Minecraft Fabric Mod: Jockey Radio

Create a disc, place it in a jukebox, and nearby players hear the audio through Simple Voice Chat. Players listen with the standard Simple Voice Chat client, so no other client mod is needed.

Audio sources

Each radio disc plays one source:

• HLS and internet radio: HLS playlists, SavePoint station streams, Icecast streams, HTTP audio, and

  compatible broadcast endpoints.

• RTMP receive: the Minecraft server becomes an RTMP ingest endpoint, so you can broadcast directly from

  OBS, SavePoint, or other broadcasting software or relays.

• Direct URLs and local audio: play a direct audio URL or loop a file kept on the server.

• SavePoint: connect a SavePoint station over HLS, or push a live SavePoint broadcast into Minecraft over

  RTMP. The Now Playing API shows the current track in the boss bar.

The /jockey disc manager

Operators run /jockey to open the server-side disc manager. From it they can:

• Create, edit, test, give, and delete radio discs
• Set an audible radius for each disc
• Choose each disc’s appearance, display name, color, and text style
• Copy the RTMP server, stream key, and full ingest URL
• Configure now-playing metadata and marquee templates
• See live, idle, and buffering states
• Run several stations and jukeboxes at the same time

Radio discs remain ordinary Minecraft music-disc items. Inserting one starts its source, and ejecting it stops playback.

Requirements

On the server:

• Minecraft 26.2
• Fabric Loader 0.19.3 or newer
• Fabric API
• Simple Voice Chat 2.6.21 or newer
• Java 25

Players need the normal Simple Voice Chat client and its dependencies. If game sounds play in your headphones but the radio plays on your speakers, set Simple Voice Chat’s output device to your headphones.

Bundled media tools

The release jar bundles ffmpeg, for decoding and RTMP ingest, and yt-dlp, for optional platform-link resolution. They extract into the server configuration directory on first use, so the mod runs on managed hosts that offer no shell access. Server operators can turn the bundled binaries off and provide their own executable paths instead. The release includes third-party notices and license texts.

Platform links

Platform-link resolution is off unless a server operator sets enablePlatformLinks. Before turning it on, the operator must review the terms of service of every platform they intend to use and confirm they hold the rights to rebroadcast the selected content. Jockey Radio distributes no audio, grants no rebroadcasting rights, and is not affiliated with or endorsed by any of those platforms.

Scaling

Jockey Radio has not yet been load-tested at large-server scale. Testing so far covers four to six simultaneous audio sources on the development host. Jukeboxes playing the same disc share one upstream feed, but each active jukebox still needs its own encoder and Simple Voice Chat channel. Increase usage gradually while watching server tick time, CPU, memory, and network traffic.
