A video file reaching its last frame does not have to end your YouTube livestream. In OBS, enable Loop on a Media Source for one file, or Loop Playlist on a VLC Video source for a sequence, then keep that source active in the scene you are sending.
The important distinction is that YouTube receives the encoder’s outgoing feed, not the local file itself. If the encoder keeps sending a valid scene, a file ending is a playback transition; if the encoder stops sending content, YouTube’s guidance is that the stream ends. Set up the repeat behaviour and test it before relying on it overnight.
Why a file ending need not end the stream
A video file is one input to your broadcast. OBS plays that input inside a scene, combines it with any other visible or audible sources, and sends the resulting feed to YouTube while streaming is active. Reaching the end of a finite file changes what that source plays; it does not, by itself, tell the encoder to stop sending the scene.
That distinction explains why two apparently similar failures have different causes. If the file reaches its end and the picture freezes, goes black, or disappears while OBS still streams, investigate the source’s playback settings and scene composition. If OBS stops streaming or YouTube reports that it is no longer receiving encoder content, investigate the encoder connection and stream state instead. A loop setting addresses the first problem, not a dropped or stopped outgoing feed.
YouTube’s encoder instructions say to stop sending content from the encoder to end the stream. That wording is useful when diagnosing the file-end question: the local file’s duration and the broadcast’s duration are not necessarily the same. Still, you should not assume the stream continues just because OBS is open. The scene must remain active and the encoder must continue sending content.
For a single devotional recording, for example, you might put the video and its audio in one Media Source, enable its loop option, and send that scene for the planned broadcast. For a station made from several ambience clips, a playlist source may be more convenient. The destination and encoder workflow are otherwise the same.
If you are also choosing between a home computer and a hosted arrangement for long-running playback, compare the operational trade-offs in this guide to cloud services for looping videos on YouTube 24/7. The immediate file-end fix, however, is a source setting in OBS, followed by a check that the complete scene is still being transmitted.
Loop one file with OBS Media Source
Use a Media Source when one local video should repeat from its end back to its beginning. In OBS, open the scene intended for the livestream, add a Media Source, and select the video file. If you already have that source in the scene, open its properties instead of adding a duplicate. Turn on Loop in the source properties and confirm the change.
OBS’s Media Sources documentation describes the loop option as repeating a file after playback completes. It applies to the media source’s playback, not to YouTube’s stream controls. You do not need to restart the broadcast every time the file reaches its end; the source is meant to begin playback again while the scene remains in use.
Check the other source properties while you are there. Confirm that the intended file is selected, that the source is enabled, and that its audio is available in the OBS mixer if the recording includes sound. If a file has separate audio elsewhere in the scene, establish which source should carry it so the repeat does not create doubled sound. The correct arrangement depends on how the recording was prepared.
When you add a source, OBS may offer to create a new one or reuse an existing one. Reusing can be appropriate if it is the same file and the same intended behaviour, but changing a source that another scene depends on can alter that scene too. If you need different playback settings or files for different broadcasts, give them separate sources and check which one is active in the live scene.
A single-file loop is the least complicated arrangement when there is one complete programme, such as a long music recording or a fixed news loop. It also repeats the same ending and opening every time. If there is an audible click, an abrupt cut, or a visible flash at that join, Loop is functioning but the media itself may not have a seamless boundary. See the practical discussion of black frames and audio pops at a loop seam when the source restarts but the transition is distracting.
Loop a playlist with OBS VLC Video
For a sequence of separate clips, use OBS’s VLC Video source rather than creating a stack of Media Sources and trying to manage their order manually. Add a VLC Video source to the scene, add the desired files to its playlist, arrange their order, and enable Loop Playlist. The playlist source is intended to play through its entries and repeat the playlist when it reaches the end.
OBS notes that VLC must be installed for the VLC Video source to appear. If you cannot find it in the source list, check that prerequisite and reopen OBS if needed. Interface labels can vary between versions, so look for the VLC Video source and its playlist properties rather than assuming that a missing item means OBS cannot repeat clips at all. For one clip, the Media Source’s Loop setting remains the simpler route.
Decide the playlist order before going live. A sequence of short clips can make a channel feel varied, but the transition between files may include a pause, a brief black frame, or an abrupt audio change. Listen to the change from the end of one clip into the beginning of the next. Also verify that each item has the right dimensions and audio level; a playlist only automates playback order, it does not make clips match one another.
| Need | OBS source | Setting to check | What repeats |
|---|---|---|---|
| One recording throughout the broadcast | Media Source | Loop | The selected file after it completes |
| Several recordings in sequence | VLC Video | Loop Playlist | The playlist after its final item |
These choices do not change what YouTube receives. In both cases, OBS sends the composed scene while its stream is active. The difference is whether the source repeats one file or cycles a list of files. If you need scheduled changes to different playlists rather than one repeating sequence, that is a separate workflow; the guide to different playlists on a scheduled livestream covers that broader arrangement.
Keep the looping source active in the scene
A loop option cannot help if the source is not part of the scene being sent. Confirm that the Media Source or VLC Video source is visible and enabled in the intended scene, not merely present in another scene or hidden under an opaque layer. In OBS, a source can exist in the Sources list yet be hidden, disabled, or covered by another full-frame source.
Check the scene selected for streaming. If you use scene switching, transitions, or a separate standby scene, make sure the live scene actually contains the looping source at the point when the file is expected to repeat. A common configuration mistake is to test a scene with the file, then start the stream with a different scene selected. The preview in OBS should show the content you expect YouTube to receive.
Keep the file available at the path the source expects. Moving, renaming, or disconnecting a file after configuring a source can leave OBS unable to play it. Before a long broadcast, reopen the source properties and confirm the selected media path. If the file is on removable storage, make sure that storage stays connected and does not enter a state that makes the file unavailable.
Also check the audio path. The picture can repeat correctly while the audio is muted, routed from the wrong source, or unexpectedly duplicated. Watch the OBS audio mixer while the clip plays and listen to the actual stream during a test. A meter moving is helpful, but it does not prove that the audio sounds right at the viewer’s end.
If you plan to run a channel from a phone, remember that the phone may be useful for checking or managing a broadcast but is not a substitute for a configured, active playback source. The guide to managing a 24/7 channel from a phone separates tasks you can reasonably handle remotely from work that needs attention to the streaming setup itself.
Test the transition at the file’s end
Do not infer that looping works from the checkbox alone. Start a private or unlisted test broadcast and let the file reach its actual end. A short test that stops before the transition can confirm that the opening plays, but it cannot confirm that the source restarts or that the scene remains useful through the change.
Watch OBS as the media finishes. The picture should return to the beginning for a Media Source with Loop enabled. With VLC Video, the next playlist entry should play, and the first entry should follow when the playlist completes if Loop Playlist is enabled. Keep watching the encoder’s status as well: the relevant result is that the outgoing feed continues, not simply that the local preview looks correct.
Listen across the boundary, preferably on a device or playback path other than the one producing the stream. Check for a gap, a sudden volume change, a click, or duplicated audio. If the visual cut is noticeable, inspect the end and beginning of the file. Some recordings have a clean restart; others contain a fade to black or a pause that becomes obvious when repeated. A source loop repeats what is in the file, including its ending.
YouTube recommends testing the setup and checking the Live Control Room preview and stream audio and video. Its live streaming checklist is a useful companion to the OBS-side test. Check that the preview shows the intended scene and that sound is present before you depend on the arrangement for viewers.
Test the same scene, source, and audio configuration you plan to use. If you swap files, change scenes, or adjust source visibility after testing, repeat the relevant part of the test. A test of a different scene only establishes that the different scene worked.
Check the encoder feed in YouTube
OBS preview and YouTube’s viewer-facing preview answer different questions. The OBS canvas shows what the scene looks like locally. The Live Control Room lets you check what YouTube is receiving and how the stream appears at the platform. Use both: confirm the loop in OBS, then confirm the broadcast preview and audio on YouTube.
If the local video restarts but YouTube’s preview freezes or loses the feed, do not keep changing the loop checkbox as the first response. Check whether OBS still says it is streaming and whether it is sending content. Then check the connection and the Live Control Room status. The file-end behaviour can be correct even when a separate encoder or network issue interrupts delivery.
If YouTube shows a continuing feed but the picture is black, return to the scene and source checks: visibility, ordering, selected scene, and file availability. If the picture is present but silent, inspect the audio routing and mixer. Isolating the visible symptom helps you distinguish a source problem from a transmission problem.
For an intentional finish, follow YouTube’s encoder guidance: once you mean to end the live broadcast, stop sending content from the encoder. Do not confuse that planned stop with a finite media file reaching its last frame. YouTube also says streams under 12 hours are automatically archived; do not assume the same archive behaviour for a stream longer than that based on this guidance. If the replay matters, check YouTube’s current official information and your own Live Control Room after the broadcast.
Troubleshoot a source that stops or goes blank
When the source does not repeat, work through the path from the media file to YouTube rather than changing several settings at once. First identify whether OBS’s local source playback stopped, the source is hidden, the scene changed, or the entire encoder feed stopped. Each points to a different cause.
- The file ends and the source stays blank: Reopen the Media Source properties and confirm Loop is on. For a playlist, confirm the clips are in the VLC Video playlist and Loop Playlist is enabled. Let playback run through the end again to verify the change.
- The source is missing in the scene: Check whether it is enabled and visible, whether another layer covers it, and whether the selected scene is the one you intended to stream. Verify that the media file remains at the configured location.
- The playlist source is unavailable: Confirm VLC is installed, since OBS requires it for VLC Video. If you only need a single file, use Media Source instead of troubleshooting a playlist you do not need.
- The picture repeats but the sound does not: Check the source’s audio and OBS mixer, then listen to a YouTube test. Look for a muted track, an unintended audio source, or an abrupt boundary in the recording.
- OBS preview works but YouTube does not: Check the encoder’s streaming state and YouTube’s Live Control Room. A successful local preview does not establish that the outgoing feed is still reaching the platform.
Make one change at a time and repeat the end-of-file test. That keeps the cause visible: if you toggle looping, change the file path, and rebuild the scene together, a later success will not tell you which change mattered. Record the working scene and source arrangement in a note if you will need to restore it after an update or a change of operator.
A source that stops can also expose a broader operational choice. Running OBS locally means the computer and playback setup must stay available for the broadcast; a cloud-run file workflow can remove the need to leave your own computer switched on. StreamNeo removes that specific burden when your file and YouTube channel are ready by running the uploaded video as a 24/7 broadcast without keeping your computer on. It is for YouTube, so first decide whether a repeating file or playlist in OBS is the setup you actually need.

FAQ
Will YouTube keep my stream live when the video file ends?
It can continue receiving a stream if the encoder keeps sending content; the end of one local file alone does not end the broadcast. Configure the source to loop and check that OBS continues sending the scene. If the encoder stops sending content, do not expect the stream to continue on the strength of the local file setting.
Where is the loop setting in OBS?
For one file, open the Media Source properties and enable Loop. For several files, use VLC Video, add them to its playlist, and enable Loop Playlist. VLC must be installed for the VLC Video source to appear.
Should I use Media Source or VLC Video?
Use Media Source when one file should repeat. Use VLC Video when you want several files to play in sequence and the playlist to repeat. Test the transition and audio in the scene you intend to broadcast.
How do I know the loop works for viewers?
Run a private or unlisted test long enough to reach the file’s end, then watch OBS and YouTube’s Live Control Room. Confirm the picture restarts or the playlist advances, the audio remains right, and the encoder feed continues reaching YouTube.
