VLCJ 流视频开始时间

Question

我正在尝试使用 vlcj 从某一分钟开始播放视频

我所拥有的一切都很好

public static void main(String[] args) throws Exception {
    System.setProperty("VLC_PLUGIN_PATH", "C:\\Program Files\\VideoLAN\\VLC\\plugins");
    File vlcInstallPath = new File("C:\\Program Files\\VideoLAN\\VLC");
    NativeLibrary.addSearchPath(
            RuntimeUtil.getLibVlcLibraryName(), vlcInstallPath.getAbsolutePath());
    Native.loadLibrary(RuntimeUtil.getLibVlcLibraryName(), LibVlc.class);
    LibXUtil.initialise();

    String[] media = {"C:\\clips\\clip.mp4"};

    String options = ":sout=#transcode{vcodec=h264,vb=100,venc=x264{profile=baseline},fps=10,width=1920,height=1080,acodec=mp3,ab=24,channels=1,samplerate=44100}:http{mux=ffmpeg{mux=flv},dst=:8080/";
    MediaPlayerFactory mediaPlayerFactory = new MediaPlayerFactory(media);
    HeadlessMediaPlayer mediaPlayer = mediaPlayerFactory.newHeadlessMediaPlayer();
    mediaPlayer.playMedia(media[0], options);
    Thread.currentThread().join();
}

但总是从头开始， 当我使用 VLC 媒体播放器启动流时。

我所期望的是，直播的时间一直在进行，每次我加入直播时，我都会跳到这个时间，但这并没有发生。 有什么方法可以实现吗？

如果没有，是否可以在某一分钟开始直播？

我试过了 mediaPlayer.setTime(100); 但是没有效果

How to understand the difference between the two online video: RTSP and HTTP?

    Native.loadLibrary(RuntimeUtil.getLibVlcLibraryName(), LibVlc.class);
    LibXUtil.initialise();

    String[] media = {"C:\\clips\\clip.mp4"};

    //String options = ":sout=#transcode{vcodec=h264,vb=100,venc=x264{profile=baseline},fps=10,width=1920,height=1080,acodec=mp3,ab=24,channels=1,samplerate=44100}:http{mux=ffmpeg{mux=flv},dst=:8090/";

private static String formatRtspStream(String serverAddress, int serverPort, String id) {
    StringBuilder sb = new StringBuilder(60);
    sb.append(":sout=#rtp{sdp=rtsp://@");
    sb.append(serverAddress);
    sb.append(':');
    sb.append(serverPort);
    sb.append('/');
    sb.append(id);
    sb.append("}");
    return sb.toString();
}
