For a playlist of original cartoons in OBS, add a VLC Video source, load the files into its playlist and leave Loop Playlist enabled. VLC must be installed in the architecture that matches OBS; the loop repeats local media, but it does not guarantee that YouTube receives an uninterrupted live stream.
This walkthrough covers file and rights checks, the VLC source controls, YouTube connection and a practical test. It is for a playlist of files you control or have permission to use, not a way to make unlicensed cartoons or music acceptable for a live broadcast.
Prepare Cartoon Files and Confirm Usage Rights
Put the cartoon files somewhere the computer running OBS can access them, and keep that location stable. A folder on the computer’s internal drive is usually easier to manage than a removable drive that may be unplugged or assigned a different drive letter after a restart. If you reorganise files after setting up the playlist, revisit the source and confirm each entry still points to a playable file.
Before building the playlist, check that you have permission for every element in every episode: animation, character art, dialogue, music, sound effects, opening and closing titles, and any artwork in overlays or thumbnails. “Original” can describe the animation while leaving the soundtrack, commissioned work or a contribution by another person subject to separate terms. Keep written permissions or licence details together with the project files so you can verify the intended use later.
YouTube says live streams are scanned for third-party content and may be interrupted or terminated if copyrighted material is identified. Its copyright guidance for live streams is worth checking before broadcast. Having a file on your computer, or having used it in another video, does not by itself establish permission for a continuous live stream.
Prepare the files before opening OBS. Use clear filenames and decide the intended order, such as episode-01.mp4, episode-02.mp4 and short-between-episodes.mp4. If you want a short ident between episodes, include it as its own file in the sequence. Watch the files from start to finish, checking for missing sound, blank frames, unexpected black endings and transitions that might be distracting when repeated overnight.
A playlist can only play the files it can read. Avoid relying on a cloud-synced placeholder that has not downloaded, a temporary export folder or storage that the computer may sleep or disconnect. If the cartoons have different dimensions or audio levels, test them in the actual OBS scene; VLC’s playlist feature does not make the episodes visually or audibly uniform.
For a broader prerecorded-stream workflow on a Windows computer, see this guide to streaming Hindi videos as a YouTube playlist. The same distinction matters here: prepare the media and ordering first, then verify the live delivery separately.
Install VLC for Your OBS Version
OBS’s VLC Video source depends on VLC being installed. If VLC is absent, the source may not appear in the add-source menu. Install VLC before configuring the playlist, and match its architecture to OBS: with 64-bit OBS, use 64-bit VLC. A 32-bit VLC installation is not the correct match for 64-bit OBS.
Check whether your OBS installation is 64-bit before choosing the VLC installer. In OBS, use the Help menu’s About option to view the version information, or check the installer or download you used. If the source is missing after installing VLC, close and reopen OBS so it can detect the installed application, then check that both applications have matching architecture. Avoid repeatedly adding Media Source when the requirement is a multi-file playlist; that is a different source with different controls.
Download VLC from its official project site, and OBS from the OBS Project. The OBS documentation on media sources explains the distinction between Media Source and VLC Video. Menu labels may shift between OBS versions, but the source roles remain useful: Media Source is built in and can loop a single local file; VLC Video provides a playlist for multiple files.
Add an OBS VLC Video Source
Open the scene that will carry the cartoons. In the Sources panel, select the plus button and choose VLC Video. Give the source a name that will still make sense later, such as “Cartoon playlist”. A descriptive name is helpful if the scene also contains a logo, subtitles, a background or other media.
If VLC Video does not appear in the source list, first confirm that VLC is installed and that its architecture matches OBS. Restarting OBS after installation is a useful check. If a source already exists but reports missing media, inspect its playlist paths and confirm that the files are still where OBS expects them to be.
The source is not the whole broadcast scene. Arrange its size and position in the preview, then add any other elements that genuinely belong in the stream. For example, a small channel mark or a restrained “episodes repeat” note may help viewers understand the format. Keep an eye on how overlays cover subtitles or important action. Mute or remove sources that should not contribute audio, and listen to the final scene rather than assuming the cartoons’ own tracks will be the only sound.
OBS’s built-in Media Source is the simpler choice if you are playing one file repeatedly. Its Loop control repeats that one file. For several episodes in sequence, VLC Video is the playlist-capable source. This comparison is useful before configuring anything:
| Choice | Best fit | Playback control | Dependency and behaviour |
|---|---|---|---|
| Media Source | One local cartoon file | Loop repeats the single file | Built into OBS; no VLC installation needed |
| VLC Video | Several cartoon files | Playlist can repeat as a group and can shuffle | Requires VLC installed in an architecture matching OBS; by default it stops when hidden and restarts when visible |
The OBS media sources documentation describes the controls, including the playlist loop option and source visibility behaviour. If you are choosing between playback approaches beyond OBS, this overview of automatic video playlists for YouTube Live covers a different, more technical route. It is not necessary to install FFmpeg just to use VLC Video in OBS.
Load the Playlist and Enable Loop Playlist
Open the properties for your VLC Video source. Add the local cartoon files to its playlist, either one at a time or by selecting several files in the file picker. Confirm the displayed order. If the source lets you move entries up or down, use that list to arrange the sequence rather than renaming files and assuming the player will sort them as intended.
Enable Loop Playlist. OBS describes this control as determining whether the source restarts after it has run out of media files. With it enabled, the playlist begins again after the final item finishes. This repeats the listed files; it does not repair a missing file, correct a bad export or keep the broadcast connected to YouTube.
To verify the setup, start playback in the preview and watch at least one transition between files. Check that the next cartoon starts, that the sound changes as expected and that the final item returns to the first item when the list ends. For a long playlist, you do not need to sit through every episode during setup, but do spot-check each file and test the transition around the end of the list before depending on it.
Keep a note of the playlist order and the folder location. If you replace an episode with a new export, reopen the source properties and check that the updated file is in the list. A filename that stays the same can still conceal an export with a different soundtrack or an unwanted end card, so play the replacement before broadcast.
If the channel’s schedule includes material other than cartoons, plan how those assets enter the playlist instead of relying on a separate scene that may behave differently. For example, a recurring break card can be a video file in the list, or a still graphic in a scene transition. Test whichever design you choose. A playlist is a sequence of media files, not a schedule manager that knows what time of day it is.
Check Shuffle and Playback Behaviour
Shuffle Playlist is off by default. Leave it off if you want episodes to run in the order shown, which is usually the sensible starting point for a series with a narrative sequence. Turn it on only if a changing order is intentional, such as a collection of independent shorts. Check the resulting behaviour in the preview rather than assuming the order you see in the properties will match shuffled playback.
VLC Video’s documented default is to stop when its source is not visible and restart when it becomes visible. This matters if you have multiple scenes: switching away from the cartoon scene can stop its playback, and switching back can start it again. If you plan to use scene changes, test them while monitoring audio and picture. A source that restarts on visibility may begin an episode from its start rather than resume at the point you expected.
Make sure the playlist source is visible in the active scene when you intend it to play. Also check that it is not hidden under another full-screen source. A black preview can come from a hidden source or a scene layout issue as well as a media problem; use the eye controls in the Sources panel and confirm the correct scene is active.
A loop in the local player is only one link in the chain. OBS still needs to keep running, the computer must stay awake, the connection must carry the configured stream, and YouTube must continue to accept it. If OBS closes, the computer restarts or the network drops, Loop Playlist does not restart the live broadcast by itself. For the particular problem of an encoder stopping, see what happens when an OBS stream crashes.
Connect OBS to YouTube Live
In YouTube Studio, create or schedule a live stream and obtain its stream key through the live control room. In OBS, open Settings, then Stream, choose YouTube as the service and enter the stream key using the connection method shown in your OBS version. Treat the key as a password: do not put it in a public screenshot, share it in a support post or leave it visible on a recording. If you suspect it has been exposed, replace it in YouTube Studio and update OBS.
Check that your channel is eligible to go live before you plan a long broadcast. YouTube’s live-streaming eligibility guidance says the channel must be verified and must not have live-streaming restrictions in the preceding 90 days. YouTube also requires live content to follow its Community Guidelines and Terms of Service. Confirm the current requirements in YouTube’s official guidance rather than treating a past successful stream as proof that nothing has changed.
Choose encoder settings with the actual upload connection in mind. YouTube’s encoder settings guidance provides recommended bitrate ranges that vary with codec, resolution and frame rate. These are not one universal setting for every computer or connection. Select a combination your upload can sustain consistently, and use the current table for the codec and picture settings you intend to send.
OBS recommends a wired connection where practical; Wi-Fi can be unstable, and dropped frames can indicate that the connection cannot sustain the selected bitrate. An Ethernet cable is a useful option if the computer is near the router and Wi-Fi is unreliable, but buying one is not a substitute for testing the connection or choosing suitable settings. If you stream over a mobile or shared connection, consider whether its capacity changes at busy hours. A stream that looks stable during a quiet afternoon may behave differently overnight.
For a connection-specific walkthrough, see running a prerecorded stream on Airtel Broadband. The important practice is to test from the same location and connection you intend to use. Watch OBS’s dropped-frame indicators and YouTube’s stream-health display during the test. A local preview confirms that OBS can render the scene; it does not confirm that viewers receive a healthy stream.
Test the Whole Scene and Plan for Monitoring
Before the first long broadcast, run a short private or unlisted test with representative audio, movement and transitions. YouTube explicitly advises creators to test before starting a live stream. Check the scene in OBS and the received output in YouTube’s control room. Confirm picture dimensions, sound levels, the playlist advancing, the loop returning to the first item and any transition or overlay behaviour.
A short test can reveal obvious problems, but it cannot prove a setup will run continuously for a day or longer. Treat the test as a way to catch configuration errors, not as evidence of guaranteed uptime. Check that the computer’s power settings will not put it to sleep, that the media drive remains available and that you know how to inspect OBS and YouTube stream health while the broadcast is running.
Decide what you will do if the stream health indicator changes or the output stops. Keep OBS open on the correct scene, and know where the stream key settings and YouTube control room are. If someone else is responsible for checking the stream, make sure they can identify the active scene and understand which warning needs attention. The local playlist may still be moving even when the connection to YouTube has failed, so distinguish “media is playing” from “viewers are receiving the live stream”.
If you cannot leave a computer and network connection running and monitored, an OBS loop may not be the right operating arrangement. A cloud-based file-to-live workflow can remove the need to keep your own computer on for playback, though it remains YouTube-only and you still need to prepare rights-cleared files and check the channel. StreamNeo turns an uploaded video into a 24/7 YouTube live stream, which addresses the specific burden of leaving OBS and your own computer running for the broadcast; it does not make a local OBS loop more reliable or guarantee YouTube delivery.
A different channel format may also suit a less continuous schedule. For instance, a 24/7 cabin rain ambience stream involves its own media and monitoring choices, even though the broad distinction between playback and live delivery remains the same. Choose an approach based on the files, operator time, connection and recovery process you can actually support.
Before committing, compare the operating options on the pricing page. When the file and channel are ready, start free — 24-hour trial, no card.
FAQ
Does VLC Video repeat one cartoon or the whole playlist?
VLC Video can play multiple files in a playlist, and Loop Playlist restarts the playlist after its items finish. For just one file, OBS Media Source has its own Loop control. Use the source that matches the number of files you need to play.
Why can’t I find VLC Video in OBS?
VLC must be installed for the source to appear. Make sure its architecture matches OBS, including 64-bit VLC for 64-bit OBS, and restart OBS after installing VLC. If it still does not appear, recheck the application versions and installation rather than assuming Media Source has the same playlist controls.
Does Loop Playlist keep a YouTube stream live all day?
No. It repeats local media inside OBS, but the broadcast also depends on OBS, the computer, the network and YouTube’s live service. Test the whole path and monitor stream health; a successful short test does not establish uninterrupted delivery for a full day.
Can I loop cartoons made by someone else?
Only if you have the rights or permission required for the intended use, including any music, sound effects and other third-party elements. YouTube may interrupt or terminate a live stream when it identifies third-party copyrighted content. Check current official guidance and your licences before going live.
