Use -re to read the file at real-time pace. The examples below show a starting point for a video that already contains its sound, plus the decisions to make when you need to combine separate audio and visuals.
Before you start: check channel access and prepare your stream
- Install FFmpeg and check the version with
ffmpeg -version. FFmpeg documentation is regenerated nightly, so if an option behaves differently on your system, compare it with the localffmpeg -h fulloutput. - YouTube says live streaming requires a verified channel, no live-streaming restrictions in the previous 90 days, and a streamer who is at least 16 years old. See YouTube’s live-streaming requirements.
- In YouTube Studio’s Live Control Room, create or schedule a stream and select the encoder workflow. Copy the server address and stream key shown for that stream; use the current values shown in your account rather than assuming a fixed ingest address.
- Keep the stream key private. Don’t commit it to a script or share it in logs, screenshots or chat. The commands below use placeholders; replace them locally with the server address and key from the Live Control Room.
- Use audio and visuals you have permission to stream. This guide does not establish YouTube’s copyright or monetization treatment of sleep-sound streams; check the rights attached to your specific recordings and YouTube’s applicable policies.
Loop a video file that already contains the sleep sounds
If one file contains both the intended visual and audio, this is the simplest setup. The command explicitly selects the first video and audio streams, loops the input indefinitely and reads it at real-time pace.
ffmpeg -stream_loop -1 -re -i "sleep-scene.mp4"
-map 0:v:0 -map 0:a:0
-c:v libx264 -pix_fmt yuv420p
-c:a aac -b:a 128k -ar 44100
-g 60 -f flv "rtmps://YOUR_INGEST_ENDPOINT/YOUR_STREAM_KEY"Replace the filename and RTMPS address with your own. FFmpeg options generally apply to the next input or output, so keep -stream_loop -1 and -re before the input they configure. The example transcodes video and audio; it is illustrative, not a tested universal script. Its -g 60 is a two-second GOP only if the output is 30 fps. If your output frame rate differs, choose the GOP accordingly.
Protect the stream key in a shell variable
For a shell session, you can keep the key out of the command text you save in a script by placing the full URL in an environment variable. Restrict access to the shell history and environment where appropriate; environment variables are not a substitute for a secret manager on a shared system.

-g 60 -f flv "$YOUTUBE_RTMPS_URL"Choose stream copy or transcoding
Use transcoding when the source needs a different codec, frame size, frame rate, audio format or filter. It gives you conversion and filtering options, but uses processing power and can affect quality. The earlier command is a transcoding example.
Stream copy avoids decoding and re-encoding, preserving the encoded streams without an additional quality loss from encoding. It is efficient, but only works when the source streams suit the output container and YouTube’s ingestion settings; it cannot apply filters. If you want to try it with a compatible source, replace the codec options with:

-c copyFor example, keep the loop, pacing, input, explicit maps and RTMPS output from the first command, but use -c copy instead of the -c:v and -c:a encoder options. If YouTube does not accept the resulting stream, check the source codecs and output compatibility, then transcode to supported settings.
Match the output to YouTube’s current encoder guidance
YouTube’s live encoder settings guidance, accessed October 3, 2026, lists the following requirements and recommendations. The page’s bitrate figures are ingestion recommendations, not guarantees or a universal bitrate for every source and connection.

| Setting | YouTube guidance | What to check in your stream |
|---|---|---|
| Ingest protocol | RTMP or RTMPS; YouTube recommends RTMPS for encrypted delivery into and through Google’s servers. | Use the RTMPS address supplied for your stream when available. |
| Video codec | H.264, H.265 (HEVC) or AV1. | Check the codec produced by your chosen encoder or preserved by stream copy. |
| Frame rate | Up to 60 fps. | Use an output frame rate supported by the Live Control Room and ensure GOP length matches it. |
| Keyframe interval | Recommended: 2 seconds; do not exceed 4 seconds. | The sample’s -g 60 is two seconds only at 30 fps. Set GOP and frame rate together. |
| Audio codec | AAC or MP3. 5.1 audio over RTMP/RTMPS is supported only for AAC. | The sample converts audio to AAC. |
| Bitrate mode | CBR. | The sample does not explicitly set a video bitrate or CBR mode. Consult YouTube’s current resolution, frame-rate and codec table, then set options that suit your chosen output and reliable upload capacity. |
| Audio sample rate | 44.1 kHz stereo; 48 kHz for 5.1. | The sample requests 44.1 kHz. Check the source channel layout and select settings for the intended output. |
| Stereo audio bitrate | 128 Kbps. | The sample requests 128k for audio. |
For H.264, the page lists 1080p30 at 5 Mbps minimum and 14 Mbps recommended, and 720p30 at 3 Mbps minimum and 8 Mbps recommended. YouTube’s AV1 and H.265 rows give different values. Use the table for your codec, resolution and frame rate instead of treating one figure as right for every stream.
Use separate audio and visual files
If your sleep sounds are in an audio file and you want a separate visual, the inputs must both loop and the output must include a compatible video stream. The exact command depends on the files and desired visual treatment. A static image, a gently animated video and a generated visual are different setups; this guide does not present one untested command as universally suitable for all of them.

- Please Note: To reach 10Gbps speed, keep the cable under 3.3 ft. For USB A Male to USB C adapters, try flipping the USB C connector. USB C Male to USB A adapters support bidirectional 10Gbps transfer within 3.3 ft
- For a visual video file that already contains the desired look, map the audio and video streams you intend to use. If the audio file is separate, loop that input too, and verify the output duration and synchronization before going live.
- For a static image paired with audio, the image must be supplied as video output rather than relying on an audio-only stream. Choose a frame rate and compatible encoding settings, and test the resulting stream in the Live Control Room.
- For an audio-only file, do not assume a standalone audio stream will be accepted by your chosen YouTube live workflow. Provide a compatible visual stream unless you have verified that the specific destination accepts the stream shape you plan to send.
An FFmpeg-user discussion from 2020 includes an individual suggestion about silent audio with a static-image stream, but it is dated community advice, not proof of a universal YouTube requirement or an official sleep-sounds workflow: the discussion.
Preflight the stream, then monitor it while live
- Confirm that the media plays locally and contains the intended audio and visual tracks. Use explicit
-mapoptions when the input has multiple tracks so an unintended track is not selected. - Check the output settings against the current Live Control Room options and YouTube’s encoder guidance. Confirm the codec, resolution, frame rate, keyframe interval, bitrate mode, audio codec and sample rate.
- Run a private or unlisted test stream if appropriate for your channel, using representative audio and visual movement. YouTube recommends a preflight test and an upload-speed check.
- Watch stream health in the Live Control Room during the test and the live session. Monitor FFmpeg’s output and available upstream bandwidth as well.
- Confirm the loop returns to the start cleanly, with no unintended gap or abrupt change that makes the sound unsuitable for your stream.
Troubleshoot common looping and live-stream problems
| Symptom | Likely checks | What to do |
|---|---|---|
| The file plays once and stops. | Check whether -stream_loop -1 is before the input’s -i. |
Move the option before the relevant input. FFmpeg options generally apply to the next input or output. |
| The stream runs too quickly or YouTube reports unstable delivery. | Check whether a file input is being read at real-time pace and whether upload capacity is reliable. | Use -re on file input for real-time pacing and test upload speed. FFmpeg cautions against low read rates on actual capture devices or live streams, where packets may be lost. |
| YouTube reports an unsupported or unhealthy stream. | Check the Live Control Room diagnostics, codec, container compatibility, bitrate mode, resolution, frame rate, keyframe interval and audio settings. | Compare the actual output with YouTube’s current guidance; change the settings or transcode if the source is incompatible. |
| The picture or sound is wrong or missing. | Check the input’s available streams and the -map selections. |
Map the intended audio and video streams explicitly. If the source lacks a visual, supply a compatible visual source for the chosen live workflow. |
| Encoding stalls or the stream disconnects. | Review FFmpeg logs, CPU headroom, upstream bandwidth, YouTube’s stream-health diagnostics, timestamps and whether the input loop returns cleanly. | Reduce processing load or output demands if resources are constrained, correct timestamp or compatibility issues shown in logs, and test again. These are diagnostic checks, not a guarantee that any one cause applies. |

Frequently Asked Questions
Does FFmpeg keep looping if my computer is shut down?
No. A local FFmpeg process needs the computer running; for a stream that continues without a home computer, use a cloud-based workflow.
Can I use any sleep-sound recording?
Only use recordings whose rights permit your intended YouTube livestream. This guide does not determine the licensing terms for a particular recording.
