A Synology NAS can store the videos for a YouTube Live playlist, but Surveillance Station’s documented Live Broadcast feature sends camera streams, not local video files. To loop files from a NAS, you need a separate encoder process that reads the files, plays them in order and sends a continuous feed to YouTube.
The practical question is not simply whether the NAS can hold the videos. It is whether your particular NAS and software can read and encode them reliably, or whether a separate computer should do that work. Plan the playlist and encoder as separate jobs, then test the complete path before making the channel public.
What Synology Live Broadcast is documented to do
Synology describes Live Broadcast in Surveillance Station as a way to send live camera streams to YouTube. Its help flow has you enable or open Live Broadcast, enter YouTube’s RTMP path and account key, choose a camera, and select a stream profile. Synology’s technical specifications say the Live Broadcast function supports H.264.
Those details are useful if your source is a camera connected to Surveillance Station. They do not establish that Surveillance Station can choose files from a NAS folder, arrange them as a playlist, and play them repeatedly to YouTube. The Surveillance Station specifications and Synology’s Live Broadcast instructions describe the camera-oriented feature. Treat that distinction as the starting point for choosing a workflow, rather than assuming a similarly named broadcast setting can also handle pre-recorded media.
A NAS is a storage device and, depending on its model and configuration, a computer capable of running other software. Those are different roles. Having video files in a shared folder does not by itself provide the playback, playlist sequencing, encoding and stream-publishing functions required for a continuous live broadcast.
Why camera broadcast is not a local video playlist
A camera feed is already a live source: Surveillance Station receives it and the documented broadcast feature forwards a selected camera stream. A playlist of pre-recorded files needs software to open each file, move to the next one at the right time, repeat the sequence, and produce a live-compatible output. The playlist must continue running even though no camera is supplying the source.
That difference matters when you are assessing instructions found in a forum or an old setup guide. A screenshot showing a YouTube URL and a stream key in Surveillance Station proves that a camera stream can be connected using that feature; it does not prove that a folder of MP4 files can be selected or looped there. If you are asking, “Can Synology Surveillance Station stream a video file playlist?”, the documented answer is that its Live Broadcast help describes selecting a camera, not selecting local media files.
A useful way to avoid a wrong turn is to write down the source and the output separately. Your source is a set of files on a NAS share. Your output is a continuous encoded stream sent to YouTube. A file-capable encoder has to bridge the two; Surveillance Station’s camera broadcast documentation does not provide that playlist step.
There is also a difference between a YouTube playlist and a live broadcast playlist. A YouTube playlist groups uploaded videos for viewers to watch on demand. A live stream encoder, by contrast, sends one continuing feed, with the transitions between pre-recorded videos happening before YouTube receives the feed. If you want a continuous programme, you need the latter behaviour from your playback and encoding process.
Confirm YouTube live-streaming eligibility
Before you set up the encoder, sign in to the channel that will host the stream and confirm that live streaming is enabled. YouTube says first-time activation may take up to 24 hours, so do not leave this check until the evening you plan to begin. Select or create the stream in YouTube Studio’s Live Control Room and keep the stream details available for the encoder configuration.
The YouTube live encoder setup guide explains how to choose a stream and connect an encoder. YouTube provides a server URL and stream key for that connection. The key is a credential: anyone who obtains it may be able to send a feed to the stream, so keep it out of public scripts, screenshots, repositories and forum posts. Store it only where the encoder needs it, and replace it in YouTube Studio if it is exposed.
Confirm which stream you have selected before you copy credentials. It is easy to configure an encoder with the key for a test stream and later start publishing to the wrong destination. Keep a private note that identifies the channel and stream without recording the key in an unsecured document. If another person helps with setup, share access using the appropriate account permissions rather than posting the key in a public support request.
A successful connection is not the same as permission to use everything in your videos. You remain responsible for checking the rights and terms that apply to the material you stream. YouTube’s tools and live-streaming approval do not guarantee that a particular programme will avoid a claim or restriction; check current official guidance where that question matters.
Choose a separate encoder process for NAS files
There are two practical architectures to assess. In the first, a compatible encoder runs on the NAS and reads the files locally. In the second, an encoder runs on a separate computer and reads the videos through a NAS shared folder. In either case, the software needs to support file playback, sequencing or looping, and live output to YouTube. The title alone tells us neither that your NAS can run such software nor that a particular playlist command will work.
| Approach | What it can suit | What you need to verify |
|---|---|---|
| Encoder process on the NAS | Reading files stored on the NAS without leaving a desktop computer running | Compatibility with your NAS model and DSM release, available encoding capability, supported file formats, restart behaviour and monitoring |
| Encoder on a separate computer | Moving playback and encoding work away from a NAS with limited processing capacity | The computer must stay powered on, access the shared folder reliably, sustain the upload and recover cleanly after a restart |
A containerised encoder may be one way to run software on a NAS, but availability and suitability depend on the model, DSM release and the software chosen. The official sources cited here do not establish a tested container image, command, playlist configuration or compatible NAS model. Check Synology’s documentation for your device and the encoder’s own documentation before relying on it. If the instructions assume a command-line option or package that you cannot verify for your setup, do not treat it as a confirmed Synology feature.
For a NAS with limited encoding capacity, a computer connected to the same network can read the NAS share and do the encoding. That shifts the load off the NAS but adds another machine that must remain switched on and connected. A desktop encoder may be easier to inspect and control, while an encoder process on a supported NAS may avoid depending on a separate computer. Neither arrangement removes the need to test file access, playback, stream output and recovery.
If you want a more detailed comparison of where a long-running encoder can sit, the VPS or cloud PC discussion for 24/7 streaming in India lays out a different hosting decision. For the NAS question, use it as a reminder to compare who must stay powered on and who carries the encoding workload, not as evidence that any particular NAS can run a playlist encoder.
The main practical trade-off is control versus dependence. Keeping the encoder on a computer can make logs, previews and settings easier to reach, but the computer and its connection to the NAS become part of the broadcast path. Running it on a NAS may reduce the number of active devices, but you need confidence in that model’s software support and sustained capacity. Choose based on checks you can perform on your own equipment, not on the assumption that all Synology models behave alike.
Supply YouTube’s ingest URL and stream key
Once the encoder can read the files and produce a feed, configure it with the server URL and stream key shown for the selected YouTube stream. YouTube’s setup flow uses these values to connect the encoder to the destination. Keep them private, and avoid putting the key into a script that will be published or shared. If your encoder offers a secure settings store or a private configuration file, use it and restrict access to the people who need it.
YouTube’s current encoder guidance lists RTMP and RTMPS as ingest protocols, video codecs including H.264, H.265 and AV1, and AAC or MP3 audio. It recommends constant bitrate encoding and a two-second keyframe interval, with the interval not exceeding four seconds. Consult the YouTube encoder settings guidance for the current requirements and the table that matches your chosen output. The four-second figure is a maximum interval in that guidance, not a reason to choose settings without checking the rest of the configuration.
Where the encoder supports it and YouTube provides the relevant endpoint, prefer RTMPS for encrypted transport. Match the video and audio codecs to both the encoder’s capabilities and YouTube’s current ingest guidance. Do not assume that a file’s codec is necessarily the right live output: the encoder may need to decode the source and re-encode it for the stream.
YouTube’s table gives H.264 at 720p and 30 frames per second as an example with a 2 Mbps minimum and 6 Mbps recommended bitrate. That is one row in the table, not a universal setting for every playlist or upload connection. Choose the row for your intended resolution and frame rate, then consider whether your sustained upload can carry the output consistently. The video resizing guide for a YouTube playlist stream can help you think through source dimensions, but resizing a file does not make a weak upload connection reliable.
Check NAS encoding capability and test performance
There is no NAS model, DSM version, file format or network measurement specified by this question. For that reason, it would be misleading to say that a particular Synology model can encode and publish a playlist. Check the specifications for your own model and DSM release, then verify that the encoder you intend to use supports the needed playback, codecs and output on that system.
Separate decoding from encoding in your checks. If your video is already in a format the encoder can pass through, the work may differ from a setup that must decode and re-encode every frame. A software encoder may use the processor heavily; hardware-assisted encoding is only relevant if both the device and chosen software support it for the formats in your files. Look for evidence in the device and software documentation rather than assuming that a media playback feature means live encoding is supported.
Test with the actual files you plan to broadcast, not a short sample in a different format. Include the longest or most demanding material, and watch the NAS and encoder while the stream is running. Check whether the output remains steady, whether the files continue to be read from the share, and whether the encoder reports errors or warnings. A test that succeeds briefly does not establish that a system will keep working unattended overnight.
The network path matters as much as processor capacity. The encoder must read the files from storage and maintain an upload to YouTube. If the separate computer is on Wi-Fi or the NAS is connected over a congested network, interruptions may occur even when the encoder itself is configured correctly. Measure the actual connection during representative use and allow room for normal variation rather than targeting the full measured upload capacity.
Plan recovery as part of the test. Restart the encoder deliberately while a private or unlisted test stream is active, then check how it reconnects and whether playback resumes at a sensible point. Confirm what happens after a NAS restart, a network interruption or a temporary loss of the shared folder. A process that starts successfully once is not necessarily configured to restart unattended. If maintaining that recovery path requires repeated manual work, it may be a poor fit for a 24/7 channel.
If the difficult part is keeping a personal computer switched on and recovering the broadcast after a drop, StreamNeo removes that specific operational burden by running an uploaded video as a YouTube stream without your computer left running. It does not turn Surveillance Station into a playlist encoder, and it is a YouTube-only workflow; decide whether that fits the way you intend to manage the files and channel.
Validate the preview before going live
Start with a private or unlisted test where appropriate, and inspect the preview in YouTube Studio before making the stream public. YouTube recommends testing and monitoring stream health. Use representative material: a quiet devotional track, a scene with movement, a news segment with speech, or whatever best reflects your real programme. A still image and silence are not enough to reveal timing and audio problems.
Check that the first file starts, reaches its end, and is followed by the next file. Then let the sequence complete and verify that it returns to the first item if the playlist is meant to repeat. Listen for gaps, abrupt volume changes, silence, clipped starts and audio that drifts out of sync. Watch for black frames or unexpected aspect-ratio changes at transitions. These are playlist and source checks, separate from YouTube’s ingest health indicators.
If the encoder reports dropped frames, unstable connection or other warnings, do not assume viewers will see the same thing you see locally. Review YouTube’s stream health messages, compare them with the encoder’s own status, and adjust one setting at a time. A lower output setting may help if the connection cannot sustain the chosen feed, but it should still match a supported row in YouTube’s current guidance and remain acceptable for the material.
For longer broadcasts, understand the archive limitation before relying on the stream as your only recording. YouTube says streams under 12 hours are automatically archived. Do not assume that a continuous broadcast lasting longer than 12 hours will produce one complete archive. If preserving the whole programme matters, plan separate archive segments or keep a local recording, and check YouTube’s current help before building an archive process around an assumption.
A test should include a realistic handover or restart, not only an uninterrupted run. Confirm that the encoder can recover after a planned restart and that the stream resumes in the way you expect. For more on diagnosing a dropped encoder connection, see the guide to YouTube stream disconnections from OBS; its troubleshooting context is different, but the habit of checking both the encoder and YouTube status is relevant.
Write down the chosen output settings, the order of files, and the recovery steps in a private operating note. Leave out the stream key. If someone else may need to restart the broadcast, make the note specific enough to guide them without exposing credentials. Revisit the test whenever you change the playlist, output settings, encoder software or network arrangement.

FAQ
How do I loop a video playlist to YouTube Live from a Synology NAS?
Use a separate file-capable encoder process that reads the NAS files, plays them in sequence and publishes a continuous feed to YouTube’s server URL and stream key. Decide whether that encoder can run on your NAS or should run on a separate computer, then check compatibility and test the complete playlist before going public.
Can Synology Surveillance Station stream a video file playlist?
The documented Live Broadcast feature is for sending live camera streams to YouTube. Synology’s help describes selecting a camera, not selecting local video files or looping a playlist, so do not rely on that feature for this task.
Can every Synology NAS encode a 24/7 playlist?
No model or DSM version is specified here, and capability depends on the device, software, codecs and sustained workload. Check the documentation for your particular NAS and encoder, then run a representative test long enough to observe performance and recovery.
Will YouTube archive the whole continuous broadcast?
YouTube says streams under 12 hours are automatically archived. Do not count on one complete archive for a longer continuous stream; plan archive segments or a local recording if keeping the full programme matters, and verify current YouTube guidance.
