OBS is usually the more approachable choice when you want to build a scene, add overlays and see the stream controls while a prerecorded video loops. FFmpeg may suit you better if you are comfortable with command-line automation, but this research did not verify current loop flags or a tested command, so do not copy an unverified recipe into a long-running broadcast.
Neither tool makes a stream failure-proof. Both still need a YouTube Live setup, a tested encoder output and a plan for monitoring, recovery and any local recording you need.
Choose by the work you need to do
Start with the task around the video, not the name of the encoder. If the broadcast includes a logo, a title card, a clock, a camera feed or a changeable set of scenes, OBS presents those parts as sources in a graphical interface. You can inspect the composition and operate it with visible controls. Its official Media Sources guide documents adding media to a scene and enabling Loop so the source restarts after playback ends.
FFmpeg is a command-line-oriented option. That can be useful if you want to launch a process from a script or fit the encoding step into an existing automated workflow. The trade-off is that you must be able to check and maintain the command-line setup. In particular, do not assume that an example found in an old post uses current syntax or will behave correctly with your file and YouTube settings.
| What matters to you | OBS | FFmpeg |
|---|---|---|
| Seeing and arranging the output | Graphical scene and source workflow | Command-line-oriented workflow; composition depends on the pipeline you build |
| Looping evidence in this research | OBS Media Source has a documented Loop setting | Exact current loop flags and a tested command were not verified here |
| Automated launch | Possible to operate within a broader process, but plan supervision separately | May fit scripted launch and automation if you can validate and maintain it |
| Live operator changes | Visible controls are suited to a person managing scenes and sources | Less suited to visual scene management without additional tooling |
| YouTube ingest and review | Must be configured and tested against YouTube guidance | Must be configured and tested against the same YouTube guidance |
This is a workflow comparison, not a claim that one encoder is more reliable. OBS can be the clearer choice for a devotional channel that wants a persistent title and occasional scene changes; a fixed video output managed by someone comfortable with scripts may be a reasonable FFmpeg use case. If your principal concern is whether a local computer must stay switched on, the choice of encoder does not answer that by itself. Consider the separate operating trade-offs discussed in spare PC or cloud streaming for Indian creators.
Where OBS fits: scenes and visible controls
In OBS, you assemble the picture as a scene from sources. A Media Source can play a local media file; other sources can provide elements such as a logo or text. This model is useful when the broadcast is not simply a video filling the whole frame. You can see the assembled scene in the preview, choose which scene is active and make a change without editing a command line.
For a straightforward loop, add the prerecorded file as a Media Source and enable its Loop setting. OBS documents that the source starts again when the media finishes. That is a specific, useful behaviour, but it is not a complete 24/7 operating plan. A loop setting does not establish that the application will recover from every failure, that the computer will stay awake, or that a network interruption will be repaired without intervention.
The visual approach also makes a preview check more tangible. You can check that the video fills the intended area, that text does not cover an important part of the picture and that audio is present. If you use several scenes, inspect transitions as well as the opening scene. The practical cost is that somebody needs to understand the OBS project, keep the source file available and recognise when the displayed preview or stream status needs attention.
Choose OBS if the visible composition and manual control are valuable enough to justify keeping an operator or a carefully maintained local setup in the plan. It is not a reason to leave an untested session running overnight and hope the controls will take care of every eventuality. For a channel built around children’s stories, the same scene-and-source pattern is explored in making a 24/7 kids’ story channel with OBS; the operational questions still need to be tested for your own file and connection.
Where FFmpeg may fit: command-line automation
FFmpeg may make sense when your output is fixed and you are comfortable managing a command-line process. A script can be part of a repeatable workflow, and a technical operator may prefer to configure and launch that process without arranging a graphical scene. That is a potential workflow advantage, not evidence that a particular command will loop a file correctly or survive an overnight run.
The distinction matters because the loop is only one part of the job. The file’s video and audio streams, the selected output codecs, the connection to YouTube and the handling of a process exit all affect whether the broadcast continues as intended. A command that starts successfully during a short test is not proof that it will behave the same way after a disconnection, an application update or a host restart.
If you already maintain an FFmpeg-based broadcast, keep the launch process, its logs and its recovery plan understandable to whoever will be on call. Decide how you will notice that the process has stopped or YouTube has stopped receiving a healthy feed. A restart mechanism is a separate operational decision, not something established merely by selecting FFmpeg. For discussion of reconnect behaviour in a related use case, see reconnecting an FFmpeg podcast stream, but do not treat that as verification of a loop command for this setup.
If you do not already work comfortably with command-line media tools, the apparent simplicity of a copied command can hide more troubleshooting than a graphical workflow. Pick FFmpeg for the control and automation you can actually support, not because “command line” implies unattended reliability.
What OBS documents about looping
The verified OBS behaviour is narrow and clear: add a Media Source to a scene and turn on Loop; when the media ends, the source starts again. That lets you build a repeating presentation without manually pressing play at the end of every pass. It does not mean that YouTube sees a single uninterrupted programme forever, nor does it certify that OBS, the computer or the connection will never fail.
Check the source itself before relying on that setting. Play it through locally, including the end and beginning, and listen for an abrupt silence or an unwanted pause at the join. A file can loop exactly as instructed and still have a noticeable seam because its final image or sound does not lead naturally into its opening. If the content contains several clips, decide whether they belong in one prepared video or in a more involved scene workflow; do not assume a source loop will arrange a playlist in the order you intend.
For music or devotional material, file access and rights are separate questions from playback. A song being available online does not by itself grant the right to rebroadcast it. YouTube’s live-stream terms place responsibility for necessary rights, including applicable music licensing, on the provider. Review the current YouTube live-stream terms and your own permissions; the practical considerations are also covered in music licensing for a monetised 24/7 channel. Do not treat a working loop as evidence that the content is cleared for your channel.
Why an unverified FFmpeg command is not enough
This comparison does not verify the current official FFmpeg documentation for exact looping flags, and it does not include a tested command. That is why there is no universal command here. Media commands depend on the input and intended output, and an example that appears plausible is not a substitute for confirming the current documentation and testing the actual file.
A robust test would need to establish more than whether a process starts. You would need to confirm that the file repeats at the intended boundary, audio remains in sync, the outgoing stream uses settings YouTube accepts, and the process behaves as expected if the connection drops. You would also need a way to notice a failure and decide whether the process should restart. None of those outcomes can be inferred from a flag name alone.
If FFmpeg is your preferred tool, consult its current official documentation for the version you intend to use and validate a command with a short, representative test before relying on it. Make the test observable: inspect the YouTube preview, listen to the stream and review stream health messages. For the general YouTube encoder workflow, follow the current YouTube Live encoder guidance, rather than treating an old command snippet as a platform specification.
The same caution applies to OBS. Its documented loop is useful, but it does not guarantee recovery from power loss, operating-system updates, a network failure or an application crash. For either route, write down who receives an alert, what that person checks first and how the broadcast is returned to service. A long-running channel is an operating routine as well as an encoder choice.
Configure either encoder for YouTube Live
The YouTube side is shared whichever tool sends the video. In Live Control Room, create or configure the stream and copy its server URL and stream key into the encoder. YouTube’s stream setup guide describes starting the encoder, waiting for the preview and using the Go live action when the workflow requires it. Keep the stream key private: anyone who can use it may be able to send video to your channel’s live endpoint.
Use YouTube’s current encoder guidance for the output rather than assuming that an OBS preset or a remembered FFmpeg option is automatically suitable. YouTube recommends RTMP or RTMPS for the listed encoder workflow. Its guidance identifies H.264, H.265/HEVC and AV1 video codecs, allows frame rates up to 60 fps, recommends a two-second keyframe interval and says not to exceed four seconds. It also lists CBR bitrate encoding and bitrate ranges by codec, resolution and frame rate. Those details belong together: look up the current range for your chosen output on YouTube’s page instead of applying one bitrate to every resolution and frame rate.
For a simple loop, do not choose a higher resolution or frame rate merely because the source offers it. Decide what viewers need to see, what your connection can consistently send and what YouTube currently recommends for that combination. Then configure the encoder to match and check the preview. If the channel depends on a steady soundtrack, confirm that the selected audio is present and at an appropriate level; a live preview picture alone does not prove that viewers can hear the programme.
The key is the credential linking your encoder to the stream. Store it where the person responsible for the broadcast can retrieve it without putting it in public notes, screenshots or an exposed script. If you are testing privately, use the controls and workflow YouTube currently offers for the channel rather than broadcasting a test to an audience by accident. The private meditation test-stream guide covers that kind of check in a specific context.
Preview, playback and operating checks
A preview is a checkpoint, not a ceremony to click past. YouTube recommends testing with audio and movement representative of the broadcast, monitoring stream health and reviewing messages. A static title card does not test a moving video; a silent preview does not test the soundtrack. Use a representative portion of the actual programme and look for warnings before you take the stream public.
A useful test covers the beginning, a point well into playback and the transition where the loop returns to its opening. Check the picture for cropping or black frames, listen for a gap or a sudden volume change, and verify that the return to the beginning is acceptable to a viewer. Watch the stream from another device if practical, since the encoder’s local preview is not identical to the experience of a viewer receiving YouTube’s stream.
For an always-on plan, include what happens after the test. Decide how you will monitor stream health, who will see an alert, and what happens if the encoder stops or the connection is interrupted. If you depend on a local computer, account for power, sleep settings, updates and access to the source file. If the routine needs another person to intervene, make that responsibility explicit. Neither OBS nor FFmpeg alone answers these operational questions.
Think separately about the recording you may need later. YouTube says streams under 12 hours can be automatically archived, while streams longer than 12 hours may not be captured at all; it recommends keeping a local recording backup. A continuous 24/7 broadcast therefore should not be your only plan for preserving a complete copy. If a full archive matters, make and verify a local recording or plan deliberate shorter broadcast segments, and check YouTube’s current archive guidance before deciding what viewers will be able to replay.
Finally, consider how the content is presented, not only whether it repeats. YouTube’s monetisation policy applies to live streams and expects original, authentic content; repetitive or mass-produced material may be ineligible. A loop does not determine eligibility by itself, and continuous availability is not a promise of earnings. Review the current policy and make sure you have the rights to the material you send.
If keeping a computer running and recovering a local encoder would be the part of the plan most likely to fail, StreamNeo removes that specific burden by letting you upload the video once and run the YouTube broadcast with your own computer switched off; you still need to prepare the file, check the stream and handle your content and channel responsibilities.

FAQ
Is OBS or FFmpeg better for a prerecorded YouTube loop?
OBS is generally the easier fit if you want scenes, overlays and visible controls; its Media Source has a documented Loop setting. FFmpeg may suit a command-line workflow, but this article does not verify exact current loop flags or a tested command. Choose based on the workflow you can test and maintain.
Does OBS Loop guarantee a 24/7 stream?
No. The setting restarts the media source after the file ends, but it does not guarantee that the application, computer, network or YouTube ingest will stay available. Plan monitoring and recovery separately.
What should I test before going live?
Send a representative test with moving video and audio, inspect the YouTube preview, check stream health and review any messages. Listen and watch through the point where the video returns to its beginning, and confirm that the output is acceptable from a viewer’s device.
Will YouTube keep a complete archive of a continuous 24/7 stream?
Do not rely on that. YouTube says a stream longer than 12 hours may not be captured as an archive and recommends a local recording backup. If a complete copy matters, arrange and verify one separately.
