Changing the video in an OBS-based YouTube live loop does not, by itself, require ending the YouTube event. Keep OBS sending its output and change the media source or active scene; do not click End Stream merely to replace a file.
That is the documented division of roles, not a promise of a gap-free handover. Prepare the replacement and rehearse the exact change first: a source may need time to load, and the official guides do not guarantee how every file and computer will behave during a transition.
The YouTube event and encoder output are separate
Think of the broadcast as two connected parts. YouTube Live Control Room holds the live event, while OBS is the encoder that sends the audio and video feed to it. The media in OBS determines what appears in that feed; YouTube does not choose which local video file OBS is playing.
YouTube’s encoder instructions distinguish connecting and starting the encoder from ending the broadcast. They say to click End Stream and stop sending content from the encoder to end the stream. Changing a file in OBS is a different operation: it changes the content being sent, provided the encoder output remains active.
This distinction is useful when planning a change. A live event can remain open while OBS changes the scene or source. Conversely, stopping OBS’s output or ending the event is not a necessary part of selecting another video. The exact controls differ in other encoder software, so the steps here focus on OBS rather than assuming every encoder behaves identically.
A YouTube channel playlist is also different from the playlist discussed here. In this article, a playlist is a set of local media files loaded into an OBS source. YouTube receives the encoder feed; it does not automatically substitute another local file when you change a YouTube playlist.
Pick a source that matches the job
For a single video that should replay, use an OBS Media Source. Add the source to the scene, choose the local file, and enable Loop if playback should start again when it finishes. OBS lists formats including MP4, TS, MOV, FLV, MKV, AVI, GIF and WebM. A familiar extension alone does not prove that a particular file will play correctly, so test the actual file in your scene.
For a sequence of files, use VLC Video, which creates a playlist source. VLC must be installed for this source type to appear, and OBS notes that 64-bit OBS requires 64-bit VLC. The source has Loop Playlist, enabled by default, and Shuffle Playlist, disabled by default. Keep shuffle off when the order matters, such as a news loop with a fixed sequence or a devotional set arranged by time of day.
| What you need | OBS source | Useful control | Check before relying on it |
|---|---|---|---|
| Repeat one local file | Media Source | Loop | Confirm the file and its audio play as expected |
| Play several files in sequence | VLC Video | Playlist and Loop Playlist | Confirm file order and that VLC is installed |
| Vary the order of several files | VLC Video | Shuffle Playlist | Decide whether an unpredictable order suits the channel |
| Prepare a visible change before it goes live | Scene with the replacement source | Studio Mode preview and transition | Rehearse what viewers see when the change is made |
The OBS Media Sources guide describes these source types and controls. Use a Media Source when one file is the unit you want to replace or repeat. Use VLC Video when you need OBS to play a list. Neither choice establishes that a transition will be seamless on your setup.
If you are comparing workflows, a text-file playlist with FFmpeg is a separate approach, not an OBS source setting. An M3U8 file for live streaming is another playlist format with its own use cases. Those guides can help you assess alternatives, but the steps below concern a source change in OBS.
Prepare and test the replacement content
Do the preparation before the broadcast, not while trying to repair a live transition. Put the new file somewhere OBS can access, add it to a source or scene, and check that it opens. Confirm its picture, audio, orientation and duration suit the loop. If several files are involved, inspect the entire list and make sure the order is intentional.
Keep the current scene or source intact until the replacement is ready. If you edit the only live source and select a bad path or incompatible file, you may have no prepared fallback to show. A safer arrangement is to make a second scene for the replacement, or keep a backup source in the existing scene, then test both before switching.
Check any source behaviour that affects reloading. OBS documents that a Media Source set to Close file when inactive can take a short time to reload when it becomes active again. If you switch away and back, or activate a scene containing that source, the reload may leave a temporary blank or frozen-looking moment. Whether this setting is useful depends on your setup; inspect it and rehearse the same activation you plan to use on air.
Audio deserves a separate check. A replacement might have a different soundtrack, a lower level, or no audio at all. Listen while it plays, and confirm that the intended audio source remains active if the video itself should be silent. A picture that appears in preview is not enough evidence that the complete programme is ready.
Use a private or otherwise non-public test where practical, or test the source and transition in OBS before going live. OBS’s Quick Start Guide recommends testing settings before streaming. It does not promise a particular transition result; treat a successful rehearsal as evidence about the files and configuration you tested, not a guarantee for all future changes.
Set up a deliberate scene or source switch
There are two common ways to prepare a manual change. You can add a replacement Media Source to the current scene and change which source is visible, or build a separate scene containing the replacement and switch to that scene. Separate scenes make it easier to label what is currently live and what is next. A scene named “Next loop” is less ambiguous than several similarly named media sources.
OBS describes scenes as layouts and sources as the media or devices included in those layouts. In Studio Mode, you can prepare a scene in preview before sending it to the live output. The OBS overview guide explains scenes, sources and Studio Mode. Preview can help you inspect the intended scene, but it cannot prove that the transition will be gap-free once it reaches viewers.
Before a manual switch, check which scene is on the programme output and which one is only in preview. Select the intended replacement and inspect its picture and audio. Then use the transition control to take it live. If you are not using Studio Mode, selecting a scene may change the output immediately, so know which control you are about to use.
For a playlist source, changing the list is different from changing scenes. Make sure the replacement files are loaded in the source and that loop and shuffle settings match the schedule. If you want a manually chosen next video, a playlist that advances automatically may not be the clearest arrangement; a pair of prepared scenes can give you more explicit control.
Keep the output running; avoid End Stream
Once the change is ready, leave OBS’s stream output active and keep the YouTube event open. Make the content change in OBS: activate the prepared scene, show the replacement source, or update the playlist as appropriate. Do not click End Stream in YouTube Studio just because you want the audience to see a different file.
The basic sequence is straightforward: connect OBS to the event, confirm the preview, and start the broadcast according to YouTube’s workflow. After the event is live, leave the output running while you make the planned content switch. Ending the event is for finishing the broadcast, not for choosing the next video.
Do not confuse a scene change with an encoder interruption. A scene change changes what OBS composes into its output. Stopping the output, disconnecting the encoder, or ending the event are different actions and can interrupt the feed. If a source change appears to fail, avoid repeatedly pressing unrelated stop and start controls; first determine whether OBS is still streaming and whether the new source is actually active.
For a local workstation, that distinction also matters overnight. If a person is at the controls, they can inspect the transition and correct a wrong selection. For a channel meant to run unattended, changing files is only one part of the operating plan: the computer, OBS, connection and media all need attention. If the fragile part is keeping a computer running through the night, a workflow that lets you upload a file and leave your own computer off can remove that specific task; StreamNeo turns an uploaded video into a YouTube live stream, but you still need to prepare and check the content.
Some channels have different needs. If you require hands-on scene composition, overlays, cameras or other live inputs, OBS gives you controls for those elements. A hosted file-based loop is not a substitute for that kind of production. For a channel based on a fixed run of videos, compare the operational steps and rehearse whichever approach you choose.
Inspect the preview and verify the transition
A successful click is not the same as a verified change. Check OBS’s programme output after the switch: is the replacement visible, moving, and framed as expected? Listen for the expected audio. If the stream is live, check YouTube’s Live Control Room preview as well, while recognising that monitoring views may not reflect every viewer’s experience at precisely the same moment.
During rehearsal, note what happens at the change point. Does the new file begin at the start or resume where it last stopped? Does the old scene remain visible briefly? Does the audio change when expected? Does the source reload? Do not assume the answers from one source or computer apply to another; verify the particular combination you will use.
If there is a brief blank, inspect the source’s inactive behaviour and the media itself, then repeat the test. You may prefer not to close the file when inactive, if your setup has enough resources and that behaviour fits your use. That is a trade-off to test, not a universal fix. OBS documents a reload delay possibility for inactive Media Sources, but does not quantify it or guarantee how long any change will take.
Keep a simple change checklist beside the controls: current scene, replacement scene or file, expected audio, and a fallback. For a devotional channel, for example, confirm the next bhajan file and its audio before moving from the current loop. For a shop promo loop, make sure the replacement has the current hours and offers before it becomes the visible output. The point is to catch content mistakes before switching, not to predict a transition time.
If viewers report a problem, separate the checks. First verify that OBS is still outputting. Next check the active scene and source status. Then check the file path, playback and audio. Only consider ending or restarting the YouTube event if you actually intend to stop the broadcast or have diagnosed a broader connection problem; it is not the routine step for changing a video.
Plan a repeatable change process
For occasional updates, a prepared replacement scene is usually easier to reason about than modifying a live source under pressure. Give scenes and files clear names, keep the current one available as a fallback, and record the order if the channel uses a playlist. A small written procedure helps when another person has to make the change without knowing the original setup.
For recurring schedules, decide whether each change should be manual or automatic before building the workflow. Manual control lets you inspect each replacement, but someone must be present. A playlist can advance through files without a scene switch each time, but its order, loop and shuffle settings must reflect the intended programme. Neither method removes the need to test the actual assets.
If the change is part of a larger continuous programme, a countdown between videos may make a planned break visible, but it is a separate piece of content and should also be tested. If your workflow uses OBS on Linux, the OBS Linux rerun setup may be relevant to the broader configuration; it does not change the distinction between selecting content and ending a YouTube event.

FAQ
Can I change the video without ending the YouTube live event?
Yes, if you change the content in OBS while keeping its stream output and the YouTube event running. YouTube’s end control is for ending the broadcast, not for selecting a different local file. Rehearse the change because the documentation does not guarantee a gap-free result.
Should I use Media Source or VLC Video?
Use Media Source for one local file, including a file you want to loop. Use VLC Video when you want a playlist of several files; VLC must be installed, and the OBS and VLC bitness must match. Check ordering, loop and shuffle behaviour before going live.
Why might a scene switch show a blank moment?
A Media Source configured to close its file when inactive can take time to reload when it becomes active again. Other file or source conditions may also affect what you see, so test the exact transition. Do not assume a particular setting guarantees seamless switching.
Does YouTube automatically change the video when I edit a channel playlist?
No. The local files in an OBS source or VLC playlist are separate from a playlist on your YouTube channel. OBS sends the selected media in its encoder output, so make and verify the content change in the encoder.
