You can loop videos from a local folder in OBS and send them to YouTube Live, but the loop alone does not make a stream reliably 24/7. Your computer, files, OBS, power, internet connection, and YouTube ingest must all keep working. For multiple videos, OBS’s VLC Video Source can play a playlist and loop it; for a single video, use a Media Source with Loop enabled.
Before you begin: enable YouTube Live
Your channel must be verified and must not have had a live-streaming restriction in the previous 90 days. YouTube says enabling live streaming for the first time may take up to 24 hours, so do this well before the planned start. See YouTube’s live-streaming tips and encoder setup guidance.
- Open YouTube Studio and go to the Live Control Room.
- Create or manage an encoder stream and retrieve its stream configuration and key.
- Keep the stream key private. Treat it like a password: anyone who obtains it may be able to send a feed to your channel.
Set up a local video source in OBS
For one video: use Media Source
- In OBS, create or select a scene, then add a Media Source.
- Select Local File and browse to the video.
- Enable Loop if the file should replay continuously.
- Check the preview for framing and crop, and confirm the audio meter responds as expected.
For a folder of videos: use VLC Video Source
- Install VLC. If your OBS installation is 64-bit, install 64-bit VLC as well; the VLC Video Source depends on VLC being installed.
- In OBS, add a VLC Video Source to your scene.
- Add the local video files to its playlist in the order you want them played.
- Enable Loop Playlist to restart playback after the final item. Shuffle Playlist is off by default, so files normally play in list order.
- Check that each file plays through to its end, that transitions work acceptably, and that audio is present. OBS documents playlist looping, but does not promise gap-free transitions for every file and codec combination.
OBS lists common supported local video formats including MP4, TS, MOV, FLV, MKV, AVI, GIF, and WebM. See the OBS Media Sources guide and OBS Sources Guide. Keep the files in a stable location and do not rename or remove them while relying on the playlist.
Configure OBS to stream to YouTube
- In OBS, open Settings and select Stream. Choose YouTube as the service, then connect your account or enter the stream configuration and key from YouTube Studio. The precise available connection options can vary with OBS and YouTube interface changes.
- Open Settings → Output and configure the encoder. Open Settings → Video to set the output resolution and frame rate that match the content and connection you intend to use.
- Use RTMPS when available. YouTube recommends it for encoder ingest. Select a bitrate based on codec, resolution, and frame rate using the current YouTube encoder settings table; test your upload connection rather than assuming a nominal speed will be stable.
- For YouTube’s recommended H.264 settings, its current table lists 5 Mbps for 1080p at 30 fps and 6 Mbps for 1080p at 60 fps. For AV1 or H.265/HEVC, it lists 10 Mbps at 1080p30 and 12 Mbps at 1080p60. These are recommendations, not guarantees of uninterrupted delivery.
- Use CBR and set the keyframe interval to 2 seconds; YouTube recommends not exceeding 4 seconds. YouTube lists H.264, H.265/HEVC, and AV1 for RTMP/RTMPS, subject to encoder and system support.
- Apply the settings and verify the preview and audio before starting the stream.
Test the full loop before relying on it
- Play the entire playlist, including the last-to-first transition. Confirm each file is readable and the sound is neither missing nor unexpectedly loud.
- Check YouTube’s Live Control Room preview, then view and listen to the stream from a viewer page and, where relevant, a mobile device.
- Test with movement and audio similar to the real stream, and check upload capacity. YouTube advises testing the stream before launch and monitoring audio and video quality.
- If running a scheduled event, YouTube recommends setting up the encoder stream at least two hours ahead and starting the encoder at least 15 minutes before the scheduled start. This is preflight guidance for a scheduled event, not a rule that every 24/7 stream must be scheduled that way.
- If you rely on a local archive, check that it is being created and growing as expected. Do not assume the live stream itself guarantees an archive.
Keep the computer awake, use a stable wired connection where practical, preserve the source files, and decide who will respond if playback or ingest stops. These are operating precautions, not an OBS uptime guarantee. YouTube’s encoder documentation also discusses backup-ingest concepts; enabling a playlist does not configure backup ingest or failover automatically. The cited YouTube and OBS guidance does not establish a guaranteed maximum continuous runtime for this setup.

Troubleshooting common failures
| Symptom | Likely cause | What to check |
|---|---|---|
| VLC Video Source is missing or does not load | VLC is not installed, or its architecture does not match OBS. | Install VLC; for 64-bit OBS, install 64-bit VLC, then reopen OBS. |
| A file plays, but the playlist does not restart | Loop Playlist is not enabled, or the source is configured differently than intended. | Open the VLC Video Source properties, enable Loop Playlist, and test through the final file. |
| A playlist item is black, silent, or stops early | The file may be unavailable, unreadable, or otherwise incompatible with the source. | Confirm the file path and that the file plays through its end; keep files in stable locations and test each item in OBS. |
| YouTube does not receive the stream | The channel may not yet be enabled for live streaming, the stream key/configuration may be incorrect, or the connection may be unavailable. | Confirm channel eligibility and activation, recheck the stream configuration in YouTube Studio, and verify OBS’s streaming status. |
| Stream health is poor or viewers see interruptions | Upload capacity or network stability may not support the selected output, or OBS/YouTube ingest may have stopped. | Test the connection, use an appropriate bitrate from YouTube’s settings table, and monitor OBS and Live Control Room. A local loop cannot repair a computer, network, power, or ingest failure. |
