Yes. You can send a video file to YouTube Live from an encoder such as OBS Studio and set its media source to loop, so the file starts again when playback ends. The repeated playback happens before the feed reaches YouTube.
That is different from the Loop command in YouTube’s viewer player, which repeats an uploaded video for the individual viewer and does not create a live broadcast. A loop setting also cannot guarantee that a computer, internet connection or live stream will run without interruption all day.
Encoder looping and viewer Loop do different jobs
When you stream a prerecorded file through OBS, OBS plays the file and sends its output to YouTube as a live feed. Turning on Loop for the source tells the encoder to start that file again at the end. Viewers receive the resulting live broadcast; they do not each need to turn on a playback setting.
YouTube’s player Loop command applies to a viewer’s playback session for a video. It does not send your local file into Live Control Room, create an encoder feed or make a prerecorded video appear as a live broadcast. If you want to loop a video on YouTube Live, configure repetition in the encoder.
| Approach | Where repetition happens | What the viewer gets |
|---|---|---|
| OBS Media Source with Loop enabled | In OBS, before the feed reaches YouTube | A live broadcast in which the source video repeats |
| YouTube player’s Loop command | In an individual viewer’s player session | Repeated playback of that video for that viewer, not a live broadcast |
This difference helps when you are testing. If your own browser repeatedly plays an ordinary video, that proves only that viewer playback is looping. To verify a live loop, check the encoder preview and the live broadcast itself. For a walkthrough focused on the source setting, see how to loop videos in a 24/7 YouTube livestream.
Create or select a YouTube Live stream
In YouTube Studio, open Live Control Room and create a live stream or select one you have already set up. YouTube’s instructions for creating a live stream with an encoder describe how to connect an encoder using the stream URL and key. Follow the current screen labels and prompts, since the interface can change.
Before you begin, decide whether you are creating a one-off broadcast or reusing a stream configuration. Give the event a recognisable title and check the audience and visibility settings you intend to use. A scheduled event can give viewers a page to find in advance, while the encoder still has to send the actual feed and the broadcast may require you to start it from Live Control Room.
Prepare the file first. Confirm that it plays from beginning to end on the computer you will use, and that its audio is suitable for the full duration. If it is a devotional music video, ambience track or study session, check that you have permission to use every image and sound in a live broadcast. YouTube can scan live content for third-party matches; its guidance on copyright issues with live streams explains that matching content can lead to interruptions or replacement of the feed. Permission for an individual work may not be the same as an allowlisting arrangement for your channel.
Add the video as an encoder source
In OBS, create a scene for the broadcast and add the local video file as a Media Source. Select the file from your computer, then check that it appears in the scene preview and that its sound reaches the audio meter when it plays. A scene is the arrangement OBS sends out; if the file is missing from that scene, the correct file on disk will not help the broadcast.
OBS’s Media Sources documentation describes the source controls, including Loop. For a single file, Media Source is the direct choice. If you need to repeat a playlist rather than one file, OBS also documents a VLC Video source; that source depends on VLC being installed. A playlist changes the job: check each item and the transitions rather than assuming that a single-file setup will behave the same way.
Keep the scene simple at first. Add titles, logos or overlays only after you have confirmed the file and audio work. This makes it easier to identify the cause if the preview is black, silent or showing the wrong item. If the machine is already close to its limits, extra scenes and processing can make it harder to keep a stable feed. YouTube’s encoder settings guidance recommends testing settings and choosing quality that is reliable on the connection available to you; it does not establish one universal computer specification for every setup.
Enable Loop on the source
Open the Media Source’s properties and enable its Loop option. Once playback reaches the end, OBS should begin the file again. The setting belongs to that source, so check it in the scene you will actually stream; adding a second source or switching scenes can mean you are no longer sending the source you tested.
Let the file play through an end and a restart while watching the preview. Check whether the picture returns to the opening cleanly and whether the sound has a gap, click or abrupt change. Looping repeats the file; it does not edit the file to create a seamless join. If a bhajan recording ends with several seconds of silence, that pause will recur every time it loops. If a lofi video has a visible fade to black, viewers will see that fade at each boundary.
If the repeat point is distracting, revise the file itself or choose a better start and end point, then test the updated source. For audio episodes or segments where silence between items is the issue, the advice on removing gaps when looping podcast episodes on YouTube covers a related editing problem. It is not a substitute for testing the exact file and encoder scene you plan to use.
Connect the encoder with the stream URL and key
YouTube provides a stream URL and a stream key for the selected live stream. In OBS, open the streaming settings, choose YouTube or the relevant custom configuration shown in your version, and enter the details. The URL tells OBS where to send the feed; the key associates that feed with your YouTube stream. Treat the key as a credential: do not include it in a screenshot, public post or message to someone who does not need it.
Check that the stream details in OBS correspond to the live event you selected. If the feed reaches a different event, or YouTube reports that it is not receiving a signal, stop and verify the URL and key rather than repeatedly changing unrelated video settings. The steps in fixing YouTube stream key errors on a 24/7 Indian music channel are useful when connection details are the specific problem.
When ready, start streaming from OBS. Watch Live Control Room until YouTube detects the incoming feed and the preview is available. Depending on the workflow, you may need to click Go live in YouTube as well; sending an encoder feed and publishing the broadcast are distinct steps. YouTube’s encoder guide gives the current connection workflow, so use it if labels or controls differ from the instructions you remember.
Preview and monitor the broadcast
Do not treat a successful connection as proof that the all-day setup is sound. Check the Live Control Room preview for the expected picture and sound, then view the broadcast as a viewer if practical. Confirm that the file is playing, that the loop boundary behaves as intended and that the stream is reaching the right audience and visibility setting.
During the broadcast, keep the encoder computer awake, the encoder open and the network connection available. A laptop that sleeps, a router that restarts or an internet outage can interrupt the feed even when Loop is correctly enabled. YouTube recommends testing the encoder and monitoring stream health and audio and video quality. If you cannot watch continuously, arrange checks that suit the importance of the channel and make sure you know how to respond if the signal drops. Neither OBS nor YouTube promises that an individual device, connection or stream will remain uninterrupted all day.
For a channel that needs to keep running while your own computer is switched off, StreamNeo can take away the need to leave the encoder open on that computer: upload the file once, connect your YouTube stream key, and the broadcast runs with monitoring and automatic restart if it drops. It is YouTube-only, and it does not change YouTube’s rules, rights requirements or archive limits.
A working live feed is not the same thing as a dependable recording of that feed. YouTube says streams shorter than 12 hours can be automatically archived and warns that a stream exceeding 12 hours may not be captured at all. That warning concerns the archive, not a rule that the live feed must stop at that point. YouTube recommends keeping a local archive as a backup; see its current archive live streams guidance.
Live DVR is another separate feature. YouTube says DVR capabilities may be limited or unavailable for streams longer than 12 hours, which affects whether viewers can rewind during the broadcast. If viewers need to catch an earlier section, do not assume that a live stream running continuously will provide every DVR control. The current DVR guidance explains the distinction.
If the stream drops, first check whether OBS is still sending, whether the computer and connection are available, and what Live Control Room reports. After a restart, confirm that the feed is back and the file is in the expected position. You can also check whether a YouTube live stream is actually looping to distinguish a repeat in the encoder from ordinary playback behaviour. When finishing, stop the broadcast through the intended YouTube workflow and stop sending content from the encoder, as YouTube’s encoder instructions advise.
What all day does and does not promise
The file can repeat for as long as the encoder keeps playing and sending it, but “all day” describes an intention, not a guarantee of uninterrupted operation. The loop controls the source’s repeat behaviour; it does not prevent power loss, a software fault, a network break or a platform action. Test the actual computer, connection and event workflow before relying on the channel for a long session.
Plan separately for the live feed, the archive and viewer rewind. The live broadcast may continue beyond the archive and DVR thresholds described above, but the resulting replay or rewind controls can be limited. If preserving a complete recording matters, make a local recording or use another suitable backup plan, and verify that it is being saved rather than assuming YouTube’s archive will cover every long stream.
Choose a stream quality your available connection can sustain rather than aiming for the highest setting by default. A stable, tested picture and sound are more useful than a setting that produces recurring dropped frames or buffering. Test at the intended resolution and bitrate, then observe stream health under realistic conditions. There is no single computer model or internet plan that can be recommended from the platform guidance for every channel.
Finally, review rights before you press Go live. A file that plays locally without error can still match third-party material once broadcast. Keep records of the permissions you rely on and check YouTube’s current copyright guidance if a match or interruption occurs. A loop setting is a playback instruction, not permission to rebroadcast the contents.

FAQ
Can I loop a video on YouTube Live without OBS?
You need an encoder or another workflow that sends the prerecorded file into the live broadcast and repeats it. OBS is one documented way to do that; YouTube’s viewer Loop command alone does not create the broadcast. Choose a workflow you can test and monitor before relying on it.
Does a loop setting mean the stream will stay live all day?
No. It tells the encoder to play the source again when it reaches the end, but it cannot prevent a computer, connection or stream interruption. Test the setup and monitor the feed, with a plan for what you will do if it drops.
Will YouTube save the full stream as a replay?
Not necessarily. YouTube says streams shorter than 12 hours can be automatically archived and warns that streams exceeding 12 hours may not be captured. Archive availability is separate from whether the live feed was running, so keep a local recording if a complete copy matters.
Can viewers rewind a long live stream?
They may not have full DVR controls: YouTube says DVR capabilities may be limited or unavailable for streams longer than 12 hours. Check the current YouTube guidance for the stream you plan to run, and do not confuse rewind with looping the source file.
