To loop a recorded lesson on YouTube Live from a Windows PC, add it to an OBS Media Source, enable Loop, connect OBS to a YouTube encoder stream with your stream key, and start streaming. That repeats the video; it does not keep Windows, OBS, your internet connection, or power running around the clock. The settings below follow YouTube’s general encoder guidance, not India-specific network requirements.

Before you configure OBS

  • Your YouTube channel must be verified and have no live-streaming restrictions in the preceding 90 days.
  • If you are enabling live streaming for the first time, YouTube says activation may take up to 24 hours. Set it up before the planned broadcast.
  • Use a Windows PC that can play the lesson and encode the stream, plus an internet connection with enough stable upload capacity for your chosen bitrate.

YouTube does not publish a special OBS profile for India. Measure and test the actual upload connection you will use; the country alone cannot establish what bitrate it can sustain.

Set up a single lesson to repeat in OBS

  1. Open or create a scene. In OBS Studio, select the scene where the lesson should appear.
  2. Add the video. In Sources, choose + > Media Source, create or select a source, then browse to the lesson file. OBS supports common local video formats, including MP4.
  3. Enable looping. In the Media Source properties, turn on Loop. OBS will replay the file when it reaches the end.
  4. Check restart behavior. Restart playback when source becomes active is On by default. Leave it enabled if the lesson should begin at the start whenever the source becomes active.
  5. Verify picture and sound. Check the OBS preview for framing, legibility, and audio before streaming. Listen to the lesson itself, not only a silent or static opening frame.

For a sequence of lessons rather than one repeating file, add an OBS VLC Video source and configure a playlist. Its Loop Playlist option is On by default. VLC must be installed; OBS notes that 64-bit OBS requires 64-bit VLC. Test transitions and audio between files before going live.

Connect OBS to a YouTube encoder stream

  1. Open YouTube Studio’s Live Control Room and create or select an encoder stream.
  2. Copy the stream URL and stream key shown for that stream.
  3. In OBS, open Settings > Stream, choose YouTube or RTMPS when available, and enter the server URL and stream key. If OBS offers a YouTube account connection instead, use the encoder stream details required by your setup.
  4. Keep the stream key private. YouTube describes stream keys as password-like credentials that tell YouTube where the encoder sends its feed and allow YouTube to accept it. If exposed, replace or reset it in YouTube Studio before using it again.

Choose bitrate and encoder settings

YouTube’s encoder-settings guidance accessed in 2026 lists 5 Mbps minimum and 14 Mbps recommended for H.264 at 1080p30. These are YouTube’s platform recommendations, not a guarantee that your PC or internet connection can sustain that rate.

#1 Best Overall
Cable Matters 10Gbps Snagless Cat 6 Ethernet Cable, 25ft, Black
  • High-Performance Connectivity: This Cat 6 ethernet cable is designed for superior performance, with a 24 AWG copper wire core. It provides universal connectivity as an ethernet cord for LAN network components such as PCs, servers, printers, routers, and more, ensuring reliable and fast network connections
  • Advanced Cat6 Technology: Experience Cat6 performance with higher bandwidth at a Cat5e price. This network cable is future-proof, ready for 10-Gigabit Ethernet and backwards compatible with any existing Cat 5 cable network. It meets or exceeds Category 6 performance according to the TIA/EIA 568-C.2 standard
  • Reliable Wired Network Solution: Known variously as a Cat6 network cable, ethernet cable Cat 6, or Cat 6 data/LAN cable, this RJ45 cable offers a more secure and reliable connection than wireless networks. It's ideal for internet connections that demand consistency and security
  • Durable and Secure Design: The connectors of this ethernet cable feature gold-plated contacts and strain-relief boots for enhanced durability. Bare copper conductors not only improve cable performance but also comply with communication cable specifications
  • High-Speed Data Transfer: With up to 550 MHz bandwidth, this ethernet cord is ideal for server applications, cloud computing, video surveillance, and streaming high-definition video. It also supports Power over Ethernet (PoE, PoE+, PoE++) for powering devices like IP cameras, VoIP phones, and wireless access points, ensuring fast and reliable network performance.
Setting Practical starting point Guidance
Video codec and mode H.264, CBR YouTube recommends CBR for live encoding.
Resolution and frame rate Use a profile suited to the source and connection; for 1080p30, use the bitrate guidance above as a reference. YouTube’s cited bitrate values apply to 1080p30 H.264, not every resolution or frame rate.
Keyframe interval 2 seconds YouTube recommends 2 seconds and says not to exceed 4 seconds.
Audio codec AAC or MP3 Both are supported for RTMP/RTMPS audio.
SDR color Rec. 709, 8-bit YouTube specifies these for SDR. Use HDR only if the source, hardware encoder, and workflow support it.

Set bitrate according to the upload capacity available during the broadcast, not just the result of a one-time speed test. YouTube recommends leaving 20% upload-bandwidth headroom. For example, a stream set to 5 Mbps calls for about 6.25 Mbps of available upload capacity to preserve that margin; this is arithmetic from YouTube’s recommendation, not an ISP guarantee. If the connection is shared or varies, reduce bitrate or resolution and test under representative conditions.

Test the stream before relying on it

  1. Start the encoder from OBS and check the stream preview in YouTube Live Control Room before making it public.
  2. Confirm the intended audience can see the broadcast with the visibility setting you selected.
  3. Watch a section with motion and listen for the lesson’s embedded audio. Check that playback returns to the beginning when the file ends, or that the playlist advances and loops as intended.
  4. Monitor YouTube’s stream health and audio/video quality during the test. Repeat the test on the same PC and network you expect to use.

What “24/7” requires beyond the loop

The OBS loop repeats a media file; it is not a recovery system for OBS crashes, Windows restarts, internet outages, or power loss. YouTube warns that a network disruption can break a live stream. A truly unattended local setup therefore needs separately planned power and network continuity, plus a tested way to recover after software or system failure. The cited official guidance does not establish a Windows sleep-prevention path or guarantee automatic restart or 24/7 availability. Do not treat the Loop checkbox as an uptime guarantee.

Troubleshooting common problems

Symptom Likely cause What to check
You cannot start a YouTube encoder stream Live streaming is not enabled, the channel is not verified, or a restriction applies. Check channel eligibility in YouTube Studio. First-time activation can take up to 24 hours.
YouTube receives no feed or rejects the encoder The wrong stream URL or key was entered, or the key was changed. Copy the URL and key from the selected Live Control Room encoder stream and update OBS. Keep the key private.
The stream buffers or loses health Bitrate exceeds stable upload capacity, the connection is shared, or connectivity is disrupted. Reduce bitrate or resolution, retain YouTube’s recommended 20% upload headroom, and retest on the broadcast connection.
The lesson plays once and stops The Media Source Loop option is off, or a different source is in use. Open the Media Source properties and enable Loop. For a playlist, check Loop Playlist on the VLC Video source.
A playlist source is unavailable VLC is not installed or its architecture does not match OBS. Install VLC; OBS specifies 64-bit VLC for 64-bit OBS.
Video is visible but lesson audio is missing The source or encoder audio path may not be delivering the lesson sound. Listen in OBS preview, inspect audio activity, then verify audio in the YouTube preview before relying on the broadcast.
