A spare PC can run a prerecorded YouTube Live channel by playing a local video or playlist through OBS. You prepare the media, connect OBS to YouTube Live, and leave the computer and network connection running while the broadcast is active.
This is a workable local setup, but it is not the only way to stream prerecorded videos 24/7. The important part is to test your own files, connection, power settings and overnight behaviour before treating the channel as dependable.
Choose between one video and a playlist
Start by deciding whether the channel needs one long file or a sequence of separate files. A single prepared video is simpler: OBS can play it as a Media Source and restart it when it reaches the end. This suits a devotional loop, an ambience recording, a local information reel or a lesson that should repeat in the same order.
A playlist gives you more variation. You can place several recordings in a folder and let OBS’s VLC Video source play them in sequence. OBS documents loop and shuffle controls for this source. It requires VLC to be installed, and OBS notes that 64-bit OBS requires 64-bit VLC.
The choice affects what you need to check. With one file, inspect the join between the final frame and the first frame. With a playlist, inspect every file boundary and confirm that the audio does not become silent or change volume unexpectedly. If your channel contains a set of recorded school lessons, for example, a playlist may be more useful than repeatedly showing one long lesson. You can also read how to make a 24/7 stream of recorded school lessons in India for considerations specific to that type of channel.
A local playlist does not automatically solve content rights or viewer expectations. Make sure you have the necessary rights for the video and audio, and tell viewers what the loop contains. If you are working with bhajans, check the music position separately from the technical setup. The guide on copyrighted bhajans in a 24/7 YouTube Live stream covers that question in more detail.
| Approach | What you prepare | Useful when | Main thing to test |
|---|---|---|---|
| One Media Source | One local video file | The same programme should repeat | The end-to-start transition |
| VLC Video source | Several local files and VLC | You want a sequence or shuffle | File order, transitions and audio |
| Cloud-based playback | Uploaded media and a cloud tool | You do not want a local PC running | The provider’s controls and YouTube connection |
The table is a planning aid, not a reliability ranking. None of these approaches removes the need to test the complete broadcast path.
Prepare the video before opening OBS
Keep the media in a stable local folder rather than a removable drive that may be unplugged. Use clear filenames and decide the order before you build the scene. For a playlist, names such as 01-opening.mp4, 02-main-programme.mp4 and 03-closing.mp4 make the intended order easier to verify.
OBS’s Media Sources documentation lists support for video types including MP4, TS, MOV, FLV, MKV, AVI, GIF and WebM. It also lists audio types including MP3, AAC, OGG and WAV. Support can still depend on the actual file and the OBS installation, so open each file in the target computer and confirm that both picture and sound work.
Do not wait until the live broadcast to discover that a file has a missing codec, an unexpected rotation or a silent audio track. Play the complete file in a normal media player, then test it inside OBS. A file that opens in one application is not enough evidence that it will behave correctly in your scene.
Review the visual layout at the size you intend to stream. If the source is a devotional video, check that text, subtitles and deity imagery are not cut off by the scene canvas. For a news loop, check that tickers and local-language captions remain readable. For a study channel, check that diagrams and small labels survive the final output size.
A long file is not necessarily easier than a playlist. It may simplify the OBS source, but replacing it means preparing the entire file again. Separate files make editing and reordering easier, while adding more places where a transition can go wrong. Choose the arrangement you can inspect and maintain.
You should also decide what happens when a file is unavailable. A playlist may skip or fail around a missing item, depending on the application and file state. Keep a copy of the source files in a known location, and do not rename or move them after the test unless you update the source settings.
Add and loop media in OBS
Install OBS Studio from the OBS Project and open it on the spare PC. Create a scene for the programme, then add the relevant source. For one video, choose a Media Source, select the local file and enable Loop. That setting tells OBS to start the file again when playback reaches its end.
Give the source a descriptive name instead of leaving several sources labelled “Media Source”. Names such as Main devotional file or Night ambience playlist make later checks less confusing. Confirm that the source is visible in the preview and that the audio meter moves when the file plays.
For a playlist, add a VLC Video source. Choose the files, set the order, and select the loop or shuffle behaviour that matches your programme. Install VLC separately if it is not already present. Check whether OBS is 64-bit before installing VLC, because OBS’s documentation states that 64-bit OBS requires 64-bit VLC for this source.
Keep the scene uncomplicated for the first test. A full-screen video source is easier to diagnose than a scene containing several browser sources, animated overlays and capture devices. You can add a logo or text later, after the basic video and audio path has worked for a sustained period.
Watch the source through at least one complete cycle before connecting YouTube. Look for a black frame, a frozen image, a sudden audio jump or a delay between picture and sound. With a playlist, note the exact order and test the transition from the last item back to the first if looping is enabled.
A local file can also be affected by the computer itself. Avoid moving the media folder, changing the account that opens OBS, or installing system updates immediately before an overnight test. The aim is not to assume that the PC is suitable; it is to observe what happens on that particular PC under the conditions you expect to use.
Connect OBS to YouTube Live
Enable YouTube Live before you need to start the channel. YouTube says first-time live-stream enablement can take up to 24 hours, so do not leave this step until the planned launch time. You can learn how to enable live streaming in YouTube Studio before preparing the final broadcast.
Open YouTube Live Control Room and create or schedule the broadcast. Use the stream setup information that YouTube provides, then configure OBS as the encoder. YouTube’s encoder setup guidance explains the current workflow and the information required by the encoder.
Treat the stream key as sensitive account access information. Paste it into the correct OBS field, but do not publish it in a tutorial screenshot, send it in a public chat or store it in a shared document. If you believe it has been exposed, use YouTube’s controls to replace or reset it rather than continuing with a key that others may have seen.
YouTube recommends RTMPS for streaming to YouTube Live. Its encoder guidance also lists constant bitrate encoding and a 2-second keyframe interval, with the interval not exceeding 4 seconds. Use the settings in the current YouTube guidance and match the output to the connection you have actually tested.
There is a difference between configuring OBS and starting the public broadcast. OBS may show that it is sending data while the YouTube control room is still processing the incoming feed. Check the preview and health indicators in YouTube Live Control Room before announcing the stream to viewers.
Do not change several settings at once when troubleshooting. First confirm that OBS sees the local source. Then confirm that OBS is connected. Then check that YouTube receives a picture and audio. A staged check makes it easier to identify whether the problem is the file, OBS, the network or YouTube’s ingest path.
Use a wired connection where practical
A wired Ethernet connection removes one variable between the spare PC and the router or switch. OBS recommends wired networking for streaming because Wi-Fi may be unstable. That is a recommendation, not a claim that every wireless connection will fail. If the PC must use Wi-Fi, test it in the same location and at the same time of day in which you plan to stream.
Place the PC where it can remain connected without someone accidentally moving the cable or switching off the power strip. If the router is in another room, consider whether a reliable wired route is practical. The right arrangement depends on the building, equipment and network layout; do not buy a new computer or cable merely because a general checklist says you must.
Your internet connection has two relevant sides. The local network must carry the encoded stream from OBS to the router, and the internet connection must upload that stream to YouTube. Other devices using the same connection can change the conditions. A family member uploading a large file, a security camera sending footage or a software update can affect the test.
If you see dropped frames or a disconnection, check the network stability, the configured bitrate, device drivers and the route to the ingest server. OBS’s stream connection troubleshooting guidance provides a starting point for that investigation.
Avoid treating a brief successful preview as proof of an overnight connection. A local PC may stream correctly for a short session and still encounter a router reset, a power interruption or a network change later. Your test should be long enough to expose the conditions that matter to your channel, without assuming that any particular duration guarantees uninterrupted operation.
Test upload and stream health
Run an upload speed test from the same internet connection before choosing output settings. The result is only a snapshot, so repeat it at a busy time if your household or business connection changes during the day. Choose a quality and bitrate that leave room for normal variation rather than using the most demanding setting the connection briefly reports.
Start OBS and watch its statistics while YouTube receives the feed. Look for dropped frames, rendering or encoding warnings, and an audio meter that behaves as expected. On YouTube, inspect the stream preview and health messages in Live Control Room. These two views show different parts of the route, so check both.
Test the actual content, not a blank scene. Let a file play through a transition, or let the playlist move between several items. Check the stream from a separate device or connection so you can see what a viewer receives. Listen for audio that is too quiet, missing, delayed or abruptly reset at a loop point.
A useful test record includes the date and time, the OBS output settings, whether the connection was wired or wireless, and what happened at each transition. Write down any dropped frames or disconnections instead of relying on memory. If the test fails, change one relevant item and repeat it.
Test the boring parts as well. Confirm that the computer does not enter sleep during playback, that the display turning off does not stop OBS, and that the source remains available after a normal restart. Operating-system power controls differ, so use the settings for your own system and verify them rather than assuming a general instruction applies.
Also consider what you will do after a power cut or application crash. A spare PC does not automatically reopen OBS, restore the correct scene or reconnect to YouTube. You may be able to configure those behaviours on your operating system and applications, but they are specific to your setup and should be tested before you depend on them.
Keep an eye on the PC during the sustained test. Check for heat, unexpected restarts, storage warnings and changes caused by updates. This does not establish a universal hardware requirement, and it does not promise that the machine will run indefinitely. It tells you what your own machine does under the workload you have chosen.
If the stream stops overnight, the failure may not be in the video. Compare OBS’s log and statistics with YouTube’s stream health information, then check the network and power history. The 3am failure checklist can help organise that review.
Decide whether the PC should stay on
The local workflow gives you direct access to the files, OBS scenes and connection. It can be useful when you want to change the playlist yourself, keep media on a local drive or avoid uploading a large library to another service. It also means the computer, power supply, operating system and local internet connection remain part of the broadcast.
That ongoing responsibility is the central trade-off. Someone needs to check the stream, respond to a failed source, install important updates at a sensible time and investigate interruptions. A spare PC may already be available, but availability is not the same as suitability. Only a sustained test can show whether the particular machine and network behave acceptably.
YouTube’s own encoder guidance describes cloud-based tools for 24/7 prerecorded streaming. A cloud workflow moves the playback task away from your room and removes the need to keep this PC sending the stream, but it introduces another service, another set of controls and another account or upload process to understand. You should review the provider’s current terms, supported formats, retention rules and monitoring features directly.
If the main problem is leaving a computer running, StreamNeo removes that specific task by letting you upload the video, provide the YouTube stream key and have the prerecorded broadcast run from the cloud, with monitoring and automatic restart if the stream drops. It is YouTube-only, so it should be considered for that use case rather than treated as a general multichannel streaming tool.
The local approach may be better when you need frequent hands-on changes or want the files to remain on your own computer. A cloud approach may be better when keeping a PC powered and connected is the part you cannot manage. Neither choice guarantees uninterrupted operation, and you should test the complete path before telling viewers that the channel is always available.

FAQ
Can I loop one video on YouTube Live with OBS?
Yes. Add the local file as an OBS Media Source and enable its Loop option. Test the end-to-start transition and the audio before connecting the broadcast to YouTube.
Is VLC required for an OBS playlist?
VLC is required for OBS’s VLC Video source. That source can handle multiple files and offers loop and shuffle controls; OBS notes that 64-bit OBS requires 64-bit VLC.
Does a spare PC need a particular specification?
There is no universal specification established by this workflow. Your result depends on the files, output settings, OBS scene, operating system and network, so test the actual computer rather than assuming it is suitable.
Is Wi-Fi impossible for 24/7 streaming?
No. Wi-Fi may work in a particular environment, but OBS recommends a wired connection because wireless conditions can be unstable. If you use Wi-Fi, test the stream from the intended PC location and monitor for dropped frames or disconnections.
