If you want to relay prerecorded video to YouTube around the clock, FFmpeg, OBS Studio and Stream247 address different parts of the job. FFmpeg is a command-line building block, OBS is a graphical encoder and scene tool, and Stream247 describes a dashboard-led headless relay; the available documentation does not establish a tested winner for reliability or performance.
The practical choice is the workflow you can configure and monitor: how your media is selected and looped, where the process runs, and what you will do when a file, connection or host needs attention. A 24/7 stream also depends on YouTube ingest settings and an always-available host, not just the application you choose.
What a prerecorded 24/7 relay needs
A relay takes prepared media, encodes or packages it as required, and sends a continuous live broadcast to YouTube. In Live Control Room, you create or select a stream and give the encoder the stream URL and stream key. You then start sending content and check the preview and live state. YouTube’s encoder setup guidance describes that sequence.
There are three separate jobs to plan for. First, decide what is playing: one looping file, a folder of files, or a playlist. Second, decide how the video reaches YouTube: for example, an FFmpeg command, an OBS output, or a relay interface. Third, keep that process and its host available and notice when something stops working. An encoder can be configured correctly and still fail to continue if the computer sleeps or its network drops.
Think through what should happen between items and after a failure. A single devotional recording that repeats has a simpler selection problem than a station that needs songs in a planned order. A local news loop may need an operator to replace an outdated item. Before choosing a tool, write down whether you need shuffling, scheduled changes, a visible preview, or only a fixed media sequence.
The media itself matters too. Video and audio files can differ in codecs, frame rates, resolution, and audio sample rate. If a tool has to convert them while streaming, the host must do that work in real time; the sources here do not establish a minimum computer specification. If you want a worked example of channel planning, see creating a 24/7 language-learning live stream.
FFmpeg: a headless building block
FFmpeg is suited to a headless workflow: you configure it with commands rather than operating a graphical scene editor. A community deployment example documents looping local video and audio files and sending an RTMP stream from an Ubuntu VPS. It also uses a systemd service with restart behaviour. That makes it a useful reference for understanding how a script and a service manager can fit together, not proof that a particular configuration will suit every file or host.
This approach gives you control over the command, input list and output settings, but it expects you to understand and maintain them. You need to know where media is stored, how the sequence is constructed, what happens if an input is missing, and how the process is restarted. A systemd restart rule can relaunch a process after it exits; it cannot by itself tell you that the picture is wrong, that the network is persistently unavailable, or that the stream is not in the state you intended. Monitoring remains a separate task.
File consistency is another consideration. A set of mixed files may not share the same characteristics, and the relay may need to convert them into a consistent output. That can add configuration and encoding work. The cited community example does not establish universal input compatibility or prescribe hardware sizing, so test your actual files and observe the host rather than assuming a recipe transfers unchanged.
A command-line workflow can make sense if you are comfortable editing configuration, using a Linux host and checking logs. If you are not, the low cost of starting with an open-source tool can be offset by the time required to diagnose it at night. For a more specific Linux example, compare the considerations in the FFmpeg and MediaMTX bhajan setup; it addresses a related workflow, not a universal requirement for a relay.
Keep the YouTube stream key private. Treat it like a password: do not place it in a public repository or share configuration files that expose it. The cited community deployment example specifically warns against publishing the key. If you store commands or scripts in version control, use a method that keeps credentials out of the files people can see.
OBS Studio: a graphical encoder and scene workflow
OBS Studio is the better fit to examine when you want to compose a visible production rather than simply relay a playlist. Its graphical interface lets you work with scenes and sources, so you can arrange a still image, overlays, or other elements alongside media. This is useful if the channel presentation changes on screen or you want to inspect the output while setting it up. The OBS Project identifies OBS as open-source software under GPLv2 and free for commercial use; its official help pages cover streaming and connection issues.
A graphical interface does not remove the need for a host that stays on. OBS must remain open and streaming on the computer or hosted desktop where it is running. You need to account for that machine’s availability, network connection and encoding load. OBS’s help discusses bitrate-related dropped frames; a visible interface can help you inspect the stream, but it does not guarantee a stable connection or remove the need to respond to problems.
For a prerecorded channel, consider how the media should repeat and whether you need production controls in addition to playback. A fixed ambience video with a logo may fit a simple scene. A radio-style channel with changing album art or programme segments may need more deliberate source and scene management. The relevant question is not whether OBS can be made to send a live stream; it is whether its production interface is useful enough to justify keeping it running and maintaining the scene.
If you are assembling a radio-style output from several elements, the RadioDJ and OBS workflow offers a related point of comparison. Do not assume that a configuration intended for a desktop production workflow will behave like a headless service: the interface, session and host all remain part of the operating plan.
Stream247: a dashboard and playlist controls
Stream247’s repository describes a headless relay with a web dashboard. It says the tool can loop a YouTube playlist or video, accept direct HLS URLs, and send to RTMP or RTMPS destinations including YouTube Live. The repository also lists controls for resolution, frame rate, bitrate, encoder and shuffle. These are project claims in documentation, not independently verified tests of how the tool performs under your conditions.
The dashboard makes this a different proposition from writing an FFmpeg command directly. It may suit someone who wants a purpose-built control surface for a relay without using a full graphical scene workflow. Its listed inputs and controls also make it worth considering where your source already exists as a YouTube playlist or an HLS URL, rather than as local files that you intend to organise in a folder.
Before adopting it, check the project’s current documentation, maintenance activity, installation steps and how its input model matches your media. “Dashboard” describes an interface, not a guarantee that every failure will be detected or corrected. Confirm what you can see and control, what happens when the host or network goes away, and what manual recovery remains yours to perform. The available project description does not provide controlled reliability or performance results.
A dashboard can reduce the friction of changing listed settings, but it does not make YouTube’s ingest requirements disappear. You still need the correct destination and key, an available host, compatible media and a way to check the outgoing broadcast. If you need elaborate graphics or several live production sources, OBS’s scene workflow may be a closer fit. If you prefer direct command configuration, FFmpeg may be more transparent to you.
Compare inputs, looping, recovery and hosting
The options are easier to compare by workflow than by a blanket label such as “best”. The table reflects roles and capabilities documented in the cited material; it is not a benchmark, feature audit or recommendation that any one will run without intervention.
| Tool | Documented workflow and inputs | Looping or controls described | What you still need to plan |
|---|---|---|---|
| FFmpeg | Headless command-line workflow; a community example uses local video and audio files and RTMP output. | The example loops media and uses systemd restart behaviour. | Command configuration, file consistency, service monitoring, a host and recovery checks. |
| OBS Studio | Graphical encoder and scene workflow. | The official help covers streaming setup and bitrate-related dropped frames; the cited material does not establish a playlist-relay feature comparison. | Keeping the application and session running, scene/source setup, host availability and connection monitoring. |
| Stream247 | Repository describes a headless relay with a dashboard, YouTube playlist or video, and direct HLS URL inputs. | Repository lists looping, shuffle, resolution, frame-rate, bitrate and encoder controls. | Checking project maturity, input fit, host availability, and what its dashboard does or does not report during failure. |
Input is often the deciding difference. If all your material is on disk and you are comfortable maintaining a command, FFmpeg’s example is directly relevant. If your output is a composed scene and a person will manage it through a graphical session, OBS’s role is clearer. If the desired source and controls match the Stream247 repository description, investigate whether its dashboard offers the controls you actually need.
Looping should be tested with the exact sequence you intend to use. Confirm that the last item transitions to the first, audio behaves as expected, and a missing or changed file does not leave the output in an unwanted state. A loop setting is not the same as a content schedule: if you need different programmes at set times, establish whether your chosen tool supports that exact arrangement or whether you need to prepare and manage separate inputs.
Recovery has layers. An application may restart after a process exit; the host may reboot or lose connectivity; YouTube may report an ingest or configuration problem. A service manager such as systemd addresses one layer in the documented FFmpeg example, not every failure mode. You should decide how you will learn about a stopped stream and who will respond. If you want to run from a small dedicated computer rather than a VPS, streaming from a spare PC is relevant to the always-on host question, but the cited sources do not verify a specific computer’s capacity.
Hosting choices trade hands-on responsibility against dependence on a provider and a network connection. A home computer gives you direct access to local files, but it must stay powered, awake and connected. A VPS can keep a command-line process separate from your everyday desktop, as in the cited example, but you still manage its configuration and resources. Do not select hardware or a hosting plan from an invented minimum: the actual encoding load depends on the media and output settings, and no cited evidence quantifies a universal requirement.
YouTube ingest and audio/video requirements
Whatever tool you select, YouTube must receive a stream using the destination URL and key for the stream you selected in Live Control Room. Start the encoder, then check YouTube’s preview and live status rather than treating a running application as proof that viewers can see the intended output. The official encoder workflow is the place to check current setup instructions.
The YouTube Live Streaming API documents RTMP, RTMPS and HLS ingestion. Its stream health information can report states and configuration issues, including unsupported codecs and bitrate or sample-rate problems. The API documentation can help explain what health information is available, but it does not monitor your computer or replace checking the encoder and host. Match the output to the current instructions for your selected ingest path, and investigate a health warning instead of assuming a restart will cure it.
HLS has additional, specific constraints. YouTube’s HLS ingest guidance says HLS has higher latency than RTMP because it sends video in segments rather than as a continuous stream. It specifies TS segments of 1–4 seconds, rolling playlists with no more than five outstanding segments, HTTPS POST/PUT, and no encryption beyond HTTPS. These are requirements for the HLS path, not settings to apply to a typical RTMP setup.
Audio deserves its own check. A stream can carry video and still sound wrong because the level is too low, a track is missing, or the input’s sample rate is unsuitable. The API health information may identify sample-rate issues, but listen to the preview and verify that the intended audio reaches it. If you are building an internet radio-style channel from MP3s, the practical question of looping a folder of audio files is related, though a video relay may have different inputs and configuration.
YouTube says streams under 12 hours are automatically archived. Do not extend that statement to streams longer than 12 hours: the source page does not make that promise. If you need an archive, check the current official guidance and plan separately for what happens to a long-running broadcast and its recording.
Choose by workflow, not an untested reliability ranking
Choose FFmpeg if you want a scriptable, headless building block and are willing to manage commands, files and process monitoring. Choose OBS if you want to compose a graphical scene and can keep its application and host session available. Consider Stream247 if the dashboard, inputs and listed playlist controls match your setup, after checking the project’s current documentation and maintenance. These are fit statements, not claims that one tool is more reliable or performs better than another.
Before putting a channel on overnight, run a rehearsal using the real media and intended host. Check that the correct video and audio appear in YouTube’s preview, that the loop behaves as intended, and that you know where to look if the broadcast stops. Test the process you will actually operate, including how to restore it after a machine restart or network interruption. A short successful test cannot guarantee uninterrupted operation, but it can reveal configuration mistakes before they affect a longer broadcast.
Make the first version simple. Use one representative file or playlist, a clearly named stream, and output settings checked against YouTube’s current guidance. Keep the stream key private. Write down the steps another person would need to check the host, restart the encoder and inspect Live Control Room. Then add scene complexity, playlist changes or a different ingest protocol only when the channel has a reason for them.
If you would rather not keep your own computer running, StreamNeo removes that specific burden: you upload a video once, provide your YouTube stream key, and the cloud-run broadcast continues with your computer switched off, with monitoring and automatic restarts if it drops. It is YouTube-only; it does not replace the need to choose appropriate content, protect the key or check that your stream is set up as intended.

FAQ
Is FFmpeg the best open-source choice for a 24/7 relay?
It is the clearest documented building block here for a headless, scripted relay: the cited community example loops local media and sends RTMP from an Ubuntu VPS. That does not establish it as the most reliable option or the best fit for someone who does not want to maintain command-line configuration and monitoring.
Can OBS Studio loop prerecorded video all day?
OBS is a graphical encoder and scene tool, so it may suit a workflow where you want to compose and inspect a visible output. Check its current documentation and test the exact playback arrangement you need; the sources cited here do not provide a controlled comparison of its looping behaviour against the other tools.
Does a dashboard mean Stream247 handles every failure automatically?
No such guarantee follows from the repository’s description. It lists a dashboard, inputs and relay controls, but you should check current documentation for monitoring and recovery behaviour and decide how you will respond if the host, network or broadcast stops.
Should I use RTMP or HLS with YouTube?
Use the ingest option that fits your workflow and follow YouTube’s current instructions for it. HLS has its own segment and playlist requirements and higher latency than RTMP; do not apply its specific rules to a typical RTMP setup.
