To loop a prerecorded video on YouTube Live from a Linode server, configure an encoder stream in YouTube Live Control Room, then run FFmpeg with -stream_loop -1 before the video’s -i input. The loop runs until you stop FFmpeg or the connection fails; you must preview and start the live event in YouTube, and monitor it while it runs.
Before you begin
- A verified YouTube channel with live streaming available. YouTube says channels must have no live-streaming restrictions in the previous 90 days, and its help page sets a minimum livestreaming age of 16. Check current eligibility in YouTube’s live-streaming requirements.
- A Linode Compute Instance running Linux, or another Linux host you administer. Linode’s guide outlines creating an account and Compute Instance for a streaming server: Linode streaming-server guidance. It does not establish a specific instance size, encoding benchmark, or current price for this workload.
- FFmpeg installed with the codecs and network protocol support needed for your selected settings.
- A local copy of the prerecorded video, with a known path and working audio/video streams.
- The YouTube ingest URL and stream key for the event. Keep the key private; anyone who has it may be able to broadcast to your stream.
Prepare the Linode host and video
- Create and secure the instance. Follow Linode’s current account and Compute Instance setup instructions. Apply the operating system’s current security updates and use a secure way to connect to the server. The appropriate instance depends on the source media, chosen output settings, and actual encoding capacity; no fixed size is established for this FFmpeg workload.
- Install FFmpeg. Use the package instructions for your Linux distribution and verify that the build includes the encoder and output protocol you intend to use. FFmpeg’s official documentation describes its options and formats at ffmpeg.org/ffmpeg.html.
- Copy the video to the instance. Confirm the file path and inspect its streams before starting. For example, use
ffprobe /path/to/video.mp4if the installed FFmpeg package includes ffprobe. Check that the file has the expected video, audio, frame rate, and resolution; a video without an audio stream may require adjusting the command rather than assuming an audio track exists.
Set up the YouTube Live event
- Open YouTube Studio and go to Create > Go live to enter Live Control Room.
- Create or select an encoder stream/event and configure its visibility and other event details as needed. YouTube documents the encoder workflow in its stream setup instructions.
- Copy the exact server/ingest URL and stream key shown for that stream. Use RTMPS if offered and supported by your FFmpeg build. YouTube describes RTMPS as RTMP secured with TLS/SSL in its ingest protocol guidance.
- Do not publish or share the stream key. Paste the actual URL and key into your local command or a protected configuration, not into a public post or shared script.
Choose settings and run the loop
This command is a template, not a tested Linode configuration. Replace every uppercase placeholder with values suited to the source, frame rate, available server capacity, and YouTube ingest details. The important loop setting is an input option: -stream_loop -1 must come before the corresponding -i. FFmpeg documents this option in its official command-line reference.
ffmpeg -re -stream_loop -1 -i /path/to/video.mp4
-c:v libx264 -preset veryfast -b:v VIDEO_BITRATE
-maxrate VIDEO_BITRATE -bufsize VIDEO_BUFFER
-pix_fmt yuv420p -g KEYFRAME_INTERVAL
-c:a aac -b:a 128k -f flv 'RTMPS_INGEST_URL/STREAM_KEY'What to set in the template
-rereads the file at its native playback rate rather than sending it as fast as possible.VIDEO_BITRATEandVIDEO_BUFFERare placeholders, not literal FFmpeg values. Select a compatible bitrate for the resolution and frame rate, then set the buffer in a form accepted by FFmpeg (for example, a value with a unit suffix). YouTube’s current encoder settings give its recommended configuration by video format and resolution; follow that guidance rather than assuming one bitrate fits every file.-g KEYFRAME_INTERVALsets the GOP/keyframe interval in frames. YouTube recommends a two-second interval and says not to exceed four seconds. Convert the interval to frames for your output frame rate—for example, a two-second interval at 30 fps corresponds to 60 frames. YouTube’s published guidance also specifies constant bitrate (CBR); use a configuration that actually maintains CBR rather than treating a target bitrate as a guarantee.-c:v libx264encodes H.264 video; confirm the installed FFmpeg build supports it. YouTube also documents other ingest-compatible video codecs and frame rates, but this example uses H.264.-c:a aac -b:a 128kencodes audio as AAC at the example bitrate. Confirm that the source has audio and that this setting is appropriate for the content.-f flvselects the streaming output container used for RTMP/RTMPS ingest. Replace the quoted output with the exact ingest URL and key format provided in Live Control Room; do not copy a placeholder as a real credential.
Match output resolution and frame rate to what the source and host can sustain. YouTube’s encoder guidance covers supported settings, including frame rates up to 60 fps, H.264/H.265/HEVC/AV1 video options, AAC or MP3 audio, and CBR. A Linode instance may not encode every resolution in real time; confirm the machine can keep up before relying on a long broadcast.
Preview, start, and monitor the broadcast
- Run the completed FFmpeg command in a terminal session that will remain active, or manage it with an appropriate persistent service/session method. Keep the logs available so connection or encoder errors can be diagnosed.
- Wait for YouTube Live Control Room to receive the encoder feed, then check the preview for picture, sound, correct framing, and playback motion before starting the event.
- Start the event in Live Control Room. Monitor YouTube’s stream health and the FFmpeg output, particularly after startup and after any network interruption. YouTube’s stream health guidance explains the status indicators.
- Check the Linode host’s outbound throughput. YouTube recommends approximately 20% upload bandwidth headroom above the total stream bitrate; the server’s actual network path must sustain that margin rather than only matching the nominal encoder bitrate. See YouTube’s recommended encoder settings.
Stop the stream and plan for archiving
End the broadcast in Live Control Room and stop the FFmpeg process on the server. YouTube’s help page says streams under 12 hours are automatically archived; that statement does not establish automatic archiving for an indefinitely long broadcast. For longer runs, plan separate sessions or verify the archive behavior for the specific event in YouTube’s current encoder streaming guidance.

Linode versus a computer you already control
| Consideration | Linode Compute Instance | Your own computer |
|---|---|---|
| Availability | Runs remotely, so your home computer need not stay on; availability still depends on the instance and its network. | Requires the computer, FFmpeg process, and local network to remain available. |
| Media access | The file must be transferred to and kept available on the instance. | The file can remain on local storage, provided the machine can read it throughout playback. |
| Encoding capacity | Depends on the selected instance and workload; no specific size or performance is established here. | Depends on the computer’s encoding capability and whether it can sustain the chosen settings. |
| Network | Depends on the instance’s outbound connectivity and available throughput. | Depends on the local connection and its sustained upload capacity. |
| Administration and cost | Requires remote-host setup and maintenance; current workload-specific price is not stated. | Uses equipment and service you already control, but requires local power, connectivity, and administration. |
Neither option is universally cheaper or better. Compare current hosting costs and the reliability and encoding capacity you actually need; the Linode guide does not provide a workload-specific benchmark or price comparison.
Troubleshooting common failures
- YouTube does not receive a signal: check that the RTMPS URL and stream key match the active encoder stream, that the key has not been revoked or mistyped, and that FFmpeg supports the required protocol. Review the FFmpeg error output and YouTube’s stream-health status.
- The stream connects but video is black or incorrect: inspect the input with ffprobe, verify the path and video stream, and confirm the command is encoding the intended file. Check the preview before going live.
- There is no sound: verify that the file contains an audio stream. If it does not, remove or change the audio mapping/encoding assumptions rather than expecting AAC encoding to create source audio. If sound exists but is silent or distorted, inspect the selected audio stream and test a representative segment.
- FFmpeg cannot keep up or the stream stutters: reduce output resolution, frame rate, or encoding load; test a faster preset if using software encoding; and check the instance’s actual CPU and network capacity. Preserve YouTube’s recommended keyframe interval and network headroom where possible.
- Connection drops interrupt the broadcast: inspect host connectivity and FFmpeg logs, then reconnect using the same active event credentials if YouTube still accepts them. A single FFmpeg command does not itself guarantee automatic recovery after a disconnect.
- The video does not loop: confirm
-stream_loop -1appears before the input’s-iand that the process has not exited because of a file, codec, or output error.
Copyright and channel-policy checks
Having a video file does not by itself establish the right to broadcast it. Before streaming, confirm that you have permission for the footage, music, narration, and any other included material, including rights for live use. YouTube’s copyright and channel rules apply to live streams as well as uploads; review the current live-streaming requirements and YouTube policy pages for your content and channel status. Repeating a prerecorded video also does not guarantee eligibility for monetization: YouTube evaluates channels under its monetization policies, including reused-content rules, independently of the streaming setup.
