“Loop a YouTube playlist” can mean repeating a playlist while watching it, or repeating local video files that are feeding a live broadcast. For a YouTube Live channel, the repeat setting belongs in the playback source or encoder, not in the viewer’s YouTube controls.
With OBS, use a Media Source for one local file and enable Loop. For an ordered collection of files, use a VLC Video source, add the files to its playlist, and enable Loop Playlist. The steps below also cover scene visibility, YouTube connection settings, and the test you should run before leaving the channel unattended.
Two different meanings of playlist looping
The first meaning is viewer-side playback. If you open a playlist on YouTube, you can use YouTube’s Loop control to repeat it while you watch. On desktop, open a video in the playlist, expand the playlist panel, and select Loop. YouTube also documents playlist repetition controls for Android, televisions, and gaming consoles in its playlist playback instructions.
That control changes what happens in that viewer’s YouTube player. It does not reach back into OBS, select files on your computer, or make an OBS source repeat. A viewer can loop a playlist while your live broadcast is showing a single continuous programme, but that does not alter the broadcast source.
The second meaning is production-side looping. Here, you have one or more local video files and want OBS to keep presenting them as the source of a YouTube Live broadcast. The files must be repeated before they are sent to YouTube. OBS controls the playback, while YouTube receives the resulting live video.
This distinction matters for a devotional channel with a recorded bhajan programme, a study channel using a long ambience file, or a local business running a prepared information loop. If the source stops after one file or one pass through a playlist, enabling Loop in a viewer’s YouTube window will not repair the broadcast. You need to configure the source that OBS is actually using.
There is a related distinction with embedded players. The YouTube IFrame Player API documents a loop parameter for playlist playback, and notes that repeating one embedded video requires the video ID to be supplied as a playlist as well. That applies to an embedded player, not to an OBS source. It is useful when building a web page, but it is not the setting for a local file in a live encoder. The API’s player parameter documentation describes that separate case.
Loop one local file with an OBS Media Source
Use an OBS Media Source when the broadcast needs to repeat one local video file. This is the simplest route for a single long programme, a visual background with music, a recorded prayer service, or one prepared loop containing all the material you want to show.
Start with the scene that will be used for the broadcast. In OBS, add a new source and choose Media Source. Give the source a clear name, such as Main programme or Morning loop, so that you can identify it later if the scene contains several items.
In the Media Source properties, select the local video file. OBS supports several common formats, including MP4, MOV, MKV, and WebM, as described in its Media Sources documentation. Choose the file from the computer where OBS is running, not a file that only exists on another computer or inside a disconnected drive.
Turn on Loop. OBS documents this option as playing the file again after playback completes. Without it, the source reaches the end of the file and stops. The preview may still show the last frame, which can make the scene appear present even though no new motion or audio is being sent from the source.
Review the other source properties before closing the window. If the file contains audio, confirm that the source’s audio is visible in the OBS mixer when the file is playing. If the video does not fit the canvas, use the normal transform controls to position or scale it. Do not confuse a visual scaling problem with a looping problem: a file can repeat correctly while appearing cropped or surrounded by empty space.
Play the source in the preview and wait long enough to observe its end. A short test file makes this easier than testing a programme that runs for hours. Watch for a clean restart, a brief pause, a missing audio return, or a source that remains frozen on its final frame. If the file behaves incorrectly before you connect to YouTube, sending it to a live broadcast will not make the source more reliable.
For a channel that must run from a spare computer, remember that this arrangement still depends on OBS, the local file, the computer, and the connection remaining available. The loop setting controls what happens when the file reaches its end. It does not promise that the whole operating setup will remain running indefinitely. If the computer is part of your plan, the guide to running a nonstop YouTube stream from a spare PC covers the wider operating trade-offs.
Loop several files with a VLC Video source
Use a VLC Video source when you want OBS to play an ordered sequence of separate local files. This suits a channel with several bhajans, a set of short news segments, a rotation of study scenes, or a collection of ambience clips that should play one after another.
The VLC Video source requires VLC Media Player to be installed on the same computer as OBS. OBS also specifies that a 64-bit OBS installation requires 64-bit VLC. Install the matching VLC version before troubleshooting the playlist itself. If OBS cannot use VLC correctly, the problem may be the installation or architecture rather than the order of the files.
In your broadcast scene, add a new source and select VLC Video. Add the local files to the source playlist. Arrange them in the order in which they should appear. The playlist is not the same thing as a YouTube playlist: it is a list of local files that VLC and OBS use as the production source.
Enable Loop Playlist. OBS documents this option as restarting the source after it has run out of media files, and its documented default is On. Check it rather than relying on a default, especially if you are opening an existing scene, importing a scene collection, or moving the setup to another computer.
Play through the end of the sequence during testing. Confirm that the first file starts again after the final file, rather than the source stopping, showing a blank frame, or returning to only one item. Check both video and audio at the transition between files. Different files may have different aspect ratios, audio levels, frame rates, or opening delays, so an ordered playlist can expose problems that do not appear with one file.
If your files are stored on removable media, test with that storage connected in the same way it will be during the real broadcast. A playlist entry that points to a missing or renamed file cannot play it. Keep the files in a stable location and avoid reorganising folders after you have built the source.
For a 24/7 channel, a sequence of smaller files is easier to rearrange than one large file, but it creates more transitions to inspect. One long file reduces the number of hand-offs between media items, while several files make it easier to remove a segment or change the running order. Neither choice removes the need to test the complete scene.
Set playback order and loop behaviour
The file order is part of the programme design. Put the files into the VLC playlist in the order viewers should receive them, then review the list from top to bottom. Use descriptive filenames or a written running order so that a later edit does not accidentally place an advert, announcement, or closing card in the wrong position.
A simple comparison can help you choose the source type:
| Requirement | OBS Media Source | OBS VLC Video source |
|---|---|---|
| Number of files | One local file | An ordered sequence of local files |
| Repeat setting | Loop | Loop Playlist |
| VLC installation | Not required for this source | Required |
| Main check | The file restarts after its end | The first file returns after the last file |
| Scene visibility concern | Review if the source is hidden during scene changes | Review visibility behaviour particularly carefully |
For one file, the key event is the return from the end of the file to its beginning. For several files, there are two events to check: the hand-off from each file to the next and the return from the last file to the first. Listen as well as watch. A sequence can look continuous while its audio drops at every transition.
Do not assume that a YouTube playlist and an OBS VLC playlist stay synchronised. They are separate lists managed in different places. The YouTube playlist may organise a page for viewers, while the VLC playlist determines the media that OBS sends into the live broadcast. Changing one does not reorder the other.
If your channel publishes recorded religious services or other prepared programming, review the material before putting it into a continuous loop. The guide to streaming a recorded Sunday service as live discusses the production questions around recorded programming. You should also confirm that you have the necessary rights and that the content follows YouTube’s current rules; a loop setting does not change those obligations.
Add the source to the streaming scene
A correctly configured source still has to be visible in the scene that OBS is sending. In the Sources panel, check that the Media Source or VLC Video source is enabled and placed above any item that could cover it. A source can be playing in OBS while viewers see a full-screen image, browser source, or another video layered on top.
Use the preview to confirm the intended framing. Right-click the source or use the transform controls to fit it to the canvas if necessary. Check that text near the edges is not cut off and that the important part of a vertical or square video is not hidden by the scene layout.
Pay close attention to Visibility Behaviour. OBS documents the VLC source default as Stop when not visible, restart when visible. If you switch to another scene, the source may stop when hidden and restart when it becomes visible again. That can reset a playlist unexpectedly, interrupt a programme, or make it appear that the loop has failed.
If the source must continue through scene changes, review the visibility behaviour in the source properties and test the exact transitions you intend to use. For example, switching from a main programme scene to a brief announcement scene and back is not the same test as leaving the programme scene visible all night. The scene design and the source’s visibility setting need to agree.
Keep the setup simple if there is no operational reason to change scenes. A single scene containing the looping source has fewer visibility transitions to troubleshoot. If you need an announcement, schedule, or camera scene, write down when it should appear and test returning to the loop afterwards.
For a channel that should operate without your main computer being left on, an upload-and-run workflow can remove the need to maintain a local OBS session. StreamNeo turns an uploaded file into a YouTube-only live stream after you paste in the YouTube stream key, so the particular pain it removes is keeping the local playback computer running and watching for a dropped broadcast. It does not change the need to check your content rights or YouTube’s rules.
Connect OBS to YouTube Live
Once the local source plays correctly, connect OBS to YouTube. In YouTube Studio, create or open the live stream workflow and obtain the stream details shown for the broadcast. YouTube’s official live streaming guide explains the platform-side process.
In OBS, open the stream settings and choose YouTube if it is available in the service list, or use the server and stream key supplied by YouTube. Paste the key carefully. A missing character, extra space, or key belonging to a different broadcast can prevent the connection even when the video source is configured correctly.
Treat the stream key as private. Anyone who obtains it may be able to send content to the associated live stream, so do not publish it in screenshots, documents, or chat messages. If you think it has been exposed, use YouTube’s current controls to replace or reset it rather than continuing to use a key you no longer trust.
Start with the OBS preview and local playback, then begin the connection according to the YouTube and OBS workflow. Watch both sides: OBS should show an active connection and YouTube Studio should show the incoming broadcast. A source looping locally is not proof that YouTube is receiving it.
YouTube may show a delay between the encoder and the public watch page. That is normal for a live workflow, but it makes testing more deliberate. Use YouTube Studio’s preview or monitoring view where available, then check the public watch page as a viewer would. Do not make repeated changes based only on the first few seconds of the public player.
If the stream key is rejected, separate the connection problem from the media problem. First confirm that OBS can connect with the chosen YouTube settings. Then confirm that the expected scene is being sent. For key-related troubleshooting, see this guide to fixing YouTube stream key errors on a 24/7 Indian music channel. It is easier to diagnose one layer at a time than to change the key, source, scene, and files together.
Check playback before going live
Run a short end-to-end test before committing to an unattended broadcast. OBS recommends a test stream in its quick-start guide, and the same principle applies whether your channel is a local news loop, a study station, or a devotional programme.
The test should cover the actual path: local file, OBS source, scene, YouTube connection, and viewer playback. If you use a VLC playlist, let the test reach the end of the list when practical. If the files are long, use a short copy or a small test playlist that still reproduces the transitions you need to inspect.
Check these points during the test:
- Does the first file begin with both picture and sound?
- Does one Media Source return to its beginning after the file ends?
- Does a VLC Video source move through every file in the intended order?
- Does the final file return to the first file when Loop Playlist is enabled?
- What happens when you hide the source and show it again?
- Does changing scenes stop, restart, or preserve playback as you intended?
- Is the source visible in the scene that OBS is sending?
- Does YouTube receive the same picture and audio that OBS shows?
- Does the public watch page continue past the first source cycle?
Make a note of the time at which each file begins. This gives you a practical way to compare the planned order with what a viewer receives. It also helps identify whether a pause happens at a file transition, a scene change, or the YouTube delivery stage.
Watch the audio meter throughout the test. A frozen image is obvious, but silent audio can be missed if you are looking only at the preview. Check for audio that starts late, disappears at a transition, or is too quiet compared with the preceding file.
Only after the test should you leave the channel running without active supervision. A successful loop test confirms the configured playback behaviour under those test conditions. It does not guarantee that the computer, encoder, network connection, or broadcast will remain available indefinitely. Plan how you will notice a failure and who will check the channel if the normal operator is unavailable.
If you are deciding whether to keep a local computer running at all, compare the operational trade-offs with 24/7 streaming without a PC. The right choice depends on whether you need live scene changes, how often the files change, who will maintain the setup, and whether the broadcast must continue when your computer is switched off.
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’s Loop button repeat my OBS source?
No. YouTube’s Loop control repeats playback for the viewer using YouTube’s player. It does not configure OBS or make a local Media Source or VLC Video source repeat.
How do I loop one video file in OBS?
Add the file as a Media Source and enable Loop in its properties. Test the source until it reaches the end and begins again, then confirm that the source is visible in the scene being streamed.
How do I loop several files in order?
Add a VLC Video source, add the local files to its playlist in the required order, and enable Loop Playlist. VLC Media Player must be installed, and OBS’s documented architecture requirement means 64-bit OBS needs 64-bit VLC.
Why did my VLC playlist restart after changing scenes?
OBS documents the VLC source default as stopping when it is not visible and restarting when it becomes visible. Review the source’s Visibility Behaviour and test the scene changes you plan to use before running the broadcast unattended.
