SRS on a Windows PC for YouTube loop streaming needs a qualification: the consulted SRS project materials do not document an end-to-end Windows-native setup. They list Linux and macOS as supported platforms, so this setup guide explains the roles and a bounded workflow rather than claiming a verified Windows installation recipe.
For a single prerecorded loop, SRS may not be needed at all. You can publish from OBS or FFmpeg directly to YouTube Live; put SRS in the path only if you have a clear relay or media-server need and a host you can operate and test.
What this Windows guide can and cannot verify
The current SRS project README identifies SRS as a real-time media server and lists Linux and macOS among its supported platforms. It shows an OBS custom-service example and an FFmpeg publishing example. Those examples clarify how a publisher can send media to SRS, but they do not establish a supported native Windows installation or prove that a Windows PC can run the whole arrangement reliably.
That distinction matters because a Windows PC can be part of a workflow without SRS itself being installed natively on Windows. For example, OBS could run on Windows while SRS runs separately in an environment covered by the project’s documented platform guidance. This is an architectural possibility, not a complete setup tested or guaranteed by the cited material. The SRS v7 getting-started build documentation is Linux-oriented; do not treat it as instructions for building an officially supported Windows version.
The practical guide below separates the components, describes a documented SRS example, and sets out what to check before a real broadcast. It does not prescribe unverified Windows commands, containers, ports, firewall changes or scripts. If your requirement is simply to get one loop to YouTube, start with direct publishing and add SRS only when you can explain what it is doing for you.
Separate the loop source, publisher, SRS and YouTube
Think of this as four jobs, not one application. The loop source is your prerecorded video or playlist. The publisher reads or plays that media and encodes it for sending. SRS, if included, receives and serves or relays media using supported protocols. YouTube Live is the destination where the channel’s stream is configured and broadcast.
A straightforward path is video file → OBS or FFmpeg → YouTube Live. A path with SRS is video file → OBS or FFmpeg → SRS → YouTube Live. The SRS examples support a publisher sending to an SRS RTMP URL, but the precise onward relay configuration to YouTube is not established by those examples. Plan and validate that second connection separately rather than assuming that entering the YouTube key into an SRS form will complete the job.
For a devotional channel, the source might be one long bhajan recording or a prepared sequence of bhajans and aarti. For a study station, it might be a quiet visual loop with background audio. Decide first whether the media itself is a single file or a playlist, and how it returns to the beginning. A source that stops at the end is not an always-on loop merely because a server is present.
Adding SRS brings another component to configure and monitor. It may make sense where you need an intermediary for a wider workflow, but it does not automatically make a single YouTube stream more reliable. If a direct OBS test is enough for your channel, reducing components can make faults easier to locate. For playlist behaviour and transitions, see this guide to switching between bhajans and aarti in a devotional stream.
Choose OBS or FFmpeg as the publisher
OBS is useful when you want to see the media, add a scene or overlay, monitor audio and change settings through a graphical interface. FFmpeg is useful when the input is a file and you want a command-driven publishing process without a composed scene. Neither choice removes the need to test the loop, encoding load, network and restart behaviour.
OBS’s system requirements list Windows 10 or Windows 11 and a DirectX 10.1-compatible GPU as basic requirements. OBS warns that meeting them does not ensure that a given computer can stream or record well: CPU demands vary with the encoder, resolution, frame rate and scene complexity. Use OBS’s Auto-Configuration Wizard as a starting point, then test with the actual media and output settings you intend to use. A static landscape scene and a busy animated layout do not place the same demands on a machine.
With FFmpeg, confirm that your source plays from beginning to end and that your chosen command handles the end of the file in the way you intend. The SRS README includes an FFmpeg example publishing a file to an SRS RTMP URL, but that example is not evidence of a complete Windows workflow. If you are not already comfortable maintaining command-line processes, OBS may be easier to inspect when something goes wrong.
| Choice | Where it sends the stream | Useful when | What you still need to test |
|---|---|---|---|
| OBS direct | OBS to YouTube Live | You want a visible scene, controls and a direct path | Scene, encoder load, loop end behaviour, network and Live Control Room preview |
| FFmpeg direct | FFmpeg to YouTube Live | A file-based, command-driven process suits your workflow | File looping, command restart, encoding and YouTube ingest |
| OBS or FFmpeg via SRS | Publisher to SRS, then onward to YouTube | You have a specific relay or media-server requirement | SRS host, each connection, onward output, restarts and monitoring |
For any route, follow YouTube’s current encoder requirements rather than copying settings from an unrelated channel. YouTube’s encoder settings guidance lists RTMP or RTMPS, H.264, H.265 or AV1 video, AAC or MP3 audio, constant bitrate and a recommended two-second keyframe interval that should not exceed four seconds. It supports up to 60 fps. The appropriate values depend on your source, encoder and connection; settings that are accepted are not a promise of a stable night-long broadcast.
Understand the documented SRS RTMP example
The SRS README’s OBS example uses a custom service with server rtmp://localhost/live and stream key livestream. In that example, OBS publishes to SRS on the same host. The address is an example for that arrangement, not a YouTube ingest URL, not a Windows-specific configuration, and not a value to paste into your channel’s YouTube Live settings.
The README also demonstrates FFmpeg publishing a file to an SRS RTMP URL. Read that as evidence of the general publisher-to-server relationship: FFmpeg supplies encoded media, and SRS receives it. It does not show the complete second leg from SRS to YouTube, describe a supported Windows host, or explain the supervision needed for a 24/7 service. Avoid filling these gaps with guessed configuration copied from a different SRS release or operating system.
Before introducing SRS, draw the path on paper and label every address and key. Your publisher’s output target and YouTube’s ingest details belong to separate connections if SRS is between them. Identify which process sends to each destination, which machine runs it, and what you will inspect if the preview disappears. If you cannot answer those questions yet, first test a direct OBS or FFmpeg stream to YouTube.
This is also where a relay can increase fault-finding time. A black preview might come from the source, the publisher, the connection to SRS, SRS itself, the onward connection, or YouTube ingest. A direct path has fewer places to check. For a visual check of one common OBS problem, the black-screen troubleshooting guide offers a separate set of checks.
Plan a supported host for SRS
If SRS is genuinely required, plan to run it on a supported host rather than assuming your Windows desktop is one. The project README’s listed platforms and its build documentation give a Linux-oriented route; they do not validate a particular cloud host, virtual machine, container arrangement or Windows Subsystem for Linux configuration for this use. Choose an environment you can administer, patch and monitor, and verify its current SRS instructions before deploying.
Keep the Windows PC’s role explicit. It might hold the media and run OBS, while a separate supported host runs SRS. That creates a network connection between them, and then another connection from SRS towards YouTube. If the PC sleeps, reboots for updates or loses broadband, the source or publishing leg may stop even if SRS remains available. If SRS stops, the opposite is possible: the publisher continues sending, but the onward path fails. A component does not take responsibility for failures in the others.
Compare this with publishing from a VPS or another supported host, where the source and publisher might also run remotely, or with a managed workflow where you upload media and let a service handle continuous playback. Each approach changes what you maintain yourself. A local PC gives you direct access to the files and controls, but depends on that PC and its connection staying available. A separate host adds administration and network configuration. A managed workflow may reduce day-to-day computer operation but gives you less direct control over the underlying process. This cloud PC versus VPS comparison for pre-recorded YouTube Live in India can help frame the hosting decision without implying that SRS is necessary.
Do not buy a capture card, webcam or microphone just because you are setting up a prerecorded loop. The source and production determine what equipment is useful. A wired Ethernet connection is a practical option for a stationary PC if Wi-Fi is inconsistent, not a documented requirement. Whatever the arrangement, write down how you will restart the source, publisher and SRS independently, and how you will know which one stopped.
Connect to YouTube Live and test the loop
YouTube’s encoder workflow begins in Live Control Room: create or select a stream, copy the server URL and stream key, enter them in the encoder, start sending, wait for the preview, and then go live. The official encoder setup instructions describe that flow. Treat the stream key as a password: keep it out of screenshots and public notes, and reset it if it is exposed. The YouTube destination settings are not the same as the local SRS example’s livestream key.
Check channel access before you prepare a long loop. YouTube says live streaming requires channel verification and no live-streaming restrictions in the past 90 days; first-time activation can take up to 24 hours. Those are YouTube’s stated conditions, not a guarantee of approval for any particular channel. Review the current official help page and resolve access before relying on a planned start time.
Select output settings in light of the source and the connection you can sustain. YouTube’s live encoder settings table gives H.264 guide values of 5 Mbps minimum and 14 Mbps recommended for 1080p30, and 3 Mbps minimum and 8 Mbps recommended for 720p30. These are guidance values, not guarantees. YouTube also recommends upload headroom of 20 per cent in its streaming tips. Check sustained upload capacity at the location and time the stream will run; a speed test at a quiet hour does not establish overnight performance.
Make a representative test before committing to a long broadcast. Include the real audio, motion, resolution and any scene changes, then inspect the Live Control Room preview and stream health. Listen for clipping, silence or an audio-video mismatch, and check that the image is not frozen or unexpectedly cropped. Keep the test long enough to catch a file ending or playlist transition, and repeat it after changing the source, encoder settings or network route. A setting that worked for a short test may not reveal how your process behaves on a restart.
An always-on plan also needs an answer for interruptions and archives. YouTube says streams under 12 hours are automatically archived. That statement does not promise that a longer 24/7 session will be preserved, restart seamlessly or remain online indefinitely. If your channel needs an archive, plan and test how you will divide sessions, restart broadcasts and handle recordings; check the current YouTube guidance rather than assuming an unbroken stream becomes a complete permanent video. For more on the settings trade-offs in a continuous audio stream, read the encoder settings guide for a 24/7 rain-sounds stream.
During operation, assign someone to check the preview and stream health, especially after initial launch and after any restart. If you rely on a local PC, account for Windows updates, sleep settings, power loss and broadband interruptions. If you rely on SRS, monitor it separately from the publisher and YouTube. No single “start” button tests all the links in the chain.

FAQ
Can SRS run natively on Windows?
The consulted current SRS README lists Linux and macOS as supported platforms, not Windows. That does not establish a supported native Windows setup, so this guide does not offer one as an official recipe. Check the project’s current documentation before choosing a host.
How do I send a loop to YouTube Live?
The simplest path is to use OBS or FFmpeg to publish the media to YouTube’s server URL with the stream key from Live Control Room. Test the loop, preview, audio and stream health before going live. Add SRS only if you have a specific relay requirement and have validated both legs of the connection.
Will YouTube archive a 24/7 stream?
YouTube says streams under 12 hours are automatically archived. That does not establish archive handling for an uninterrupted stream beyond that boundary. Plan for session segmentation and check the current official YouTube guidance if preserving recordings matters.
