To loop local MP3s on a YouTube internet radio stream, send your computer’s audio and a visual feed through a live-stream encoder, then connect that encoder to YouTube Live Control Room with a stream URL and key. The playlist-repeat and audio-routing steps depend on the player and encoder you choose, so verify those settings in their current documentation before relying on them. YouTube’s setup requires an eligible channel, and first-time live-stream enablement can take up to 24 hours.
What you need for an MP3 radio stream
An MP3 folder by itself is not a YouTube live stream. A computer-based encoder sends YouTube a combined feed: the audio from your playlist and a visual stream, such as a static image or other visual. YouTube’s encoder route is the relevant one for files stored on a computer; mobile and webcam routes do not themselves provide a way to play a local folder.

- A YouTube channel eligible to live stream.
- A computer with the MP3 files and an audio player that can repeat the folder.
- A live-stream encoder that can receive the player’s audio and provide a visual feed.
- A stable internet connection with enough upload capacity for the full stream bitrate.
YouTube’s official guidance describes the encoder and Live Control Room workflow, but it does not establish the current click-by-click procedure for repeating a folder in a particular player or routing that player’s audio into a particular encoder. Follow the chosen software’s own current instructions for those parts.

- Check channel eligibility. YouTube says the channel must be verified and have no live-streaming restrictions in the previous 90 days. Enable live streaming in advance; first-time enablement can take up to 24 hours. See YouTube’s live-streaming setup guidance.
- Open Live Control Room. Create a new stream or select an existing one. Use the stream’s title, visibility, and schedule settings that fit your broadcast.
- Copy the stream URL and key. In Live Control Room, get the connection details for the stream. Treat the key as a credential: it tells your encoder where to send the feed and lets YouTube accept it. Do not share it publicly.
- Enter the connection details in your encoder. Paste the stream URL and key into the encoder’s streaming destination fields. The exact field names vary by encoder.
- Send a preview before going live. Start the encoder’s connection and wait for the incoming feed to appear in Live Control Room. Check that both audio and the visual feed are present before starting the public stream.
Set the MP3 folder to repeat and route its sound
Configure the player
In your chosen audio player, import or open the folder and enable the setting that repeats the entire playlist or folder—not just the currently selected track. Player labels differ, so check the current documentation for terms such as “repeat all” or “loop playlist.” Confirm that playback advances through the last file and returns to the first.

Send player audio to the encoder
Configure the encoder to capture the computer’s playback audio, or use the audio-routing method documented for your player and encoder. Check the selected input device and operating-system permissions, then listen to the encoder’s audio meter or preview. Do not assume that selecting a microphone will capture the MP3 player; it may instead capture room sound.
Provide a visual feed as well as audio. The encoder’s own documentation should explain how to add a still image or other suitable visual source and how to combine it with the captured audio. Check that the visual remains present when the playlist changes tracks.

Recommended audio and connection checks
- Audio encoding: YouTube recommends 128 Kbps stereo audio and a 44.1 kHz stereo sample rate in its encoder settings guidance. Treat these as platform recommendations, not guaranteed minimums or a promise of a particular sound quality.
- Upload bandwidth: The connection’s available upload capacity should exceed the total stream bitrate. YouTube recommends keeping 20% headroom, according to its streaming tips. Leave capacity for normal network variation rather than setting the stream at the full measured upload rate.
- Test the whole chain: Play the actual files, inspect the encoder’s audio and video preview, and monitor stream health in Live Control Room. YouTube advises testing before a scheduled broadcast; its guidance says to set up encoders at least two hours before a scheduled stream and start them at least 15 minutes beforehand. Those timings help with preflight but do not guarantee uninterrupted operation.
Check music rights before you go live
Only stream music you have the necessary rights to use. YouTube states: “All live streams are scanned for matches to third-party content, including copyrighted content in the form of another live broadcast.” Its systems may replace a stream with a placeholder, warn you to stop using the content, temporarily interrupt or terminate the stream, or terminate it following a copyright or Community Guidelines strike. Read YouTube’s copyright guidance for live streams.

One-click scans. No signup required.
If you have licensed third-party music, ask the rights owner to add your channel to the Content ID allowlist. YouTube says a license alone may not prevent interruption when the channel is not allowlisted. Its livestream terms and conditions place responsibility on the provider to have the necessary rights, including music licensing rights; this is YouTube’s stated terms language, not individualized legal advice.

Troubleshoot common problems
| Symptom | What to check | Next step |
|---|---|---|
| YouTube does not receive a signal | Confirm live streaming is enabled, the encoder is running, and the stream URL and key match the selected stream. | Reconnect using the correct Live Control Room details, then wait for the preview before going live. |
| The stream has video but no music | Check that the encoder is capturing the player’s output rather than an inactive or incorrect input. | Use the player-and-encoder documentation to select the correct system-audio routing method; verify sound in the encoder preview. |
| The stream has sound but no usable visual | Check that a video source is configured and visible in the encoder preview. | Add or restore a supported visual source using the encoder’s instructions, then preview again. |
| The playlist stops at the last MP3 | Check whether the player is set to repeat one track, repeat the playlist, or stop after the queue. | Enable repeat-all/loop-playlist in that player and test that playback returns to the first file. |
| Playback or stream health is unstable | Compare available upload capacity with the total stream bitrate and check Live Control Room’s stream-health indicators. | Reduce competing network traffic or lower the encoder’s bitrate, then test again while preserving YouTube’s recommended 20% upload headroom. |
| YouTube interrupts or replaces the stream | Check for a copyright notice or other Live Control Room warning. | Stop using material you are not authorized to stream. For licensed third-party music, ask the rights owner to allowlist the channel through Content ID. |
