A looping yoga nidra video can run as a YouTube Live broadcast when FFmpeg reads the file repeatedly and sends a continuous encoder feed to a YouTube live event. YouTube does not loop the video for you: the loop happens before the feed reaches YouTube.
You need an eligible, verified YouTube channel, a live event created in YouTube Studio, the event's stream URL and private stream key, and a computer or hosted environment that can keep FFmpeg running. The workflow below uses H.264 video, AAC audio, RTMPS and a two-second keyframe interval as a practical starting point.
Create the YouTube Live event
Start in YouTube Studio rather than in FFmpeg. Open the Live Control Room and create or schedule a live stream using the encoder workflow. Choose the title, description, visibility and other event details before you start sending video.
Your channel must have live streaming enabled. YouTube's current encoder guidance says the channel must be verified and must not have live-streaming restrictions in the previous 90 days. If live streaming is unavailable, resolve that before troubleshooting FFmpeg. The problem may be channel eligibility rather than your command. This guide to YouTube saying live streaming is unavailable covers that distinction.
For the first run, use an unlisted event or another test arrangement that keeps the broadcast away from your audience. This lets you check the video, audio, connection and repeat behaviour without announcing an unfinished stream. When the test is acceptable, create or edit the public event you intend to share.
Inside the Live Control Room, select the encoder details and note the ingestion URL and stream key. YouTube may show these as separate fields. FFmpeg can accept a complete RTMPS destination, so the URL and key may be joined in the command, but do not assume that every interface presents them in exactly the same way. Follow the fields YouTube displays for your event.
YouTube's instructions for creating a live stream with an encoder explain where these values appear and how the event moves from setup to preview. Keep the Studio page open while testing so you can see whether YouTube is receiving the feed.
Protect the stream key
Treat the stream key as a password for the live feed. Anyone who obtains it may be able to send a different broadcast to that event, so do not put it in a public tutorial, screenshot, shared document, shell history that other users can read, or source-control repository.
The command later in this article uses placeholders rather than a real key. Replace them only on the machine where FFmpeg will run. If you need to ask someone for help, redact the key and leave enough of the surrounding command to show the protocol and options without revealing the secret.
Use separate keys or reset the key when you have a reason to believe it has been copied. YouTube's encoder setup guidance describes how a channel owner or manager can manage or reset a compromised key. After a reset, update the FFmpeg destination before starting the encoder again. A previously working command will not work with an invalidated key.
Also check the destination before pressing Enter. A typo in the ingestion URL and an invalid key can look similar in the Live Control Room because neither produces a healthy incoming feed. Do not paste the complete command into a public issue, chat or article, even if the event is unlisted.
Prepare the video and audio inputs
Begin with the source file, not with the output command. Play the yoga nidra video from start to finish, including its opening and closing seconds. Confirm that the spoken guidance is audible, the background sound is intentional, the picture has no unwanted black frames, and the file ends where you expect the loop to begin again.
Check that you have the right to broadcast both the video and audio. A yoga nidra recording may contain narration, music, nature sounds, artwork or stock footage licensed for a limited use. A permission to download or watch a file does not automatically give permission to rebroadcast it as a continuous live stream. Keep your licence or permission records with the source project.
The command below assumes a file named yoga-nidra.mp4. Put the file in the working directory or use its full path. If the filename contains spaces, quote the path. On Windows, the quoting and path format depend on the shell you use; the FFmpeg options remain the same.
A consistent source makes looping easier to diagnose. If the file has unusual timestamps, several audio tracks, variable frame rate or a damaged stream, inspect and convert a working copy before building the live command. Do not overwrite the original. The goal is to know whether a fault belongs to the source file, the loop operation or the YouTube connection.
For a yoga nidra channel, audio deserves particular attention. Long spoken passages make missing audio more noticeable than in a visual ambience stream. Listen at the intended playback level and check for sudden silence at the loop boundary. FFmpeg can repeat the input, but it cannot decide whether a jarring transition is acceptable for your audience.
Loop the input with FFmpeg
In FFmpeg, -stream_loop -1 tells the input to repeat indefinitely. It is an input option, so place it before the input's -i option. The -1 value means infinite repetition. The -re option makes FFmpeg read the file at its normal playback rate rather than sending it as quickly as the computer can process it.
Here is a starting command for a 30 fps H.264/AAC stream using a 720p30 bitrate recommended by YouTube's encoder settings guidance:
ffmpeg -re -stream_loop -1 -i yoga-nidra.mp4 \
-c:v libx264 -preset veryfast -tune zerolatency \
-pix_fmt yuv420p -r 30 -b:v 6M -maxrate 6M -bufsize 12M \
-g 60 -keyint_min 60 -sc_threshold 0 \
-c:a aac -b:a 128k -ar 44100 \
-f flv 'rtmps://INGESTION_URL/STREAM_KEY'
Replace yoga-nidra.mp4 with the source path and replace the destination placeholders with the values supplied by YouTube. Do not copy the placeholder syntax literally. Do not include brackets or explanatory text in the actual destination.
The video settings have specific jobs. libx264 encodes the picture as H.264. veryfast is a practical CPU trade-off, while zerolatency avoids adding unnecessary encoder buffering for a live feed. yuv420p is a widely compatible pixel format. -r 30 produces 30 frames per second, and -g 60 with -keyint_min 60 targets a keyframe every 60 frames, which is two seconds at 30 fps. -sc_threshold 0 avoids changing the interval because of scene changes.
The example's -b:v 6M is YouTube's published H.264 recommendation for 720p30, not a universal requirement or a guarantee that your connection can sustain it. If your source and chosen output are 1080p30, YouTube's current guidance lists 10 Mbps for H.264. Check the current YouTube encoder settings, bitrates and resolutions before selecting a different resolution or codec.
-maxrate and -bufsize help keep the encoded output near the selected target rather than allowing large bitrate swings. The upload connection must still sustain the resulting stream, along with normal network overhead. If the connection is unreliable at the selected bitrate, lower the output resolution or bitrate and test again instead of assuming the source's original quality must be preserved.
The audio options encode AAC at 128 Kbps and 44.1 kHz. YouTube's guidance lists AAC and MP3 as supported audio choices and recommends 128 Kbps for stereo AAC. If your source contains multiple audio tracks, this simple command may select the default track. Inspect the file when the chosen narration or music does not appear in the output.
The FFmpeg documentation explains the command-line option conventions and input option ordering. That documentation supports the use of -stream_loop -1; it does not mean that every source file will loop cleanly without inspection. A loop can expose timestamp or stream-specific problems, so use the test event before making the broadcast public.
Choose the output settings deliberately
Do not choose resolution merely because the source file has a larger frame size. YouTube recommends selecting a bitrate that matches the resolution, frame rate and codec while remaining reliable for the available upload connection. A stable lower-resolution feed is more useful than a high-resolution feed that repeatedly loses health.
| Output choice | Starting point in this workflow | What to check |
|---|---|---|
| 720p at 30 fps, H.264 | 6 Mbps video | Whether the upload remains stable at the selected bitrate |
| 1080p at 30 fps, H.264 | 10 Mbps video | Whether the connection and encoder can sustain the higher output |
| Stereo AAC audio | 128 Kbps | Whether the narration and background audio are present and balanced |
| Keyframe interval | 2 seconds | At 30 fps, use a 60-frame GOP and stay within YouTube's maximum interval guidance |
The figures in this table are YouTube's published recommendations for the relevant H.264 and AAC settings, not measurements from this article. YouTube also lists other codecs and frame rates. If you choose a different codec, resolution or frame rate, consult its current table rather than carrying these values across unchanged.
Re-encoding gives you control over the frame rate, codec, bitrate and keyframe interval. It also uses CPU. Stream copying can reduce processing work only when the existing codecs, timestamps and keyframe structure already suit live ingestion; it is not a safe shortcut for every MP4. For a first setup, the explicit H.264/AAC command is easier to reason about and troubleshoot.
If the computer struggles, watch the encoder's CPU use and output timing during the test. A faster preset may reduce CPU load, but the resulting quality and bitrate behaviour still need checking. Avoid changing several variables at once. Change the output resolution, preset or bitrate, then run another test so you know which change affected the result.
Send the encoder output to YouTube
The final output in the command is an FLV container sent over RTMPS. RTMPS is YouTube's encrypted transport recommendation for encoder streams. The destination combines the ingestion address and the event's stream key in the form accepted by FFmpeg.
YouTube's API documentation describes the live stream's ingestion address and stream name fields. It is useful when an application or encoder presents the server URL and stream name separately. For this manual command, use the exact URL and key shown for the event in YouTube Studio, and check whether the interface expects the key appended to the URL or entered separately.
Start the command from a terminal on the computer that holds the source file. Leave the terminal running. Normal FFmpeg output should show input details, encoded frames, elapsed time and a continuing output process. Those messages only describe what FFmpeg is attempting; the YouTube Live Control Room is the place to confirm that the platform is receiving a usable feed.
Do not close the terminal when the first repeat begins. -stream_loop -1 keeps reading the input, but it does not turn a stopped computer into an always-on service. Sleep settings, operating-system updates, power loss, network changes and terminal closure can all interrupt the feed. For an overnight or continuous channel, the machine running FFmpeg needs power, a stable connection and an operating plan for restarts.
If you need unattended recovery, separate it from the first successful test. First establish that the file, command and YouTube event work. Then consider a service manager, scheduled task or another restart method appropriate to your operating system. This FFmpeg troubleshooting guide for a stream that keeps stopping is useful once you have an actual failure to investigate.
For operators who do not want a personal computer left running, StreamNeo removes the repeated file-running and overnight restart work: upload the video, provide the YouTube stream key, and let the cloud broadcast continue while your computer is switched off. It remains a YouTube-only workflow, so you still create and manage the YouTube event and should test the resulting feed.
Preview and test the live feed
Start FFmpeg while the event is still unlisted or otherwise limited to your test audience. Open the Live Control Room preview and wait for YouTube to report the incoming feed. Check the picture for the correct crop, resolution, frame rate and visible artefacts. Listen through the beginning, a representative spoken section and the transition where the file repeats.
The test should resemble the real broadcast. If the public stream will run overnight, test with the same source, output settings, network connection and computer power settings. A short command launch proves only that FFmpeg started; it does not prove that the source repeats correctly or that the connection remains healthy.
Watch stream health messages rather than relying only on the local terminal. Buffering or poor health usually means that the upload cannot reliably carry the selected output, although incorrect event details or a failing source can produce related symptoms. Compare the observed upload capacity with the selected bitrate, lower the resolution or bitrate if necessary, and repeat the test.
If there is no preview, first check the event selected in Studio, the ingestion URL and the stream key. Confirm that the key has not been reset and that the destination has no accidental spaces or missing characters. If the key was ever shared, reset it before continuing rather than treating secrecy as optional.
If the picture repeats but the audio does not, inspect the source streams and the audio track selected by FFmpeg. If the repeat produces a timestamp warning or a visible jump, test a converted working copy and compare the loop boundary. Official guidance does not establish one command that resolves every source-specific timestamp problem, so avoid presenting a successful result from one file as a guarantee for another.
Once the preview and health indicators are acceptable, decide whether to make the event public or share its scheduled link. Keep the unlisted test available until you have recorded what worked: source filename, output settings, event details and the date of the test. This makes the next restart or content change easier to diagnose.
For longer-running channels, plan what happens after a stop. YouTube says streams under 12 hours are automatically archived under its current encoder setup guidance. Do not assume the same archive behaviour for a longer broadcast without checking the current official information. If the yoga nidra session is intended to repeat for many hours, decide whether separate events or a controlled stop are more suitable for your channel.
What to do before going public
Use this final sequence rather than changing settings while viewers are already watching:
- Play the source file and verify the narration, music, artwork and loop boundary.
- Confirm that the channel is eligible for live streaming and that the correct YouTube event is open.
- Keep the stream key private and use the current key for that event.
- Run FFmpeg with
-re -stream_loop -1and confirm that looping is an input operation. - Check the output resolution, bitrate, codec, audio and two-second keyframe target.
- Watch the Live Control Room preview and stream health during a test.
- Correct one problem at a time and test again.
- Only then change visibility or share the public event.
If you regularly publish devotional, meditation or sleep content, keep a small setup record for each source. Include the file name, expected duration, frame rate, audio track, command settings and any known transition issue. A record is more useful than relying on memory after a stream stops overnight.
The same principles apply when the content changes from yoga nidra to sleep sounds or ambience: YouTube still needs an event and an incoming encoder feed, while FFmpeg still needs to read the file at real time and repeat it. For a related overnight example, see how to keep a sleep sounds YouTube Live stream running overnight. If you are deciding whether a playlist can replace the encoder, YouTube playlists running a 24/7 bhajan live stream explains why the two arrangements are different.
Before committing, compare the operating options on the pricing page. When the file and channel are ready, start free — 24-hour trial, no card.
FAQ
Does YouTube Live loop a prerecorded video automatically?
No. YouTube receives a live encoder feed; it does not automatically replay your uploaded file as part of this workflow. FFmpeg's -stream_loop -1 repeats the input before the encoded output is sent to YouTube.
Where does -stream_loop -1 go in the FFmpeg command?
Place it before the input it controls, as in -stream_loop -1 -i yoga-nidra.mp4. It is an input option and the -1 value requests infinite repetition. If you place it after the input, the command may not apply the option as intended.
Can I publish the stream key in a tutorial or screenshot?
No. Treat it like a password for the live feed and replace it with a placeholder before sharing anything. If it has been exposed, reset it in YouTube Studio and update the FFmpeg destination.
What should I do if the stream buffers or has poor health?
Check the Live Control Room message and compare the selected bitrate with the upload connection's sustained capacity. Lower the resolution or bitrate, confirm the event and key, and run another unlisted test before making the stream public.
