If you want several local video files to repeat during a YouTube Live broadcast, add them to OBS as a VLC Video Source and enable Loop Playlist. YouTube’s own Autoplay or loop control is for playback on a viewer’s device, not for sending a playlist into a live broadcast.
You can still use YouTube Autoplay when checking a playlist on a computer or phone, but it should not be treated as error recovery. For a dependable live setup, configure the playlist in OBS, test the files, connect OBS to YouTube Studio, and monitor the stream before leaving it running.
Turn on Autoplay on the device playing the playlist
Start by separating two workflows that are often confused. If you are watching a playlist on YouTube, Autoplay controls what the YouTube player does after the current video finishes. If you are broadcasting local files through OBS, the OBS source controls the order and repetition of those files.
To try Autoplay in YouTube, open the playlist on the device that is actually playing it. Start one item and turn on the Autoplay switch in the player. On a desktop browser, the switch is normally near the video player controls. On a phone or tablet, it is available in the YouTube app’s player or playlist interface, although the exact position can vary with the app version and screen layout.
With Autoplay enabled, YouTube can continue to the next item when the current item ends. This is useful for checking whether the playlist order and programme content make sense before you prepare a broadcast. It is also useful when a channel owner is monitoring a public playlist from another device.
Autoplay does not turn a YouTube playlist into an OBS input. It does not send the playlist to YouTube Live, and enabling it in a browser does not make an OBS broadcast continue. For the live stream itself, the files must be played by an OBS source, and OBS must send the resulting video and audio to YouTube through an encoder connection.
If your intended source is an existing YouTube playlist rather than files stored on your computer, that is a different arrangement. YouTube’s playlist loop guidance concerns viewer playback. It does not replace the OBS setup described below.
Find the control on desktop or mobile
On a desktop browser, open the playlist and select an item. Look around the YouTube player for the Autoplay toggle, then play the next item far enough to confirm that it is active. The playlist panel may show the sequence, but the setting belongs to the playback session and device, not to every person who opens the playlist.
On Android or iPhone, open the playlist in the YouTube app, select a video, and look for the Autoplay control in the player or playlist view. If you cannot see it, expand the player or open the playlist controls. YouTube changes its interface from time to time, so use the current control shown by the app rather than relying on an old screenshot.
The important test is not simply whether the switch looks enabled. Let one item finish, or move close enough to the end to observe what happens next. Check that the following item is the one you expect, that the phone or computer remains connected, and that audio is coming from the device you intend to monitor.
For a public live channel, do not use a phone’s YouTube player as the main loop mechanism unless you have deliberately chosen a viewer-playback workflow and understand its limitations. A phone can lock, lose its connection, change networks, receive an interruption, or stop playing when the app is not active. Those are playback concerns, separate from the encoder process that sends a live signal.
If you are comparing a computer-based arrangement with another operating method, the practical trade-offs are set out in OBS on a spare PC versus a VPS. The relevant question is not only whether a file can repeat, but what happens when the computer, connection, or player needs attention overnight.
Check the device actually playing the playlist
Autoplay is local to the playback experience. If you enable it on your phone, that does not enable it on your desktop browser. If you open the playlist in a browser while OBS is playing local files, you have enabled a setting on the browser, not on the OBS source.
Before troubleshooting, identify the actual playback path:
| Intended use | Device or software doing the playback | Setting that controls repetition |
|---|---|---|
| Watching a YouTube playlist | YouTube app or browser | YouTube Autoplay or playlist controls |
| Repeating one local file in OBS | OBS Media Source | Media Source’s Loop setting |
| Repeating several local files in OBS | OBS VLC Video Source | Loop Playlist |
| Sending the result to YouTube Live | OBS connected to YouTube Studio | OBS stream settings and YouTube Live Control Room |
This distinction prevents a common false fix. A creator sees that a playlist repeats in YouTube on a laptop, then expects an OBS scene on the same computer to broadcast that sequence. Unless OBS is capturing the browser and sending it as its live output, the two playback paths are unrelated. Even browser capture introduces its own risks, including notifications, page changes, resolution changes, and interruptions.
For local media, keep the files in a location that will remain available while OBS is running. Avoid renaming, moving, or disconnecting the folder after adding the files to the source. Check that each file has the audio and picture you expect. A playlist can technically continue while one item is silent, black, corrupt, or unsuitable for the channel.
The same check matters for a devotional stream, a local news loop, a study channel, or a small business information channel. Write down which file should play first, which order is intended, and whether the files contain their own audio. This gives you something concrete to verify instead of judging the setup only by the preview at the moment you start it.
Build the looping playlist in OBS
Install VLC before configuring the source. OBS documents that its VLC Video Source uses VLC libraries for extended media support. The OBS documentation also states that 64-bit OBS requires 64-bit VLC, so match the VLC installation to the architecture of OBS. If you install VLC while OBS is already open, close and reopen OBS before checking the source list.
In the OBS scene you intend to broadcast, select the + button in the Sources dock and add VLC Video Source. Give the source a name that identifies its purpose, such as “Night bhajan rotation” or “Morning news loop”. Add the local video files to the source playlist in the order you want them played.
In the source properties, enable Loop Playlist. Leave Shuffle Playlist disabled if the files need to play in a defined order. OBS lists shuffle as off by default, but inspect the control rather than assuming the default is still in place after editing the source.
The built-in OBS Media Source is different. It has a Loop setting for repeating one file. That is suitable for a single background video, a holding screen, or one long ambience file. It is not the same as a multi-file playlist. Use VLC Video Source when several files need to play in sequence and the sequence itself needs to repeat.
Resize the source in the scene and check the composition at the output resolution you plan to use. Watch enough of the opening and closing of a file to see whether the transition is acceptable. Confirm that the audio meter moves when audio should be present and that the monitoring device can actually hear it.
If the VLC Video Source option is missing, check that VLC is installed and that its architecture matches OBS. Reopening OBS is worthwhile after installation. If only one file repeats, check whether you accidentally added a Media Source instead of a VLC Video Source. If the playlist stops after its final item, return to the VLC source properties and inspect Loop Playlist.
For a related example of arranging several programme items in an OBS-based broadcast, see how to stream a podcast playlist on YouTube using OBS. The exact media and programme format may differ, but the distinction between an OBS playlist source and YouTube viewer playback remains important.
Connect OBS to YouTube Live
Once the scene plays correctly, configure YouTube as the destination. In YouTube Studio, open Create, choose Go Live, and create or select the live stream. In the encoder settings, copy the server URL and stream key into OBS’s stream settings.
Treat the stream key as private. YouTube describes stream keys as being like the stream’s password and address in its live stream settings help. Do not paste it into a public document, send it in a group chat, or include it in a screenshot. If you think it has been exposed, use YouTube’s current controls to replace or reset it.
Start streaming from OBS and wait for the live preview in YouTube Studio. For a scheduled stream, use the Live Control Room workflow to review the preview and go live when the signal is ready. YouTube’s encoder streaming guidance explains the current connection and preview process.
Do not treat the first successful preview as a full test. Let representative files play, including a file with speech, one with music, and one with the movement or graphics that your channel normally uses. Watch for silent sections, unexpected cropping, dropped frames, and a playlist that fails to move to the next item.
YouTube recommends testing before going live and monitoring stream health. Keep the Live Control Room open during the initial run if possible. A stream can look correct in OBS while the connection to YouTube is not behaving as expected, so check both sides of the workflow.
A bitrate and keyframe checklist can help when you are checking the encoder settings separately from the playlist. Do not change several settings at once. If the stream becomes unstable, you want to know which change affected it.
Use playback troubleshooting when an item errors
If an item fails while you are checking it in YouTube, use YouTube’s playback troubleshooting guidance rather than assuming Autoplay will repair the playlist. Check the connection, reload the player, update the app or browser where appropriate, and try the same item on the device that is meant to play it. YouTube’s video playback troubleshooting page is the appropriate starting point for current platform-specific steps.
Then inspect the item itself. A video may be private, removed, restricted in the viewer’s region, unavailable on a particular device, or affected by an account or app issue. The fact that the next item plays on one device does not prove that every viewer will receive the same result.
For an OBS playlist of local files, troubleshoot at the source instead. Confirm that the file still exists at its original path, opens in a normal media player, and has a format that VLC can read. Remove a damaged or unsuitable item temporarily and test the remaining sequence. If the problem follows one file, the file is a more useful suspect than the loop control.
Look at the OBS preview and audio mixer while the item is supposed to play. A black frame, frozen picture, or missing audio may be a source problem rather than a YouTube problem. If OBS itself stops sending, inspect the stream status in YouTube Studio and verify the server URL and stream key before rebuilding the playlist.
If a cloud reconnect or encoder restart is part of your wider plan, it is worth reading how to keep a YouTube loop stream running when a cloud service reconnects. Reconnection can restore a connection, but it does not automatically make a missing, corrupt, or unsuitable media item valid.
Understand what Autoplay does not promise
Autoplay moves playback to another item when the current item finishes under the conditions supported by the player. It is not a validation system for the playlist, and it is not a guarantee that every unavailable, restricted, or erroring item will be skipped.
An item may fail before it reaches its normal end. The player may show an error instead of completing the item, or it may stop because the network or app has a problem. In those cases, you should not assume that Autoplay will reliably advance to the next item. Test the actual playlist on the actual device and deal with failed items directly.
Autoplay also does not guarantee a continuous live broadcast. It cannot keep OBS open, restore a lost stream key, repair a local file, prevent a computer from sleeping, or maintain an internet connection. Nor does it turn viewer playback into a live encoder feed.
For a 24/7 channel, a local OBS arrangement gives you control over the files and scene, but it leaves the computer, power, operating system, storage, and internet connection in your operating plan. You may need to prevent sleep, keep the media folder available, check for system restarts, and decide who will respond if the stream needs attention.
A cloud workflow removes the need to leave your own computer playing the file. StreamNeo is designed for the specific hand-off where you upload the finished video, provide the YouTube stream key, and let the channel run while your computer is switched off, with automatic monitoring and restart if the broadcast drops. It remains a YouTube-only workflow, so you should still check the current YouTube requirements and your media rights.
Whether you use OBS locally or move the file to a cloud-based workflow, review the copyright guidance for a 24/7 YouTube music stream. A looping setup changes how content is delivered; it does not give you permission to use music, images, recordings, or broadcasts that you do not have the right to use.
Run a proper overnight test
Before making the stream public, run the exact scene and playlist you plan to use. Include the files most likely to expose a problem: a long item, a short item, a file with quiet audio, a file with movement, and the item that should play immediately after the loop returns to the first file.
Watch the OBS preview, the audio mixer, and YouTube’s stream health at the same time. Check that the first file begins as expected, that the order is correct, and that the final file returns to the first one. If the playlist uses shuffle, record the intended behaviour so an unexpected order is not mistaken for a failure.
Keep the stream key out of notes that are shared with helpers. If another person will monitor the channel, give them the minimum access needed and explain which screen shows the playlist, which screen shows the live status, and what should be recorded before making a change.
If the setup is running from a personal computer, consider what happens when the machine restarts after an update or loses power. A setup that works for an hour may still need an operating plan for the night. The multiple 24/7 YouTube channels from one PC guide is relevant if you are sharing one computer between channels, but do not assume that one computer can absorb unlimited scenes, media, or encoder work.
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 Autoplay loop a playlist inside OBS?
No. YouTube Autoplay controls playback in the YouTube app or browser on the device watching the playlist. For a local multi-file playlist in OBS, use a VLC Video Source and enable Loop Playlist.
Why does OBS repeat one file instead of the whole playlist?
You may have added OBS’s built-in Media Source, whose Loop control repeats one file. Add the files to a VLC Video Source and enable Loop Playlist when you need several files to repeat in sequence.
Will Autoplay skip every unavailable or erroring item?
No. Autoplay is not reliable error recovery and does not promise to skip every unavailable or erroring item. Test the playlist on the device that will play it and remove or fix failed items.
What should I check if YouTube shows no live preview?
Confirm that OBS is sending, then check the YouTube server URL and stream key. Keep the key private, and use YouTube Studio’s current encoder and live-control guidance to verify the preview before going live.
