If you want to stream a music playlist 24/7 on YouTube using OBS, add the playlist through OBS's VLC Video source and enable Loop Playlist. The playlist can then return to its first file when the last one finishes, but the broadcast still depends on your computer, power, internet connection, files and stream health.
VLC is not optional for this particular OBS source. Install the correct VLC version first, then prepare music you are allowed to broadcast, build the scene, connect YouTube and test the full cycle before leaving it unattended.
Install VLC before opening the playlist source
OBS Studio's VLC Video source uses VLC components. If VLC is not installed, the source may not appear in OBS's source list, so installing OBS alone is not enough for this workflow. Download VLC from the official VLC site and install it before configuring the scene.
The OBS documentation says the VLC Video source is available on Windows, macOS and Linux. It also specifies that a 64-bit OBS installation needs 64-bit VLC. Check whether your OBS installation is 64-bit and match the VLC installation to it rather than assuming that any VLC installer will do.
After installing VLC, restart OBS if it was already open. Create or open a test scene, select the plus button in the Sources dock and look for VLC Video. You do not need to add files yet. The purpose of this first check is to confirm that OBS can see the VLC installation before you spend time arranging the broadcast.
If VLC Video is missing, close OBS completely and open it again. Check the installed VLC architecture, then confirm that VLC launches normally. Avoid trying to solve this by adding a different media source: a normal Media Source is designed around a single file and its Loop control, whereas the VLC Video source is the documented OBS option for a playlist.
Prepare music files you can actually broadcast
Put the playlist files in a dedicated folder before adding them to OBS. A simple folder such as YouTube Music Stream makes it easier to find the files, back them up and check that every item remains available after a restart. Do not scatter the playlist across Downloads, removable drives and cloud-synchronised folders unless you have a clear reason to do so.
OBS's media documentation lists common audio formats including MP3, AAC, OGG and WAV. Use files that play correctly in VLC before importing them into OBS. Open each file, listen for silence or a damaged ending, and check that the filename describes the intended track. A file that fails in an ordinary player is not a good candidate for an unattended broadcast.
Rights need checking before technical setup. Music being available online, purchased, downloaded or playable in a personal account does not by itself give you permission to retransmit it publicly on YouTube. Confirm that your permission covers a live YouTube stream and, if you intend to keep an archive or replay, the archive as well. For a music channel, YouTube for Artists' guidance on going live recommends coordinating with the relevant label or distributor when using copyright-protected music.
YouTube says that live streams are scanned for third-party material. Its guidance states, “All live streams are scanned for matches to third-party content, including copyrighted content in the form of another live broadcast.” A match can lead to an interruption or termination. Even where you have a licence, YouTube explains that the rights owner may need to add your channel to its Content ID allowlist. Keep written confirmation of the rights and any allowlisting request rather than relying on the fact that a track plays on your computer.
The copyright and Content ID explanation for live streams is useful background, but the current YouTube policy page remains the source to check before broadcasting. Rights vary by territory and by use, so a licence for personal listening, an upload or an in-person event may not cover a continuous YouTube broadcast.
Now test the complete folder in VLC. Play files from the beginning and near the end, check that the audio is not clipped and note whether any track has an unusually long silence. If your visual layer will show track names, make sure the names are suitable for a public page and do not contain private notes or unfinished labels.
Add VLC Video to your OBS scene
Open OBS and select the scene that will carry the broadcast. In the Sources dock, select the plus button and choose VLC Video. Give the source a clear name, such as Music playlist, so it is easy to identify when you return to the scene later.
The source properties include a playlist area where you can add multiple media files. Add the files from the prepared folder and review the order. If order matters, place them deliberately rather than assuming that the file browser will sort them in the order you want. A numbered naming system such as 01, 02 and 03 can make the intended sequence easier to inspect.
A music-only source may not create a useful viewer experience by itself. Add a visual layer appropriate to the channel, such as a static image, a licensed artwork panel or a simple visualiser that you have tested in OBS. Sources are layered in a scene, so a source above another can cover it. The OBS Sources guide explains how sources are added and ordered.
For example, you might place a background image at the bottom, a visualiser above it and the VLC Video source in the scene. If the visualiser is intended to react to the music, confirm that it receives the same audio source rather than an unrelated desktop signal. Keep the design readable at the output resolution and remove elements that could expose personal notifications, desktop windows or other private information.
The VLC Video source also has visibility behaviour settings. Decide what should happen when the source is not visible: it can continue, pause or stop according to the available control. For a single broadcast scene, this may not change anything. It matters if you switch to another scene during an intermission or keep several scenes available, because the chosen behaviour can affect where the playlist is when you return.
Load the playlist and enable Loop Playlist
In the VLC Video source properties, add all the files that belong to the rotation. Then enable Loop Playlist. This is the control that tells the source to start the playlist again after the final item. Without it, playback can reach the end and remain stopped even though OBS and the YouTube broadcast are still connected.
Do not confuse Loop Playlist with the single-file Loop control in OBS's Media Source. A Media Source can repeat one file, while VLC Video is the relevant source when you need several files in a playlist. The distinction matters for a devotional loop, a study station with several ambience tracks or a local music sequence.
Decide whether the rotation should be ordered or shuffled. Shuffle Playlist changes the order instead of preserving the list. Ordered playback is easier to audit and is useful when the programme has a deliberate progression. Shuffle can make a long collection less predictable, but it also makes it harder to tell which file should play next when you are testing a problem.
For a first unattended run, keep shuffle off and use a short, clearly labelled test playlist. Start with two or three files that you are authorised to use. Watch the first file reach its ending, confirm that the next file begins, then let the final file end and verify that the first file starts again. Expand the playlist only after that cycle works.
If a file is moved or renamed after it has been added, OBS may no longer be able to find it. Keep the folder structure stable. If you migrate the playlist to another computer, open the source properties and check every path instead of assuming that the files will be rediscovered automatically. A missing item can create silence or an incomplete rotation while the scene itself looks normal.
Set up the YouTube live event and stream key
YouTube's encoder workflow lets OBS send the programme to a YouTube live broadcast. Before relying on it, check the current requirements in YouTube Help's live-streaming guide. The research for this setup notes that the channel must be verified and must not have a live-stream restriction in the previous 90 days, but eligibility and the Studio workflow can change.
In YouTube Studio, create or schedule the live event and choose the encoder method. YouTube will provide the stream settings, including the stream key. Treat the key as a password: do not publish it in a screenshot, paste it into a public document or send it in a chat that does not need access.
In OBS, open Settings, then Stream, and choose the YouTube service if it is available in your installation. Sign in through the supported flow or enter the stream key supplied by YouTube. Use the current YouTube Studio instructions if the labels in OBS or Studio differ from these steps. Do not copy a stream key from an old event unless you have checked that it is the key for the event you intend to use.
The event title, description, thumbnail and visibility are separate from the local playlist. Set them in YouTube Studio and verify whether the event is public, unlisted or private before starting. A private test can reveal problems with the scene and audio without promoting an unfinished broadcast, although the account still needs to meet YouTube's live-stream requirements.
A stream key connects OBS to the channel, but it does not grant music rights and it does not make the stream immune to platform action. Check YouTube's copyright guidance for live streams before starting a music broadcast. If the material is licensed, confirm any additional channel allowlisting requirement with the rights owner or distributor.
Test audio, video and playlist cycling
Before you leave the stream running, test the complete route from file to viewer. In OBS, confirm that the scene preview shows the intended visual layer and that the audio mixer meter moves when the music plays. If the meter is silent, first check that the VLC source is not muted and that the selected files contain an audible track.
Use headphones or another device to listen to the YouTube output rather than trusting the OBS preview alone. The local preview can sound correct while the live output has an incorrect source, excessive volume or a missing visual layer. Keep the monitoring volume moderate and check for clipping during louder passages.
Run a short private or unlisted test. Confirm these points:
| Check | What to verify | Why it matters |
|---|---|---|
| VLC source | Every intended file is listed and playable | A missing path can shorten the rotation |
| Loop Playlist | The first item returns after the final item | The playlist otherwise stops at its end |
| Audio meter | Music reaches the intended OBS source without clipping | A visible scene can still be silent |
| Scene preview | The artwork or visualiser is visible and unobstructed | Sources can cover one another |
| YouTube output | The viewer-side stream has picture and sound | Local preview is not the complete path |
| Stream status | OBS and YouTube both show an active connection | A scene can play locally without a healthy broadcast |
Let the test continue long enough to reach a file transition. If your files are lengthy, use a small test playlist with short, authorised clips rather than waiting for an entire programme. Check the transition for a gap, abrupt cut or change in loudness. A clean transition is useful, but it does not prove that every file in a larger collection is healthy.
Watch the YouTube Live Control Room while the test is running. Look for warnings, stream health messages and a stable preview. Keep OBS's status area visible as well. If either side reports a problem, stop and identify it before promoting the event. This is a test of the path, not a guarantee that the stream will remain live through every future night.
A useful test also includes a deliberate restart. Stop OBS, reopen the project and confirm that the VLC source still points to the files. Then start again and make sure the intended scene is selected. This catches problems that only appear after a reboot, a software update or a change in the working folder.
Understand what 24/7 operation requires
OBS can play and send the playlist, but OBS alone does not guarantee a 24/7 YouTube stream. The computer must stay powered on, remain connected to the network and continue running OBS. A power cut, forced operating-system restart, overheating, a failed drive or an interrupted connection can stop the broadcast even when Loop Playlist is configured correctly.
Set the computer not to sleep while the channel is running. Review automatic updates and restart behaviour, but do not disable important security updates without understanding the risk. If the machine is a shared household computer, another user can close OBS, change the audio output or start a demanding application. A dedicated computer is not required by this setup, but the machine you use must remain available and predictable.
Keep the playlist on reliable local storage. Avoid disconnecting an external drive while the stream is live. Make a backup of the source files and the OBS scene configuration. If a file is corrupted, a backup lets you replace it and update the playlist rather than rebuilding the entire scene from memory.
Monitor the network connection, not only the speed test you ran during setup. A connection can appear fast and still drop packets or disconnect overnight. If possible, use a stable wired connection and keep the router powered. Do not treat this as an uptime promise: it is simply a way to remove one avoidable failure point.
Check the broadcast at intervals, especially after the first unattended run. Look at the public YouTube page or Live Control Room, the OBS stream status and the audio meter. A stream can remain connected while the wrong scene is visible, the playlist has stopped or the audio has become silent.
For a channel that cannot keep a computer running, a hosted workflow may remove the local power and network dependency. It changes the operating model rather than making the files or rights problem disappear. You still need a stable playlist, permission to broadcast the music, a working YouTube connection and a process for checking the live output. The pre-recorded streaming workflow without a PC running explains the different trade-off for readers considering that kind of arrangement.
The same principle applies to channel planning. A music station may benefit from a suitable visual identity, while a regional devotional channel may need several language-specific rotations. The Tamil and Telugu devotional loop guide covers that programming question separately. If you are still deciding whether a camera is necessary, these 24/7 channel ideas without a camera can help you choose a format before you build the scene.
If your main problem is leaving a local computer powered and monitored, StreamNeo removes that particular burden by turning an uploaded video into a YouTube live stream that can continue while your computer is switched off. You still need to prepare the file, hold the relevant rights and check the current YouTube requirements, but the local OBS machine is no longer the part you have to leave running.

FAQ
Can OBS loop an MP3 playlist without VLC?
Not through the VLC Video source. Install VLC first so OBS can provide that source, then add the files and enable Loop Playlist. OBS's Media Source can repeat one file with its own loop control, but that is a different setup from a multi-file VLC playlist.
Does Loop Playlist keep YouTube live all day?
It only controls what happens when the playlist reaches its final item. The computer, power, network, OBS process, local files and YouTube connection still need to keep working. Test the complete route and monitor it rather than treating the loop setting as an uptime guarantee.
Can I use music I bought for a 24-hour YouTube stream?
Personal purchase or playback access does not automatically cover public live retransmission. Confirm that the rights include YouTube live streaming and any archive, and check whether the rights owner must allowlist your channel through Content ID. YouTube can scan, interrupt or terminate a live stream when it detects third-party material.
Should the playlist be ordered or shuffled?
Use ordered playback when you need a predictable programme and easier troubleshooting. Shuffle is available when a less predictable rotation suits the channel, but it makes it harder to identify the next file during a test. Start ordered, prove the loop works, then decide whether shuffle serves the format.
