Quick wins for a faster PC:
Repair Windows errors before they cause bigger problemsFix Now →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →You can keep recorded lessons playing in a YouTube livestream by running OBS Studio on a Windows mini PC, looping a lesson file or playlist, and sending the stream to YouTube with its stream URL and key. The mini PC, OBS, lesson files, and internet connection must remain available for the stream to continue; YouTube’s automatic archive is documented for streams under 12 hours, so don’t count on a complete archive of a longer continuous broadcast.
Before you start
- A Windows mini PC running Windows 10 or 11, with a DirectX 10.1-compatible GPU. These are OBS’s baseline Windows requirements, not a guarantee that a particular mini PC can encode your lessons at your chosen resolution and frame rate. OBS notes that performance depends on the encoder, resolution, frame rate, and scene complexity. Check OBS system requirements.
- OBS Studio and the lesson video files stored on the PC.
- A stable internet connection with enough sustained upload capacity for the stream. Ethernet is a practical option where available, but it does not guarantee reliability; test the actual connection.
- A YouTube channel enabled for live streaming. First-time enablement may take up to 24 hours. See YouTube’s encoder setup guide.
- Permission to livestream every lesson, including its video, audio, images, and any other material it contains. Having a recording does not by itself establish that you have the rights to rebroadcast it.
Enable YouTube live streaming and create a stream
- In YouTube Studio, select Create → Go live. If the channel has never streamed, complete YouTube’s enablement process and allow up to 24 hours for access to become available.
- Create or schedule a stream in Live Control Room. Use the stream’s encoder details to copy its stream URL and stream key.
- Treat the stream key like a password. Anyone with access to it may be able to send video to your stream. Don’t publish it or include it in a screen recording.
YouTube recommends RTMPS, the secure extension of RTMP. Use the server URL and key provided for the stream in YouTube Studio. YouTube’s encoder instructions cover the connection workflow.
Set up OBS to loop a lesson
For one lesson file
- Open OBS and select the scene you intend to stream.
- In the Sources panel, select + and add a Media Source.
- Give the source a recognizable name, select the local lesson file, and enable Loop. Confirm the video and audio appear in the OBS preview.
- Check that the lesson fits the canvas as intended. If it has a different aspect ratio from the canvas, inspect the preview for cropping or empty space before going live.
For a playlist of lessons
- Install VLC if it is not already installed. In OBS, add a VLC Video source; VLC Video is available only when OBS can find VLC. On 64-bit OBS, OBS documents that 64-bit VLC is required.
- Add the lesson files to the source’s playlist in the order you want them to play.
- Enable Loop Playlist so OBS restarts the list after its last item.
- Preview the transition between lessons and check the audio level and aspect ratio across the entire playlist. A file that plays correctly on its own may still be missing, silent, or incorrectly framed in the sequence.
OBS documents the settings for Media Sources and VLC Video sources. Keep the lesson files at stable local paths; moving or renaming a file after configuring the source can leave OBS unable to find it.
Connect OBS to YouTube
- In OBS, open Settings → Stream.
- Choose YouTube as the service if it is available in the service list. If using a custom server configuration, enter the YouTube stream URL and stream key copied from Live Control Room.
- Apply the settings and save them. Keep the key private, especially if you use a shared Windows account or allow remote access to the mini PC.
- When ready to broadcast, select Start Streaming in OBS. Return to YouTube Live Control Room and wait for the incoming preview; check stream health before treating the broadcast as live and stable.
Choose video settings the mini PC and connection can sustain
Use a resolution and frame rate that suit the source material, encoder capacity, and sustained upload connection. YouTube’s published H.264 recommendations include these two common targets:

| Output target | YouTube H.264 video bitrate recommendation | Important qualification |
|---|---|---|
| 1080p at 30 fps | 5 Mbps | YouTube ingest recommendation; not a guarantee that the mini PC or connection can sustain it. |
| 1080p at 60 fps | 6 Mbps | YouTube ingest recommendation; not a guarantee that the mini PC or connection can sustain it. |
These figures are for H.264 video; they are not a universal setting for other resolutions, frame rates, or codecs. Consult YouTube’s current encoder settings and bitrate guidance for the target you select.
- In OBS, open Settings → Output and choose an encoder available on the mini PC. Encoder choices and performance depend on its hardware; do not assume a small computer can encode a given workload just because OBS opens.
- Set the output resolution and frame rate in Settings → Video to match a sensible target for the lesson and system. A static lecture may not need 60 fps; the lower frame rate can reduce the workload.
- In the output settings, set the H.264 video bitrate to the YouTube recommendation for the chosen target, provided the connection can sustain it with headroom. Audio uses additional bandwidth, and other devices sharing the connection can reduce available upload capacity.
- Test with a representative lesson segment, including movement, slides, and audio. Watch OBS for encoding or rendering strain and YouTube Live Control Room for stream-health warnings. Reduce resolution, frame rate, or bitrate if the system or connection cannot keep up.
Do not treat a short successful test as proof of continuous operation. A 24/7 schedule puts sustained load on the computer and network; test for the intended operating pattern before relying on it.

Run the stream continuously and plan for interruptions
For a local OBS setup, the mini PC must stay on, OBS must continue running, the lesson media must remain accessible, and the network must remain connected. Check Windows power settings so the PC does not sleep during the stream, and avoid restarts or updates that interrupt the broadcast. Keep the mini PC somewhere with adequate ventilation and monitor it periodically.
YouTube documents automatic archiving for streams under 12 hours. Do not assume that one continuous stream longer than 12 hours will produce a complete archive. If you need lesson recordings as separate files or a dependable archive, keep the original files and make a separate recording or publishing plan rather than relying on a long live broadcast’s archive.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Copyright and channel-policy checks for recorded lessons
Before broadcasting, confirm that you have permission to livestream the lesson recording and all included material. This includes background music, embedded video clips, images, and material supplied by another instructor or publisher. A video being available on your computer or previously uploaded does not establish that you may rebroadcast it.

Review YouTube’s current rules for live content and monetization separately. Copyright permission and compliance with channel policies are distinct questions; an encoder setup cannot resolve either one. For a practical preflight, use StreamNeo’s copyright safety checklist.
Cost and continuity trade-offs
A mini PC lets you control the media playlist locally, but its cost is more than the purchase price: the computer and network equipment must keep operating, and someone may need to maintain OBS, Windows, and the media files. An optional UPS can provide short-term power during some outages, but it does not guarantee stream continuity. Estimate upload time for your lesson library with the upload-time calculator, and compare ongoing local and cloud costs with the cloud vs PC cost calculator.
If you prefer a dedicated hardware encoder or another cloud service, verify its current capabilities, pricing, availability, and terms before choosing it. YouTube’s encoder directory lists options for prerecorded or 24/7 streaming, but their presence in the directory is not a guarantee about their present plans or service continuity. Consult YouTube’s encoder list.
Or let it run in the cloud
