javax.media.NoPlayerException：找不到播放器：vfw：// 0

Question

我在以下代码中收到错误：

private void initCamera() throws IOException, NoPlayerException, CannotRealizeException
{
    MediaLocator ml = new MediaLocator("vfw://0");
    player = Manager.createRealizedPlayer(ml);
    this.tbCamera.add(player.getVisualComponent());
    player.start();
}

以下是追踪：

SEVERE: null
javax.media.NoPlayerException: Cannot find a Player for :vfw://0

at attendancemanagement.Student.initCamera(Student.java:67)
at attendancemanagement.Student.<init>(Student.java:52)
at attendancemanagement.Student.main(Student.java:294)

this没有帮助我。
