AudioVideoExample demonstrates synchronized audio/video playback with clock integration.

fun basicAudioVideoPlaybackWithClock()

Example: Basic synchronized audio/video playback with clock

fun basicAudioVideoPlaybackWithClock() {
    val videoPath = "path/to/video.mp4"

    // Setup audio
    val audioDecoder = AudioDecoder(videoPath)
    audioDecoder.open(44100, 2)

    val audioPlayer = AudioPlayer(44100, 2)
    audioPlayer.initialize()

    // Create AudioClock as master timing source
    val audioClock = AudioClock(audioPlayer)

    // Create VideoTexture with audio clock for sync
    // val videoTexture = VideoTexture(renderer, clock = audioClock)
    // videoTexture.load(videoPath)

    // Pre-fill and start
    repeat(3) { audioDecoder.decodeFrame()?.let { audioPlayer.queueAudioFrame(it) } }
    audioPlayer.play()
    // videoTexture.play()

    // Render loop: video auto-syncs to audio clock
    // audioPlayer.processBuffers()
    // while (audioPlayer.getFreeBufferCount() > 0) {
    //     audioDecoder.decodeFrame()?.let { audioPlayer.queueAudioFrame(it) }
    // }
    // videoTexture.update(commandBuffer)  // Syncs to audioClock internally

    audioPlayer.cleanup()
    audioDecoder.close()
