You can use a Synology NAS to store the videos for a nonstop YouTube Live playlist, but Synology’s documented Surveillance Station Live Broadcast feature is for camera feeds—not for looping stored video files. To broadcast a playlist, the NAS must make the files available to a separate playout and encoder process, which sends the stream to YouTube. YouTube’s own encoder workflow supplies the server URL and stream key that process needs. No current, model-specific Synology setup for running that process is established here, so the exact NAS model and software combination must be verified before you rely on it.
Choose the right Synology streaming method
Start by identifying what you want YouTube to show: a camera feed or prerecorded files. The distinction matters because Synology’s cited Live Broadcast instructions select a camera and its stream profile. They do not document a playlist player for files stored on the NAS.

| Source | What sends the video | What the available documentation establishes |
|---|---|---|
| Live camera | Surveillance Station’s Live Broadcast feature | Synology documents selecting a camera and profile and entering YouTube’s RTMP path and stream key. The feature supports H.264 video. |
| Stored playlist | A separate playout process and encoder that can read NAS files | YouTube documents the encoder connection steps. The reviewed sources do not verify a current Synology model/package recipe for looping files. |
If your goal is a playlist of videos, use the second architecture. Treat the NAS as storage unless you have verified that its hardware, DSM version, and chosen software can sustain the required playout and encoding workload.
What you need for a prerecorded playlist
A self-hosted setup has three functional parts: media files accessible to the playout system, software that chooses and loops or schedules those files, and an encoder that sends a live signal to YouTube. The encoder could run on the NAS only if the specific model and compatible software support the workload; alternatively, it can run on another computer that can read the NAS files.

- NAS storage: Keep the source videos in a location the playout process can access. The reviewed sources do not specify a required file system, share path, container, or DSM menu path.
- Playout: Configure a playlist or schedule and decide what should happen when it reaches the end. Confirm that the selected software can repeat the material without manual intervention.
- Encoder: Configure the YouTube server URL and stream key in the encoder. YouTube requires a compatible live signal; the reviewed material does not establish specific encoding settings for your chosen software or NAS.
- Continuity: The NAS, encoder host, network connection, and power must remain available for a self-hosted stream to continue. A NAS storing files does not by itself ensure continuous broadcast.
Do not assume every Synology NAS can transcode continuously, or that a package or container guide for one model and DSM release applies to another. The sources reviewed for this article do not establish a supported current FFmpeg or Container Manager recipe, model-specific performance, or a safe universal bitrate and resolution. Verify those details for your exact system before leaving a stream unattended.
Connect an encoder to YouTube Live
YouTube’s encoder workflow is the common part of both a NAS-based playlist setup and other encoder-based broadcasts. Menu labels can change, so follow the current YouTube Studio interface for your account.

- Enable live streaming. Live streaming must be enabled for the YouTube account. YouTube says that enabling a first live stream may take up to 24 hours; enable it and test ahead of the time you plan to broadcast.
- Create or select a live stream in YouTube Studio. Use the stream’s setup details to obtain the YouTube server URL (also described as the RTMP path) and stream key.
- Enter the server URL and key in your encoder. Use the values for the stream you selected in Studio. Treat the stream key like a password: do not publish it, include it in screenshots, or place it in a publicly accessible configuration.
- Start the playlist and encoder, then check YouTube Studio. Confirm that YouTube receives a preview and reports stream health before you consider the setup ready for ongoing use.
- Run a supervised test. Check that the playlist advances or loops as intended and that the encoder continues sending video. Keep a local recording if the broadcast itself matters.

Synology’s documented Surveillance Station route applies to a selected camera, not a playlist of NAS files. On a compatible installation, the documented sequence is to open or enable Live Broadcast, enter YouTube’s RTMP path and stream key, then choose the camera and stream profile. Synology’s version 8 Live Broadcast help states that YouTube Live supports H.264 video, so check that the selected camera profile provides H.264. This camera workflow should not be presented as a way to play prerecorded NAS videos.

Plan for YouTube’s long-stream limits
Replay archive
YouTube says it can automatically archive a live stream that is less than 12 hours, but a stream that exceeds 12 hours may not be captured at all. For a stream that must have a complete recording, do not rely on YouTube’s replay archive as the only copy; keep a local recording or plan broadcasts shorter than 12 hours. See YouTube Help: Archive live streams.

DVR rewind
YouTube says DVR rewind may be limited or unavailable on streams longer than 12 hours. If viewers need to rewind, account for that limitation when planning long broadcasts. See YouTube Help: Use DVR on live streams.
Check rights before looping videos
Only stream videos and audio that your channel has the rights to use in a live broadcast. YouTube scans live streams for third-party content and may interrupt or terminate a stream if identified content remains. A licence alone may not prevent a Content ID interruption: where required, ask the rights owner to allowlist your channel through Content ID. Review YouTube’s copyright guidance for live streams and resolve permissions before scheduling an unattended playlist.

Choose between self-hosting and a cloud service
With self-hosting, your files can remain on your NAS and you control the playout process, but you must verify the NAS or separate encoder host, maintain the software, and keep the system, power, and internet connection available. A cloud service moves the playout workload off your home equipment, but you should evaluate its pricing, scheduling controls, credential handling, and how it expects you to establish rights to the material.
YouTube lists Gyre as a hosted option for 24/7 prerecorded-video streaming in its encoder guidance. That listing does not establish comparative price, reliability, or performance. StreamNeo is another option for a prerecorded YouTube stream: upload videos, add your YouTube stream key, and go live; it loops the uploaded material from the cloud. It is YouTube-only and does not broadcast a camera feed.
Or let it run in the cloud
If you would rather not keep a NAS or computer running the playout and encoder, StreamNeo keeps an uploaded-video YouTube stream running from the cloud. Upload your recording or build a playlist, add the YouTube stream key once, and go live. Nothing has to stay on at home; videos stream as uploaded, at any quality up to 4K 60fps for one flat price per slot. StreamNeo automatically recovers if YouTube drops the stream. The first day is free with no card, and the monthly option is $9.99 per month. Each slot includes 10 GB of storage, pooled across active slots, and the same product features; billing terms range from a day to a year, with cancellation any time. UPI and cards are accepted in India, and card checkout is available worldwide. See StreamNeo for details, or start the free first day.

| Symptom | What to check |
|---|---|
| YouTube does not show an incoming preview | Check that live streaming is enabled, the encoder is using the server URL and stream key for the selected Studio stream, and the encoder is actually sending. Re-enter credentials privately if you suspect the key is wrong; do not expose it while troubleshooting. |
| The camera broadcast will not start | Confirm you are following the Surveillance Station camera workflow, that the selected installation supports the feature, and that the camera profile provides H.264. |
| A prerecorded playlist cannot be configured through Live Broadcast | That feature’s documented workflow selects a camera; use a separate playout and encoder process for stored files instead. |
| A long stream has no complete replay or rewind | Streams exceeding 12 hours may not be archived, and DVR rewind can be limited or unavailable. Keep a local recording and plan around the duration limits if replay matters. |
| A broadcast is interrupted after playing music or video | Check rights for every component and resolve any Content ID issue with the rights owner, including channel allowlisting where required. |
Do not infer continuous reliability from a successful short test. Monitor the first extended broadcast, preserve a local copy if needed, and validate the exact Synology model and software configuration before depending on it.
