A playlist file can keep a sequence of local videos playing in OBS while OBS sends the programme to YouTube. The practical setup is an OBS VLC Video Source: install the matching VLC version, add your files in order, enable Loop Playlist, and connect OBS to YouTube with the stream URL and key.
That gives you repeating playback, not a guarantee that one YouTube broadcast will remain live indefinitely. You still need to check the preview, start the scheduled stream, watch for failures, and understand that YouTube documents automatic archiving only for streams under 12 hours.
What a playlist can and cannot do
A local playlist controls what OBS plays. It does not create a YouTube playlist, extend YouTube’s documented broadcast behaviour, or provide a recovery plan when the computer, network connection, OBS process or ingest connection fails.
For example, you might prepare six bhajans, a set of study videos, or several hours of an ambience programme. OBS can play those files one after another and return to the first file when it reaches the end. YouTube receives the resulting video feed as a live broadcast and does not need to know that the source is a playlist.
This distinction matters because “continuous” can describe two different things:
- Continuous local playback: OBS moves from one file to the next and repeats the list when looping is enabled.
- Continuous live operation: the computer, OBS, network connection and YouTube broadcast all remain healthy for the period you need.
The first is a setting. The second is an operating requirement with several points of failure. Looping does not restart OBS after a crash, restore power after an outage, or repair an interrupted connection. It also does not establish that YouTube will accept one broadcast without limit.
Before building the playlist, confirm that you have the right to use each file in a public livestream. A channel carrying devotional recordings, music, news clips or lectures can still receive a copyright claim even when the files were purchased or downloaded legitimately. For a radio-style channel, the copyright claims checklist for YouTube livestreams is a useful preparation step.
A playlist is also not the same as a scene collection. A scene collection stores OBS layouts and sources. The VLC Video Source stores the media list and its playback controls. You can use both together if you need an overlay, logo, clock or now-playing panel, but start with the simplest source that proves the media plays correctly.
Install VLC before adding the source
OBS’s VLC Video Source depends on VLC being installed on the same computer. If VLC is missing, the source may not appear in OBS, or it may not work as expected. Install VLC first, then restart OBS if OBS was already open.
The bitness must match. If you are using 64-bit OBS, install 64-bit VLC. Do not assume that installing any VLC package is sufficient. The OBS documentation for media sources specifically calls out the matching 64-bit requirement for 64-bit OBS. You can read the current OBS Media Sources documentation before installing so that the source and installation match the software already on your computer.
A sensible installation sequence is:
- Open OBS and note whether your installation is 64-bit.
- Install the corresponding VLC version.
- Close and reopen OBS.
- Create a test scene rather than changing the scene used for an important broadcast.
- Check whether VLC Video Source is available in the source list.
Keep VLC installed in its normal location unless you have a reason to change it. If OBS still cannot use the source after installation, check that both applications have the same architecture and that you restarted OBS. Reinstalling OBS without checking the VLC match can leave the original problem unchanged.
You do not need VLC open as a separate player for this workflow. VLC supplies the playback component that OBS uses for the source. Your task is to install the required application, select the files in OBS, and test the result there.
Add your files to a VLC Video Source
Open OBS and create or select the scene that will carry the programme. In the Sources panel, select the plus button and choose VLC Video Source. Give the source a descriptive name such as “Main playlist” rather than accepting a generic label. This becomes useful when you later add a logo, background or fallback source.
In the VLC Video Source properties, use the playlist area to add your media files. Choose the files in the order in which you want them to play. For a devotional channel, that might be a morning sequence followed by a longer evening set. For a study channel, it might be a collection of lessons arranged from introductory material to revision.
The files should be available on the computer whenever OBS is running. If they are on a removable drive, the drive must remain connected and retain the same path. If they are on a network location, a temporary network problem can prevent the next file from opening. Local storage is easier to test because it removes one dependency from the playback chain.
After adding the list, check the preview. The source should display the first file and produce audio if the file contains an audio track. Move through the list by allowing a short file to finish, or use a small test playlist rather than waiting for a long programme. Confirm all of the following:
- each file opens rather than showing a blank or black source;
- the aspect ratio is acceptable inside the scene;
- the audio is audible and not heavily clipped;
- the next file starts when the previous one ends;
- filenames and order match the programme you intended.
Do not make several changes at once while testing. If you alter the files, scene layout, audio filters and output settings together, it becomes harder to identify why a transition or sound problem occurred.
Video formats and codecs can behave differently even when two files share the same filename extension. If a file fails in the VLC Video Source, test it in VLC itself and then test a known-good file in OBS. Where conversion is needed, keep a copy of the original and follow a deliberate format workflow such as this guide to converting videos for 24/7 YouTube streaming in HandBrake.
Enable Loop Playlist
In the VLC Video Source properties, enable Loop Playlist. This tells OBS to return to the beginning of the list after the final item has played. It is the setting that turns a finite group of files into repeating local playback.
Use shuffle only if you actually want a random order. A fixed order is easier to audit and easier to explain to viewers. It also helps when you need to locate a particular item after a claim, complaint or scheduling question. If you run a lofi or ambience station where repetition is less structured, shuffle may be useful, but test the behaviour before using it for a public broadcast.
Looping applies to the playlist source, not to every part of your OBS production. If you have a separate media source, browser source or scene transition, those elements may have their own behaviour. A clock overlay can continue while the video changes, but an overlay that depends on a particular scene may disappear if you switch scenes.
Watch at least one complete file transition in the test scene. The point is not to prove that a broadcast can run forever. It is to confirm that the next file loads, the audio does not pause unexpectedly, and the source eventually returns to the first item. If the playlist contains long files, create a short test list from representative files before testing the complete programme.
You can use OBS’s audio mixer to check levels, but avoid setting the programme by looking only at one file. Different recordings may have different loudness. A devotional track, spoken announcement and ambience recording can sound uneven even when OBS shows similar meter movement. A consistent production may require preparing the files before they enter the playlist rather than relying on the mixer to fix every difference.
If the list does not move to the next file, first confirm that the source is a VLC Video Source rather than a different media source. Then check that the files are present, readable and listed in the intended order. If the YouTube stream stops when you replace an item, compare the symptoms with this guide to YouTube live streams stopping after changing a playlist before changing the whole setup.
Connect OBS to YouTube Live
YouTube treats OBS as encoder software. In YouTube Studio, create or open the live event in Live Control Room and copy the stream URL and stream key shown there. The exact labels can change as YouTube updates Studio, so use the current YouTube encoder setup instructions as the reference for the screen you see.
Keep the stream key private. Anyone who obtains it may be able to send a feed to the associated live setup. Do not paste it into a public tutorial, screenshot, shared document or chat message. If you think it has been exposed, use YouTube’s available key-management controls rather than continuing with a key you no longer trust.
In OBS, open Settings, then Stream. Choose the appropriate YouTube service if it is available, or enter the server details and stream key according to the connection method YouTube provides. Save the settings and avoid starting the public broadcast until the video, audio and event details are ready.
The connection has two separate parts:
| Part | What it controls | What to check |
|---|---|---|
| VLC Video Source | The files and their playback order | Files open, transitions work, Loop Playlist is enabled |
| OBS to YouTube connection | The feed sent to the live event | Correct server details, private stream key, correct event |
Keeping those parts separate helps with troubleshooting. If the preview is blank, the problem may be the source or output rather than the playlist order. If the source plays locally but YouTube shows no incoming feed, inspect the OBS connection and the event selected in Studio.
Before you begin, check that live streaming is enabled on the channel. YouTube says first-time enablement may take up to 24 hours. Do not schedule an important launch on the assumption that approval will be immediate. Check the current status in YouTube Studio and allow time for the account-level process.
Do a private or otherwise limited test where appropriate for your channel. Check the result from another device, not only the OBS preview. Confirm that the picture is moving, audio is present, the title and visibility are correct, and the correct event is receiving the feed.
Wait for the preview, then start the scheduled stream
Starting OBS is not always the same as making a scheduled YouTube event public. For a scheduled stream, start streaming in OBS and wait for YouTube Live Control Room to receive the feed. YouTube’s documented workflow then has you wait for the preview and select Go live when the preview is ready.
This pause is useful. It gives you a chance to catch the wrong scene, missing audio, incorrect title, accidental test footage or a playlist that has not loaded before viewers see it. Use it as a final inspection rather than clicking through the process automatically.
A practical launch sequence is:
- Open the scheduled event in YouTube Studio.
- Open OBS and confirm the intended scene is visible.
- Start the stream from OBS.
- Return to Live Control Room and wait for the incoming preview.
- Check the preview, audio indication, title, visibility and event details.
- Select Go live when YouTube indicates that the preview is ready.
- Watch the live page from a separate device for the first part of the broadcast.
If the preview does not arrive, do not repeatedly press buttons without checking the cause. Confirm the stream key and server details, check the OBS status, inspect the source preview and look for a network or firewall issue. A local playlist can play normally while the encoder is not sending a usable feed to YouTube.
For a channel that must operate unattended, test the complete start and stop procedure before relying on it. Include opening the computer, launching OBS, checking the source, starting the encoder and completing the YouTube event. If another person will operate the channel, write these steps down in the order they appear on screen.
Plan for the parts looping cannot protect
A computer-based OBS setup gives you control over the files and scene, but it also makes the computer part of the broadcast path. A power cut, operating-system update, sleep setting, overheating, storage failure, accidental restart or home broadband interruption can stop the feed. Loop Playlist does not address those events.
Disable sleep and automatic shutdown on the streaming computer, but do not treat that as a complete reliability plan. Schedule operating-system updates outside the broadcast window where possible. Keep the machine ventilated, leave enough storage for logs and temporary files, and use a stable wired connection if one is practical.
Monitor the YouTube event from another device during the periods that matter. For example, a local news loop may need checking before a morning audience arrives, while an overnight ambience channel may need a check before you leave and again when you return. Monitoring tells you that the public feed is present; it does not prove that every file in the playlist is suitable.
If you need restart handling or do not want to leave a personal computer running, compare the operating model rather than assuming that all 24/7 options behave alike. The guide to running a 24/7 stream without a PC explains the central question: what is actually responsible for keeping the feed active when your own computer is off.
A cloud-based workflow can remove the need to keep your computer switched on, but it does not change YouTube’s broadcast rules or your responsibility to check the content. StreamNeo is designed for the narrower problem of uploading a finished video, connecting it to your YouTube channel, and having the cloud-run broadcast monitored and restarted automatically if it drops.
For the local OBS approach, keep a written recovery plan. It should say where the files are stored, which scene is the main scene, where the stream key is managed, how to confirm the YouTube event, and who checks the public stream. If the channel matters overnight, a second person should know how to perform the basic check rather than relying on one operator’s memory.
Understand YouTube’s archive limit
YouTube’s documented archive statement is narrower than many “24/7 playlist” guides suggest. YouTube Help says that all streams under 12 hours will be automatically archived. That tells you about automatic archiving for streams below that duration. It does not promise that a single broadcast can remain live indefinitely, and it does not say that a looping playlist creates an unlimited archive.
Treat 12 hours as a documented archive boundary, not as a guarantee about every aspect of a long broadcast. The reviewed YouTube guidance does not establish that one broadcast may run without limit, nor does it guarantee that a playlist loop will remain uninterrupted. If you need a long-running channel, plan how you will handle the end of an event, a reconnect, a new scheduled broadcast or a manual review of the archive.
YouTube also documents a separate HLS ingestion path with technical requirements such as 1–4 second segments, HTTPS requests, no byte ranges and a rolling playlist with no more than five outstanding segments. You do not need those HLS settings simply to loop local files through OBS. They apply when you deliberately choose HLS ingestion, and YouTube notes that HLS has higher latency than RTMP. See the current YouTube HLS setup documentation if HLS is the path you are evaluating.
Do not switch to HLS because the word “playlist” appears in its documentation. An HLS media playlist is an ingestion format with segment and request rules. It is not the same thing as selecting a collection of MP4 files in an OBS VLC Video Source.
YouTube’s Live Streaming API also distinguishes a broadcast from a stream. Its documentation describes these as separate resources and includes scenarios involving multiple broadcasts and stream resources. That model can help when designing a larger publishing workflow, but it is not evidence that the API provides a simple end-user playlist-file solution. For an OBS setup, follow the encoder and event workflow you can test directly.
The safest description for your channel is therefore precise: OBS can loop a local playlist while it is running, and YouTube can receive that output as a live broadcast. Neither statement promises indefinite duration, uninterrupted 24/7 operation or automatic archiving of broadcasts beyond YouTube’s documented conditions.

FAQ
Can OBS loop several MP4 files into one YouTube livestream?
Yes. Install the VLC version that matches OBS, add the files to an OBS VLC Video Source, arrange them in order and enable Loop Playlist. Test each transition before sending the feed to a public YouTube event.
Does Loop Playlist make a YouTube stream permanently live?
No. It repeats the local files while OBS and the surrounding setup continue working. It does not guarantee an uninterrupted broadcast, unlimited duration or recovery from computer, network or YouTube-side problems.
Why is VLC missing from my OBS source list?
VLC must be installed for the VLC Video Source to be available. If OBS is 64-bit, install 64-bit VLC, then restart OBS and check the source list again.
What happens to a long YouTube livestream archive?
YouTube Help states that streams under 12 hours are automatically archived. That is not a promise that one broadcast can run indefinitely or that longer looping broadcasts will be archived automatically, so check YouTube’s current guidance before planning around an archive.
