If you want background music to continue while OBS changes playlist videos, add it as a separate looping Media Source and keep that source active in the scene. If you mean each video’s own soundtrack should flow seamlessly into the next, OBS’s documentation does not promise gapless VLC playlist transitions; you will need to test your specific files and consider preparing a continuous audio track.
These are different jobs. A separate music bed can continue independently of video-item changes, while clip-native audio changes with each item and may have a boundary between them. The steps below help you choose the right behaviour, configure it, and check the result before using it live.
Decide which audio should continue
First decide whether the continuous sound is a background layer or the sound attached to each video. For a devotional channel, you might want one tanpura or instrumental bed to continue while the screen moves between visual loops. For a lecture playlist, you may instead need the speech and room sound embedded in each recording to carry through every transition.
A separate looping audio source addresses the first goal. It plays its own file independently of the VLC playlist’s video items, so changing the video does not by itself require changing the music source. That is a practical configuration based on OBS’s separate source controls, not a guarantee that the combined scene will be free of every pause, overlap, or file-specific issue.
The second goal is harder. VLC Video can play a playlist, but the OBS guide does not describe its transitions as sample-continuous or gapless. A playlist control such as Loop or Shuffle governs playlist behaviour; it is not documented as a way to remove audio gaps at item boundaries. If continuous clip-native sound is essential, consider editing the source material into one continuous asset, then record and listen to the result before streaming.
Make the choice before adjusting mixer faders. If your goal is a music bed, decide whether the clips’ own audio should be muted or mixed underneath it. If the soundtrack must come from each clip, do not add a music bed merely to mask transitions: it can obscure speech and still cannot make clip-native audio seamless. For a broader channel decision about whether to broadcast a continuous programme or rely on uploaded videos, see the comparison of YouTube Live and playlists for an always-on radio station.
Add a separate looping Media Source
In the scene that carries the video playlist, add a Media Source for the audio file you want to repeat. In its properties, select the file and enable Loop. OBS describes Loop as repeating the file after playback completes. The official OBS Media Sources guide lists formats including MP3, AAC, OGG and WAV; use a supported file and check that it plays correctly in a short recording.
Keep the audio source distinct from the VLC Video source. The VLC source is responsible for the playlist of visual items, while the Media Source handles the music file. This makes it easier to set the audio bed’s level, mute it temporarily, or replace it without rebuilding the video playlist.
Add or retain the VLC Video source for the videos. OBS’s guide says VLC Video supports a playlist, with controls that include loop, shuffle, visibility behaviour, caching and audio tracks. VLC must be installed for this source to appear; match VLC’s architecture to OBS, such as installing 64-bit VLC for 64-bit OBS. The guide does not say that playlist loop or shuffle creates gapless audio transitions.
If you are setting up a long-running playlist rather than a one-off scene, keep the scene structure simple and name sources clearly, for example “Video playlist” and “Background music”. This reduces the chance of muting or hiding the wrong source during a later change. For a playlist that needs to select sermons in random order, the folder-based FFmpeg sermon setup covers a different workflow; it is not a fix for OBS boundary gaps.
Keep the audio source active in the scene
A source can be present in a scene without being audible at every moment. Check that the Media Source is enabled and that its visibility behaviour is suitable for how you switch scenes. If you use one scene for the entire playlist, leave the source in that scene rather than removing and re-adding it at each video change.
This matters because the goal is to keep the music source independent of playlist items. If you switch to another scene that does not contain the audio source, the bed may stop being part of the programme. If you use several scenes, add the audio source to each relevant one, or use a suitable shared-source arrangement and verify how your scene changes behave in your OBS version.
Do not assume a source will keep playing merely because its name remains visible in the Sources panel. Check its eye/visibility state and the source properties, then watch the audio meter while playback runs. If the meter falls when the scene changes, investigate the scene arrangement before adjusting the YouTube encoder or playlist.
A Media Source’s own Loop setting controls repeating that file when it reaches its end. It does not preserve the soundtrack embedded in the VLC playlist’s current and next videos. Treat the music bed and playlist audio as independent layers, and test the transitions that matter to your channel rather than relying on a checkbox to cover both cases.
Mute playlist audio if needed
Each playlist video may contain its own audio. If you want only the separate music bed, find the VLC Video source in the OBS Audio Mixer and mute it. Then confirm the Media Source remains unmuted and its meter responds. This avoids hearing the video’s embedded sound underneath the continuous bed.
If you want both layers, leave the VLC source unmuted and balance the two sources deliberately. For example, a quiet instrumental bed under spoken announcements may be appropriate, while two full-volume music tracks can sound cluttered. Listen on the same kind of headphones or speakers your viewers are likely to use, but do not rely on meter readings alone: a signal can register while still sounding too loud, too quiet, or masked.
Check whether each clip begins or ends with silence. Muting VLC may conceal an awkward transition, but it also removes any useful announcement or music embedded in those clips. Conversely, leaving it audible does not make a transition seamless. Decide source by source what should be heard, and do not use the mixer to compensate for missing or badly edited audio at a boundary.
For a channel whose main content is music, there is a separate planning question about whether a continuous radio-style broadcast fits the material. The Marathi music radio livestream guide is useful for that broader format decision; the OBS setup here concerns how the sources behave together, not what content you should broadcast.
Check mixer routing and levels
OBS routes source audio through the mixer, where you can monitor and change levels. Before a test, confirm that the intended source is not muted, that its meter moves during playback, and that the programme output includes it. If you have monitoring enabled, verify that monitoring does not create an unintended doubled signal in your headphones. Keep the test simple: one playlist source, one audio bed, and the output you expect to use.
Start with conservative levels and listen to a recording. A meter helps identify silence or an unexpectedly active source, but it does not tell you whether the mix is comfortable. Speech can be hard to understand beneath a music bed even when neither source appears to be clipping. If speech is important, set the bed low enough that words remain clear and test at normal listening volume.
A useful check is to record a short sample with the video playlist changing at least once. Listen to the entire sample, not just the loudest moment. Note whether music continues, whether the video soundtrack leaks through, and whether either source drops out at the scene or item change. If you need a more detailed approach to balancing spoken material, the guide to consistent podcast audio levels on YouTube Live explains the listening and level checks that also apply here.
Do not change several controls at once. If the music disappears, first check whether the source is active and unmuted, then whether the scene contains it, and then whether its file has reached the end with Loop disabled. If only the video audio disappears, check the VLC mixer state and the clip itself. Changing levels cannot correct a source that is absent from the active scene.
Test several playlist boundaries
A single successful hand-off is not enough to establish how your playlist behaves. Record a short test that includes several different item changes: for instance, a clip with sound followed by one with silence, and a clip whose audio begins or ends abruptly. Listen for gaps, overlaps, unexpected soundtrack changes and any music bed that stops or restarts.
The reason to test is straightforward: OBS documents playlist and source controls, but it does not promise gapless audio between VLC playlist items. The actual material matters too. A pause could be present in the source file itself; a sudden change in loudness can come from the clips rather than OBS. Make a note of the item and timestamp so you can distinguish a playlist boundary from silence within a file.
For background music, focus on whether the separate Media Source continues through the changes and whether its own file loops as expected. Check that the ending of the audio file does not contain unwanted silence before it repeats. For clip-native audio, listen specifically at every change. If one transition matters more than others, test that pair repeatedly in a local recording; do not infer that an OBS setting guarantees the same result for every pair.
If clip-native sound must flow as one continuous performance, a practical alternative is to prepare a single continuous audio track or join/edit the relevant media in a suitable editor. This is a workflow choice, not an OBS-specific guarantee: inspect the finished asset and test it in the scene. A community Media Playlist Source resource offers playlist-management features, but its listing does not establish that it removes audio cutouts. Treat it as an alternative way to manage a playlist, not a gapless-audio fix.
Choose the workflow that fits the channel
Use the comparison below to keep the decision tied to the sound you need. The key difference is whether the sound should be independent of the videos or should follow the individual clips.
| Need | Practical setup | What to verify |
|---|---|---|
| Continuous background music across changing video | Separate looping Media Source alongside VLC Video | Music stays audible through item changes; video audio is muted or mixed as intended |
| Each clip’s own soundtrack, with no requirement for seamless joins | VLC Video playlist with its audio enabled | Each clip is audible; the boundary sounds acceptable in a recording |
| Clip-native soundtrack must behave as a continuous performance | Edit or prepare a continuous audio asset where suitable | The finished file has acceptable joins and plays correctly in the intended scene |
| Easier playlist item management is the main need | Consider a playlist-management alternative such as the community resource | Required features and platform support; do not assume it fixes gaps |
The community plugin listing identifies OBS 30.0.0 as its minimum version and lists Windows, macOS and Linux support; it also says audio-track and subtitle selection are not supported. Check the current listing and compatibility details before installing it. Those are plugin details, not a claim about gapless playback, and the basic separate-source setup does not require that plugin.
If you are deciding between keeping a local OBS computer on overnight and using a different broadcast workflow, consider what needs to run continuously and what you can monitor. The comparison of FFmpeg and cloud service workflows for a 24/7 podcast stream discusses that broader operational choice. StreamNeo can remove the specific burden of keeping your own computer running for an uploaded-file YouTube stream, but it does not replace this OBS scene-and-mixer test when OBS is your chosen workflow.

FAQ
Does a looping Media Source keep every playlist video’s soundtrack continuous?
No. It loops its own audio file; it does not carry the sound embedded in one VLC playlist video into the next. If clip-native audio is the requirement, record and inspect the boundaries, or prepare a continuous audio asset where appropriate.
Should I mute VLC Video when I add a separate music file?
Mute it if you want to hear only the separate music bed and none of the videos’ embedded audio. If both should be audible, leave it unmuted and balance the sources by listening to a recording, especially when clips include speech.
Do VLC playlist Loop or Shuffle settings remove transition gaps?
OBS documents those as playlist controls, not as gapless-audio features. They can change how items repeat or are selected, but you should not treat them as a promise that audio will have no pause or overlap at an item boundary.
What should I test before using this live?
Record several playlist changes in the scene you intend to use. Check that the music bed remains active, that the VLC audio is muted or mixed as intended, and that clip starts and endings do not contain unwanted silence or abrupt level changes.
