For a 24/7 pre-recorded YouTube stream on Linux, start by deciding whether you need a player to repeat a file or a complete setup that also sends it to YouTube Live. OBS is the clearest graphical starting point for one looping video; mpv is a command-line playback option with an infinite-loop setting, but it does not send a stream to YouTube by itself.
There is no evidence-backed universal winner for “lightweight”. The useful comparison is about workflow: one file or a playlist, graphical controls or command-line operation, and how you will encode, deliver, monitor and recover the live broadcast.
Playback is only one part of a live stream
A player reads and presents media. A YouTube live stream also needs an encoder connection that packages video and audio for delivery to YouTube. A player’s ability to loop a file does not establish that it can create or maintain that connection.
OBS brings media sources and streaming controls together in a graphical workflow. With a headless Linux setup, you may use a player for playback and a separate streaming and encoding tool such as FFmpeg. That division can suit someone comfortable with command-line configuration, but it means you need to verify the full pipeline, not just that the video repeats.
YouTube’s encoder setup guidance describes connecting an encoder using a stream URL and stream key, then checking the preview in Live Control Room. Keep the key private. Before scheduling a broadcast, confirm that live streaming is available to your channel and check YouTube’s current requirements; eligibility or a valid connection should not be assumed from the choice of player.
If you are weighing a graphical workflow against a separate encoding path, the practical distinction is similar to the one in this guide to setting up a YouTube live-streaming server. Whichever approach you choose, the final test must cover both the media source and the output seen by YouTube.
OBS for a graphical workflow
OBS Studio is a sensible first choice when you want visible controls for sources, audio, scenes and the live connection in one application. Its official documentation covers Media Source on Linux and includes a Loop option for a local file. That gives you a direct way to repeat one prerecorded video without manually restarting playback.
The advantage here is not a claim that OBS uses fewer resources than another player. The documentation establishes the looping feature, not a controlled CPU, memory or long-running reliability comparison. Choose it because the interface makes it easier to inspect what is playing and configure the broadcast in one place.
A GUI also makes some mistakes easier to spot: a muted source, a wrong file, an unexpected scene or a preview with no picture is visible before you go live. It does not remove the need to check audio, network capacity and stream health, nor does an open OBS window prove that YouTube is receiving a healthy broadcast.
If the machine is an everyday desktop, a GUI may be the more manageable operational choice even if a command-line process appears more minimal. Consider who will notice a problem overnight and who can correct it. A setup that only its creator knows how to restart is a poor fit for a shared devotional channel, local news loop or small business display.
For a broader checklist of channel decisions before configuring software, see how to live stream a hobby on YouTube. The useful principle is to settle the broadcast’s purpose and content first, then choose the workflow you can operate and check consistently.
Loop one file with Media Source
For a single local video, add an OBS Media Source and select the file you intend to broadcast. Enable its Loop setting, then watch the source through a full restart point: the end of the file, the transition back to the beginning, and the audio at that transition. A visible looping control is not a substitute for listening to the resulting programme.
Check the file before the live session. Confirm that the chosen media opens in OBS, its aspect ratio is sensible in the canvas, and its audio is present at an appropriate level. If you have a long devotional recording or ambience video, sample the beginning and end rather than assuming that a file that plays in another desktop application behaves identically as a source.
The source file and the live output are separate checks. OBS can play the media locally while its output is misconfigured, and YouTube can receive a stream that has the wrong scene or no useful audio. Run a private or otherwise appropriate test using the same scene, media and output settings you expect to use for the public channel.
A loop can also expose an editorial issue that a one-off viewing hides. A sudden cut from the end to the start may be noticeable; an audio tail may not join cleanly. If a seamless join matters, adjust the file itself or choose content designed to repeat. For practical options on loop transitions, this article on looping a long rain video without restarting the YouTube stream addresses the content side of the problem.
Use VLC Video for a playlist
If your programme uses several local videos, OBS documents a VLC Video source with a Loop Playlist option. VLC must be installed for the source to be available, and OBS notes that a 64-bit OBS installation needs a matching 64-bit VLC installation. Check that dependency before building a scene around it.
A playlist is useful when you want an ordered sequence or a rotating collection rather than repeating one file. Prepare the playlist deliberately: confirm the paths remain available after reboot, the order is what you expect, and each item has compatible audio and picture levels. Test the transition between each pair of representative items; changes in loudness or framing can be more disruptive than the loop itself.
The extra capability has a cost in setup and troubleshooting. You now depend on VLC being installed in a form OBS can use, as well as on the playlist and every media file remaining accessible. The feature documentation confirms playlist looping; it does not establish that this arrangement is the lightest or proven to stay up for a particular duration.
For a channel where the programme alternates bhajans, announcements and quiet intervals, decide whether a fixed order is appropriate before enabling a playlist loop. If a stream needs a predictable sequence, inspect it from the first item through the return to the beginning. The comparison of OBS playlist and VLC sources for a 24/7 Indian music stream can help clarify which source arrangement matches that kind of programme.
Consider mpv for command-line playback
mpv is a command-line media player, and its manual documents infinite looping. That makes it a candidate when you want playback without a full graphical player interface or when you are building a headless workflow. It is a feature-based fit, not proof that mpv is more lightweight, reliable or better than OBS on your particular machine.
The loop option solves only the playback question. You still need a method to encode and send the video and audio to YouTube, plus a way to see whether the output remains healthy. A headless approach commonly separates playback from the streaming and encoding stage, for which FFmpeg is a relevant class of tool. Do not treat a player command as a complete YouTube live command, or assume that a process continuing to run means the public stream is sound.
Command-line operation can be useful where there is no desktop session or where an administrator already maintains scripts and process supervision. It can also make recovery less accessible to someone who expects a visual interface. Before adopting it, write down how to start the pipeline, how to detect a failed process, how to inspect logs or output, and who will respond if the picture or audio disappears.
The mpv project notes that hardware decoding may help when CPU decoding is too slow, but hardware decoding must be explicitly enabled. That is a possible configuration to investigate, not a guarantee of lower resource use in every combination of graphics hardware, drivers and media. Test with your actual file and machine rather than inferring performance from the player’s name.
If the video is only for local display, mpv or VLC may be enough. For YouTube delivery, keep the encoder and transport requirements in view. YouTube’s live encoder settings recommend matching bitrate to resolution, frame rate and codec, and monitoring stream health. Those recommendations concern ingest settings, not a promise that your internet connection can sustain them.
Plan encoding, bandwidth and monitoring
The selected player does not determine a suitable output bitrate by itself. Choose the resolution, frame rate and codec your encoder supports, then compare the resulting settings with YouTube’s current encoder guidance and the sustained upload capacity at the stream location. Leave network headroom and test at the time and place you plan to broadcast; a speed result at another location or time is not a guarantee of overnight stability.
For context, YouTube’s encoder settings page, accessed in 2026, lists H.264 at 1080p and 30 frames per second with a 5 Mbps minimum and 14 Mbps recommended bitrate. For H.264 at 720p and 30 frames per second, it lists 3 Mbps minimum and 8 Mbps recommended. These are platform ingest recommendations, not measurements of your connection or promises that those rates will work reliably for you. Check the current table before configuring a stream, especially if using a different codec or frame rate.
YouTube recommends RTMPS in its encoder guidance and specifies key configuration details such as constant bitrate and keyframe intervals. Follow the current official settings for the encoder you actually use; a player comparison cannot validate the output codec or connection. For a pre-recorded stream, test the same media with representative audio and video rather than a short unrelated sample.
During a test, inspect the Live Control Room preview and stream health, then listen and watch for issues that a running process cannot reveal. Decide how often someone will check the channel and what they will do if the connection drops. If you use a command-line pipeline, include process supervision and monitoring in the plan rather than assuming that looping playback automatically restarts a failed stream.
A 24/7 broadcast also has archive and rewind implications. YouTube Help says streams longer than 12 hours may not be captured at all, and DVR rewind may be limited or unavailable for broadcasts longer than that. If retaining a complete recording matters, plan a local recording or shorter sessions and check YouTube’s current live-stream archive guidance and DVR help before relying on a platform archive.
Compare by the job your setup must do
Use the table to compare documented functions and workflow trade-offs, not performance rankings. The available evidence does not establish a universal lightest option or prove how long any choice will run without interruption.
| Option | Suits | Documented function | Trade-off to plan for |
|---|---|---|---|
| OBS Media Source | One local video with graphical controls | Linux support and a Loop setting for a file | Does not prove a resource advantage or 24/7 endurance |
| OBS VLC Video source | An ordered or shuffled collection of local videos | Loop Playlist option; VLC must be installed | Adds a matching VLC dependency and playlist maintenance |
| mpv | Command-line or minimal-interface playback | Manual documents infinite looping | Playback is not YouTube delivery; no comparative benchmark established |
| FFmpeg with a playback source | A headless encoding and transport pipeline | Relevant tool category for stream encoding | Requires tested configuration, monitoring and recovery planning |
For one file and a visible interface, begin with OBS Media Source and test its Loop setting. For a playlist, consider the OBS VLC Video source if you are comfortable installing and maintaining the matching VLC build. For a headless machine, mpv may cover playback while a separate encoder handles delivery; verify the exact media, codecs, output settings and monitoring before relying on it.
Your available machine matters, but avoid guessing based on labels such as “lightweight”. Try the intended source and output settings on the actual Linux system, watch for dropped frames or encoding warnings, and check the result in YouTube’s preview. If you are adapting a high-resolution source, review how to resize 4K videos to 1080p for a YouTube loop stream before assuming the player alone will solve a mismatch between media and output.
Finally, choose the arrangement someone can maintain. A graphical setup may be easier for a non-technical operator to inspect; a headless setup may suit a machine already managed through scripts, provided recovery and monitoring are explicit. Neither replaces a content check, a connection test or an archive plan.

FAQ
Does mpv send a video directly to YouTube Live?
No. mpv is a media player, and its documented infinite-loop feature covers playback. You need a configured encoder and output path to deliver a live stream to YouTube.
Which is better for one looping video, OBS or VLC?
OBS Media Source is a straightforward graphical starting point because it has a documented Loop setting for a local file. VLC may suit local playback, but the cited material does not establish it as a uniquely lightweight YouTube streaming solution; compare the workflow you actually need.
Can a 24/7 stream be archived completely on YouTube?
Do not assume so. YouTube says streams longer than 12 hours may not be captured, and DVR rewind may be limited or unavailable beyond that duration. If a complete archive matters, plan a local recording or shorter sessions and verify current YouTube guidance.
How do I know whether my Linux setup is suitable?
Test the actual source file, audio, encoder settings and sustained upload connection, then inspect the YouTube preview and stream health. Choose a workflow you can monitor and recover; there is no evidence-backed universal player winner or uptime guarantee.
