For one local mantra file, use OBS Media Source and enable Loop. For a collection of files, use VLC Video with Loop Playlist enabled; VLC must be installed, and its bitness must match OBS.
Before relying on either setup for a 24/7 YouTube broadcast, test playback, audio and the outgoing preview. Confirm you have permission for live and archived use of the exact recording, and do not count on YouTube to save a stream that runs longer than 12 hours.
Choose one file or a playlist
Start by deciding what should repeat. If one continuous mantra recording, perhaps with a still image or a long visual sequence, is all you need, a single local file in Media Source keeps the setup straightforward. OBS repeats it when it reaches the end. That is a good fit when the file itself contains the complete programme you want viewers to hear and see.
If you want several recordings to play in sequence, use VLC Video. It gives OBS a list of local media files and has a Loop Playlist setting for starting the rotation again when the last item finishes. You can also choose whether to shuffle. That gives you more control over a collection, but introduces a VLC installation and another playback component to check.
| OBS source | Best fit | Main setting | Trade-off |
|---|---|---|---|
| Media Source | One local audio or video file | Loop | Fewer moving parts; plays one item at a time. |
| VLC Video | A set of local files | Loop Playlist; optionally Shuffle Playlist | Playlist controls; VLC must be installed and compatible. |
Neither choice guarantees gap-free transitions or uninterrupted broadcasting. A file can have silence at its end, an inconsistent audio level, or a visual that changes abruptly when it restarts. A multi-file rotation can expose differences in loudness, duration and format. Listen and watch through the transitions on the actual OBS setup you plan to use.
Keep the playlist files together in a stable local folder and use files you have checked. Renaming, moving or deleting a source file after setting it up can leave OBS unable to play it. For practical context on a different route to a continuous devotional broadcast, see this Tamil devotional stream setup guide; here, the choice is specifically between OBS’s single-file and VLC playlist sources.
Install and check VLC compatibility
You do not need VLC for a single Media Source file. You do need VLC installed if you want to use OBS’s VLC Video source. OBS’s VLC Video Source documentation notes that VLC must be installed for the source to be available, and that a 64-bit OBS installation requires 64-bit VLC. Check the OBS version before installing VLC rather than assuming the applications will match.
After installation, close and reopen OBS if VLC Video does not appear in the Sources menu. If the source is still missing, check that the VLC installation and OBS are both 32-bit or both 64-bit. Do not treat a missing source as a playlist configuration problem until you have checked this dependency.
For a one-file setup, skip this dependency entirely: add Media Source and test whether the selected file opens. OBS supports common local audio and video formats, including MP3, WAV, MP4, MKV, MOV and WebM, though support for a format does not ensure that every file encoded in it will behave well on your machine. If a file fails or has no sound, try a known-good copy in a supported format and inspect the source settings.
Keep the playback source visible in the active scene during your test. OBS sources can have behaviour tied to whether they are active or hidden: Media Source can restart when activated, while VLC Video can be configured to stop when hidden and restart when visible. If you switch between scenes, check those settings and observe what happens rather than assuming playback continues in the background.
Add an OBS Media Source and enable Loop
Open the scene that will carry the broadcast. In the Sources dock, select the plus button, choose Media Source, give it a recognisable name such as “Mantra master”, and confirm. Choose Local File, browse to the recording, and select Loop. OBS describes Loop as replaying the media when playback ends; the source’s other options can affect how it starts and behaves when activated.
If the file includes video, make sure it fits the canvas as intended. A still image paired with audio can also be used, but configure the picture and audio as separate sources if that gives you the control you need. Preview the whole scene, not just the media source properties: a source may be behind another layer, hidden, cropped or positioned outside the visible area.
For an audio-only file, watch the OBS audio mixer while it plays. A moving meter indicates that OBS is receiving audio from the source, but it does not prove the stream audience can hear it. That is why the test must continue through the stream output or destination preview. Also listen for clipping, abrupt cuts at the loop boundary, long silences or a level that is too low to hear clearly.
The source’s restart-on-activation behaviour matters if you use multiple scenes. If switching back to the scene restarts the track, viewers may hear the opening again rather than the point where it was. Keep the source in a scene that remains active when you need uninterrupted playback, or test the precise scene transitions you intend to use.
OBS is a local encoder, so the computer, power, network and application all remain part of the chain. This is different from an arrangement in which you upload a file once and do not leave your computer running. If the difficulty you are trying to solve is keeping a local machine on overnight, StreamNeo removes that particular computer-running burden by taking an uploaded video and broadcasting it to YouTube; it does not change the need to choose content you have rights to use.
Build a VLC playlist and enable Loop Playlist
For multiple files, add VLC Video from the Sources dock and open its properties. Add the local files you want in the playlist, arrange them in the intended order, then enable Loop Playlist. If you prefer the order to vary, use Shuffle Playlist and check the resulting playback rather than assuming it will alternate in a particular pattern.
Use clear file names and keep a written order if sequence matters, for example opening chant, longer recitation, then closing chant. Check each item individually before building the rotation. A playlist is only as dependable as its paths: moving a file or changing a folder can break an entry. Keep the files available to the account and computer that run OBS, and avoid relying on removable storage that may be disconnected.
Listen across every transition. Files can differ in loudness, encoding, silence at the beginning or end, and length. Loop Playlist controls what happens after the list finishes; it does not promise a seamless hand-off between items. If you need a specific flow for a devotional service, curate the files and transitions before the stream rather than expecting the playlist control to fix the material.
Do not assume a YouTube playlist page or URL is the documented source for this OBS feature. The workflow here uses local files in VLC Video. If your goal is to schedule different prerecorded segments by time or trigger, that is a separate problem from looping a playlist; this guide on playing different prerecorded videos during a YouTube Live stream covers that distinction.
Test media, audio output and stream preview
Use a short preflight before going live. OBS’s Quick Start Guide recommends testing settings and running a short test stream before a real broadcast. Check the source plays from the beginning, reaches its end and loops as expected; for VLC Video, test the end of the list and the return to the first item. Confirm any scene changes do not unexpectedly stop or restart it.
Next, inspect the audio mixer while the mantra plays and listen to the computer’s output. Make sure the intended source is not muted, that the level is audible without distortion, and that any desktop audio you do not want is not being sent as well. A mixer meter is useful but is not a substitute for listening to the encoded result.
Run a private or otherwise controlled test using the destination and settings you intend to use. Check the YouTube stream preview for both picture and sound, and check the broadcast from a separate playback device if you can. This can reveal a mismatch between what OBS displays locally and what reaches YouTube. Do not begin a long public session until you have seen and heard the outgoing signal.
A 24/7 stream also depends on the computer remaining powered, OBS staying open, the network remaining available and the platform accepting the broadcast. YouTube recommends leaving upload capacity above the total stream bitrate; its streaming tips specify 20% headroom. Treat that as room for the connection, not a guarantee against dropouts. Settings that work on one computer or network may fail on another, so test the actual machine, scene complexity, resolution and frame rate you will use.
During the broadcast, monitor for a frozen picture, silent audio, disconnection or a source that has stopped. Automatic reconnect settings can help OBS recover from some interruptions, but they do not remove the need to check whether the stream resumed correctly. If uninterrupted operation matters, decide who will check it and what they should do after a failure. A local OBS loop is not a promise of continuous uptime.
Confirm music rights for live and archived use
A devotional subject does not make a recording free to rebroadcast. The composition, a particular performance, the recording and any accompanying visuals can have different rights holders. Having a copy of a track, finding it online, or crediting the singer does not by itself establish that you may transmit it to a live audience or retain a replay.
Check permissions for the exact recording and for the uses you intend: live streaming, any local recording, and any YouTube archive that may be created. YouTube’s live-streaming terms state that creators represent they have the necessary rights for live content, including applicable music licensing rights. If a rights holder or distributor has granted permission, keep the terms and any relevant correspondence accessible.
YouTube also says it scans live streams for third-party content. Its copyright guidance for live streams explains that a stream may be interrupted or replaced with a placeholder when third-party content is detected. Even licensed content may require the rights owner to allowlist your channel through Content ID. Ask the licensor what is required for your channel and confirm the arrangement before the broadcast.
Rights for the live use and for an archive are not necessarily identical. A permission that covers a live transmission may not cover an enduring recording, and a platform’s ability to create an archive does not grant rights to keep it. Confirm both uses with the relevant rights holder, or arrange the broadcast so that you do not rely on an archive you cannot lawfully retain.
Understand YouTube’s long-stream archive limit
Do not plan a 24-hour YouTube broadcast on the assumption that the whole programme will become a replay. YouTube says streams shorter than 12 hours can be automatically archived, but streams longer than 12 hours may not be captured at all. The threshold is an archive caveat, not a promise that every shorter stream will produce a complete replay.
If a replay matters, consider ending and restarting as shorter sessions, while taking account of how that affects viewers and any scheduled programming. Alternatively, make a local recording and verify that the recording is being written and remains playable. YouTube’s guidance on live stream archives advises checking that a local archive file is growing when recording locally. A file that appears in a folder is not enough; confirm its size changes during the test and that it opens afterwards.
Shorter sessions and a local copy each involve work. Session breaks require someone to manage the broadcast and may interrupt viewing; local recording uses storage and also needs monitoring. Decide what matters most: a continuous live feed, a usable replay, or both. If both matter, test the session plan and the recording workflow before relying on them.
For a continuous channel, separate the live operation from the archive plan. The stream can continue while the archive is split into sessions or captured locally, but those are additional choices to configure and verify. See this guide to scheduling YouTube Live redirects for an Indian 24/7 music channel if you need to plan how viewers move between live sessions; it does not change YouTube’s archive behaviour.

FAQ
How do I loop one mantra recording in OBS?
Add a Media Source, choose the local file and enable Loop in its properties. Test the end of the file and confirm it starts again, with the source active in the scene you will use.
How do I loop several local files in OBS?
Install VLC with the same bitness as OBS, add VLC Video, build the local-file playlist and enable Loop Playlist. Play through the transitions and confirm the list returns to its first item as expected.
Will YouTube archive a 24-hour livestream?
Do not rely on it. YouTube says streams longer than 12 hours may not be captured at all, so use shorter sessions or maintain and verify a local recording if the replay matters.
Does a mantra recording count as free to rebroadcast?
Not automatically. Confirm that you have the rights for the exact recording and for both live use and any archive, and check whether the rights holder needs to allowlist your channel.
