Java Discord Audio & Video Encryption (JDAVE)

This library provides java bindings for libdave.

To implement these bindings, this library uses Java Foreign Function & Memory API (FFM).

Requirements

• Java 25

Supported Platforms

• Linux x64

Example: JDA

To use this library with JDA, you can use the JDaveSessionFactory to configure the audio module:

JDABuilder.createLight(TOKEN)
  .setAudioModuleConfig(new AudioModuleConfig()
    .withDaveSessionFactory(new JDaveSessionFactory()))
  .build()

Why Java 25?

This library uses the Foreign Function & Memory (FFM) API which has been stabilized in Java 22. Since Java 22 is not a Long-Term-Support release, this library instead uses Java 25.

Other alternatives have downsides compared to the newer FFM API:

• JNI breaks relocation, since it requires the package to match the C symbols. To relocate a JNI native binding, you must rename the native symbols, which is quite cumbersome.
• JNI requires compiling the library for each platform, we can't just call C libraries directly without some C glue code that needs to be compiled for every target platform.
• JNA can be relocated and does not require extra C glue code, but has significant overhead, which is a problem in performance critical hot paths, like with audio encryption.
• JNA is also a massive library, which is a dependency we can avoid by using Java's standard library entirely.

For this reason, I've chosen to use the new FFM API instead. The optimal solution would be a full Java implementation, instead of relying on native libraries. But that requires a lot more time, which we don't have right now.
