Question

我正在编写一个从相机（Live! Cam sync hd creative）流式传输视频的小型应用程序。我正在使用VLCj库。在控制台中出现一段时间

[0494a9bc] main input error: ES_OUT_SET_(GROUP_)PCR  is called too late (jitter of 154 ms ignored)
[0494a9bc] main input error: ES_OUT_RESET_PCR called

应用程序在约2000ms

时崩溃

public class CameraServer {
    private MediaPlayerFactory factory;
    private HeadlessMediaPlayer mediaPlayer;
    private CanvasVideoSurface videoSurface;


    public CameraServer(){
        factory = new MediaPlayerFactory();

        // Create player.
        mediaPlayer = factory.newHeadlessMediaPlayer();
    }

    public void start(){
        // Select input device.
        String mrl = "dshow://";
        // Tweak the options depending on your encoding requirements and audio
        String[] options = {":sout=#transcode{vcodec=mp2v,fps=30, width=640, height=640}" + formatHttpStream("127.0.0.1", 5555), "no-sout-audio", "clock-jitter=0"};
        mediaPlayer.playMedia(mrl, options);
    }

    private static String formatHttpStream(String serverAddress, int serverPort) {
        StringBuilder sb = new StringBuilder(60);
        sb.append(":duplicate{dst=std{access=http,mux=ts,");
        sb.append("dst=");
        sb.append(serverAddress);
        sb.append(':');
        sb.append(serverPort);
        sb.append("}}");
        return sb.toString();
    }
}

我已经尝试了不同的选择。什么可能是错的？

修改

只有在Windows上编译时才会发生。在Linux上一切正常但它必须在Windows上运行。
