To loop a Tibetan singing bowl recording on YouTube Live, use FFmpeg’s -stream_loop -1 before the audio input, pair it with a visual input, and send the encoded output to the RTMPS address and stream key shown in YouTube Live Control Room. Treat the command below as a starting pattern: test it with your exact files and channel settings before relying on it for a long broadcast.
The loop flag repeats an input; it does not guarantee that the join between the end and start of the recording will sound smooth, or that YouTube will retain an unusually long stream. You also need permission for the actual recording, not just a belief that the underlying tones are traditional or unowned.
Prepare and clear the audio recording
Start with the exact audio file you plan to use. Check that it opens, plays from beginning to end, and has the expected duration. A long quiet opening or an abrupt ending can be more noticeable in a repeated meditation track than in a varied programme. Listen at a sensible volume, including the first and last moments, before building the stream around it.
The subject of a recording does not establish its rights. The sound recording may be protected even where the instrument or practice is traditional. Use a recording you made yourself or one whose licence explicitly permits the intended live broadcast and any archive you expect to keep. YouTube’s livestream terms and conditions put responsibility for necessary rights, including music licensing rights, on the content provider. Keep a copy of the permission or licence and check its scope; do not assume that permission for personal listening also covers a public stream.
Inspect the file’s properties and verify that FFmpeg can read it. A command-line probe such as ffprobe -hide_banner bowl-audio.mp3 can help show the streams and duration, if ffprobe is installed alongside FFmpeg. If the file has multiple audio streams, note which one contains the intended recording. In the command later in this guide, 0:a:0 selects the first audio stream from the first input; change that mapping if your file is different.
It is worth deciding whether to loop an audio file separately from the visuals or to make one video file containing both. Separate inputs give you explicit control over which audio and video streams are mapped, but their durations and loop points may not line up. A pre-edited video can make the mapping simpler while moving the seam-editing work into an editor. The choice depends on the files you already have, not on a special YouTube preference.
If you are comparing ways to run a prerecorded broadcast rather than choosing only an encoder, the guide to OBS and StreamYard for prerecorded YouTube video sets out a different workflow. This page stays with FFmpeg and a local file as the source.
Choose a visual input
Use a still-image video or a looping video as the visual input. This tutorial includes video deliberately: the official encoder materials cited here do not establish that an audio-only RTMP feed will be accepted as a YouTube Live broadcast. If you have separately verified an audio-only workflow for your channel, follow the current platform guidance; otherwise, send a visual track with the audio.
The example uses a file named still-image.mp4. It could be a simple prepared video showing a static image, or a visual loop that suits the channel. Check that it contains a video stream and plays for enough time to test the setup. The command repeats that input as well as the audio input, so a finite visual file can be used as the repeating source.
A still image avoids motion and can make a quiet listening stream less distracting, but you should make sure it is actually encoded as video rather than supplying an image format FFmpeg cannot use in this pattern. A video loop gives movement but adds another seam to inspect. If the image is important to the listener, make text legible at the size it will appear on a phone and avoid promising that a visual element stays fixed unless you have checked the rendered output.
For a broader checklist on preparing a stream before sending it, see video streaming tips for creators and businesses. The practical point here is to verify the visual input itself rather than discovering a missing or black picture only after the encoder is running.
Configure YouTube Live encoder details
In YouTube Studio, create or open the live stream in Live Control Room and locate the encoder settings for that stream. You need the stream URL or ingest destination and the stream key. YouTube’s guide to creating a live stream with an encoder describes the sequence: configure the encoder, start sending the feed, then check the preview and stream health. For a scheduled event, you may need to start the broadcast in Live Control Room after the preview appears.
Use the RTMPS destination supplied for your stream rather than copying an address from an unrelated example. YouTube recommends RTMPS for encoder streaming. Its guidance on live encoder settings and bitrates includes H.264 video and AAC or MP3 audio, a recommended two-second keyframe interval and a maximum of four seconds for RTMP/RTMPS. Those are platform recommendations, not proof that any particular file, connection or FFmpeg build will work unchanged.
The sample command uses 30 frames per second and -g 60, which makes a 60-frame GOP: two seconds at that frame rate. It also uses AAC audio at 44.1 kHz and 128 kbps, settings in YouTube’s guidance for stereo audio. Confirm the current recommendations and the resolution and bitrate appropriate to your stream in the official page before publishing; settings can change. The sample does not specify a video bitrate, so you may need to add one appropriate to your selected resolution and available upload capacity.
Keep the stream key private. It is not a channel name or a harmless label; it is part of the encoder destination information that lets YouTube accept the feed. Do not paste it into a public web page, shared screenshot or repository. If someone else can see it, reset it in Live Control Room and update the encoder configuration. For more on key and destination errors, see common FFmpeg stream-key configuration mistakes.
Build the FFmpeg loop command
This is an illustrative command pattern for a separate audio file and visual file:
ffmpeg -re -stream_loop -1 -i bowl-audio.mp3 -stream_loop -1 -i still-image.mp4 \\
-map 1:v:0 -map 0:a:0 \\
-c:v libx264 -pix_fmt yuv420p -r 30 -g 60 \\
-c:a aac -b:a 128k -ar 44100 \\
-f flv "rtmps://YOUR_YOUTUBE_INGEST_URL/YOUR_STREAM_KEY"
Replace both input paths and the destination with your actual files and the values supplied in YouTube Live Control Room. The example’s output container is FLV, commonly used for RTMP-family output. The URL shown is a placeholder, not a destination you can use as written. Avoid putting a real stream key into a command saved in a shared script, terminal history or screenshot.
The order of the options matters. -stream_loop -1 is an input option, so it appears before the -i for the file it should repeat. The first input is audio and the second is visual; -map 1:v:0 selects video from the second input and -map 0:a:0 selects audio from the first. Explicit mapping helps avoid accidentally sending the wrong stream when an input contains more than one track. FFmpeg’s command-line documentation describes the input/output option model and its formats documentation covers muxing options.
-c:v libx264 and -c:a aac encode the selected streams into formats supported by YouTube’s encoder guidance. -pix_fmt yuv420p and the frame-rate/GOP settings are common compatibility choices for this pattern, but still need to be checked against your build and the platform’s current requirements. -ar 44100 sets the audio sample rate; -b:a 128k sets the audio bitrate. If the file uses a different sample rate, FFmpeg will resample it for output. Listen to that encoded output during testing rather than assuming a setting alone guarantees the sound you want.
If you already have a video file with the bowl recording included, the separate mapping pattern is not necessarily suitable. Inspect its streams first, then map the video and audio from that same input as appropriate. Do not blindly copy the two-input command and expect it to choose the desired tracks.
For sustained operation, a process running on your own computer means that computer and its connection need to remain available. A cloud-based workflow can remove the need to leave your machine on: StreamNeo takes an uploaded video and sends it as a YouTube live stream, with the computer switched off. That addresses the specific burden of keeping a local machine running, but it does not clear rights to the recording or remove the need to check the broadcast and archive requirements.
Understand looping and real-time pacing
-stream_loop -1 asks FFmpeg to repeat the associated input indefinitely. It does not mean “make the whole output stream immortal”: the process can still stop, the connection can fail, an input can be unreadable, or the platform can end or reject a feed. The option repeats the file at the input level; you still need to run the FFmpeg process and send valid encoded output to the destination.
The -re option reads file input at real-time pace. Without real-time pacing, a file-based process can try to consume its input as quickly as the machine can process it, which is not the intended pace when feeding a live endpoint. The example places -re before the inputs so the file sources are read in real time. If you adapt the command for a live capture device or a different source type, check FFmpeg’s documentation and the source-specific behaviour rather than applying the flag automatically.
Each repeated input has its own duration and boundary. When the audio file ends, FFmpeg starts that input again; when the visual input ends, it repeats that too. If the files have different durations, the audio and image/video may reach their loop boundaries at different times. That is not necessarily a problem, but it is a reason to test the actual combination. A single combined video avoids separate input durations but still has its own audio and video edit points.
Looping also does not create an editorial transition. If the last bowl resonance decays into digital silence and the first moment begins with a sharp strike, the change may be audible every time the input repeats. You can leave the recording as-is if the boundary is acceptable; if it is not, edit or crossfade the source file and export a tested version before streaming. There is no command-line flag in this example that promises a seamless join.
Test the sound and the join
Do a private or otherwise controlled test before a public run, using the same files, codecs and destination arrangement you intend to use. Watch the YouTube preview and inspect stream health. Check that the picture is present, the audio is audible, the intended channel is receiving the feed, and the output does not unexpectedly stop when either input reaches its end.
Listen through at least one full pass and across the join. Pay attention to a click, a gap, a sudden change in loudness, a truncated bowl decay or a longer silence than intended. If you adjusted the file, test the exported version; changes to sample rate, encoding or edits can alter how the boundary sounds. A visual waveform can help identify abrupt changes but does not replace listening on ordinary headphones or speakers.
Check the audio level at a comfortable playback volume. A recording that sounds quiet when auditioned at one setting may be too loud after normalisation or encoding elsewhere in your chain. This example does not include a loudness filter because the right processing depends on the recording and desired presentation. Keep an unprocessed copy so you can compare and return to the original if a change makes the sound worse.
If you see a black screen or no audio, diagnose the mapped inputs and selected streams before changing several settings at once. Confirm that the files play locally, that the FFmpeg build supports the named encoder, and that the stream key and ingest destination belong to the intended live setup. The black-screen troubleshooting guide may help if the encoder is sending a feed but the video is not showing as expected.
A successful preview is useful evidence about the test, not a promise that every later broadcast will remain connected. Keep an eye on stream health at the start of a run and after you change files, settings, network or encoder version. For a 24/7 workflow, consider what you will do if the process stops overnight, and whether you can detect and restart it without exposing the stream key.
Check archive behaviour for long streams
A live broadcast and its YouTube archive are separate concerns. YouTube says streams shorter than 12 hours are automatically archived; a stream that exceeds 12 hours may not be captured at all. Review its current archive live streams guidance before deciding how long one continuous session should run. If retaining the full programme matters, plan a local recording as well rather than relying only on a platform archive.
A local copy is useful for more than archive insurance: it gives you a way to review what viewers heard and saw, and to retain a source for later editing if your rights permit that use. Make sure the recording location has room for the material and that you can retrieve the file after the stream. A removable drive is optional; FFmpeg does not require an external SSD or hard drive merely to send a stream. It can be a practical destination when you need to keep a local copy separate from the computer’s internal storage.
For retention, compare two approaches. A shorter live session reduces reliance on capturing a very long continuous broadcast; a longer session may better fit an always-on channel, but makes a separate recording plan more important. Neither choice guarantees that an archive will be available. Pick based on whether the priority is continuous public playback or preserving the entire programme, then test your local recording path before you need it.
If you split a broadcast into shorter sessions, plan the transitions and check how each scheduled stream is started and ended in Live Control Room. A transition between sessions can be more visible to viewers than an internal audio loop. Keep notes of the stream’s start time, file version and any interruptions so you can find issues in the local copy and distinguish them from an audio seam in the source.

FAQ
Does -stream_loop -1 loop the audio forever?
It tells FFmpeg to repeat that input indefinitely while the process continues to run. It does not prevent a process exit, connection interruption or platform-side issue, and it does not mean the loop boundary will sound smooth. Test the source and the broadcast rather than treating the flag as an uptime guarantee.
Can I send only the bowl audio, without a picture?
The official encoder guidance referenced here does not establish that an audio-only RTMP feed will be accepted as a YouTube Live broadcast. The command therefore includes a visual input; verify any audio-only setup separately against current YouTube guidance before relying on it.
Will YouTube save a 24-hour stream?
Do not count on it. YouTube says streams shorter than 12 hours are automatically archived and streams exceeding 12 hours may not be captured. Keep a local recording if you need to preserve the full programme.
Does traditional or devotional subject matter make the recording free to use?
No. Rights depend on the actual recording and its licence, not merely on the instrument or subject. Use your own recording or confirm that the permission covers live broadcasting and any archive, and keep evidence of that permission.
