For several MP4 files, the practical local setup is OBS Studio with its VLC Video source. Install VLC first, add the files in the required order, leave Shuffle Playlist off, enable Loop Playlist, and then verify the feed in YouTube Live Control Room.
This is different from OBS Media Source, which is designed for one file at a time. A local setup gives you control over scenes and playlists, but the computer, files, power and internet connection must remain available while the stream runs.
Check channel readiness and install VLC
Before building the playlist, make sure the YouTube channel can go live. YouTube may require initial live-stream activation, and YouTube's encoder setup guidance says that activation can take up to 24 hours. Do this before you are ready to broadcast, rather than discovering the restriction after preparing the files.
In YouTube Studio, open the live section and create or schedule a stream. You do not need to publish it immediately. The important part is to reach Live Control Room, where YouTube provides the connection details and shows the incoming encoder feed.
For the local playback software, install OBS Studio and VLC Media Player. OBS's media sources documentation identifies VLC Video as the source for playing a playlist of media files. VLC must be installed for that source to appear in OBS. If you use 64-bit OBS, install the 64-bit version of VLC so the two applications match.
After installing both applications, restart OBS if it was already open. Then check the source list when you add a source. If VLC Video is missing, do not substitute the single-file Media Source and assume it will handle the playlist. Check the VLC installation and its bitness first.
Keep the MP4 files in a stable folder. Avoid moving, renaming or disconnecting that folder after the stream is configured. A playlist is only useful while OBS can still reach every file in it.
Create an OBS scene and add VLC Video
Open OBS and create a new scene for the channel. Give it a useful name such as “Main playlist” rather than leaving it as Scene 1. A named scene is easier to identify later if you add an emergency holding image, a title card or a second programme layout.
In the Sources panel, select the add button and choose VLC Video. This is the important choice for multiple local MP4 files. The VLC Video source exposes playlist controls, while Media Source is the simpler option for a single file with its own loop setting.
Add the files from the VLC Video properties window. You can normally select more than one file, or add files one at a time depending on your operating system. The order shown in the playlist is the order OBS will attempt to play them, so review it before closing the properties window.
Set the source to fit the canvas if the video does not fill the preview. Different aspect ratios may produce black bars or cropping. That is a presentation decision, not a playlist failure. If a devotional video is 16:9 and a portrait clip is added later, decide whether the portrait clip should sit inside the canvas, be cropped, or be replaced with a version prepared for the channel format.
Do not judge the setup only from the first file. A source can display the opening video correctly while a later file has a missing path, unsupported audio layout or a different frame size. The transition between files is part of the test.
Add MP4 files in the intended order
Treat the playlist as a running programme rather than a pile of files. Put the opening item first, then arrange the remaining items according to the experience you want viewers to receive. For a bhajan channel, that might mean an opening title card, a sequence of devotional videos, and a closing or reset card. For a study channel, it might mean a short introduction followed by longer sessions.
Use clear file names before importing them. A naming pattern such as 01-opening.mp4, 02-morning-bhajan.mp4 and 03-evening-bhajan.mp4 makes mistakes easier to spot. The names do not control OBS unless you use them to arrange the playlist, but they make later maintenance less error-prone.
Keep the source files available on the same computer. If the files are stored on a removable drive, confirm that the drive has a stable connection and will not sleep or disconnect. A network folder adds another dependency that is difficult to diagnose at two in the morning.
Mixed media can work, but it deserves testing. Differences in resolution, frame rate, codec, audio channels or audio sample rate may become visible only at a transition. A black frame, a silent item or a stalled source can make the YouTube stream appear broken even though OBS itself is still running.
If a file fails, remove it from the live playlist and test it separately in a normal media player. Re-export or replace it if necessary. Keep an unchanged backup of the original files, and use a separate working folder for versions prepared for the livestream.
For spoken programmes, transitions deserve the same attention as video. If one MP4 ends with silence and the next begins several seconds later, viewers will hear a gap even though the playlist is technically looping. The guidance in this article about preventing silence between podcast episodes is also useful when your playlist contains talks, readings or news segments.
Set playlist order and enable looping
Open the VLC Video source properties again and inspect the playlist from top to bottom. Confirm that the first item is actually first, especially if you added files in several batches. A fixed order matters for channels that follow a daily schedule or want a predictable sequence for repeat viewers.
Leave Shuffle Playlist disabled when order matters. Shuffle can be useful for a music or ambience channel that does not need a fixed sequence, but it makes testing and troubleshooting harder. If a particular file has a problem, you want to know exactly when it will appear and what played immediately before it.
Enable Loop Playlist. This tells the VLC Video source to return to the beginning after the final item. It is the setting that turns a finite list into a repeating programme. Do not confuse it with the Loop setting on OBS Media Source, which applies to a single media file rather than a multi-file VLC playlist.
Save the source properties and watch the preview through at least one transition. If the list is short, watch a complete cycle. If it is long, test the final item and the return to the first item before leaving the setup unattended. The first loop is where missing files, inconsistent audio and unexpected ordering are most likely to appear.
You can add overlays, text or a logo as separate OBS sources. Keep those additions simple until the playlist itself is stable. Every extra browser source, plugin or animated element introduces another thing to inspect when the output does not behave as expected. The OBS plugin guide for automating a 24/7 YouTube video stream can help when you have a specific automation need, but a basic VLC playlist is the better starting point.
Choose output settings for the YouTube feed
Your output settings should match the source material and the upload connection, not a setting copied from an unrelated tutorial. YouTube's current encoder guidance recommends constant bitrate, a two-second keyframe interval, and RTMPS when available. Its table varies by codec, resolution and frame rate.
For H.264, the current YouTube guidance lists 10 Mbps for 1080p at 30 frames per second and 17 Mbps for 1080p at 60 frames per second. It also recommends 128 Kbps for stereo audio. These figures are attributed to YouTube's encoder-settings page accessed in October 2026; consult the current table before choosing another resolution, frame rate or codec.
In OBS, open Settings and review the Stream and Output pages. Select YouTube if it is available in the service list, or enter the server URL and stream key supplied by Live Control Room. In the output section, use CBR and set the keyframe interval to two seconds if those are the settings appropriate to your chosen YouTube output.
The upload connection must sustain the total output while other household or business activity is taking place. A connection that appears adequate during a quiet test may behave differently when someone starts a video call, uploads files or uses a shared mobile connection. If you are unsure, reduce the output requirement by choosing a sensible resolution and frame rate for the source instead of forcing a higher setting.
The OBS bitrate guide for a 24/7 YouTube stream with Indian broadband is relevant if your channel is operating on a variable home or office connection. It cannot replace a test from your own location, but it gives you a way to think about bitrate, overhead and connection changes before you leave the stream running.
Connect OBS to YouTube securely
In Live Control Room, copy the stream URL and stream key into OBS, or use the YouTube service selection if OBS presents it. The key connects your encoder to the YouTube event, so treat it as private. Do not paste it into a public document, screenshot or support forum.
YouTube distinguishes the encoder connection from the public details viewers see. Check the title, description, visibility and scheduled time in Live Control Room before going live. For a test, unlisted visibility can let you inspect the feed without immediately presenting it as a public programme, subject to the options YouTube currently provides for your channel.
Start OBS's stream output and wait for YouTube to receive the signal. Do not assume that seeing video in the OBS preview means YouTube is receiving the same feed. OBS is showing its local canvas; Live Control Room is the place to confirm the platform-side input.
If the stream does not connect, check the copied key, selected service, server URL, firewall and upload connection. Do not regenerate the key repeatedly without recording which key is currently in OBS. A mismatch between the active YouTube event and the key in OBS is a common source of confusion.
Verify picture, sound and stream health
Use Live Control Room's preview to check the actual incoming picture. Look for the correct scene, readable overlays, expected framing and a moving image. Then listen for audio. A video can look normal while the selected files have no audio, the wrong audio device is active, or the level is too low for viewers.
YouTube recommends testing with both audio and movement and checking stream health. Follow that advice before relying on the broadcast. Watch the health indicators for a while rather than stopping at the first successful preview frame. A short test that never reaches a playlist transition cannot reveal a problem in the second or third file.
Check the OBS statistics window as well. Look for dropped frames, rendering or encoding strain, and an output that remains active. These signals describe different problems: dropped frames usually point towards the connection, while rendering or encoding strain points towards the computer or output workload.
Test the first full cycle when practical. Pay particular attention to:
- the transition from each file to the next;
- the final file returning to the first;
- files with different resolutions or frame rates;
- the first and last seconds of audio in every item;
- black frames, frozen images or unexpected title cards;
- the computer's power, sleep and automatic-update settings.
Keep a second copy of important media and a written record of the current playlist. If you change the order later, test the changed transition again. The troubleshooting guide for an OBS YouTube stream that keeps disconnecting is useful when the issue is a connection or encoder problem rather than a bad MP4.
Decide whether local OBS is the right workflow
OBS with VLC is a good fit when you want local control, scenes, overlays and direct access to the files. It is also a practical choice when you are comfortable leaving a computer on and checking it. The trade-off is that the complete chain remains your responsibility.
| Workflow | Choose it when | Main trade-off |
|---|---|---|
| OBS with VLC playlist on a local computer | You want flexible scenes, local files and hands-on control | The computer, files, power, network and OBS process must remain available |
| FFmpeg on a server | You are comfortable with command-line setup and server maintenance | You must manage restarts, monitoring and troubleshooting; loop boundaries can require timestamp testing |
| Managed cloud encoder | You want playback without leaving a home computer running | You must check the provider's current terms, workflow, limits and cost |
FFmpeg can be efficient for an operator who already maintains a server, but it is not automatically simpler. A loop that works in a command line may still produce a timestamp or transition problem at the boundary. Test the actual output instead of assuming that stream-copy looping will be seamless.
A managed cloud workflow moves the local computer dependency elsewhere, but it does not remove the need for preparation. You still need suitable media, a private stream key, a YouTube event and a way to check the result. For operators who do not want to leave a household computer running, StreamNeo removes the need to keep that local playback machine on by taking an uploaded video and running the YouTube feed from the cloud, with automatic monitoring and restart handling.
No workflow guarantees uninterrupted streaming. Local OBS depends on hardware and connectivity; a cloud service depends on the provider and your account; a server workflow depends on your maintenance. Choose according to which dependency you can actually monitor and recover from.
Rights, archives and ongoing checks
Only broadcast video and audio that you own or have permission to use. A file being available on your computer does not establish that you can retransmit it on YouTube. Keep licences, permissions and source records with the project, and check whether permission covers continuous public streaming, music, performances and territorial restrictions.
YouTube's monetisation features and eligibility are separate from the technical ability to loop MP4 files. YouTube says monetised livestreams can use features such as ads, Super Chat, Super Stickers and memberships, but ad delivery is not guaranteed, and a continuous loop does not by itself establish eligibility. Check the current official monetisation requirements for your channel before planning income around the stream.
YouTube's encoder documentation says streams under 12 hours are automatically archived. That does not justify promising that one uninterrupted 24/7 broadcast will produce a complete full-day replay. If a complete archive matters, plan separate recordings or segments and confirm the current archive behaviour in YouTube Studio.

FAQ
How do I loop multiple MP4 files on a 24/7 YouTube livestream?
Install VLC, open OBS, create a scene and add VLC Video as the source. Add the MP4 files in order, keep Shuffle Playlist off when sequence matters, enable Loop Playlist, then connect OBS to YouTube and verify the incoming feed in Live Control Room.
Is OBS Media Source the playlist feature?
No. OBS Media Source is suited to a single file and has its own loop control. For several sequential local files, use VLC Video, and install VLC first so the source is available.
Do I need to leave my computer running?
For the local OBS workflow, yes: the computer, files, power and internet connection need to remain available while OBS sends the feed. A managed cloud workflow can remove the need for a home computer to stay on, but you still need to check the provider's current terms and monitor the YouTube event.
Will YouTube save a complete archive of a 24/7 stream?
YouTube says streams under 12 hours are automatically archived, but that statement does not promise a complete archive for one continuous 24/7 stream. If a full replay matters, use planned segments or separate recording and check YouTube's current archive guidance.
