To loop a prerecorded video on YouTube Live from a Raspberry Pi, use FFmpeg’s -stream_loop -1 input option, pace the file with -re, and send it to the RTMPS server URL and stream key shown in YouTube Studio. The simplest command uses stream copy, so it avoids video encoding on the Pi—but it works only if the source’s codecs and other stream properties are compatible. Test the exact file, Pi, network and settings in YouTube Live Control Room before relying on a long broadcast.
What you need before starting
- A Raspberry Pi with FFmpeg installed and a stable wired or wireless internet connection.
- A prerecorded video file stored on the Pi, with audio if your broadcast needs it.
- A YouTube channel with live streaming available and a stream created in YouTube Studio.
- The stream’s server URL and private stream key. Treat the key like a password: anyone with it may be able to send video to your stream.
Check the installed FFmpeg build before using an example from another system: run ffmpeg -version. FFmpeg options and codec availability depend on the installed version and build. Its documentation distinguishes stream copying from encoding. FFmpeg documentation.
Create a YouTube Live stream and get its key
- In YouTube Studio, select Create → Go Live.
- Create or select the stream. Copy the server URL and stream key provided for the encoder. Do not publish or share the key.
- Leave Live Control Room open so you can check the incoming preview and stream health after FFmpeg connects.
YouTube’s workflow is to enter the server URL and key in the encoder, start the encoder, and verify the preview in Live Control Room; depending on the scheduled-stream workflow, you may also need to start the broadcast there. YouTube Help: Create a live stream with an encoder.
Check the video before looping it
Find the file’s streams and format with ffprobe, which is typically installed alongside FFmpeg:

ffprobe -hide_banner "input.mp4"
Look at the video and audio codec, resolution, frame rate, pixel format, and whether the file has more than one audio track. Stream copying does not convert these properties. It simply passes the existing streams through, so the codecs and stream details must be suitable for the output format and YouTube ingest. If they are not, use a compatible source file or transcode it, then test that version.
Run the loop with FFmpeg
Try stream copy first
Replace input.mp4 with the local file path and replace the final placeholder with the YouTube RTMPS ingest URL and stream key. Keep the URL and key private; avoid saving a command containing the key in a public script or shared terminal history.

Put -stream_loop -1 before the corresponding -i; -1 requests an indefinite loop. -re reads the file at its native media rate instead of sending it as quickly as the Pi can read it. The -c:v copy and -c:a copy options avoid video and audio re-encoding. For a source with no audio stream, omit -c:a copy if FFmpeg reports that the requested audio stream does not exist. FFmpeg documents these options and their behavior; verify them against the version installed on your Pi. FFmpeg documentation.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsThis is a starting point, not a guarantee that every MP4 can be sent this way. Stream copy may fail or yield unsuitable output if the source codecs, pixel format, timestamps, audio layout, or container assumptions are incompatible with the FLV output and YouTube ingest. If the command fails, use the troubleshooting section below rather than assuming the loop option is the problem.
Transcode only when necessary
If the source is incompatible or you need to control output resolution and bitrate, ask FFmpeg to encode it. For example, this H.264/AAC template targets 720p at 30 fps and 8 Mbps video. It is a starting configuration, not a promise that a particular Pi can encode it in real time; test CPU load and stream health on your exact board.

ffmpeg -re -stream_loop -1 -i "input.mp4" -vf "scale=-2:720,fps=30" -c:v libx264 -preset veryfast -b:v 8M -maxrate 8M -bufsize 16M -g 60 -keyint_min 60 -sc_threshold 0 -c:a aac -b:a 128k -ar 44100 -f flv "<YouTube RTMPS ingest URL>/<STREAM_KEY>"
Here, -g 60 sets a 60-frame GOP, or two seconds at 30 fps; -keyint_min 60 sets the minimum keyframe interval. The scale expression preserves aspect ratio while setting the height to 720 pixels. Adjust the frame rate, GOP and bitrate together if you choose a different output frame rate. If your FFmpeg build lacks libx264, this command will not work as written; check available encoders with ffmpeg -encoders.

YouTube’s published H.264 bitrate recommendations, accessed in 2026, are:
| Output | Minimum video bitrate | Recommended video bitrate |
|---|---|---|
| 720p at 30 fps | 3 Mbps | 8 Mbps |
| 1080p at 30 fps | 5 Mbps | 14 Mbps |
| 1080p at 60 fps | 6 Mbps | 17 Mbps |
These are YouTube recommendations, not guarantees that a Pi or internet connection can sustain a particular output. Choose a conservative resolution and bitrate based on measured upload capacity, then test with representative sound and motion. YouTube recommends a speed test and monitoring stream health. YouTube encoder settings.
Verify the live preview and test a full loop
- Start FFmpeg and watch its output for connection or encoding errors.
- In YouTube Live Control Room, confirm that the preview appears and that stream health does not report a problem.
- Check both video motion and audio. Let the file reach its end and confirm it starts again; inspect the transition for a gap, frozen frame, or audio discontinuity.
- Keep a representative test running long enough to expose network instability, Pi overheating or throttling, and file-specific issues before depending on it for an event.
- When ready, use the Live Control Room controls for the broadcast workflow you selected. Do not assume connecting FFmpeg always starts the public broadcast automatically.
Raspberry Pi performance varies by model and task. Stream copy avoids video re-encoding, but transcoding adds compute demand. Raspberry Pi’s camera documentation is not a benchmark for FFmpeg file streaming, so it cannot establish a universal performance guarantee for every Pi. Raspberry Pi Picamera2 manual.

Copyright, reused content and long broadcasts
Use media you have the right to broadcast
Looping a file does not grant permission to use its footage, music, narration, or other protected material. Before going live, check the rights and licenses for every part of the recording. A live broadcast can be interrupted or restricted if its content violates YouTube’s rules or a rights holder’s claim. For a practical preflight, use the copyright safety checklist.
Consider originality and monetization separately
A technically successful continuous stream does not itself establish eligibility for monetization. Repeating prerecorded material may be considered repetitive or reused depending on the channel and content; assess YouTube’s current monetization policies rather than assuming that a live format changes the rules. The loop command controls playback, not policy eligibility.
Plan the broadcast lifecycle
YouTube states that streams under 12 hours are automatically archived. Do not assume the same archival outcome for streams longer than 12 hours based on that statement alone; check current channel behavior and plan how you will end or manage a longer broadcast. YouTube Help: live stream workflow.
Common problems and fixes
| Symptom | Likely cause | What to check or change |
|---|---|---|
| FFmpeg reports an error opening the output or cannot connect | Incorrect server URL or key, unavailable ingest endpoint, or network restriction | Copy the current URL and key from YouTube Studio, keep the key intact, check network access, and try the RTMPS endpoint supplied by YouTube. |
| Unsupported codec, muxing, or stream error | The source streams are not compatible with the chosen output/container | Inspect the file with ffprobe. Try a compatible source or transcode to an ingest-compatible codec and test again. |
| FFmpeg says there is no audio stream | The command requests audio copy from a silent file | Remove -c:a copy; if you need audio, add a suitable audio source or use a file that contains audio. |
| Preview stutters, drops frames, or reports poor health | Bitrate exceeds stable upload capacity, network varies, or Pi is overloaded during encoding | Check stream health and upload capacity; lower resolution or bitrate. If transcoding, reduce the encoding workload or use stream copy when the source is compatible. |
| Stream connects but video or sound is wrong | Unexpected frame rate, pixel format, audio track, or source timestamps | Inspect with ffprobe, watch a complete test including the loop point, and create a corrected source or explicit transcode. |
| The video plays once and stops | The loop option is missing, misspelled, or placed after the input it should affect | Use -stream_loop -1 before the relevant -i and confirm the installed FFmpeg accepts it. |
| FFmpeg stops when the Pi shuts down or loses power | The encoder is running locally on the Pi | Use stable power and configure a supervised process if keeping the DIY setup; a local encoder cannot continue when its host is off. |
RTMPS or HLS for this setup?
For a basic FFmpeg-to-YouTube setup, RTMPS is the simpler default when YouTube Studio provides it. YouTube also supports HLS ingest, but says HLS has higher latency than RTMP because it sends video in segments. HLS requires TS segments of 1–4 seconds, a rolling playlist with no more than five outstanding segments, and HTTPS POST/PUT requests. That extra packaging and playlist handling make HLS a less direct fit for the simple command above. YouTube HLS ingest guidance.

The first day is free with no card, one free day per account. Monthly billing is $9.99 per month. Learn about StreamNeo, then start the free day.
Cost and capacity considerations
A Raspberry Pi is only one part of the DIY cost: account for storage for the video, reliable power, internet service, and the electricity and maintenance involved in keeping the board online. If you need to estimate transfer time before uploading a large file to a cloud service, use the upload-time calculator. To compare recurring computer and cloud costs, use the cloud vs PC cost calculator. A Pi model is not prescribed by this workflow; test the exact model and encoding workload rather than buying a board on the assumption that all models perform alike.
