For one local video that needs to repeat, use OBS Media Source and turn on Loop. For several files played as a playlist, use VLC Video; turn on Loop Playlist and leave Shuffle Playlist off if their order matters.
These settings control playback inside OBS, not YouTube's connection or the moment a scheduled stream becomes public. Media Source does not require VLC; VLC Video does. Choose the source for the job, then test the full broadcast separately.
Quick decision: one file or a playlist
The practical dividing line is the number of files and how you want them arranged. Media Source is the simpler choice for a single local video, such as a bhajan recording, an ambience loop, or a local shop's showcase. VLC Video is designed for a playlist, such as several devotional recordings or a sequence of recorded presentations.
| What you need | Choose | Check before going live |
|---|---|---|
| Repeat one local video | Media Source | Enable Loop in the source properties |
| Play multiple local files in sequence | VLC Video | Add files to its playlist and enable Loop Playlist |
| Keep a playlist in a fixed order | VLC Video | Leave Shuffle Playlist off |
| Change playback when a source is hidden | Either | Set and test that source's visibility behaviour |
A playlist is not automatically the better choice just because it can hold multiple files. If you have one carefully prepared long video, a playlist adds setup and another dependency without solving a problem. Conversely, if you want a rotating collection of separate files, repeatedly editing a single-file source is not the same as maintaining a playlist.
If you are planning an always-on broadcast from recorded material, the practical checks around source choice also apply to looping recorded conference presentations. The source selection is only one part of the broadcast: the video still needs to appear and sound as expected in the stream preview.
Media Source for repeating one local video
In OBS, add a Media Source and select the local file. In its properties, enable Loop if playback should start again after the file reaches its end. The setting belongs to that source and file. It is not a setting for the whole OBS scene or for YouTube.
Media Source is available in OBS on Windows, macOS, and Linux, and it does not require VLC to be installed. OBS documentation lists video formats including MP4, TS, MOV, FLV, MKV, AVI, GIF, and WebM, as well as audio formats such as MP3, AAC, OGG, and WAV. Whether a particular file plays cleanly is something to verify in your own OBS version and setup; a format name alone is not a test of the actual broadcast.
The Loop property is listed as off by default in OBS's documentation. Do not assume a newly added source will repeat without checking the property in the version you are running. OBS labels and defaults may change, so the settings in your installed application are the final check. See the OBS Media Sources documentation for the source properties and its documented formats.
Media Source also provides controls for what happens when a source becomes active or inactive. Depending on the source properties, you can restart playback when the source becomes active or close the file when it is inactive. These are useful when scenes change, but they alter local playback behaviour. For example, if a devotional channel switches between a main video scene and a holding scene, decide whether returning to the video should resume at its current point or begin again.
Test that behaviour by switching scenes before the broadcast. Watch the preview to see whether the source restarts, resumes, or has been closed. A loop that is correctly enabled does not, by itself, answer what should happen when the source is hidden and shown again. Those choices are separate properties and can matter as much as the repeat setting.
A single local file keeps the source setup straightforward, but it also makes that file the whole programme until you replace it or switch to another source. Make sure the file is the intended version, has the sound you expect, and is available on the computer where OBS runs. If you are deciding whether a local machine is a suitable basis for a continuous broadcast, compare the operational responsibilities in this guide to running a prerecorded YouTube stream on a mini PC in India; the source choice does not remove the need to consider the rest of the setup.
VLC Video for multiple files
Use VLC Video when you want OBS to play multiple files as a playlist. Add the files to the playlist in the order you intend, then check the playlist controls. Loop Playlist repeats the collection when it reaches the end. Shuffle Playlist randomises playback order, so leave it off when the sequence is part of the programme.
This is useful when a channel cycles through separate recordings rather than relying on one long render. A study channel might schedule several lessons in a set order, while a music channel might prefer a changing sequence. The playlist makes the collection visible as separate entries, which is convenient for editing, but it also means you need to check the entries, order, and playback options rather than just one file path.
OBS documentation lists Loop Playlist as on by default for VLC Video, unlike Media Source's documented Loop default. The upstream source implementation also sets shuffle off by default. Treat those as documented defaults, not a reason to skip inspection: confirm both properties in your own OBS installation before relying on a particular sequence. The OBS Sources Guide explains how sources fit into scenes and output; it does not make playlist settings a YouTube go-live control.
VLC Video offers visibility behaviour for when the source is not visible in the current scene. Depending on the selected behaviour, playback can stop and restart, pause and resume, or continue even while the source is hidden. Choose deliberately. If you want a hidden video to carry on so it is at a later point when shown again, continuous playback may fit. If switching away should stop the programme, choose and test a behaviour that does that. The visible source behaviour is local to OBS and should be tested in the actual scene arrangement.
The playlist approach brings a dependency: VLC must be installed for the VLC source to appear in OBS. That requirement is specific to VLC Video. It does not apply to Media Source. For a multi-file setup, the playlist convenience is worthwhile only if you are willing to keep the files and the VLC installation in a known, working state.
Loop, shuffle, and sequence trade-offs
Looping and shuffling solve different problems. Loop on Media Source repeats one file. Loop Playlist on VLC Video repeats the list as a whole. Shuffle Playlist changes the order in which list items play; it does not mean “repeat”. For a fixed sequence, playlist looping on and shuffle off is the direct choice.
Consider a local news loop assembled from separate clips. If the order is editorially meaningful, keep shuffle off and check that the list starts where expected. If the clips are independent music videos and a varied order is acceptable, shuffle may be useful, but it makes a particular next item less predictable. Decide whether the listener or viewer needs to know what comes next before selecting it.
A single long video has a different trade-off. It avoids playlist order management, but changing a segment generally means editing or replacing the video rather than moving an item in a list. A playlist is easier to rearrange, but each entry is another thing to verify. Neither arrangement guarantees that the broadcast will continue without interruption; source playback and delivery of the live stream are separate concerns.
For either source, prepare a short test that exercises the edge of playback. For Media Source, observe the end of the file and verify that it starts again. For VLC Video, let the last playlist item finish and see whether the first item follows, then check that the sequence is still ordered as intended. Also switch away from and back to the scene to confirm the selected visibility behaviour.
A blank frame between playlist items can be a separate practical concern from choosing Loop Playlist. If you are using this approach and see a gap at a transition, the specific checks in preventing a blank frame when OBS switches between playlist videos are more relevant than changing YouTube's go-live controls. Test the change in the programme output rather than assuming a property name describes the whole viewer experience.
VLC installation and architecture
The VLC Video source depends on VLC being installed. If it does not appear in OBS, check the installation before rebuilding the scene or changing the media files. OBS documents that 64-bit OBS requires 64-bit VLC. Matching the application architecture is part of making the source available, not a way to improve the stream itself.
This is an extra setup step compared with Media Source, which does not require VLC. For a machine that is already configured and used for other media work, installing VLC may be an acceptable trade-off for playlist handling. On a computer intended to run unattended, the extra dependency is another item to verify after installation or maintenance. Do not change versions immediately before an important broadcast without testing the source again.
OBS's VLC Video properties include a Network caching setting; the documentation lists 400 ms as its default. This is a configuration value, not evidence of a performance guarantee, and it does not establish that a particular network file or connection will play reliably. The decision here is mainly about local file organisation and playlist behaviour. Avoid treating a cache number as a substitute for testing your actual media and stream.
If you choose VLC Video, make a preflight list: confirm VLC is installed with the architecture matching OBS, open the source properties, verify all playlist entries, check Loop Playlist and Shuffle Playlist, and test the result through the intended scene. If you choose Media Source, the corresponding list is shorter: confirm the file, enable Loop, and test what happens on a scene switch. In either case, save the working scene configuration and keep a note of the expected playback behaviour.
Connect to YouTube and go live separately
OBS source playback and YouTube's live connection are different parts of the workflow. A source can repeat perfectly in an OBS preview while the encoder is not connected to YouTube. Likewise, connecting the encoder does not prove that the source has the right file, sound, or playback order. Keep those checks distinct so a source setting is not mistaken for a broadcast control.
For an encoder-based stream, YouTube's instructions are to configure the encoder with the server URL and stream key. For a scheduled event, use YouTube's Live Control Room workflow: check its preview and select Go live when ready. The YouTube encoder setup instructions describe the connection workflow. A source visibility property in OBS does not start or end the YouTube event, and changing a loop setting should not be treated as synchronising a scheduled public transition.
Before the event, check that the right scene is active, the source moves as expected, and its audio is audible at a sensible level. Then verify the Live Control Room preview and monitor the stream health. YouTube publishes encoder settings, bitrates, and resolution guidance; use the recommendations relevant to your resolution, frame rate, codec, and connection rather than assuming one setting suits every channel.
If your broadcast is intended to run overnight or around the clock, plan for the wider operating arrangement as well as the source. OBS depends on the computer and the connection staying available, and either can need attention. In the specific situation where a computer being switched off is the pain, StreamNeo turns an uploaded video into a YouTube live stream without keeping your computer running; it does not change the distinction between video playback and YouTube's own event workflow.
A final rehearsal should include the complete path: start the OBS output, confirm the YouTube preview, listen and watch for the actual stream, and check that the selected source repeats or advances as intended. YouTube recommends testing audio and motion and monitoring stream health. That is a reason to observe the real output, not a promise that either source type prevents interruptions. For background on how a long-running broadcast can affect its audience, see why 24/7 YouTube live streams can lose viewers after a few hours.

FAQ
Does Media Source need VLC installed?
No. Media Source is an OBS source that does not require VLC. VLC installation is required for the VLC Video source, which is the playlist-oriented option.
How do I loop one video in OBS?
Add the file as a Media Source and enable Loop in its properties. Check that the property is enabled in your installed OBS version, then let the file reach its end in a test to confirm it starts again.
How do I repeat a playlist without changing its order?
Use VLC Video, enable Loop Playlist, and leave Shuffle Playlist off. Confirm the playlist order and test a full pass, because loop repeats the list while shuffle changes its sequence.
Will either source start my YouTube live stream?
No. The source settings control playback inside OBS. Configure the encoder connection and follow YouTube's preview and go-live steps separately.
