FFmpeg sends the file repeatedly at real-time speed; YouTube still controls whether and when the event goes live, and looping does not guarantee an indefinitely running event or archive.
What you need before you start
- A YouTube channel with access to YouTube Live and a live event created or scheduled in YouTube Studio.
- A Linux DigitalOcean Droplet with FFmpeg installed, enough CPU for the chosen encoding settings, and a stable network connection.
- A video file available on the Droplet, with audio if needed. Test the file and intended output settings before relying on a long broadcast.
- The current server URL and stream key shown for that specific YouTube event. Keep the key private: someone who obtains it may be able to send video to your event.
A Droplet is the Linux virtual machine that runs FFmpeg. For direct file-to-YouTube streaming, you do not need a separate streaming server. DigitalOcean also offers an SRS Marketplace image with streaming-server and FFmpeg features, but that is an optional, different setup: DigitalOcean SRS Marketplace image.
Create the YouTube Live event and get its ingest details
- In YouTube Studio, select Create → Go Live.
- Choose the Stream tab to set up a new event, or use Manage to schedule one.
- Copy the server URL and stream key for the event. Use the current values YouTube displays; do not assume a sample or previously used endpoint is correct.
- Keep the key private. Do not paste it into a public command log, screenshot, or script repository.
YouTube recommends RTMPS, its secure extension to RTMP. Use the event’s provided secure ingest address where available. YouTube’s ingest guidance specifies the rtmps scheme and port 443, and the hostname must be correct for TLS SNI. See YouTube’s encoder settings and bitrates, YouTube ingestion protocols, and YouTube RTMPS ingestion.
Prepare the Droplet and video
Install and verify FFmpeg
Install FFmpeg using the package source appropriate to your Linux distribution, then check that the installed build includes the codecs and RTMPS support you intend to use. Package names and available codec support differ by distribution and build, so verify the actual binary rather than assuming a particular command will work everywhere. FFmpeg’s protocol documentation describes RTMPS as RTMP over a secure SSL connection: FFmpeg RTMPS protocol documentation.

Put the file somewhere the process can read it
Use an absolute path to a local file where possible, and ensure the account running FFmpeg can read it. If the file is remote, confirm that the Droplet can reach it reliably for the whole broadcast. Before going live, inspect the file and run a short test with representative movement and audio. YouTube recommends testing stream health before a broadcast.
Choose YouTube-compatible output settings
YouTube’s current encoder guide lists H.264, H.265/HEVC, and AV1 video; frame rates up to 60 fps; constant bitrate (CBR); and a recommended two-second keyframe interval that should not exceed four seconds. AAC or MP3 audio is supported for RTMP/RTMPS. Choose resolution and bitrate from the current YouTube table rather than copying a bitrate from an unrelated example. The Droplet must have enough CPU and network capacity for the selected output; no universal Droplet size or performance figure is established here.

- Resolution and frame rate: match the intended presentation and choose a bitrate from YouTube’s current encoder guide.
- Bitrate: use CBR and set the video bitrate and rate-control buffer deliberately. A larger resolution or frame rate generally requires a higher bitrate, but the correct value depends on YouTube’s current table and the Droplet’s tested capacity.
- Keyframes: target a two-second interval and do not exceed four seconds. With a fixed frame rate, the GOP length in frames is approximately twice the frames per second for a two-second interval; for example, 30 fps uses 60 frames.
- Audio: AAC is a practical choice for the example below. Set a bitrate appropriate to the content and verify that audio is present in the YouTube preview.
These requirements and recommendations can change; check YouTube’s encoder settings when configuring a new stream.

The output options encode H.264 video and AAC audio, then send the stream in FLV format to the RTMPS address.
Set GOP_FRAMES to produce a two-second keyframe interval at your chosen frame rate. For 30 fps, that is 60 frames; use a different value for other frame rates.

DigitalOcean’s tutorial documents the -stream_loop -1 pattern and -re pacing; see DigitalOcean’s FFmpeg live-streaming tutorial. FFmpeg option placement matters: input options belong before the relevant -i. Confirm syntax and capabilities against your installed FFmpeg build; FFmpeg’s documentation is at FFmpeg command-line documentation.
When stream-copying may be appropriate
If the file already has compatible codecs, timestamps, and characteristics for YouTube ingest, stream-copying may reduce Droplet encoding load. It is not established as suitable for every file or ingest condition. Test it with the actual source and event before depending on it. Re-encoding offers more control over output settings but consumes CPU.

Start FFmpeg, verify the preview, and start the event
- Run the command in a session that will remain active on the Droplet. For a long stream, arrange process supervision and server monitoring so that you notice an exit or resource problem; an FFmpeg loop by itself does not restart a failed process.
- Watch FFmpeg’s output for connection failures, timestamp errors, encoder overload, and a nonzero exit status.
- Open the event in YouTube Live Control Room and verify the preview, audio, and stream health.
- For scheduled-stream workflows, follow YouTube’s event controls: a connected encoder may only make the preview available, and you may still need to select Go live in Live Control Room.
- Check the file boundary. The loop repeats the video, but it does not smooth a hard visual cut or guarantee seamless audio at the join.
YouTube recommends a test using movement and audio representative of the real stream, and monitoring stream health and encoder warnings while live. Its live-stream instructions say streams under 12 hours are automatically archived; this is not a promise that one event can run indefinitely or that longer sessions will be archived. Plan a session and restart strategy around YouTube’s current behavior: YouTube live-stream instructions.
Troubleshoot common failures
| Symptom | Likely cause | What to check or do |
|---|---|---|
| YouTube does not receive a signal | Wrong event URL or key, an incorrect RTMPS address, network blockage, or unsupported RTMPS in the FFmpeg build. | Copy the current event URL and key again, check the rtmps scheme and port 443, confirm the hostname and path, and verify FFmpeg’s protocol support. |
| FFmpeg connects, but the event is not publicly live | The event may be scheduled and waiting for the creator to start it. | Check the preview and health in Live Control Room, then use its event controls if YouTube asks you to select Go live. |
| Video is rejected or stream health warns about settings | Output codec, frame rate, bitrate, keyframe interval, or audio format may not match YouTube’s current guidance. | Compare actual output with YouTube’s encoder guide; verify H.264/HEVC/AV1, a supported frame rate up to 60 fps, CBR, keyframe interval, and supported audio. |
| Video stutters or FFmpeg reports encoding overload | The Droplet may not be able to encode the chosen settings in real time. | Check CPU load and FFmpeg logs. Test a lower resolution/frame rate or a less demanding encoding configuration, or use stream-copying only if the source is compatible and has been tested. |
| The stream stops after running successfully | FFmpeg exited, the Droplet or network had an interruption, or YouTube ended the event. | Check the process exit status and server/network logs, restart the encoder and event as needed, and verify current YouTube duration behavior. The input loop does not itself reconnect or relaunch FFmpeg. |
| A noticeable click or jump occurs at each repeat | The file’s start and end are not seamless. | Edit or prepare a version with a clean join, then test the transition in a private or unlisted event before using it for a public broadcast. |
Copyright and YouTube policy still apply
Using FFmpeg to loop a file does not grant permission to stream its music, footage, artwork, or other protected material. Use content you own or have permission to broadcast, and check YouTube’s applicable copyright and monetization rules. Repeated playback also does not by itself establish eligibility for monetization; assess the channel and content against YouTube’s current policies. Keep the stream key private and review the event’s visibility and audience settings before starting.
Or let it run in the cloud
If you want a YouTube-only way to keep uploaded videos playing without maintaining a Droplet and FFmpeg process, StreamNeo runs the loop from the cloud.
