.package(url: "https://gitlab.com/bithuman/sdk/homebrew-bithuman",
         from: "2.22.1")

let engine = try Expression2Engine.create(
    avatarContainer: avatarURL,
    sharedEngineContainer: sharedEngineURL,
    stagingDir: stagingURL)

engine.feed(samples)
engine.flushTail()
for await frame in engine.frames(audioClock: { played() }) {
    show(frame.bgr, frame.width, frame.height)
    if frame.audioTime == 0 { play(reply) }
    if frame.endsReply { break }
}

implementation("ai.bithuman:expression2-android:0.6.2")

Expression2Avatar.create(context, model, Expression2Options()).use { avatar ->
    val frame = avatar.newFrameBitmap()
    avatar.feed(pcm16k)
    avatar.flushTail()
    while (true) {
        if (avatar.pull(frame) != null) { show(frame); continue }
        if (!avatar.hasPendingTail && avatar.queuedFrames == 0) break
        Thread.sleep(10)
    }
}

show, play and played are your app's own. You bring the conversation.

That's the whole loop.
