You can make a YouTube live stream repeat a prerecorded video by looping the file in an encoder such as OBS Studio. Add the video as an OBS Media Source, enable its Loop setting, then send the resulting feed to YouTube with the stream URL and stream key.
This is different from pressing Loop in the YouTube player. The player setting repeats playback for one viewer; it does not send your file back to YouTube as a live broadcast. For an always-on channel, the repeat must happen in the encoder or in the service sending the live feed.
Check that your channel can go live
Before configuring OBS, check whether your YouTube channel is ready for live streaming. YouTube says the channel must be verified and must not have had live-streaming restrictions in the past 90 days. If this is your first time enabling live streaming, activation may take up to 24 hours, so do not leave this step until the hour before your planned broadcast.
You can review the current requirements in YouTube's live-streaming eligibility guidance. The exact screens can change, but the practical order remains the same: verify the channel, enable live streaming, and wait for activation if YouTube requires it.
If live streaming is not active yet, use the channel's YouTube Studio controls to begin the process. A new channel may be able to prepare its video and OBS scene while activation is pending, but it will not be able to complete the live connection until YouTube permits the broadcast.
It is also worth checking whether the channel has an existing restriction or warning that could affect live access. Do not treat a successful OBS setup as evidence that the channel is eligible. Encoder settings and channel eligibility are separate parts of the process.
If you are setting this up for a devotional channel, a local news loop or a study station, make sure the channel itself is the one you intend to use. The stream key belongs to that channel. Sending a key from another channel can result in the feed appearing in the wrong Live Control Room, which is confusing when you are trying to diagnose a blank preview.
For a more detailed first-time walkthrough, see how to enable live streaming on YouTube for the first time. It is particularly useful if the live controls are missing or YouTube has not yet finished activating the channel.
Create or schedule the stream in YouTube Studio
Once live streaming is available, open YouTube Studio and go to the live-streaming area. Choose the option for an encoder stream. You can start one for now or schedule it for later, depending on whether you want to test immediately or prepare a public event in advance.
In the Live Control Room, YouTube provides the connection details that OBS needs. These are normally the stream URL and the stream key. The URL tells OBS where to send the feed. The key identifies which YouTube stream should receive it.
Treat the stream key like a password. YouTube describes it as sensitive connection information, and its guidance explains that a channel owner or manager can reset it if it is compromised. Do not paste it into a public tutorial, send it in a group chat unnecessarily or store it in a screenshot that you share with someone else.
You can usually reuse a stream key within the workflow YouTube provides, but check the current Studio screen rather than assuming that an old key belongs to the new broadcast. If you reset the key, update OBS before starting the feed. An old key can make a perfectly configured encoder appear not to connect.
Scheduling gives you a chance to add the title, description, thumbnail and visibility settings before the broadcast. For an always-on channel, write a title that accurately describes what viewers will receive. The live stream title guide can help you make the title clear without implying that a prerecorded loop is a different type of programme.
Do not click the final go-live control yet. First, configure the video in OBS and connect the encoder. YouTube needs to receive a feed before it can show you the meaningful preview and stream-health information.
Add the video as an OBS Media Source
Install and open OBS Studio on the computer that will send the stream. Create a new scene, or select a scene you already use for the channel. A scene is the collection of picture and audio sources that OBS sends to YouTube.
In the Sources box, add a Media Source. Give it a useful name such as Main loop rather than leaving several sources with identical names. In the Media Source properties, choose the local video file you want to broadcast.
OBS's official Media Sources documentation describes the file source and its playback controls. The file needs to be available to the computer while OBS is running. If you move, rename or disconnect it after configuring the source, OBS may no longer be able to read it.
Check the canvas after adding the file. A video with a different shape from your intended YouTube layout may show empty space, cropping or an unexpectedly small picture. Right-click the source and use the transform options to fit it to the canvas where appropriate. Look at the complete frame, not only the centre of the image. Text near an edge can disappear when the source is cropped.
Your file's audio should appear in the OBS audio mixer when the video plays. If the meter does not move, the file may have no usable audio track, the source may be muted, or the audio monitoring and output settings may need attention. A silent devotional recording, music station or news loop can look correct in the preview while still giving viewers no sound.
Do not add multiple copies of the same file unless you have a specific reason. One Media Source with Loop enabled is easier to inspect. If you want several different videos in sequence, that is a playlist problem rather than a single-file loop. In that case, follow the guide to adding multiple videos to an OBS 24/7 stream playlist, then test the transitions and audio between files.
Before continuing, play enough of the file to confirm that the intended opening frame, picture orientation and audio are present. You do not need to wait for the whole video during setup, but you do need to know that OBS can open it and that the source is visible in the scene.
Turn on the Media Source Loop option
Select the Media Source in OBS and open its properties. Turn on the option labelled Loop, then save the setting. OBS uses this property to play the file again when playback has completed.
This is the setting that makes one local video repeat in the encoder. It is not a YouTube player control and it is not the same as restarting a browser tab. When the file reaches its end, OBS starts the source again and continues including it in the outgoing feed.
Watch one complete ending and restart if the file is short enough to test. Check for a black frame, a pause, a sudden audio change or a visible jump. Some files have a natural end that is easy to accept, while others stop abruptly. The loop function repeats the file; it does not edit the join or create a crossfade.
If the source does not restart, reopen its properties and confirm that Loop is still selected. Also check that the source is not hidden, that the scene remains active and that the file path still works. A media source can be configured correctly but fail later if the underlying file is moved or the computer enters a power-saving state.
For a 24/7 channel, place the file in a stable local folder and avoid changing its name after the scene is ready. Keep a copy of the original elsewhere. If the file becomes damaged, the loop setting cannot repair it, and a backup gives you something to restore without rebuilding the whole scene.
Connect OBS to YouTube with the URL and key
Open OBS Settings and go to the Stream section. Choose the YouTube service if it is available in your OBS installation, or use the custom server option when YouTube gives you a server URL and stream key to enter manually.
Copy the stream URL from YouTube Studio into the server field in OBS. Copy the stream key into the key field. Take care not to include an extra space at the beginning or end. If you have reset the key since opening OBS, copy the current one again.
YouTube recommends RTMPS for secure ingestion. Its encoder streaming guidance covers the connection process and current recommendations. Use the settings supported by your encoder, computer and connection rather than copying a bitrate from an unrelated channel. A setting that works for one file and connection may not suit another.
Save the settings, but do not start the public broadcast simply because OBS has accepted the text. Start the stream from OBS so that it begins sending the feed, then return to YouTube Studio. YouTube should begin processing the incoming signal and show a preview when it has enough information to do so.
If there is no preview, check the connection in this order:
- Confirm that live streaming is active on the correct channel.
- Confirm that the URL and stream key belong to the current Live Control Room event.
- Check that OBS is using the intended scene and that the Media Source is visible.
- Check whether OBS reports dropped frames, a failed connection or an encoder error.
- Check the computer's internet connection and whether another application is using significant upload capacity.
Do not publish a blank or silent feed while troubleshooting. If YouTube shows a preview but the image is wrong, fix the OBS scene before making the stream public. If the preview is correct but the stream health warning remains, wait for the diagnosis in Live Control Room and inspect the feed before changing several settings at once.
Preview the picture and check the audio
The preview is where you confirm that the feed leaving OBS is the feed viewers will receive. Look for the full frame, readable text, correct orientation and the expected opening or repeated section. Then listen to the audio on a separate device if possible, because monitoring only through the computer running OBS can hide problems in the viewer experience.
Watch the audio meter in OBS while the file plays. It should respond to the recording rather than remaining permanently flat. Listen for clipping, a very quiet track, an unexpected second audio source or a delay between speech and picture. Do not assume that a moving meter means the mix is comfortable to hear; it only shows that audio is present.
YouTube recommends testing before a live broadcast and monitoring stream health during it. Its stream health guidance is the appropriate reference when Studio reports an ingestion or quality problem. Test with the same type of movement and audio that the real loop will contain. A static image does not reveal the same problems as scrolling news text or a music video.
If your content includes speech, announcements or aarti vocals, listen at the beginning and near the end of the file. Some files have audio that starts late or ends before the picture. Because the file repeats, a defect at the ending can occur on every cycle and become more noticeable to regular viewers.
YouTube says a live stream under 12 hours can be automatically archived, while a stream longer than 12 hours may not be captured at all. That matters for a channel intended to run through the day and night. Do not promise yourself a complete YouTube recording of a 24/7 broadcast. If you need an archive, consider a separate local recording plan and check YouTube's current live-stream archive information.
A local archive also gives you a way to inspect what was actually sent if viewers report a fault. Keep enough storage for the recording you intend to retain, and make sure the computer does not sleep or restart during the planned broadcast. These are operating considerations rather than features provided by the Loop checkbox.
If leaving a computer running is the specific problem, StreamNeo removes that part of the routine by letting you upload the video, add your YouTube stream key and have the channel run from the cloud, with monitoring and automatic restarting if the feed drops. It is still your responsibility to check the file, channel access, rights and YouTube settings before broadcasting.
Encoder looping is not YouTube player replay
There are two different meanings of “loop” in this workflow. The first is encoder looping: OBS reads a local file, reaches the end, starts it again and sends that repeated output to YouTube as one continuous live feed. This is what you need when viewers should see a live channel that continues beyond the length of the original file.
The second is player replay: a viewer chooses a playback loop in the YouTube player, or a video is played again in a browser. That repeats the video for that individual viewer after or during playback. It does not send the file back through your encoder, does not create a live broadcast and does not keep the channel live for other viewers.
The distinction is important for a bhajan recording, an ambient study video or a local information loop. If the file is 40 minutes long and the channel should continue for many hours, the encoder must repeat it before YouTube receives the feed. Asking viewers to enable player replay does not solve the broadcaster's problem.
You can compare the two workflows like this:
| Feature | OBS Media Source Loop | YouTube player replay |
|---|---|---|
| Where it happens | In the encoder before the feed reaches YouTube | In an individual viewer's player |
| What it repeats | The file being sent as part of the live feed | Playback for that viewer |
| Does it create or maintain a live feed | Yes, when the encoder remains connected | No |
| Who sees the result | Viewers receiving the live broadcast | Only the viewer using the playback control |
| Suitable for an always-on channel | Yes, subject to the encoder and connection continuing to work | No |
The encoder approach still has practical limits. A computer can lose power, OBS can stop, the internet connection can fail and a file can become unavailable. YouTube can also show stream-health warnings or apply channel restrictions. Looping a file is one configuration step, not a guarantee that a broadcast will run without interruption.
Think about the content as well as the connection. Repeating a file does not change ownership or licensing questions, and it does not make a channel eligible for monetisation. You can read what applies to monetising a 24/7 looped stream before building a schedule around it. For worship music in particular, review permission requirements rather than assuming that a live loop is treated differently from an ordinary upload.
If the stream later becomes unavailable, use the troubleshooting steps in why a 24/7 stream gets “Video unavailable”. Keep the diagnosis separate from the loop setting: a correctly looping file cannot overcome a disabled live channel, an invalid key or a broken connection.

FAQ
Can I loop a normal YouTube video into a live stream?
Not with the YouTube player loop control. You need an encoder or another broadcasting workflow that reads the file and sends it to YouTube as a live feed, with the repeat function enabled in that workflow.
Does YouTube activate live streaming immediately?
Not always. YouTube says first-time live-stream activation may take up to 24 hours, so enable it in advance and confirm that the Live Control Room is available before planning the broadcast.
Will YouTube archive a 24/7 loop?
YouTube says streams longer than 12 hours may not be archived, so do not rely on the channel page as a complete recording of an always-on broadcast. Use a separate recording or archive plan if retaining the full output matters.
What should I do if the preview is blank?
Check that the channel is eligible, OBS is sending the feed, and the current YouTube stream URL and key are entered correctly. Then confirm that the intended scene is active, the Media Source is visible and the file still exists at the path OBS is using.
