If you want to loop a prerecorded video on YouTube Live from Linux, use OBS Studio as the encoder, add the file as a Media Source, and enable Loop. For several files, use OBS's VLC Video source, add the playlist, and enable Loop Playlist.
That setup repeats the local media and sends it to YouTube as a live broadcast. It does not, however, explain every case where a player stalls or a playlist refuses to advance. First identify which part is failing, then test the device, browser, application, connection, and live delay separately.
Identify what is actually failing
There are two problems that are often described with the same words. A viewer may say that the video is “stuck” when the live player has stopped receiving data, or when the picture is still changing but the programme has not moved to the next item in a playlist.
A stall or lag usually looks like a frozen picture, a loading spinner, repeated buffering, missing audio, or a live player that falls further behind. The problem may be the viewer's connection, browser, device, or the incoming broadcast.
A failed transition happens when one file reaches its end but the next file does not begin, or when a single file reaches its end and does not restart. This points more directly towards the source configuration, playlist handling, media decoding, or the encoder process. It is not the same as a slow viewer connection.
Check the distinction with a simple observation. If the timestamp or picture continues to change but the expected next video never appears, investigate the source and playlist. If the player stops receiving a moving picture altogether, investigate delivery and playback first. If only one viewer sees the problem, do not assume that the broadcast source is defective.
This distinction matters because general YouTube playback troubleshooting can help with buffering, but it is not proof of a universal fix for playlist progression. Likewise, changing an OBS playlist setting will not repair a viewer's weak Wi-Fi connection.
Before changing several things at once, write down what happened. Note the file that was playing, whether the audio stopped as well, whether OBS's preview continued, and whether another device showed the same behaviour. These observations make the next test useful rather than turning the setup into a collection of unexplained changes.
Configure the Linux loop before troubleshooting
For one repeating video, install OBS Studio for your Linux distribution and create a scene. Add a source, choose Media Source, select the local video, and enable Loop. OBS documents Media Source and its looping behaviour in its Media Sources documentation. The exact menus can vary slightly between OBS versions, but the important setting belongs to the source, not to YouTube's viewer-side player.
Check the preview after adding the file. Let the beginning play, move through the middle, and allow it to reach the end if the file is short enough for a practical test. A loop that appears correct in the first few seconds may still fail when the file reaches its final frame or when its audio stream ends.
For multiple videos, add a VLC Video source instead. Create the playlist in that source, add the files in the order you want, and enable Loop Playlist. OBS says that VLC must be installed for this source type to appear. It also specifies that a 64-bit OBS installation needs 64-bit VLC, so installing a different architecture may leave you with a missing or unusable source.
Use the single-file Media Source when you are repeating one long devotional recording, ambience video, or study session. Use VLC Video when the broadcast needs to move between separate tracks, news clips, or announcements. The choice is about source management rather than stream quality. Both still require OBS to encode the scene and send it to YouTube.
Once the preview behaves as expected, open YouTube Studio's Live Control Room and create or schedule the stream. Copy the server URL and stream key into OBS's streaming settings, then start the encoder. For a scheduled broadcast, YouTube's encoder instructions say to wait for the preview and then select Go live.
Prefer the RTMPS URL when the installed encoder supports it. YouTube describes RTMPS as RTMP carried over TLS/SSL and explains how to reveal the RTMPS address in Live Control Room in its RTMPS guidance. Treat the stream key as a secret. Someone who obtains it may be able to send content to that stream, so do not paste it into screenshots, public notes, or support forums.
OBS recommends checking the output and audio settings and making a short test before the first real broadcast. Its Quick Start Guide is useful here because it separates sources, audio, output, and the test itself. A short test is not evidence that an overnight broadcast will never fail, but it can reveal a file that will not decode, silent audio, a wrong scene, or an incorrect stream destination.
Check whether the problem is limited to one device
If you are watching the live stream while operating OBS, compare the OBS preview with YouTube on another device. For example, leave OBS running on the Linux computer and open the public stream on a phone using mobile data, then check it on a second computer if one is available.
If OBS's preview keeps moving and another device plays the stream normally, the original viewer device or its connection is the more likely cause. If OBS is also frozen, inspect the source and encoder rather than repeatedly refreshing the viewer page. If every device stops at the same point, record the time and the file that was playing.
Do not use a single successful phone test to conclude that the system is reliable. A phone may use a different network path, a different decoder, and a different adaptive playback decision from a desktop browser. The test is valuable because it narrows the fault, not because it proves that all viewers have the same experience.
For a channel that runs overnight, perform a local observation and a remote observation. The local check tells you whether OBS is still producing a moving scene. The remote check tells you whether YouTube is receiving and delivering that scene. If you cannot be present for the whole test, record the start time, the first transition, and the point at which the symptoms appear.
Also check whether the issue follows the account or the device. Sign in to the same YouTube account on another device only if the test requires it, but remember that the public playback page is a better test of what viewers receive. Creator controls and viewer playback do not always expose the same information.
Test another browser or supported device
A browser can be involved even when the broadcast is healthy. Extensions may modify the player, privacy settings may block a required script, and an old browser may have trouble decoding a particular combination of video and audio. Open the public stream in a current supported browser with extensions disabled for the test.
Use a private window only as a diagnostic comparison, not as a permanent operating method. It can remove stored site data and many extensions from the test, but it may also change sign-in and permission behaviour. If playback works there, re-enable changes one at a time until the cause is clear.
Try a second browser on the same device. This keeps the network and much of the hardware constant while changing the player environment. Then, if possible, try a different device on the same network. These comparisons help separate browser issues from device decoding issues and network issues.
If the problem appears only on one browser, update it and check its hardware-acceleration setting. Do not change several graphics settings without recording the original state. A browser change can affect power use, video decoding, and other pages, so restore the setting if it makes no difference.
If the stream plays in one browser but not another, do not describe that as proof that the playlist failed to advance. The playlist may have progressed correctly at the broadcast source while one player failed to render or request the next segment. Check the live output from another device before altering the OBS source.
If you are operating OBS through a desktop session, remember that the OBS preview is not a browser. A healthy preview shows what OBS is composing locally, while the public YouTube page shows what YouTube has received and what the viewer's player can decode. Both are useful, but they answer different questions.
Check the app, browser, file, and connection basics
Start with the least disruptive checks. Confirm that OBS is running the expected scene, the source is visible, and the audio meters move when audio should be present. Make sure the selected file still exists at the path recorded by the source and that a removable drive or mounted network location has not disappeared.
For a single file, confirm that Loop is enabled. For a playlist, confirm that the source is VLC Video, that the playlist contains the intended files, and that Loop Playlist is enabled. If VLC Video is missing, verify that VLC is installed and matches the architecture required by the OBS installation. Restarting OBS after installing VLC can also make the source available, but do not treat a restart as a fix until you retest the transition.
Test each file separately when a playlist is involved. One damaged file, unusual codec, variable frame structure, or unsupported audio stream can interrupt the sequence. A file extension alone does not prove that the installed OBS build can decode the contents. The practical test is to play that exact file through the exact source on the Linux machine that will operate the stream.
Keep filenames simple while testing. Avoid replacing files in place during a live session, and avoid changing the playlist while OBS is actively using it. Make a new test playlist if you need to compare versions. This gives you a known configuration to return to if the fault disappears and later returns.
Check the Linux host as well. Confirm that the machine is not suspending, losing its display session, running out of storage for temporary work, or being heavily loaded by another process. Watch CPU, memory, and disk activity during a transition. A computer can show a moving preview while still struggling to encode consistently, so inspect OBS's own status indicators rather than relying only on the picture.
Then check the upload connection. A speed test is only a snapshot, but it can reveal an obvious mismatch between the selected output and the available upload capacity. Watch for packet loss, brief disconnections, router reboots, and changes between wired and wireless networking. For an always-on channel, a stable wired connection is often easier to diagnose than a variable wireless one, but neither is a guarantee of uninterrupted broadcasting.
Keep output settings consistent while troubleshooting. Resolution, frame rate, bitrate, and audio settings affect the work Linux must do and the amount of data OBS sends. YouTube's encoder guidance explains that these values are set in the encoder and that YouTube creates viewer versions from the incoming stream. Choose settings your file, computer, and upload can sustain rather than copying a value intended for a different source.
If the stream is intended for an audience in India or elsewhere with mixed connection quality, remember that the viewer receives a YouTube-delivered version, not necessarily the exact local output you see in OBS. A clear local preview can coexist with buffering for one viewer. Conversely, a local decoding problem can make the operator think YouTube is at fault when the public stream is fine.
Account for live playback delay
Live video is not expected to reach every viewer at the same instant. There is a delay between OBS sending the encoded output, YouTube processing it, and the player displaying it. A viewer may therefore see the previous file for some time after OBS has already moved to the next one.
This is especially confusing when you are watching OBS on the Linux computer and YouTube on a phone. Compare events by their order rather than their wall-clock second. If the local preview changes from file A to file B, wait for the public player to catch up before deciding that the transition failed.
Use a distinctive test point, such as a title card or a spoken marker, rather than a subtle visual change. Note when the marker appears in OBS and when it appears on the public stream. The difference is the playback delay for that observation. It can vary with player conditions, so one measurement is not a permanent promise about the channel.
Do not repeatedly seek, refresh, or switch quality while trying to measure a transition. Those actions can alter the viewer player's position and make the comparison harder. For a clean test, leave the player alone, use the same device, and observe whether the next item eventually appears.
A delayed player can also make a short gap look like a failed loop. If the final seconds of one file contain a dark frame or silence, the viewer may think the stream has stopped even though the next file is already being processed. Inspect the source boundary in OBS and, where appropriate, edit the media to remove an unintended blank ending.
If your channel uses a scheduled stream, distinguish the preview stage from the public broadcast. YouTube's workflow may require you to start the encoder, wait for the preview, and select Go live. A viewer checking the public page before that handoff may not be seeing the same state as the operator in Live Control Room.
When general fixes do not resolve it
If the source still fails to advance after you have tested the exact files, confirmed the loop setting, compared OBS with the public stream, and ruled out one device or browser, stop changing random playback settings. At that point the useful question is which boundary fails: media decoding, OBS source handling, encoding, YouTube ingest, or viewer playback.
Create a smaller test that removes variables. Use one short, known-good file with Media Source and Loop enabled. If that works, add a second known-good file through VLC Video and test the playlist transition. If the two-file test fails while the single-file test works, focus on VLC, playlist entries, file compatibility, and the transition itself.
If the local preview stops, examine OBS logs and status indicators around the recorded time. Check whether CPU load, dropped frames, encoder overload, or a source error appears. The exact label depends on the OBS build and operating system, so record the message rather than guessing what it means.
If OBS remains healthy but YouTube stops receiving the broadcast, investigate the stream URL, RTMPS selection, stream key, upload connection, and firewall or router behaviour. YouTube's official RTMPS page includes checks for the URL scheme and discusses port 443 for some SSL errors. Apply those checks to the current documentation rather than relying on an old forum command.
If YouTube receives the stream but one viewer cannot watch it, return to the device and browser tests. A general playback fix may help that viewer, but it does not establish that the playlist transition is defective. Keep the two diagnoses separate in your notes and in any support request.
Do not publish a command-line recipe simply because it looks shorter than OBS. FFmpeg can be a reasonable Linux option for a headless workflow, but loop flags, realtime pacing, audio and video mapping, encoding, and reconnection behaviour need to match the installed build and the chosen input. If you want that route, verify the current FFmpeg manual and test it with the same discipline as an OBS setup. The guide to streaming multiple files with one FFmpeg command can provide useful context, but it should not replace validation on your machine.
There are also operational limits outside the loop setting. YouTube says first-time live-stream enablement may take up to 24 hours, so an account that has never streamed may not be ready immediately. YouTube also states that streams under 12 hours are automatically archived. Check the current YouTube Help page before planning a long broadcast, because account and platform guidance can change.
Finally, confirm that you have the necessary rights to the video, music, images, and spoken material. The OBS and YouTube setup steps do not grant permission to broadcast a recording. If your channel is based on devotional music, local news, ambience footage, or stock media, keep the licence or permission records available and review current YouTube policy before going live. The stock-footage licensing guide covers common traps, while YouTube's monetisation guidance for looped streams addresses a separate policy question from technical looping.
For a long-running channel, a local Linux computer is not the only operating model. It gives you direct control over OBS and the source files, but it also leaves power, updates, storage, network interruptions, and recovery in your hands. If the recurring problem is keeping the computer awake and restarting a dropped broadcast rather than configuring the media, StreamNeo removes that specific day-to-day burden by taking an uploaded video, connecting it to your YouTube stream, and handling automatic restart without your computer remaining switched on.

FAQ
Can OBS loop one video on Linux?
Yes. Add the file as an OBS Media Source and enable Loop. Test the exact file through the installed OBS build, because a supported extension does not guarantee that every codec combination will decode correctly.
How do I loop several videos in OBS?
Use the VLC Video source, add the files to its playlist, and enable Loop Playlist. VLC must be installed, and OBS documents matching 64-bit VLC with 64-bit OBS.
Why does YouTube appear to stay on the old video?
Live playback has a delay, so the public player may show the previous item after OBS has already advanced. Compare the OBS preview with another device and wait for the player to catch up before treating the transition as failed.
Will changing browser settings fix a playlist that will not advance?
It may fix buffering or rendering on one viewer device, but it is not proof of a source-side playlist fix. If the transition fails in OBS itself or on every public test device, investigate the media source, files, VLC installation, encoder, and YouTube ingest separately.
