264 -preset veryfast
-b:v 4500k -maxrate 4500k -bufsize 9000k -g 60
-c:a aac -b:a 128k
-f flv "$YOUTUBE_RTMPS_URL/$YOUTUBE_STREAM_KEY"Set YOUTUBE_RTMPS_URL to the ingest URL supplied by YouTube and YOUTUBE_STREAM_KEY to the matching key. Confirm the exact RTMPS URL format expected for your current stream setup and FFmpeg build; do not assume every key or endpoint uses an identical URL shape. Keep real credentials out of shell history and logs as well as public files. FFmpeg documents real-time RTMP publishing in its protocol documentation and input looping in its main manual.
In this example, -re reads input at its native rate rather than sending it as fast as possible; -stream_loop -1 requests indefinite input looping; -c:v libx264 encodes H.264; -b:v and -maxrate set the target and maximum video rate; -bufsize sets the rate-control buffer; -g sets the GOP length in frames; -c:a aac and -b:a set AAC audio and its bitrate; and -f flv selects the output container used by this RTMP publishing pattern. The example’s bitrate values are illustrative, not a universal YouTube setting. Its filters, input compatibility, codec availability, looping behavior, and RTMPS handling need to be checked on your actual media and installation.

Verify the live output before leaving it running
- Start the command and watch FFmpeg’s output for input, encoding, or connection errors.
- Open the stream in YouTube Live Control Room. Confirm that the preview appears and that video and audio are present as intended.
- Check YouTube’s stream health indicators and verify that the selected resolution and frame rate are being received. Test the complete path before relying on the broadcast, as recommended in YouTube’s streaming tips.
- During operation, monitor both the encoder process and YouTube’s stream health. A process supervisor can restart an exited process, but it cannot correct a bad key, unsupported media, insufficient upload capacity, a channel restriction, or an ongoing network outage.
Plan for long-running operation and platform limits
A file loop only repeats that file. It does not provide a playlist scheduler, alternate source, alerting, or a repair for a damaged or incompatible media file. Decide separately how you will observe failures and respond to them. Restarting FFmpeg blindly may simply repeat the same failure or create a new stream session that needs attention in Live Control Room.
YouTube says streams under 12 hours are automatically archived. Do not assume a broadcast that runs longer than 12 hours will be archived as one complete video; plan stream-session management and check current YouTube behavior if a complete archive matters.

Common problems and what to check
| Symptom | Likely checks and next step |
|---|---|
| YouTube does not show an incoming stream | Confirm live streaming is enabled, use the current ingest URL and matching key, and verify the endpoint format and RTMPS support in the installed FFmpeg build. |
| FFmpeg exits immediately or reports input errors | Check the file path and permissions, then confirm the file contains decodable video and any expected audio stream. Test the media independently before starting the live output. |
| Stream health is poor, unstable, or drops | Lower resolution, frame rate, or bitrate until the connection sustains the stream with YouTube’s recommended 20% upload headroom. Retest with other household or server traffic included. |
| Video arrives but audio does not | Check that the input has an audio stream and that the audio codec and mapping are compatible with the output. The illustrative command assumes audio is present. |
| The process restarts but the broadcast still fails | A restart only helps when FFmpeg exited and the underlying cause is transient. Check credentials, media compatibility, channel eligibility, available upload bandwidth, and network status before relying on repeated restarts. |
| The archive is incomplete or split | Review the stream’s duration and session handling. YouTube’s automatic archive statement applies to streams under 12 hours; do not presume a longer session produces one complete archive. |
