Modpack Creators

Modpack Creators

Requirements

• Include MusicXCST on both client and server.
• Include Fabric API for Minecraft 26.1.2.
• Include GeckoLib 5.5.1 or newer.
• Match the Minecraft/Fabric version expected by the mod.

Redistribution

MusicXCST is all rights reserved unless a file states otherwise. Confirm redistribution permission before publishing a modpack that includes the jar.

Keep the license and third-party notice files with the mod distribution.

FFmpeg

Public MusicXCST jars do not bundle FFmpeg executables. Do not add FFmpeg binaries into the MusicXCST jar.

For a pack or server, decide whether users should:

• install system FFmpeg
• configure an explicit FFmpeg path
• use the explicit managed setup flow where supported
• use already-normalized .ogg files where possible

If a separate pack distribution includes FFmpeg outside the MusicXCST jar, include the matching FFmpeg notices, source/build links, configure flags, and checksums.

Public Server Defaults

Before shipping server configs, review:

• upload size limits
• duration limits
• per-player file limits
• total storage limits
• admin absolute path access
• player playback policies
• FFmpeg mode and managed download policy

Do not include copyrighted music unless the pack has permission to distribute it.
