To loop video files stored on a Synology NAS on YouTube Live, use a separate encoder that reads the NAS files, repeats the playlist, and sends the resulting live feed to YouTube’s ingest URL and stream key. Synology’s documented Surveillance Station Live Broadcast feature sends camera feeds; it does not document looping local video files. Whether an encoder can run reliably on your NAS depends on its model, DSM version, codecs, processing capacity, and upload connection.
Can Synology Surveillance Station stream a video file playlist?
Not according to Synology’s documented Live Broadcast workflow. Surveillance Station’s feature is for sending a selected camera’s live feed to YouTube. Its setup asks you to provide YouTube’s RTMP path and account key, then choose a camera and stream profile; Synology says this feature supports H.264. Those instructions do not describe selecting or looping files from NAS storage. Synology’s Surveillance Station specifications and Live Broadcast help therefore should not be treated as a playlist solution.
How do I loop a video playlist to YouTube Live from a Synology NAS?
Use a file-capable playback and encoding process separate from Surveillance Station. It must read the videos, play them in order, restart at the beginning when the list ends, encode or pass through a YouTube-compatible feed, and publish continuously to YouTube. The official YouTube setup establishes the destination and encoder settings, but does not establish a particular Synology command, container image, NAS model, or playlist implementation.
- Check that your channel can go live. In YouTube Studio, open Live Control Room and create or select a stream. YouTube says first-time live streaming activation may take up to 24 hours, so enable access ahead of your planned start. See YouTube’s encoder setup instructions.
- Choose where the encoder will run. You can investigate a supported encoder process on the NAS, potentially in a container if your model and DSM release support the required tools, or run the encoder on a separate computer that reads a NAS shared folder. Do not assume a container is supported or that a NAS can encode your files in real time: verify the model’s specifications, available software, codecs, and sustained processing capability, then test the actual playlist.
- Make the video files accessible to the encoder. For an NAS-hosted process, point it to the local files; for a computer-based process, connect to the shared folder and check that the connection remains stable. Confirm that every file opens and that the encoder can advance through the playlist. Exact setup steps depend on the encoder, DSM release, file formats, and chosen architecture.
- Create or select the YouTube stream and copy its connection details. In Live Control Room, use the stream’s server URL and stream key in the encoder’s streaming destination settings. Treat the key like a password: do not put it in a public script, screenshot, repository, or forum post. YouTube’s setup flow explains how the encoder connects.
- Set a compatible output. YouTube’s current encoder guidance lists RTMP or RTMPS transport, H.264, H.265, or AV1 video, AAC or MP3 audio, and constant bitrate (CBR) encoding. YouTube recommends a two-second keyframe interval and says it should not exceed four seconds; it recommends RTMPS for encrypted transport. Synology’s camera broadcast implementation is more limited, supporting H.264, but that does not define the codec capabilities of a separate encoder. Follow the current YouTube encoder settings table for the resolution and frame rate you choose.
- Size the bitrate for your output and connection. For example, YouTube’s published table gives H.264 720p at 30 fps a 2 Mbps minimum and 6 Mbps recommended bitrate. That is one row in the table, not a universal setting. Match the row to your intended resolution and frame rate, and ensure your sustained upload capacity can support the outgoing stream with headroom for normal network variation.
- Run a private or otherwise controlled test before going public. Use representative picture movement and audio, check YouTube’s stream-health indicators and warnings, and verify that the playlist reaches the end of each item, advances to the next, and returns to the first. Listen for audio/video sync problems. Restart the encoder deliberately and confirm that it reconnects and resumes as intended before relying on it for a long broadcast. YouTube recommends testing and monitoring stream health in its encoder guidance.
- Plan for the archive duration. YouTube says streams under 12 hours are automatically archived. Do not rely on one complete automatic archive for a continuous stream longer than 12 hours; arrange separate archive segments or local recordings if preserving the full program matters. See YouTube’s live-stream setup help.
Choose between encoding on the NAS and using a computer
| Approach | Advantage | Trade-off | Check before committing |
|---|---|---|---|
| Encoder process on the NAS, potentially in a supported container | Reads NAS files locally and may avoid leaving a desktop computer running. | Model and DSM compatibility, real-time encoding capacity, and recovery behavior must be verified; no specific container or playlist setup is established here. | Processing capability, codec support, whether Container Manager is available for your setup, restart behavior, and monitoring. |
| Encoder on a separate computer reading a NAS share | Moves the encoding workload off the NAS and allows use of desktop encoder tools. | The computer must stay powered on and maintain reliable access to the shared files. | Network throughput, stability, power use, encoder controls, and how quickly you can recover from a failure. |
Neither approach is guaranteed by the title alone: the NAS model, DSM version, video codecs, playlist, and upload speed all affect feasibility. Test the full chain with your own files and connection.

Copyright and channel checks before looping videos
Only stream material you have the rights and permissions to broadcast. A file being stored on your NAS does not establish permission to rebroadcast it. Review YouTube’s applicable copyright rules and your channel’s monetization policies before scheduling a long-running playlist; looping the same content does not itself establish that a channel qualifies for monetization.
Troubleshoot common failures
- YouTube does not receive a signal: Check that live streaming is enabled for the channel, the stream is active in Live Control Room, and the encoder uses the matching server URL and current stream key. Check the network connection and any firewall rules affecting the chosen RTMP or RTMPS transport.
- The stream starts but has health warnings or drops: Compare the encoder output with YouTube’s current codec, CBR, keyframe, bitrate, resolution, and frame-rate guidance. Check sustained upload capacity rather than relying on a brief speed test; reduce output demands if the connection cannot sustain them.
- The playlist stops at the end of a file: The playback process may not be configured to advance or repeat. Verify the playlist order and repeat behavior locally, then test the full transition back to the first item while monitoring YouTube.
- Files play locally but fail through the encoder: Check whether the encoder supports each file’s container, video codec, audio codec, and frame rate. A successful file copy to the NAS does not prove the encoder can decode it.
- The NAS process stalls or falls behind: The workload may exceed available processing capacity, or storage/network access may be interrupted. Test on the specific NAS and consider moving encoding to a computer that reads the shared folder if NAS resources are insufficient.
- The stream does not recover after a restart: Check whether the encoder process is configured to start again, reconnect to YouTube, and reopen the playlist. Test planned restarts and monitor the stream rather than assuming automatic recovery.
- The saved YouTube archive is incomplete: YouTube’s automatic archive applies to streams under 12 hours. For longer continuous programs, use planned segments or make a separate local recording.
