OBS and FFmpeg can both send a prerecorded video feed to YouTube Live, but they suit different working styles. Choose OBS if you want to build scenes and manage playback through a graphical interface; choose FFmpeg if you are comfortable configuring a command-line process and supervising it.
Neither choice guarantees an uninterrupted broadcast. For a 24/7 channel, the practical decision is about how you prepare the media, control repetition, notice a problem and recover, as well as how you configure YouTube’s ingest settings.
Define the nonstop-stream workflow
A nonstop prerecorded stream is not simply a video uploaded to YouTube. An encoder reads a local media file or playlist, packages its video and audio as a live feed, and sends that feed to YouTube Live using the stream URL and key from Live Control Room. YouTube receives it as a broadcast, even though the pictures were recorded earlier.
That distinction matters when planning the channel. Your playback tool is responsible for supplying a feed; YouTube is responsible for receiving and distributing it. The file needs to play as intended, the encoder needs to remain configured, and someone needs a way to check the live preview and stream health. A failure in any part of that chain can affect what viewers see.
Before choosing software, answer four questions. Will you repeat one file or rotate several? Do you need titles, overlays, scene changes or other visual elements? Can you configure and supervise a command-line process? Who will check the broadcast and respond if the feed stops or becomes silent?
If you are comparing the broader shape of a continuous channel rather than only its encoder, the guide to building a FAST-style linear channel from your video library can help clarify how a catalogue becomes a scheduled viewing experience. Keep rights and channel-policy questions separate from the software decision: an encoder does not establish that you have permission to broadcast every item or that a particular format is eligible for monetisation.
Use OBS for graphical playback
OBS Studio offers a graphical way to assemble a broadcast from sources and scenes. For a single local video, add a Media Source and enable its Loop option. That suits a simple devotional channel, a study ambience stream or a business information loop when the main job is to keep one prepared clip playing.
OBS becomes more useful when the feed needs visual composition as well as playback. You can arrange sources in a scene and manage them in the same interface, rather than encoding every visual element into the source file first. This can make it easier to see how an overlay or background sits on the picture before starting the live feed. It does not remove the need to check the actual YouTube preview.
A graphical interface is not a substitute for an operating plan. The computer running OBS must remain on, the source media must remain available, and a person or monitoring arrangement must notice problems. If the computer restarts, the network changes or the application stops, the workflow still needs a way to resume the broadcast. Treat those as operational questions, not as evidence that OBS is inherently less or more reliable than another encoder.
For basic setup context, the YouTube live-stream equipment guide is relevant even if your source is prerecorded. You do not need to buy equipment merely because you are comparing OBS and FFmpeg; first check whether the computer and connection you already have can handle your chosen configuration during a representative test.
Set up an OBS playlist
For a sequence of prerecorded clips, OBS’s VLC Video source provides playlist controls, including loop and shuffle. VLC must be installed separately. The OBS documentation notes that a 64-bit installation of VLC is needed when using 64-bit OBS, so check that the application and VLC installation match before diagnosing a missing or unavailable source.
Build the playlist deliberately. Check that every item opens, that the order is the one you expect, and that the audio level is reasonably consistent from one clip to the next. If you choose shuffle, decide whether the resulting order is acceptable for the channel. A bhajan stream may need a deliberate progression; an ambience station may be less sensitive to order, but still needs a playlist that does not break when it reaches a particular file.
Run the playlist long enough to observe a transition, rather than only checking the first clip. Confirm that the outgoing item ends as expected, the next item begins, and the live preview continues to show and hear the intended material. Include any overlays or scene changes that will be present during the actual broadcast. A playlist that looks correct in a settings panel can still have an unsuitable transition or a mismatched audio level in the viewer-facing output.
The OBS source and playlist options are described in the OBS Media Sources documentation. Interface details can change between releases, so use that page alongside the version of OBS installed on your computer. If your main need is a playlist rather than a scene-based production, it is worth testing this path before investing time in a scripted alternative.
Use FFmpeg for command-line looping
FFmpeg is suited to operators who are comfortable specifying input, output and encoding choices in a command. A looped input can be paced in real time and sent to a YouTube ingest endpoint. One documented pattern uses -re with -stream_loop -1 to read a file at its playback rate and repeat it. The exact command depends on the media and output configuration; a command copied without understanding its inputs and codecs can fail or produce an unsuitable feed.
A third-party guide describes a workflow that copies prepared video while re-encoding audio. Treat it as an example to examine, not as an official YouTube recipe or a guarantee of seamless playback. Copying video is only appropriate when the source stream’s properties are compatible with the intended output. If you change the command, check both the video and audio paths rather than assuming a working file will be accepted unchanged.
FFmpeg’s strength here is that the playback and sending process can be expressed in a repeatable configuration. That can suit a small channel whose operator already manages scripts and knows how to inspect a running process. It can also make troubleshooting less accessible to someone who is not used to command-line errors. A typo, an incorrect file path or an unsuitable output parameter may be harder to spot than a source that is visibly missing in a graphical scene editor.
A single-file loop is a different task from managing a programmed schedule. FFmpeg can be scripted, but playlist behaviour depends on how the command and surrounding process are constructed. Decide how files will advance, what should happen at the end of a clip, and how you will make a safe change to the running configuration. If you want to understand other channel-specific approaches to prerecorded playback, the article on running an always-on stream of gaming reviews and walkthrough videos offers a useful adjacent example, not a substitute for validating your own command.
Compare automation and monitoring needs
The difference is not a proven reliability ranking. The reviewed material does not establish that either encoder is inherently more reliable, and it does not provide a controlled comparison of uptime or general CPU use. Instead, compare the amount of hands-on configuration each workflow requires and the tools you already know how to supervise.
| Need | OBS Studio | FFmpeg |
|---|---|---|
| Configure playback | Add a source and use graphical controls | Set input and looping options in a command |
| Repeat one file | Enable Loop on a Media Source | Use a looped input, such as -stream_loop -1, with suitable pacing |
| Arrange visuals | Compose scenes and sources in the interface | Prepare the visual stream or construct a more involved command workflow |
| Manage a playlist | VLC Video source can play a playlist, loop it and shuffle it; VLC is required | Possible through scripting, but the playlist behaviour depends on the command and process design |
| Best fit | You prefer visible source controls and scene composition | You can configure, inspect and supervise a command-line process |
For either method, decide how an operator will notice a stopped feed, a black picture, missing audio or a stream-health warning. YouTube’s own advice is to test before starting a live stream, check the preview and monitor audio and video quality. That means your process should include a named person or a practical routine for looking at the broadcast, especially when the channel runs unattended overnight.
Process supervision is also separate from the encoder. A command-line operator may already have a way to restart a stopped process; an OBS operator may have a familiar desktop routine. In both cases, specify what counts as a problem, how the person on duty will confirm it, and what action they can take. Do not assume a restart automatically restores the intended scene, playlist position or sound. Test recovery, rather than treating an automatic restart as proof of continuity.
If your main constraint is that no local computer can remain switched on or be watched, a hosted playback workflow may remove that particular burden. StreamNeo is designed for uploading a video and sending it to YouTube without keeping your own computer on, which can be relevant when supervising a local process is the obstacle. It remains a YouTube-only route, and you still need to prepare suitable content, configure the channel and check the output; it is not a promise that a stream cannot drop.
Configure YouTube ingest
The shared YouTube setup is broadly the same whichever encoder you select. Create or schedule the live event in YouTube Studio, then retrieve the stream URL and key from Live Control Room. Enter them in the chosen encoder’s streaming settings. YouTube explains that the key identifies where it should receive the feed and allows it to accept the stream, so handle it like a password. If it is exposed, reset it rather than leaving a compromised credential in use.
YouTube recommends RTMPS, an encrypted extension of RTMP. Use it where your chosen encoder supports it, and copy the current ingest address from YouTube rather than relying on an old saved configuration. The YouTube encoder setup guidance covers stream-key setup and encoder connection. Refer to the live page for current values, because YouTube’s ingest recommendations can change.
Match the output to the resolution, frame rate, codec and bitrate you intend to send. YouTube’s current encoder guidance lists RTMP or RTMPS ingest and supports H.264, H.265 and AV1, up to 60 frames per second. It recommends constant bitrate and a two-second keyframe interval, which should not exceed four seconds. These are technical recommendations to check against the live documentation, not a reason to select the highest available resolution by default.
Choose bitrate from YouTube’s current table for the resolution, frame rate and codec, rather than copying a value from a different setup. A stable, correctly configured picture at a suitable resolution is more useful than a nominally higher setting that your connection cannot sustain. The page on fixing a YouTube Live resolution mismatch is useful if the incoming output is rejected because its resolution settings do not agree.
Confirm the audio format and levels as well as the picture. A quiet or absent audio track can be missed if you only inspect a still frame, while a high level can become unpleasant when a playlist changes clips. YouTube’s setup page is the authority for its currently supported ingest settings; the encoder interface is where you apply them.
Test the live output
YouTube Help says, “Make sure to test before you start your live stream.” Follow that advice with a test that resembles the real broadcast. Use the intended file or playlist, the intended output settings, and representative movement and sound. Check the preview in Live Control Room and inspect stream health before relying on the feed for viewers.
Test transitions and repeat behaviour, not only the opening seconds. For a single file, confirm that it reaches the end and begins again as expected. For an OBS playlist, observe a change between items and verify the next item’s audio. For FFmpeg, verify that the loop continues and that the process is still sending the intended output. These checks show whether the selected workflow behaves as configured; they do not establish that a later broadcast will never fail.
Make a simple response plan. Record where the stream key is stored, who can access Live Control Room, who checks the stream, and how that person will restart or correct the encoder if needed. Keep credentials out of public scripts or screenshots. If an operator changes the source file, playlist or command, repeat the relevant test before treating the revised setup as ready.
Set archive expectations conservatively. YouTube says streams under 12 hours are automatically archived. The cited setup guidance does not promise that one indefinitely running stream will produce a complete archive after crossing that duration, so do not rely on a single continuous broadcast as your only copy of the source material. Keep the original files and check YouTube’s current archive guidance for your planned format.
A prerecorded stream also remains subject to the rights and policies that apply to the content and channel. Looping a file does not settle copyright or monetisation questions. Review YouTube’s current rules and make sure you have the necessary rights for the music, video and other material you broadcast. For practical context, see the guide to avoiding copyright claims when looping videos on YouTube Live; it is guidance, not a substitute for checking your own rights and the current official policies.

FAQ
Can OBS loop a video on YouTube Live?
Yes. Add the local file as an OBS Media Source and enable its Loop option, then send the OBS output to the YouTube event. Test the end-to-start transition and check the live preview and audio before relying on the setup.
How do I stream a prerecorded video 24/7 with FFmpeg?
Configure FFmpeg to read the file in real time, loop it, and send the output to YouTube’s current ingest URL with the stream key. A commonly documented pattern uses -re and -stream_loop -1, but the full command must suit your media and YouTube’s current ingest requirements. Test the output and arrange a way to monitor the process.
Which is more reliable for a nonstop stream?
There is no substantiated comparison here that makes OBS or FFmpeg inherently more reliable. Reliability in practice depends on the whole setup, including the source media, computer, connection, configuration and how quickly someone notices a problem. Choose the workflow you can operate and monitor, then test recovery as well as playback.
Can I expect a complete YouTube archive from a stream that runs indefinitely?
Do not assume so. YouTube says streams under 12 hours are automatically archived, but the cited guidance does not settle whether one continuous stream beyond that duration will have a complete archive. Keep your original media and consult YouTube’s current help pages for the latest guidance.
