A black interval between playlist videos does not, by itself, show where the problem starts. Compare OBS preview, a local recording and YouTube playback at the same transition before changing source or encoder settings.
If the OBS image also goes black, check the source type, playback-end behaviour and visibility. If OBS output and the recording look right but YouTube does not, investigate delivery separately; a source setting is not automatically the cause.
Determine where the black interval appears
Start with one transition you can observe, rather than changing several settings at once. Note which file is ending, which file should follow, and whether the gap is visible in OBS, the recording and YouTube. Even a brief interval can be difficult to diagnose from a viewer report alone, particularly if you did not see the transition yourself.
Watch the OBS preview as the first video ends. If possible, record locally in OBS and play back the same boundary. Then compare it with the Live Control Room preview or the delivered stream. These are separate points in the path: the source is composed in OBS, OBS produces an encoder output, and YouTube receives and presents that output. A black picture at the viewer's end does not prove that the original video source went black.
Use the comparison to choose a first investigation:
| What you observe | Where to start | What it does not establish |
|---|---|---|
| OBS preview and local recording both show black | Source playback, playlist handoff, scene and source visibility | Which setting or file caused it |
| OBS preview looks right but the local recording is black | Recording or output configuration, and whether you compared the same scene and moment | That YouTube is the cause |
| OBS and the local recording look right, but YouTube playback appears black | Encoder output, YouTube status and outbound connection checks | That the playlist is faulty |
| One viewer reports black while others do not | Confirm what other viewers and the Live Control Room show | That all viewers receive the same picture |
This is a way to narrow the problem, not a guarantee that every preview and playback discrepancy has a single explanation. YouTube's live-stream troubleshooting guidance advises checking the encoder and local archive, as well as encoder errors, CPU load and connectivity. If the issue is a disconnection rather than a picture gap, the checks in YouTube stream RTMP fixes for a VPS in India address a different symptom and should not be treated as proof that the two problems share a cause.
Write down what each view shows before you make a change. Then test the same boundary again after changing one relevant setting. If you change the source type, loop behaviour and scene visibility together, you may remove the symptom without learning which condition mattered, or leave yourself with a new setting that is hard to assess.
Watch OBS preview at the transition
Keep OBS visible and watch the preview through the last moments of one video and the start of the next. Check whether the preview goes completely black, whether it shows another scene, or whether the picture remains while only the audio changes. Those details help distinguish an empty-looking scene from a video playback issue. A still image, a hidden media source or a scene transition can look like a failed playlist to someone watching the stream.
Repeat the observation with a short local recording if you can. Do not rely only on the preview: the preview is a useful first comparison, while the recording provides a record of what OBS produced. Make sure you examine the same transition and not a different playback cycle. If the source order changes or the playlist starts from a different item, the comparison will not tell you much about the original interval.
If the preview and recording both show the gap, focus first on what OBS is asked to play and what remains visible at the end of playback. If both appear continuous, take the encoder and delivery path seriously instead of assuming the playlist needs a different setting. YouTube recommends inspecting the stream in the encoder and local archive, reviewing dashboard errors and CPU load, and testing outbound internet connectivity when encoder output looks healthy. Do not interpret this as a promise that a particular check will identify every cause.
For a channel built from local video files, keep a small test scene or a copy of the scene collection if practical. That lets you try a source or visibility change without disrupting the scene you depend on. It also helps keep the troubleshooting question narrow: did this source behaviour change the black interval at the boundary, or did it only change something else about the scene?
Check source type and playback-end behaviour
In OBS, identify what source is actually playing the video. A single Media Source and a VLC Video source serve different needs. Media Source is suitable for one local audio or video file; VLC Video is the documented choice for a playlist of multiple local files. If the source is a browser, capture device or scene rather than either of these, do not apply playlist instructions to it without first checking how that source works.
OBS's Media Sources guide documents Media Source options including Loop and “Show nothing when playback ends”. The latter hides the source after the file finishes. That setting can explain why a single file disappears when it ends, but OBS does not document it as a universal fix for a gap between items in every playlist. Check what your particular source is configured to do; do not infer a cause from the label alone.
For a multi-file list, check that the intended files are present and ordered correctly, and that the source is VLC Video. A file that is missing, moved, unreadable or simply not in the list cannot be expected to play as the next item. The source's loop and visibility behaviour also matter to a continuously running scene. The setting that controls what happens while a source is hidden may stop, pause or restart playback, depending on its selection. If scenes switch during your broadcast, that behaviour can affect what happens when the source becomes visible again.
A useful test is to reproduce the boundary with the same files and scene arrangement used on air. First test without changing the source. Then change the setting that matches the observed behaviour and test again. For example, if one file is meant to repeat, check its own loop setting; if the source vanishes after finishing, inspect playback-end behaviour. If you have a playlist, examine playlist entries and the source's visibility settings instead of treating a single-file loop option as playlist control.
If you are setting up a channel from videos rather than building a live camera production, creating a 24/7 Hindi ghazal channel from video files covers the broader file-based workflow. It does not replace checking the exact OBS source and boundary in your own scene.
Verify the source or scene is visible
A video can be present in a scene and still not be the visible thing OBS is showing. Look at the Sources list and the scene selected at the time of the black interval. Check whether the relevant source is enabled, whether another source is layered above it, and whether OBS has switched to another scene. The OBS sources guide explains source visibility and ordering; inspect the actual scene rather than assuming the playlist is the only image-producing element.
When a source is hidden and then shown, its visibility behaviour can determine whether playback continues, pauses or starts over. That is distinct from whether the file itself loops at its end. A scene transition can also make a momentary dark image appear even when the file is playable. Keep the test simple: observe the selected scene, the visibility state and the media's playback position together.
For a devotional reading, local news loop or study channel, a background image or text overlay may make a black interval less obvious, but it does not repair the underlying handoff. First establish whether the video source is actually absent or whether the scene composition changes. A visual cover can conceal a symptom from viewers while leaving playback or audio behaviour unchanged.
If you are troubleshooting a long-running channel from a remote machine, the practical choice is between continuing to operate OBS yourself and delegating the repeated file playback. StreamNeo can remove the need to leave your own computer running for an uploaded-video YouTube stream, which addresses that specific operational burden; it does not diagnose an OBS playlist or establish that a black interval has been fixed.
Use Media Source loop for one repeating clip
If the plan is to repeat one local file, use OBS Media Source and check its Loop option. This is the fitting source-level control for replaying a single clip. Confirm that the selected file is the intended one and that playback reaches its end in your test. Do not add unrelated files to a single-file source and expect the Loop option to serve as playlist sequencing.
Also inspect “Show nothing when playback ends”. OBS documents that option as hiding the source when playback ends. If the file is meant to repeat, examine how that end-of-playback behaviour interacts with the Loop setting and verify it in preview and recording. Do not assume that toggling this one option will fix every black interval: the documented behaviour concerns the source after playback ends, not a guarantee of gapless handoff between multiple clips.
A simple verification is to start the file near its end in a test scene, then observe whether it restarts, disappears or leaves another scene visible. If the result differs from what you intended, adjust the relevant option and test the same boundary again. Keep other scene sources and transitions stable while testing so that the result is attributable to a small change.
For a channel based on a single ambience track or a repeated prayer video, decide whether the file itself contains the full duration and ending you expect. A black frame encoded into the file is different from OBS hiding a source after playback. Scrubbing the file locally can reveal whether the black picture is already in the media. If it is, changing the OBS loop setting will repeat that content rather than remove it.
Use VLC Video for multiple local files
For several local videos that should play as a sequence, use OBS's VLC Video source and check the playlist entries and order. OBS documents VLC Video as the source for playlists. Confirm that the files exist at the paths recorded in the list and that the sequence in the source matches the sequence you intend. Moving a file after creating the playlist can leave the source pointing at a path that is no longer valid.
Check Loop Playlist if the sequence should repeat after its final item. A playlist that should stop and one that should repeat are different jobs, so choose based on the channel's schedule rather than enabling a loop reflexively. Test both an ordinary item-to-item boundary and the final-to-first boundary if repeating the whole list. A setting that behaves as expected at one point in the list does not prove that every entry or the last handoff works.
Inspect the VLC source's visibility behaviour too. OBS documents choices that affect playback while the source is hidden, including continuing, pausing or stopping and restarting when visible. Consider whether the source is ever hidden by a scene change, even briefly. When using more than one scene, test with the actual scene sequence that will be live rather than a simplified scene that keeps the source visible all the time.
Do not promise yourself a gapless transition merely because VLC Video accepts a playlist. The documented source choice and loop controls tell you how to configure playback; they do not promise that every combination of file, decode, machine and scene will have no interval. Test the actual files and watch the transition in OBS, a local recording and YouTube before relying on it overnight. If you need help distinguishing the OBS feed from what viewers receive, checking whether a looped ambience stream is still live on YouTube is relevant to the delivery side, not a substitute for source diagnosis.
Confirm VLC is installed with matching architecture
VLC Video depends on VLC being installed. If the VLC Video source is missing, unavailable or does not load as expected, check the installation before rebuilding the playlist. OBS's documentation specifies that a 64-bit OBS installation requires 64-bit VLC. Check whether the OBS application you run is 64-bit, then install the corresponding VLC version from the vendor's official source if necessary. This is a compatibility prerequisite, not evidence that a mismatched installation caused the original black interval.
After installation, reopen OBS if needed and confirm that VLC Video is available as a source. Add a small test playlist with known local files and verify playback before swapping it into a production scene. If playback remains problematic, check file paths, playlist contents, source visibility and the transition itself. Separate a source that cannot load at all from one that plays but goes black at a boundary; they call for different checks.
If VLC is already installed with matching architecture and the playlist works in a test scene, avoid reinstalling it as a general troubleshooting ritual. Return to the evidence you collected from the preview and local archive. If those are clean, the next useful checks are on the encoder and YouTube delivery path rather than repeated changes to the playlist.
Test the whole path before returning to live
Once a change appears helpful, test the complete path that viewers will use. YouTube's guidance on testing a live stream recommends checking the Live Control Room preview before starting and testing a live stream. Run a test that includes a real item-to-item boundary, and, if the playlist repeats, the final-to-first transition too. Watch OBS preview and the local recording as well as YouTube playback.
When OBS and the recording are healthy but YouTube is not, review encoder status and the Live Control Room for errors. Check CPU load and, if encoder output appears healthy, test the outbound connection. If only one viewer reports a problem, ask whether others on different connections see the same thing; a single report may be local playback or network trouble, while multiple independent reports warrant closer inspection of the encoder path. Treat these as diagnostic cues, not a definitive classification.
Change one thing at a time and record what you tested. For an overnight devotional stream, for example, note the source type, loop choice, visibility behaviour and the exact boundary that passed in a test. This makes it easier to repeat the check after a file or scene is changed. A successful test reduces uncertainty about that setup; it cannot guarantee that a future broadcast will have no interruption.

FAQ
Why does OBS go black between playlist videos?
The symptom can come from source playback, a file or playlist handoff, playback-end behaviour, source visibility or a scene change. First compare OBS preview and a local recording at the same boundary; the symptom alone does not confirm which cause applies.
Should I use Media Source or VLC Video?
Use Media Source when one local file should play, including when that file should repeat using Loop. For multiple local files in a sequence, OBS documents VLC Video as the playlist-capable source; VLC must be installed, with matching architecture for your OBS installation.
OBS looks fine, but YouTube viewers see black. What should I check?
Compare the local recording and YouTube playback, then inspect encoder output, Live Control Room errors, CPU load and outbound connectivity. Ask whether more than one viewer sees the same issue, but do not conclude from one report that the playlist or YouTube is definitely at fault.
Does enabling Loop Playlist guarantee gapless playback?
No. Loop Playlist is a playback setting, not a promise that every file and setup transitions without a gap. Test the actual playlist boundary in OBS, a local recording and YouTube before relying on it.
